3. Maintenance
In some German federal states, the owner of houses and flats are responsible for the
installation and functioning of smoke alarms according to LBO (State construction
laws) (see www.rauchmelder-lebensretter.de). Maintenance has to be conducted at
least annually and, according to DIN 14676 includes a visual inspection, a function test
and, if required, a battery change. A function test also has to be conducted after any
longer absence, at ,after 1 year at the latest.
The used battery and the device must be disposed of correctly so that
valuable resources may be recycled. Neither the battery nor the device
may be disposed of together with domestic or company waste.
3.1. Function test
BEWARE!
Danger of hearing damage!
During the function test (pressing on the light transmission bar),
a loud, shrill tone is sounded (at least 85 dB).
• Keep a minimum distance of 50 cm between smoke alarm and ear.
1. Conducting a visual inspection:
Check:
• Is the device found at the expected position?
• Are the smoke entry openings clean? - Remove dust if necessary. The device
must not be painted over.
• Is the device free from mechanical damage? - Replace the device if it is
damaged.
2. Conducting a function test:
If the function test is successful, a signal tone sounds. The smoke alarm works proper-
ly. If there is no signal tone, the device is not functioning. In this case, replace the bat-
tery and conduct the function test again. If there is still no signal tone, the device is de-
fect and must be replaced.
Smoke alarms must be replaced with new devices after a maximum
period of 10 years according to DIN 14604.
