Functional principle and features
Functional principle and features
•
The smoke alarm device does not detect gas, steam, heat or
fire/flames.
•
Persons with impaired hearing may not be able to hear the alarm.
Special alarms with 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 alarm is switched off as soon as the measurement chamber is free
of smoke.
