General
Smoke alarms sound their alarm horn when they detect smoke. Everything preventing the smoke from reaching the alarm obstructs an early alarm.
A single smoke detector provides only limited security. Fire in another room will only be detected after smoke reaches the alarm. It is therefore recommended to install a smoke alarm on every level of the home if not in every room.

Product characteristics
Photoelectric effect
This recently developed photoelectric sensor-camber is insensitive to interfering influences. Every device is separately calibrated in order to avoid false alarms due to, e. G., cigarette smoke. The power supply is electronically regulated, thereby maintaining a constant sensitivity of the alarm.
Battery operation
The functioning of the detector is maintained even in case of a power failure. On an average the battery's (standard 9V battery) service life is 1 year.
Signal lamp (LED)
A flashing small light (every 43s) signalises a failure-free operation.
Fully automatic test function
Advanced electronics ensure the best possible operating readiness by means of an automatic self-test function.
Battery warning function
By means of a warning sound repeated every 43 seconds (for up to one month), the smoke detector signalises that the power supply of the battery is insufficient and it needs to be replaced.
Control button
Temporarily increases the detector's sensitivity to test the alarm function.
Noisy (85 dBA) piezoelectric warning sound
Vibrant warning sound in case of fire alarm - high efficiency
This device does not contain any radioactive substances!
Function
Smoke caused by fire is very dangerous, especially because of today's widespread use of synthetic materials in modern homes that might generate poisonous vapours when burning.
The smoke alarm detects smoke caused by smouldering at an early stage and warns by means of a loud, vibrant sound, thereby waking inhabitants up at a point of time when a safe escape is still possible.
The smoke alarm operates according to the scattered light principle. A light source and a photocell are arranged so as to ensure that normally no light strikes the photocell. The light source is activated in short intervals.
If the concentration of smoke particles in the enclosure reaches a certain level, the light is reflected and reaches the photocell. This will set off a loud fire alarm.
