Smoke Detector Guide - To save lives

The worst nightmare of a human. It burns in your own home and you do not notice it in time to save yourself and the family. To protect life and limb, smoke detectors have been developed. In case of emergency, they reach a volume of over 80 decibels to reach every ear. From a noise level of 80 dB, everyone demonstrably gets excited and immediately understands the situation as an emergency.

Most common causes of fire - save smoke detectors

The biggest hazards For humans and animals, fire, water and natural disasters become reality. By the way, tangible assets are also endangered, which affects the existence in bad cases. Billions of euros are paid year by year by insurance companies to regulate damage. Unfortunately, dead people can not find a way to bring the world back to life.

The majority of the population probably thinks that general inattention would be responsible for most fires. Statistics on fire causes show something different! In approximately 35 percent Of the cases, the causes in the field of electricity can be found. Just 17 percent are attributed to human error. The best known example is probably the cigarette in bed. Just 3 percent accounted for candles, which caused a fire.

If you look at the Statistics as regards the Electricity on, apply Dryer as the main cause. Close behind are television sets and refrigerators and freezers. Washing machines and dishwashers are at 6 percent sources of fire. All these devices can be found in every home and are virtually standard in our households. How should one avoid fires at all? Do we have to go back to the washboard and scrub the laundry clean? Click also through our Tumble dryer comparisonHere we give important advice.

Who comes across supposed bargains from abroad, should first the Verifier flag check. The German GS mark for example, stands for tested safety. It is a voluntary seal, which certifies a preliminary examination. It is trustworthy and stands for safe use. Electrical appliances with VDE mark certify compliance with the highest safety standards and are just as reliable.

Often, the cheap devices are installed inferior and there is a risk to mutate the number one cause of fire. Fairy lights, sockets, kettles and other small appliances should always be checked for safety. Insignificant loose contacts or faulty insulation can cause unaffordable damage and cost lives in an emergency. Incidentally, you will find more about high-quality socket strips in the large version Power strip comparison.

Smoke detectors are required

The smoke detectors regulates each state individually in its state building regulation. All regulations are the same in at least the following respects:

• At least one smoke detector must be installed in each bedroom, nursery and hallway. The corridors departing from these rooms are considered as escape routes and must therefore be equipped as well.

What differs depending on the state, are maintenance obligations and by whom they must be made. The following table is for your overview (as of January / 2016)

How do smoke detectors work?

They are perfect for the simple retrofitting from sleeping and living rooms suitable, not really expensive and in addition small and inconspicuous. But how do the small message units actually work and which ones? Differences is there? Basically, there are three types:

1. Photo-optical smoke detector
2. Thermo-optical smoke detector
3. Ionisation

This sounds like advanced physics, but is explained in a few sentences. The photo-optical Variants, are also called photo-electric designated. One means one and the same. This species is common and is integrated in popular models. In the small smoke chamber, a diode is used, which emits an infrared light. If there are smoke particles in the chamber, their light is broken. The scattered light is detected by integrated sensors and the smoke detector signals alarm. This technology is recommended because of the rapid response in the home.

Thermo-optical smoke detector also detect smoke concentrations and also record an increased ambient temperature. They work like the former, but also have a thermistor. A rapidly rising room temperature heats the thermistor. In total, two are installed. The measuring heat conductor and the comparative heat conductor. The former detects the temperature rise and the latter serves as a reference. If a rapidly rising temperature is detected during the measuring process, the smoke alarm sounds an alarm. These models are not suitable for private households, as they react too slowly.

Ionisation are considered to be particularly sensitive and fast reacting. A radioactive element is located between two metal plates and emits alpha and beta rays. It develops its own current flow, which is interrupted by any smoke particles. The result is the life-saving alarm. This variant is not widely used for a good reason. Although it is reliable and the radiation harmless, if the device remains closed. However, they are considered hazardous waste. If a fire occurs, the remains of the smoke detector would be in ruins. The radiation would now be free and would eventually pull all the debris with it as hazardous waste. We advise against it!

Minimum features for smoke detectors according to DIN EN 14604

A smoke detector needs some Criteria meet to get the certification. The criteria include, for example:

• An alarm volume of at least 85 dB (A)
• Recurring alarm already 30 days before battery end
• Test button on the detector
• Smoke must be able to penetrate into the test chamber from all sides

Smoke detector should carry the CE mark including the test number and have the suffix "EN 14604". More and more is also the Q-Label by highlighting some gadgets.

Networking technology of smoke detectors - radio networking

Wireless networking is worthwhile for very large residential units that are separated from one another by many walls. They are coupled with each other and are also based on battery operation. Just like all other smoke alarms, this way they are not dependent on the power grid. If a fire alarm detects a source of fire in the house, it forwards this information to the other devices. That way you get the vital information everywhere. The technique is simple. There is a master device (transmitter) and a slave device (receiver). Tech-savvy people in particular like to use radio transmission. It is recommended, as our smoke detector comparison showed, to use alarm units from the same manufacturer. This way, possible compatibility problems are eliminated. This method is reliable when properly installed, but also more expensive.

Install smoke detectors correctly

The Gland on the ceiling is the safest and generally recommended. Dowels and matching screws are usually included in the sets and make it easy for beginners. A short operating explanation is easy to understand and provided with illustrations. For those who do not want to, stand innovative bonding process is available for storage, management and analysis.

Tips for fixing in general:

• Always attach to the ceiling, as smoke rises
• Always in the center of the room and 50 cm away from the wall
• Always position horizontally, never put on the slope
• Never in wet rooms like bathrooms or kitchens due to steam
• Never install near air ducts or ducts

Take care when Fire detector comparison to the feature "installation" to make the right choice.

As well as large test procedures of the Stiftung Warentest show, the price is relative. The following points are essential in the purchase decision:

Stiftung Warentest smoke detector comparison

At the right time has the popular and reliable editors of Stiftung Warentest taken stock again. In the Output 01 / 2016 Twenty smoke detectors between 17 and 103 Euro were scrutinized to give clear recommendations for private households. It turned out to be a new thing that expensive is not equally good. Only ten smoke detectors have passed "good". The cheap one Egg Electronics Ei650 was also winner in the local smoke detector test winner and a high-priced competitor test loser. In any case: sure is safe!

Smoke detector not installed despite compulsory - what then?

The good thing in advance: as long as it does not burn, nothing happens! After all, nobody will control someone else's property. Such supervisory bodies are neither permitted nor intended.

But it should be the worst scenario, one Brand If the fire brigade and Co were forced to attend the circumstances, On the one hand, the potential source of fire must first be located. In the same breath, a fire fighter might ask for smoke detectors. And then?

In the home it becomes more or less considerable damage to property give, which underlie the fire. Your insurance may not want to settle these losses if it has been proven that no smoke detectors have been installed or missed this step.

However, it should be noted here that the smoke detection systems are installed exclusively to live to protect. Property damage is a completely different construction site and therefore this point always remains to be clarified by the lawyer in case of doubt.

The Gesamtverband der deutschen Versicherungswirtschaft eV, already commented on this issue. A missing smoke detector would have to be quasi cause for the fire, in order to lose claims. As a rule, however, such a connection can not be established. Normally, it would not ask any insurer for proof of incorporation or the like, since it was primarily about the life saved.

If it is rent property, the landlord is responsible for the smoke detection systems. If the duty had been neglected here, that would be bitter.
