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.
