The photoelectric smoke detector has a replaceable lithium long-life battery that lasts for 10 years. When the battery power becomes low, this smoke detector will give an early warning.

In addition, this smoke detector has an LED light that lights up briefly when the smoke detector is in operation. It also has a TEST button to check the detector in advance.

Guide: Questions to consider before buying a smoke alarm

What are the legal regulations and recommendations (smoke detector obligation)?

In the meantime, smoke alarms are mandatory in all 16 federal states. In the respective state building regulations, it is uniformly prescribed that all bedrooms, children’s rooms and corridors must have a smoke alarm.

This is also regulated in the DIN 14676 standard. In addition, there are further provisions here regarding where and how, for example in the event that the rooms have a certain shape or subdivision.

The smoke detector obligation applies not only to landlords, but also to you as the owner of your private property. Which duties you might have as a tenant, we will answer in general. The regulations of the individual federal states can be easily viewed on the Internet, for example at Rauchmelderpflicht.eu.

Why are smoke detectors so important?

Dangers of a house fire seem to be much less today and you also take care that no danger is created.
However, there are situations where even the slightest source of ignition can quickly cause a fire that you may not even notice. If you sleep while smoking, this is actually very dangerous because you won’t notice it for a while.
Smoke alarms are life-savers because they can inform you when there is a small amount of critical smoke and you can get to safety in time.

Although smoke alarms cannot prevent a fire, they can at least ensure that people are warned in time and are rescued.
There are reports of fire brigade operations from all over Germany which prove that people have been woken up, neighbours warned or major damage prevented by the alarm of a smoke detector.

What do I have to consider regarding quality standards?

Since the reliable functioning of a smoke alarm is of fundamental importance for your safety, you should actually buy a higher quality product from a specialist retailer rather than a cheap smoke alarm like the ones you can buy in DIY stores. It is also very important that you check the quality seals and logos: CE, EN 14604, Q and VdS.
The CE mark and the EN 14604 specification are important, but this only means that the product may be sold in accordance with European standards. Nothing is said here about the quality of the device.
The DIN 14604 standard stipulates that a minimum volume of 85 dB and a low battery indicator must be provided. In addition, the battery must have a service life of at least one year and the possibility of functional testing.
In order to acquire a really reliable smoke alarm detector that has been tested according to quality standards, please also check whether the suffix VdS (VdS Schadenverhütung) is available. Sometimes you can also find the logo of another independent test centre, namely Kriwan. Both companies test the quality and safety of smoke detectors.
Another important quality feature is the symbol Q. This indicates that the smoke detectors are particularly reliable and durable. The batteries are also tested. This gives you additional security regarding their running time.

What do I have to consider for different living situations?

The different cases are numerous, which is why we would like to recommend you to follow the application standard DIN 14676. You can get an insight for example at Rauchmelder-Lebensretter.de

Did you know that fires kill about 400 people a year in Germany?
Only 5% of them die from the flames of the fire. The remaining 95% suffocate from the poisonous fumes that are produced by a fire. In addition, a large number of fire survivors suffer long-term delayed effects. In total, the statistics in Germany count about 4000 burn victims with long-term consequences per year.

How long does a smoke detector last?

Most smoke detectors and their batteries last ten years. However, there are also smoke detectors with a lifetime of five years. Alkaline batteries only last one to two years, however.
Please keep an eye on when you put the smoke detector into operation. Within the functional life of years, the smoke chamber will gather dust, but it is also fitted with a plastic sieve to prevent it from getting dirty too quickly. However, high-quality smoke alarms also offer pollution compensation.
In addition, all smoke detectors have an LED indicator lamp to show that they are working properly. It flashes at regular intervals, usually every minute.

Which batteries are recommended?

There are lithium and alkaline batteries. The latter only last for 1 or 2 years. Lithium batteries are a little more expensive, but they also last 10 years. In the long run this is even the cheaper option.
Make sure which batteries suit your smoke detector. You can find out which ones are suitable for your smoke detector by referring to the operating instructions or the embossing on the battery compartment when you need to replace the batteries. By the way, the smoke detector emits a warning tone when the battery power decreases.
However, smoke detectors are also available with built-in lithium batteries, which really do last 10 years. The costs for this are of course higher, but many private individuals are already making increasing use of this variant.

What does a good smoke detector cost?

Smoke alarms are available in very different price ranges, which can vary from 5 to well over 100 euros. But: The most expensive model is not always the best, as Stiftung Warentest found out.
You should not consider models for 5 euros from the DIY store. Good models with alkaline batteries can be bought for as little as 10 euros.
With WLAN smoke detectors, you should be aware that some smarthome systems cost over 200 euros, but often come with smoke detectors. The gateway as an alternative even costs about 400 Euro.

Where can I buy good smoke detectors?

For your own safety, it is better not to consider the very cheap models from the DIY store or various supermarkets, but to consult a specialist dealer. The fire brigade or chimney sweeps will also be happy to give you tips on where to get a good quality smoke detector.
Usually you will find the best selection of smoke detectors on more or less specialized online sales sites, the well-known online shopping companies or in electronics stores. Here is a small list that our research has revealed:

Decision: What types of smoke detectors are there and which one is right for you?

There are numerous types of smoke detectors, some of which have different applications and functions:

  • Photo-optical smoke detector
  • Heat detector/heat detector
  • Thermo-optical smoke detector
  • Wireless smoke detector
  • WLAN smoke detector
  • Ionisation smoke detector
  • Flue gas detector
  • Smoke detector for the hearing impaired

Here we want to introduce you to the various smoke detectors with their functions and give you an overview of which ones are suitable for your needs.

How does the photo-optical smoke detector work?

Photo-optical smoke detectors are most common for general smoke warning. In general, the principle of the photo-optical smoke detector is that it contains a smoke chamber that takes in room air via lateral openings and checks smoke particles via light signals.

Incidentally, larger particles such as insects cannot penetrate through the openings with good smoke detectors. The transmitter (infrared diode) regularly emits light signals, but the receiver (photodiode) only receives them in the event of larger smoke development.

If there is a large amount of smoke particles, the infrared beam breaks and is directed to the receiver, the photo sensor. The sensor transmits the signal to a processor, which checks and correlates it to […]

How does a heat detector work and what is it suitable for?

A heat detector is not based on the development of smoke, but on the exceeding of a certain room temperature, usually 60 degrees. There are also heat detectors that measure an unusually rapid rise in temperature.

This makes a heat detector ideal for your kitchen, bathroom or workshop, because unlike a smoke detector you can install it in rooms where smoke, dust or water vapour is generated.

How does a thermo-optical smoke detector work and what are its advantages and disadvantages?

With a thermo-optical smoke detector, the checking of smoke particles is combined with the checking of the room temperature.

Conventional photo-optical smoke detectors without contamination compensation are criticized for triggering false alarms too often. They also react to too much dust and cooking steam.

Advantages

Reduced number of false alarms
Also suitable for bathroom, kitchen and workshop
Suitable for living areas close to steam generation

Disadvantages

Combination unnecessary for living spaces

The thermo-optical smoke detector strikes when both a dangerous amount of smoke particles is detected and the room temperature exceeds 60 degrees. This function is useful in rooms with steam and dust where an optical smoke detector would trigger false alarms.

The disadvantage is that the thermo-optical smoke detector does not make sense for normal living spaces, as it also sounds the alarm when the measuring factor smoke is exceeded and the measuring factor heat only comes into play much later.

How does a wireless smoke detector work and what is it suitable for?

If you live in a large house or apartment, we recommend smoke alarms that can be networked via radio. The function of the wireless smoke detector corresponds to that of the photo-optical smoke detector.

The wireless smoke detector located in the room where a fire breaks out sends a warning signal to all other detectors in the building. In this way, you will also be informed about dangers in rooms that are beyond your hearing range.

You should check distances and obstacles in advance to determine whether you need a repeater. Also make sure that the radio module is included. Otherwise you would have to retrofit the module.

How does a WLAN smoke detector work and what are its advantages and disadvantages?

The WLAN smoke detector is networked via WLAN instead of radio, as the name suggests. You can also check the smoke detector via an app. It also works like the photo-optical smoke detector. However, it is mostly used in conjunction with a smarthome system.

Once you have mounted the smoke detector on the wall, you can install it quickly and easily. You connect the smoke detector to the Smarthome control centre and then to your WLAN router

You can easily check the maintenance status and the battery function via an app, so you can also check it while on the road. If there is a danger or a problem, for example a low battery level, you will be informed via SMS.

You can also integrate the smoke detector into a smarthome installation. In case of fire, for example, the lights would be switched on or the windows opened. Of course, the smoke detector must also work when the WLAN is switched off. You also need WLAN in the whole house and of course a Smarthome system.

However, there is also the possibility of buying a gateway for a wireless smoke detector, which is very expensive. The gateway connects the wireless smoke detector to the Internet.

How does an ionisation smoke detector work and what are the advantages and disadvantages?

The ionisation smoke detector reacts to even a small amount of smoke particles. However, it works with radioactive radiation and is not recommended for private use.

Two electrodes under DC voltage make the air between them conductive. If smoke particles are attached to the air molecules, the smoke detector sounds the alarm.

The advantage may be the fast reaction, the disadvantage is clearly the radioactive radiation. Today ionisation smoke detectors are obsolete. Our research has shown that they are not even offered in online specialist shops for private individuals.

How does a smoke detector work and what is it suitable for?

The smoke detector (also called fire gas detector or CO detector) is well suited for dusty rooms where the optical smoke detectors would sound the alarm.

The flue gas detector measures the concentration of carbon monoxide (CO) or carbon dioxide (CO2). It is optimal and also very important for rooms where you heat with a stove (for example a gas or coal stove) or a fireplace. The concentration of carbon monoxide can quickly become life-threatening, especially in small, enclosed spaces, because the development goes unnoticed.

Flue gas detectors are mostly used in industry. Here you must observe the EN-50291 standard when buying and installing.

The following table shows you the symptoms of carbon monoxide poisoning:

How does a smoke detector for the hearing impaired work?

Smoke alarms for the deaf or hearing impaired use an optical signal instead of an acoustic one, which is often also transmitted to a vibration pad.

The smoke detector is connected by radio to a light system that emits strong flashes of light in the event of an alarm, which are also perceived during sleep. The vibration pad is actually a pad that you can put under your pillow or carry in your trouser pocket.

Smoke detectors for the hearing impaired are very expensive. For a two-room apartment you would have to invest amounts of 300 to 400 euros, for a house or larger apartment up to 1000 euros. However, the costs are covered by the health insurance companies.

Purchase criteria: You can compare and evaluate smoke detectors based on these factors

In the following we would like to help you with your purchase decision and show you criteria that you can use to compare which smoke detector would be suitable for you and your needs, with some factors being less important than others.

The main criteria are summarised below:

  • Weight
  • Dimensions
  • Battery type / battery life
  • Smoke detection area
  • Montage
  • Alarm volume
  • Test function
  • Mute
  • Display of operational readiness
  • Colour
  • Quality seal/certification
  • Networking

Below you can read what the individual purchase criteria mean and what is important in this regard. Whether optical smoke detector, thermo-optical smoke detector, heat detector or smoke gas detector – the relevant purchase criteria are identical for all of them.

Weight

The flyweight of a smoke detector is not an important purchase criterion. Of course, every blanket can withstand it. The mounting options including adhesive mounting are also designed for the weight of a smoke detector.

All smoke detectors that have been researched include appropriate installation options, as described in the purchase criterion Installation.

We will still include this criterion if you have any doubts and because other product sites also provide this information.

Dimensions

The focus of a smoke detector should be on its functions. However, there are also smaller smoke detectors for a more pleasant appearance if you need to install a smoke detector in a small room.

Smoke detectors of normal size may have dimensions that deviate to a greater extent. The length is between 19 and 10 centimetres, the width between 10 and 5 centimetres. So here you can check which devices you might like optically, although this should not be one of the main purchase criteria.

If for various optical reasons a regular size smoke detector should bother you, we recommend a mini smoke detector. Depending on the manufacturer, it can also be called a design smoke detector. These small smoke detectors with their 4 centimetres length and width each are hardly noticeable and therefore almost invisible.

However, you don’t have to worry that you’ll have to make sacrifices in functionality or quality of features because of the mini-format. It also covers the same area as a normal-sized smoke detector.

Battery type / battery life

If you want to avoid wasting more time and effort and also save costs and protect the environment, we recommend smoke detectors with lithium batteries.

There are smoke detectors with alkaline batteries, but they only last up to 3 years. These are also quality smoke detectors, but most smoke detectors contain a powerful lithium battery, either replaceable or built-in, which will last 10 years.

In the case of a smoke detector with a permanently integrated lithium battery, this naturally means that you will have to replace the device after 10 years. However, due to the degree of soiling of the sensor system, these devices should be replaced after 10 years anyway.

Good smoke detectors with integrated lithium batteries are already available for 20 to 30 euros, which is why replacing them is cheaper than replacing alkaline batteries every two to three years.

Smoke detection area

The smoke detection range is a factor you may want to consider, especially in large rooms or long hallways.

Some manufacturers or product pages unfortunately do not specify the smoke detection area, but it is usually between 40 and 60 m². This could be important for rooms larger than 60 m² or longer corridors, because in the latter case you also have to observe the provisions of the application standard DIN 14676. This standard prescribes several smoke detectors at certain intervals.

You should also check the range of radio smoke detectors. These are useful if you have a very large apartment or a house with several floors.

Montage

Depending on your crafting talents, the type of assembly could be a relevant purchase criterion.

The researched smoke alarms come with mounting accessories and instructions. Most of them even offer optional mounting via a mounting plate with screws and dowels or adhesive mounting using a magnetic or adhesive pad.

If a smoke detector, whose functions and quality convince you, only offers an installation possibility where drilling is necessary, you can also buy an adhesive fastening or a magnetic disc additionally. For the latter, our research has shown that the Magnetolink mounting set has proved to be the best choice.

These magnetic discs can withstand 10 to 50 kilos, which should not be a problem for such a light smoke detector. Furthermore, the installation is very easy and the magnetic pad holds on almost all surfaces.

Of course, screw mounting is safer and you don’t have to worry that the smoke detector might fall down. This would be very annoying with a more expensive device such as a wireless smoke detector. Furthermore, the use of magnetic or adhesive pads could invalidate the certification. Therefore, it is better to use the manufacturer’s accessories or ask them if you want to use some of these adhesive pads yourself.

Alarm volume

The alarm volume is identical for all smoke detectors certified in accordance with the DIN 14604 device standard at 85 decibels within 3 metres of earshot. So if you buy a certified quality smoke detector, you can assume that the volume follows an important guide value.

This means that you should definitely look for smoke detectors with this standardized volume if you are considering a much cheaper smoke detector. It is an important criterion for your safety.

A few smoke alarms have a volume level of 88 decibels. In general, the volume should not be a problem unless the smoke detector frequently triggers a false alarm, which should normally happen very rarely with quality smoke detectors. In addition, false alarms can be switched off quickly.

Test function

Since you should service the smoke detector annually or check its functionality, it is extremely practical if the smoke detector is equipped with a test button.

When you press the button, you will hear a beep, which you can use to determine whether your smoke detector is operational. This function is also particularly useful if there is no status LED or it is switched off. Otherwise, it would be quite cumbersome to determine during the annual inspection whether the smoke detector is still working.

All good smoke detectors are now equipped with this test button, so this is not a criterion that requires a long search. If this is not the case, the smoke detector can also be tested with a special test spray.

Mute

In the event of a false alarm or a warning alarm indicating that the battery is low, it can be of great advantage to be able to press a mute button until the source of the error is found.

The mute button can be operated using a broom handle. False alarms can be triggered, for example, by a large accumulation of dust particles in the smoke detector, because the smoke detector does not contain pollution compensation.

Another reason could be a large amount of water vapour escaping from the bathroom or kitchen into the adjacent room where the smoke detector is installed. It could also be that false alarms are triggered when you operate a stove, for example a charcoal oven.

Not only noise-sensitive people are then extremely stressed by a shrill alarm tone that cannot be turned off, especially if it lasts for a long time and you might be torn from sleep in the middle of the night.

The mute button, which all good smoke detectors also offer, switches the alarm off for a few minutes – about 4 to 10 minutes. If the reason for triggering the alarm still exists, the alarm will be triggered again. If for some reason the alarm sounds frequently, the mute button is a useful feature.

However, due to frequent false alarms, smoke detectors should not be installed in the bathroom or kitchen. Heat detectors or thermo-optical smoke detectors are available for this purpose. The latter combine the measurement of smoke development with the measurement of temperature.

Many of these smoke detectors have already been improved so that they do not only sound the alarm when both factors exceed measured values. With regard to the stove, we recommend a smoke detector, also called a carbon monoxide alarm.

Display of operational readiness (LED)

Although visual confirmation of functional readiness is an important criterion for checking, it can quickly become disruptive in bedrooms. Here you could consider a device without display or alternatively with bedroom function.

There are actually already some smoke alarms that no longer integrate a function display. You may want to press the test button more often to ensure that your smoke detector is working properly.

Alternatively, some manufacturers offer the bedroom function, which is used to dim the flashing light in a specified period of time, for example from 10pm to 6am.

Colour

You have a wooden ceiling or a ceiling painted in colour and therefore a white smoke detector disturbs you for optical reasons? There are options here too.

However, few manufacturers offer coloured designer smoke detectors. Most are actually white or in white tones. If a manufacturer offers several colours, you don’t have to worry about investing more in the optics.

By the way, you should not paint a smoke detector. The vents could get clogged.

Quality seal/certification

In order to obtain optimum protection and reliability in function, you should pay attention to the quality features and certification according to the device standard DIN 147604 when purchasing.

The naming of the standard does not imply anything about the quality of the device. You can ensure this when you see the logo of VdS or Kriwan. These are two independent test centres that check smoke detectors for quality standards. Furthermore, the symbol “Q” indicates increased reliability and longevity, as their batteries are also checked.

If you find all these seals and logos, you can be sure that you are buying a high quality, reliable and safe smoke detector. And that should be worth your security. Besides, such smoke detectors are already available for a low price.

Networking

In the case of a spacious apartment or a house with several floors, wireless smoke detectors or WLAN smoke detectors for the Smarthome system are recommended for networking. If one smoke detector triggers an alarm, all other smoke detectors are also notified.

With wireless smoke detectors, you should note that you must purchase the corresponding wireless module for each device. The WLAN smoke detectors naturally require an already existing smarthome system. But then they can be controlled via an app.

The smoke detectors should be able to work even without power supply and also when the WLAN is switched off. However, a WLAN connection must still be available throughout the house for networking.

Trivia: Worth knowing facts about smoke alarms

What is the difference between a smoke detector, a smoke alarm and a fire detector?

There is no difference in language use between a smoke detector and a smoke alarm. They are synonyms, whereby the term “smoke detector” is used more frequently. However, a fire detector has a completely different area of application.

The term smoke detector is actually not correct, because it is actually part of a fire alarm system that only relays but does not trigger an alarm. Nevertheless you will find this designation very often. That is why we use it here often.

When doing research, it seems to be the case at first that the terms smoke detector and fire detector are often used synonymously. You may have already come across this in your search. In general, it is about devices that sound the alarm in case of fire and the resulting smoke development.

However, these devices differ in their field of application. A smoke alarm is used in the private sector, while a fire alarm is mostly used in public buildings and is part of a fire alarm system. This also means that the system informs the fire brigade, which is not the case with a smoke detector!

How and where is a smoke detector installed and what do I have to consider during installation?

Smoke alarms must always be mounted on the ceiling. Please also make sure that you place them in the middle of the room if possible and that you keep a distance of at least 50 cm to lamps, cupboards or other objects or obstacles present!

It is also important that if you have a room of more than 60 square metres, you must install additional smoke detectors. Also be careful not to install the smoke detector in a draughty environment – i.e. not near air conditioning or ventilation systems.

The mounting material such as screws or dowels is included. In addition, many smoke detectors are also supplied with installation and operating instructions. Of course you would need tools such as a drill, although there are also installation options where adhesive or magnetic discs can be used.

What to do if the roof is sloping?

Since the smoke moves upwards, you should always mount the smoke detector on a horizontal surface. If the roof is too pointed, help yourself with a plate.

It is basically no problem if you install the smoke detector yourself, but please note any further conditions imposed by your insurance company regarding liability. You may have to hire a specialist. For further installation suggestions and assistance and regulations please consult the application standard DIN 14676.

How do I check the functioning of a smoke detector and how often must it be checked?

The smoke detector must be checked at least once a year for proper functioning in accordance with the smoke detector obligation. You can also do this yourself and follow the operating instructions for your device.

For example, the test can easily be performed by pressing the test button, which should trigger an alarm if it works correctly. If this is not available, you can also check the function at any time by using a test spray. This simulates smoke development. For this purpose you spray into the smoke chamber.

Furthermore, it should be checked whether the openings for smoke entry are free or whether there is any other damage. Higher priced units also indicate this automatically.

What do I do in case of a false alarm of the smoke detector?

A false alarm normally does not cause major problems and should not occur often.

Some smoke alarms have a mute button to stop the false alarm for a few minutes. This gives you time to eliminate the cause. Airing the place out might be helpful. Alternatively, you can use a broom handle to press the large mute button.

What can I do if the LED lamp bothers me?

If you are afraid that the LED indicator light in the bedroom might bother you, there are also good solutions for this.

You might consider a smoke alarm with a bedroom feature. Within a set period of time the LED light is dimmed. Alternatively, there are smoke alarms without function test display.

How does a smoke detector react to cigarette smoke?

A legitimate question in smoking households. But there is no reason for concern. A false alarm cannot usually be triggered by normal cigarette smoke.

But one should also not blow the cigarette smoke directly towards the smoke alarm. If there are a lot of smokers present, you should ventilate from time to time to avoid a false alarm.

Who is responsible in an apartment building for complying with the smoke detector obligation, installation and maintenance and who bears the costs?

In all federal states except Mecklenburg-Western Pomerania, the landlord is responsible for installing the smoke alarm.

In addition, in most federal states, the landlord is also responsible for the maintenance of the smoke detector and is therefore also liable in the event of fire if he has not fulfilled his obligation to check it. Therefore, it is often the case here that radio smoke detectors are installed which are checked from outside.

However, in some states, the landlord can transfer the duty of maintenance, including battery replacement and inspection, to the tenant or include it in the service charges if you as the tenant do not have to do the maintenance yourself.

In Mecklenburg-Western Pomerania, the tenant is also responsible for procurement and assembly. So please find out if this is the case for you, if you have not yet been informed about this.

Does the insurance pay in case of fire?

It is important that you are informed about the legal regulations.

In the event of a claim, it is possible that the insurance company will not pay if you have not correctly observed the regulations, even unknowingly. Uninformedness is considered gross negligence by an insurance company.
