Functional principle and features

The smoke alarm device does not detect gas, steam, fire or flames.

People with impaired hearing may not be able to hear the alarm.
Alarms with additional optical signalling are available for such cases.

Particularly high electromagnetic radiation could impair the function
of the detector. For this reason, do not install the detector near
magnets or devices which produce electromagnetic radiation.

The smoke alarm device operates in accordance with the optical
principle (photoelectric reflection) and features a measurement
chamber in which infiltrating smoke particles are measured.

If the alarm threshold is exceeded, a loud acoustic alarm sounds.
The smoke alarm device also has a heat detector that triggers an
alarm if a threshold value is exceeded.

The alarm is switched off as soon as the measurement chamber is
free of smoke again and/or the temperature has fallen back to a
normal level.
