What is carbon monoxide and how does it originate?

carbon monoxide is formed during burning of exhaust gases and it also occurs in nature. Among other things, mines, caves etc. are mentioned here.

Ei Electronics Ei 207 D Carbon monoxide detector (with LCD display, for home, camping and boat, 7 years product life) white, 1 piece [energy class A]In general carbon monoxide can also be found in industrial exhaust gases after sample and measurement. It is caused by fires as well as by an improper running function of wood-, gas- or coal ovens or grills.

Also, fireplaces, that have been improperly fired or installed turn out to be one of the most important causes for carbon monoxide poisoning according to CO detector test and trials.

Death goes unnoticed…

carbon monoxide is a colorless gas, which is odorless, invisible and literally not graspable.

Ei Electronics Ei 207 D Carbon monoxide detector (with LCD display, for home, camping and boat, 7 years product life) white, 1 piece [energy class A]At carbon monoxide, CO, is an extremely toxic gas, which virtually displaces the oxygen from blood which is vital for people.

The gas is composed of carbon and oxygen and has quite large similarities with the oxygen moleculeO2 -.

And this is exactly where the Krux: Precisely because the similarity to the essential oxygen is so great, the CO or Carbon monoxide quite easily instead of oxygen to anchor to elementary structures in human metabolism.

In this way, the gas, which we need for breathing is successively displaced and carbon monoxide poisoning occurs in the course of this.

By the way, carbon monoxide is also known in professional circles as conceptuality carbon monoxide, whereas poisoning with CO is usually known as carbon monoxide intoxication.

What is a CO detector?

According to the online test, a CO detector or carbon monoxide detector is a small, usually very handy device that can be placed on the ceiling, on the wall or – depending on model – also on a table.

KIDDE CO-Alarm X10-D with display Carbon monoxide detector, white, 13775In most German states it is now mandatory to have such a device. In approach the fact that today in more and more households a fireplace or still a gas heating are present, it is obvious that sooner or later such a legislation will be passed.

Because if chimneys, chimneys, gas heatings and the like, for whatever reasons always, too much carbon monoxide secrete, this is not noticed by people.

Indeed, carbon monoxide is a gas, that is colorless, odorless and perfectly tasteless. However, it prevents absorption of oxygen in the blood. This has the consequence that the human in a overdose of CO or carbon monoxide passes out and suffocates in the course of this.

Fact is according to various samples and experiments that you generally not notice if the CO content in a spatiality is too high. Death as a result of carbon monoxide poisoning is, as far as we currently know, painless and occurs suddenly – i.e. not perceptibly -.

When dizziness or nausea occurs, it is usually too late, and powerlessness occurs. Because an increased CO content within rooms is usually noticed much too late, the purchase of a CO detector with a low price is worthwhile. So you benefit in many ways Hinsicht from the practical and especially life-saving devices.

Small, but indispensable

KIDDE CO alarm X10-D with display Carbon monoxide detector, white, 13775A favourable CO detector with the best test result in an analysis is usually very small and handy – about the size of a palm – and only little centimeter high. Also the selfweight of these functional life savers often lies not above 200 gram.

By special sensors, located in inside of CO detector, the device can immediately detect if the carbon monoxide concentration in a room of your household is unusually high.

Thus the measurement of the CO content in the respective room of the own household takes place almost continuously.

However, it is worth knowing in this context that a reliable and above all meaningful measurement of the carbon monoxide content in the ambient air can only actually take place if the performance of a CO detector from a well-known manufacturer is correspondingly high.

Since most of these devices are equipped with batteries, it is possible that the power portfolio and thus the reliability may leave something to be desired, if the batteries discharge with the time.

Therefore, it is all the more important to take the batteries regular to test and in eye . This allows you to test to what extent they are still powerful or whether they may need to be replaced by new ones.

How does a CO detector work?

Anyone who believes that the functionality of a CO detector with the best test grade in the test result of the evaluation is complicated is mistaken. The fact is that the modern CO detectors are test winners from the external test with a special sensor cell equipped. These mostly work on the basis of Sn02, tin dioxide.

This means that this material causes the carbon monoxide, which gets into the proximity of the SN02 to oxidize. As a result, the conductivity of the sensor cell changes, whereupon the resulting change of the resistance is analyzed and evaluated.

X-Sense Carbon Monoxide Detector CO Detector / Warning Device Warning Device Carbon Monoxide CO Detector with Digital Display, CO03JFThis procedure runs in fraction lesser seconds ab> fraction less seconds this fraction fraction fraction If the CO-concentration of the carbon monoxide is 100 ppm, i.e. if it exceeds the human hazard measure, then the CO detector or warning detector will almost immediately emit a alarm according to the evaluation of an external test run.

However, if the CO concentration of carbon monoxide is present, but only in a literally vanishing low quantity in the ambient air when compared, the CO concentration of the carbon monoxide is present, the Alarm of the transmitter is audible only after expiration of a certain period.

Check functionality regularly

In this context it is important to remember that everyone human with breathing air emits low measure to CO. If the alarm were to give warning therefore even at lowest doses alarm, the beep of the CO alarm would be heard throughout the day with good overall grade in the product test.

Therefore the CO detectors are designed in the form , that they only give alarm when the amount of carbon monoxide in the air assumes dangerous dimensions.

The sensor cell consisting of said tin dioxide remains not “fresh” over many years, but rather it has to be considered that the qualitative characteristics resp. the value of such a device after expiration decreases from about five to 10 years and thus also the reliability leaves something to be desired.

Therefore recommend we recommend replacing the CO detector with a good overall score in the experiment at the latest after ten years with a new device with a loud alarm after CO detector. And don't forget other the regular replacement of batteries.

If these not are replaced by time at time by new ones, this must also be assumed, that an optimal and above all accurate measurement of the carbon monoxide content in the air not or only in inadequate measurements can take place.

It is advisable to check the batteries in the meantime with a battery measuring instrument and in the course of this also to check the functionality of the CO detector. In this way, you play it safe from the start.

Advantages and areas of application

A CO detector is today elementary in every household and in every commercial used building. So it is not surprising not, that legislation is currently designed accordingly, that in most federal states it is prescribed by legislator even that smoking or CO detectors must be installed.

Abus Carbon monoxide detector COWM300, 37241The developments with regard to beautiful living in run of the recent past speak for themselves. So more and more people attach great importance to a modern and above all comfortable as well as technically best possible mature flat.

Homes – whether old or new buildings – are equipped with chimneys as well as chimneys and most modern heating, thermo- and climate technologies . Also the crackling fire in a decoratively conceived fireplace wants to do almost none more today.

When it comes to monitoring and technical control of a chimney , the chimney sweep literally passes by “all years again” and the performance or chimney . which measures calorific values and the like.

For this reason alone, the risk of carbon monoxide poisoning or overloading can be reduced to a minimum level. Nevertheless, you should never be 100 percent safe, but always rely on the additional support of a CO detector.

You can't do it without her…

Abus Carbon monoxide detector COWM300, 37241Other the whole looks with look at the firing of chimneys. The chimney sweep also comes here in certain regular distances to check the functionality and the performance portfolio.

The fact is, however, that the owner of a chimney operates the device himself. This means he lays fire, lays firewood after, regulates the temperature control and the like. So someone is handling the chimney, who does not have a corresponding qualification.

According to an external survey, this makes the risk of a possible carbon monoxide load of the ambient air quite considerable. Because what if operating errors result in technical defects and CO is the result?

Everywhere vital – CO detector

Another important location for CO detectors is the garage or the underground garage and areas, where heaters, boilers and similar technical devices are present. Not to forget the wine cellars in the well-known wine-growing regions of the country.

In the course of wine production in past , one or the other accident has indeed already occurred because the effect was underestimated by CO. Or the mostly private operators had not reckoned with the occurrence of carbon monoxide within their production activity.

Thus, according to the test run and external survey, the use functional smoke- and CO detector are particularly suitable in this range.

What types of CO detectors are there?

When it comes to safety and protection of humans, especially within their own four walls, you should leave nothing to chance. The claims of the consumers are today very high, and so it is not surprising, that also the offer variety of the carbon monoxide detectors has become test winners and comparison winners to this day extremely versatile.

different species of smoking- and fire detectors have therefore established themselves on the market, whereby in this context we are talking about following species:

  • CO detector
  • Heat detector
  • Fire detector
  • Smoke detector
CO Detectors Test winners and comparison winners are still relatively new on the market, but they enjoy demanding consumers a very large popularity.

Due to their special conception and the implemented sensor for the alarm, they contribute to a possible higher carbon monoxide content being reported immediately in a spatiality.

In approach the fact that carbon monoxide is odour- and colourless as well as generally not perceptible, the installation of a CO detector is absolutely recommended.

As soon as an unusual high temperature is registered in a room, the heat detector alarm strikes. Again and again it appears that a fire, if it has broken out in a flat or a building is not immediately noticed.

This is the case, for example, when residents of the night sleep. In this respect, a heat detector with a view to a timely protection of inhabitants of a building represents a very helpful and well-thought-out acquisition.

A fire detector gives alarm, as soon as a building or room fire has broken out. In comparison to the heat detector, which reacts primarily to temperature changes, the fire detector strikes on the basis changed light conditions. Test and compare the models yourself in product tests, investigations, product tests, comparison tables and practical tests on the Internet! After inspection, consideration and control you will find a product in accordance with your wishes!
Surely a Alarming at Light switching on and off does not have to be expected, because these Factors are generally considered. However, if flames are noticed, loud alarm tone is heard.
The Smoke detector “does not wait” until the first flames blaze in congruence until the first flames blaze, but strikes according to test reports and comparison tables occurrence of Qualm or damping.

In this respect, the smoke detector is more of a advantage, when compared with a fire detector.

As efficient and helpful as all devices this product category are, you can usually handle them as easily as .

So you can simply fix them on the ceiling or on the wall and usually rely on their high functionality. It is only important that you take battery-powered devices regularly in eye .

So the CO detectors were tested in tests

It is important that in the case of a CO detector, test winner and comparison winner from tests, if possible, everything is “coherent”. After all, devices like these are vital.

Particularly in particularly endangered areas, such as buildings with chimneys, with outdated chimneys, with gas heaters and the like, special caution is required.

Therefore, CO detectors were taken in relation to the following test criteria in eye :

Test Criterion: Reliability

If you choose the Purchase of a CO detector test winner , you should be able to rely on the safe and reliable mode of operation from start on.

Accordingly, the aspect the reliability in the context of the individual CO detector tests was always particularly in the focus.

Test criterion: Handling

Smartwares Carbon Monoxide Detector with Display and Temperature Display, Test Button, RM370 TestTo get the most out of functionality, handling should be as consumer-oriented as possible.

This means in congruence that the user should not have completed a “technical study” first, but that only a few handholds should be required before the CO detector is ready for use.

It is equally important that the menu design is clearly structured. There are many test devices where the corresponding values can be read on the display. If the menu navigation is too complicated, this could lead the consumer completely wrong.

Test criterion: Installation

The installation should be simple and uncomplicated. Ideally, the accessory portfolio with view on small tools is included in the scope of supply.

The simpler the installation is on the ceiling or on the wall, the is more likely to speak for the product.

Test criterion: Functionality

A CO detector test winner from the online test should give not only alarm if the carbon monoxide content assumes a spatiality conspicuous dimensions. However, the functionality not should be limited to the alarm alone, but rather the user should also have further possibilities of use.

In this regard, it is also important that the values measured in the ambient air can be called up successively.

The larger the display and the easier the indications were readable, the better the CO detector was evaluated as test winner in the test.

Test criterion: Service life

Generally, a CO detector between 5 and 10 years is long lasting. Certainly, the characteristics of the corpus' itself is longer, but here the focus is on the conception of the sensor.

It is therefore a good idea to focus on high-quality products, which are characterized by a particularly powerful and above all durable core.

In the case of inferior CO measuring instruments, additives may be present which impair the quality of the instrument overall.

Test criterion: Energy consumption

Although for the higher CO detectors you usually have to dig a little deeper into your pocket, the “extra effort” is well worth it.

Because in approach a modern condition and a user-friendly construction energy consumption is – no matter whether battery or mains – relatively gering. Therefore the test also focused on energy consumption.

Test criterion: Volume

The most reliable alarm is of little use if the volume is too low.

Certainly, this can be regulated at modern CO detectors at at will, but on the other hand tests and experiments often showed that the alarm tone was sometimes too quiet.

CO detector tested by Stiftung Warentest Partner

The Stiftung Warentest has not yet tested any CO detectors itself, but has already announced that CO detectors are on the “wish list” of products to be tested. However, in 2016 a partner organisation, the Dutch consumer magazine Consumentengids CO detector, tested. Of the 19 CO detectors tested, most are also available in Germany.

As it turned out, the CO detector test was very important, because equal to two of the tested CO detectors did not set an alarm at a too high carbon monoxide value. Based on this test, both manufacturers (J & S Supply and Pentagon) responded immediately and recalled their models from the market. The Stiftung Warentest-Partner Criticism also used a model of Brennenstuhl, the CO detector BCN1221: although the CO detector reliably reported carbon monoxide, it also rejected small (harmless) amounts. According to Consumentengids this is not acceptable, because there is a danger that the owners are annoyed by too frequent alarms and then no longer trust the alarm in an emergency.

Among the CO detectors recommended by the magazine after their three-month test were the models of Kidde and Ei Electronics. You will already find the successor models of these brands in our list of review institutes.

You can find the complete test report here (in Dutch language).

What do I have to pay attention to when buying a CO detector?

Watch When Purchase a CO detector, primarily check whether the device corresponds to the possible measuring range the spatial situations for which it is intended.

Thus, today practical detectors are available which are designed in form, that they are designed for need for smaller or also for large rooms.

So the reliability for a CO detector intended for a large room would not be reliable enough in a small room.

Conversely, an optimal size-oriented design of the CO detector should always be observed.

If you also want a device that is as easy to use as possible, you will easily find it in view of the huge selection today, as well as interested consumers, who want a CO detector with manifold technical refinements.

Here, for example, it also depends on the condition of the control panel.

Depends on different factors

Assuming that the menu navigation is too confusing, it is possible that the technically less experienced user may have circumstances problems with handling.

The continue it is essential that also the size of the display leaves nothing to be desired. If, for example, you have opted for a CO detector where you can read the corresponding carbon monoxide values according to need, this information should be as visible as possible.

Ideally, according to the online comparison, juxtaposition and suitability test, a illuminated display is available. If your visibility leaves something to be desired under circumstances, you should always pay attention to the size and ideally also to an existing LED illumination when purchasing such a device.

This makes it even easier to handle the CO detector. Important is not lastly the design of the battery compartment: This should be as easy to open and close as possible, especially with an untrained consumer,, but at the same time convince with a reliable closing mechanism.

Finally, the batteries should not fail sooner or later , if the CO detector is attached to the ceiling or to the wall fixed.

Short information about leading manufacturers

  • Abus
  • FireAngel
  • Kidde
  • Dräger
  • Elro
Already since year 1924 the company Abus exists on the market. Until today a whole company group has even established itself, whereby ABUS Security Center GmbH and Co. KG, ABUS Seccor, ABUS August Bremicker Söhne KG and ABUS Pfaffenhain GmbH belong to company.

Not only CO detectors belong to the multi-faceted product program, but also elevators, solutions for an adequate object protection as well as burglar protection devices, alarm systems and the like.

Currently far more than 3,000 employees are employed for the Abus group.

FireAngel is a well-known company headquartered in United Kingdom, that has been in business since establishment by Same Tate and Nick Rutter, to produce and market first-class smoke- and CO detectors, and at the same time to convince with a moderates price structure.

The company is even represented worldwide with no less than 50 different patents. We also work closely with British Firefighters to ensure Optimum on Service and Performance .

Kidde United Technologies has been on the market for more than 50 years. Also in Germany the group has a branch of business, whereby it is a national as well as international concern to offer the person an optimal protection and the best possible security. Test and compare the models yourself in product tests, analyses, studies, comparison tables and practical tests on the Internet! After inspection, consideration and control you will find a product in accordance with your wishes!

Until today over one million customers belong to the circle of satisfied consumers, who are interested in alarm and safety devices from the home Kidde.

When it comes to medicine- and security technology, the bandwidth of the Dräger company is impressively large. Among other things, equipment is produced with a view to fire protection, medicine- and rescue technology, which can be purchased in numerous countries.

Already since 1889 one knows the German brand and until today one knows that Dräger belongs to the prominent company in the industry.

More than 40 years there is already the company Elro, which is active both in the areas Health and Pharmacy, as well as in the Energy industry and in Equipment construction.

Although one knows primarily the large plants, which are for example in the industry of relevance, the Elro GmbH scores at the same time by their high-quality offer, if it concerns fire protection and security technologies.

Internet vs. specialized trade: Where to buy my CO detector?

Often many consumers ask the question, where to buy best a CO detector.

The retail offers quite promising solutions in the context. Thus classical CO detectors can already be found in the discounter as well as in the supermarket around the corner.

But as it turns out again and again, it is precisely the cheap models, that often either give up after short time the mind or are characterized by their striking unreliability.

Therefore it is absolutely worthwhile to go in local retail on the search for a CO detector.

The problem is in this regard that specialty stores, have high-quality and high-performance CO detectors test winners to offer, not are available in everyone city.

In general, the variety of offers leaves much to be desired with regard to this product group if you are looking for fittingproducts in the retail local .

It's worth researching online

Surely there are in one or other city very well also specialty shops, where you can buy a CO detector. However, keep in mind that CO notifiers from local trade may be significantly more expensive than online purchase.

Here you should consider that the online providers usually use considerably more attractive conditions.

They have no limited storage space at their disposal, but they can buy far more large quantities, which ultimately has positive effects on price.

Generally, manufacturers, who not are tied to limited product presentation or storage capacities are retail clearly in advantage.

As the experience makes clear, the financial expenses for rent or lease, storage are very high.

This also leads to the fact that some retailers not seldom save at other corners, for example at the selection of staff. Just with regard to the purchase of a tested CO detector you should however not rely on specialist not specialised staff. Rather, it depends on view professionality and competence.

Using the benefits of the Internet

If you look around directly online, the selection in terms of CO detector is impressive large. For each use, for each claim and each budget the fitting device can be found.

The special thing is that you can online usually even save cash money. Because the savings, those the online offerer due to the favorable buying conditions has to offer, it can pass on directly also to the cost-conscious customer.

Conversely, it is similar: additional expenses are also passed on by retailers to their customers, at least proportionately.

For each device purchased, the customer therefore pays a few additional Euros in order to “finance” the fixed costs to a certain extent .

After the order of a tested CO detector in Internet the customer benefits, as the experience shows again and again. There are additional vouchers from the provider or from other dealers included in the package.

In this way he can also enjoy further discounts.

Things to Know & Advisor

The History of the CO Detector

Already in the past the people often had to do with unexplained deaths, which sometimes also resulted from the fact that their fireplaces, were mostly unsecured in the inside of the apartments. These “swallowed” literally the oxygen, so that the residents got the spaces ultimately breathing distress.

Often the resulting oxygen deficiency resulted in the death of humans. However, in the absence of technical device long not it was clear what the cause was for the deaths. Another critical aspect in the context is the frequent occurrence of fires.

In general the people in 17. to 19. century had to do with fires very often, whereas the wooden buildings were generally extremely “receptive” to sparks. Unfortunately, the technical circumstances at that time not were in a particularly good condition, so that the people mostly helplessly faced the catastrophic circumstances.

Only at the beginning of 19. century so-called heat detectors were developed, which emit a signal tone when measured to high temperatures in spatiality.

Alarm sensor to protect against CO and Co.

Basically the heat detectors belong to the classics among the signal transmitters, when it comes to recognizing dangers and averting them at the same time. A little later one recognized the hazard, which also came from the invisible CO. However, it was only several years later that it was possible to develop adequate warning devices.

Certainly the first devices were comparatively unreliable. However, since the tin dioxide is used as sensor source, the consumers generally benefit from a very safe and reliable functionality.

The devices, which are equipped with clear displays, offer in this view by the way further advantages, because in this way the interested consumer can also inform himself about the CO values in his living area.

Figures, data, facts about the CO detector

Only since the beginning of 19. century there are CO detectors, around the people from a life-threatening stress by carbon monoxide to protect. If you take a look at the market, you will notice that the acquisition costs for devices of this product category differ by a considerable measurements from each other.

Especially cheap devices are available in the discounter around the corner for example already for rund 5 Euro.

Here however Caution is required, because the Reliability and the Lifetime not is too well ordered.

Basically we recommend to invest at least 25 to 30 Euro for CO detectors, because experience has shown that the value and the functionality do not leave much to be desired for devices of this price class.

Precisely because safety plays such an elementary role, special EU norms have become established in the course of time, which must be fulfilled by manufacturers from CO detectors.

Assuming that their products do not fully scope meet requirements, there is no chance to market the corresponding products.

Do not bet on the first best offer: The numbers speak for themselves

Currently, CO detector is divided into three basic classifications.

The Class 1 is assigned to the devices whose use in rooms is possible with a height of up to 7.5 m.

Class 2 includes CO detectors, that can be used in rooms up to 6 meters height. CO detectors of class 3 are all those devices that are suitable for rooms with room height of up to 4.5 meters.

The average volume level of the alarm for modern devices is approximately 85 dB. The average lifetime is usually between five and ten years. It is also worth mentioning that own weight for most devices does not exceed 200 grams.

The typical size ratios for the devices currently available on the market are approximately 8 to 12 cm in length, 10 to 15 cm in the width and 2 to 6 cm in the height.

Trends in the CO detector range

The manufacturers of CO detectors are literally firing in the process of constantly developing new devices in order to ensure an increasingly comprehensive protection of consumers.

There are currently not only Brand- and Smoke detectors as well as CO detectors in the trend, which are characterized by their special Reliability and a high Functionality. Also especially popular are the CO detectors, which score points due to additional properties and features.

The Trend currently includes devices, which are equipped with a particularly large and clear LED display, on which you can read the respective CO load in the room as required.

The larger and betterilluminates the display, the more popular are currently apparently the corresponding devices.

In addition, the demanding consumer currently particularly likes to fall back on CO detectors, which are equipped with a mute button and a test button. These functions serve the better control of the CO detector. However, they also contribute to the fact that you can test the functionality occasionally.

If you consider that otherwise it is comparatively difficult to check the functionality in general, such test features are indeed suitable.

A wide range of functions

Many providers of CO detectors even go one step further.

If you want to go with the time, then you are well advised to choose a CO detector that measures not only the carbon monoxide content in the ambient air, but from the beginning on reporting systems, which besides CO also react to further hazardous gases.

Here, among others, the also hardly detectable gases propane, methane, city gas, butane and natural gas are to be mentioned. In view of the fact that there are still many households gas heaters and pipelines, the purchase of these trend-products is indeed appropriate.

In this way you go directly to Number safe and are optimal also protected against other Gases protected.

Legal framework conditions

The EU standard EN 50291 defines all relevant aspects with regard to characteristics and functionality of smoking- or CO detectors.

This means, among other things, that with a CO concentration of 50 ppm or 0.005 % an alarm trigger must occur within 60 to 90 minutes. If the CO concentration is 100 ppm or 0.01 %, the device must give within 10 to 40 minutes alarm.

With a CO concentration of 300 ppm or 0.03 % it is indispensable that the alarm is triggered within maximum three minutes according to default of the law.

Generally it is prescribed in more and more federal states that at least in public or at least commercially used spaces it is prescribed that CO detectors be installed. And preferably in every room, where audience is.

Always play it safe

An increased CO content in apartments or buildings can result from improper installed or maintained chimneys or chimneys. The house and flat owners are therefore obliged by law to require the chimney sweep at least once a year to inspect the building equipment equipment available.

If this happens not, under circumstances – depending on province – sensitive sanctions must be expected. In general it is of an almost vital relevance, that CO detectors, which are operated with batteries are tested in regular distances checked and tested for their functionality.

Moderne CO detectors have an integrated test button, which you can use to examine in detail, to what extent the sensor is set to a possibly present CO fraction in the ambient air jumps – or not.

In addition, it is generally stated with look at official guidelines, that a CO detector should be exchanged for a new one at least distance from 5 to 10 years. This is less due to the material characteristics of the corpus' than to the quality of the sensor.

Because the mode of operation of the integrated tin dioxide may change with time, which may affect the reliability of the device itself, it is essential to replace the CO detector with a new device within the specified period.


To appreciate the meaning of a CO notifier in full scope, the consumer should consider some facts around the development of fire, smoke and dangerous fumes. It is a fact, for example, that in Germany alone there are year for year in average, believe it or not 200,000 fires.

The number of deaths is about 600 and the number of fire casualties is with 6.000 people also alarmingly high. Not to be forgotten in this regard are the partly substantial long-term consequences, with which those affected have to struggle.

As a rule, genesis releases flames carbon monoxide even before flames is formed, whereby a few minutes are sufficient to release the life-threatening gas.

What many consumers also not are aware of is the fact that the cause of death at outbreak of a fire is by no means always the flames, but in most cases the smoking development already leads to death.

Scientific studies and analyses have shown that just once three breathes at one adult are sufficient to lose by inhalation of CO awareness. If you take ten breathing with carbon monoxide – most of the time you don't even notice it in addition – this can cause death.

The noise level, that a modern CO detector emits in the case of a too high concentration of CO is numbered average with round 85 dB.

The acquisition costs for a functional and especially long-lived detector are approximately 25 to 30 Euro. Devices in the low price category sometimes have to expect function losses after a relatively short time under circumstances.

Who decides for a particularly high-priced device, profits beside a reliable function mode in addition from a particularly easy handling, a very stable construction and a particularly clear conception of the display. This makes it easier to determine the CO values in between.

Correct installation

It should be noted that CO measuring instruments are generally divided into three basic categories. This Classification should already help you to find out where which device will be hung in the Anterior field. So CO detectors the class 1 are designed for especially high, large-area rooms with a room height of up to 7.5 m.

CO detectors of class 2 belong in rooms with a maximum room height of 6 meters, whereas CO detectors of class 3 are created for rooms with a height of up to 4.5 meters. In general, you should hang the CO detector as described in the assembly instructions.

Most devices are fixed to the ceiling of room, ideally in the middle range of ceiling.

In any case, the installation of a detector device within up to two meters of an extractor hood must be avoided, as otherwise the values could change drastically and this could result in false alarms.

The frequent a false alarm is triggered, the unreliable appears a CO detector, so that at the end you may even not pay more attention to the signals. Until it's possibly too late.

Do not hang up here

It is also important not to mount the CO detector where windows and doors are near. Due to the penetration of fresh air from outside, a possibly too high CO concentration in the room could only be detected much too late.

Assuming that it is generally very warm or very cold in a certain area, you are well advised to hang up the CO detector preferably not.

It is a fact that also strong climatic fluctuations under circumstances could falsify the existing CO values.

In addition, you should avoid hanging the CO detectors in damp rooms, wet cells or showers or bathrooms. Also the humidity air could possibly trigger one or the other wrong alarm.

In itself, the assembly of a CO detector is no particularly difficult task. In the scope of supply of each device a assembly instructions is available which you best step go through for step.

However, when battery-powered detectors are used, make sure to insert the batteries before attaching to the ceiling or wall.

In general, make sure that no disturbing objects are present in the close of the CO detector. Also consider that if possible there should be a CO detector in every room.

It is also a fact that the performance of such a alarm never reaches over several floors, but that in everyone floor you should mount the appropriate number of pieces to sensors .

Useful accessories

The accessories portfolio of each CO detector usually contains additional batteries if it is a high-value product. However, it is possible that these not are always completely full, but that they sometimes give up after short timethe spirit“.

Generally, supplied batteries different products shows again and again that the qualitative characteristics of batteries leaves much to be desired. Therefore it is worthwhile to check the replacement batteries if possible at short intervals – after insertion into the device – for their functionality. alternative we generally recommend the separate purchase matching batteries.

Further practical accessories are small tools, which make the assembly of the CO detector to the ceiling or to the wall as simple as possible. This includes screws or other device. Also, the additional acquisition of screwdriver or key may be very helpful for this purpose.

Sometimes it turns out after delivery of the device that none manual is present. This can – depending on provider – be downloaded and printed directly from the homepage of the producer.

If this possibility is not given, you can, usually via a freephone number, record with the support of the company contact, in order to inquire in this way the delivery of the required assembly- or operating instructions.

Alternatives to CO detector

If none CO messager is currently available, but if you still want to be on number safe, then purchase a heat detector very recommendable. Such a device reacts especially if the temperatures in a spatiality are unusually high.

The usual temperatures in habitable areas are approximately 20 to 22 degree Celsius. However, if 40 or 50 degree prevail, such as before the outbreak of a fire, the heat detector alarm.

Depending on device the signal temperature can be set individually. It is worth knowing that the heat detectors in especially humidity rooms, as for example in bathrooms not always convince by a reliable functionality.

A fire detector is always an extremely meaningful purchase. When you consider that a majority of fire victims is surprised at night in sleep by fire, it is indeed sensible to be in possession of a detector that states the outbreak of the fire on time.

Unlike the fire detector, the smoke detector already emits signals when no flames have arisen, but it “reports” already alarm, when only a smoking development was perceived.

This means that the inhabitants of the rooms are put into alarm standby earlier and thus have better possibilities for escape.

The development of smoke is already associated with a considerable carbon monoxide development. If this not is detected in time, it can indeed have serious consequences consequences.

Meanwhile, CO detectors are already able to detect not only CO, but also other life-threatening gases.

If butane, natural gas, propane, methane or similar escape at a certain point in the living area, these practical helpers immediately emit a signal tone.

In this respect, these flexible devices are by far better solution, when it comes to timely detection of gases in housing.

Questions and Answers on CO Detectors

Where do I put a CO detector?

If you heat your home with gas, for example, a CO detector is almost an absolute must and should be installed in the individual rooms. The appropriate place for such a detector depends on what type of gas it is.
