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.
