Smoke signals

A smoke detector belongs in every household good, so I have learned. At least the dormitories should definitely be backed up because it is a risk not perceive time in his sleep, just where the danger is in sleep significantly larger by fumes as the flames by. Also escape spaces (corridors) should be covered. Ideally, all rooms except the bathroom and kitchen.

This smoke detector has a built-in lithium-ion battery, which is designed for 10 years standby mode and can not be changed. The installation is quite simple: An annular plastic support is fixed with two screws and plugs on the ceiling. A switch on the bottom serves as a test button and a circuit breaker in false alarms.

The smoke detector is activated by the way only with screwing in the holder, for a switch mounted on the surface provides. The test I conducted with an extinguished candle; Smokers have it naturally easier. The noise that the device developed in the event of an alarm (indicated 85dB) should be sufficient to tear even heavy sleepers from their dreams.

For detailed information, also the behavior in case of fire, can be found in the accompanying unfortunately only in English instructions.
