6.2.1 Function test
If you have installed the smoke alarm successfully you have to perform a
function test rst. It is also recommended to perform a function test once
a month after installation to ensure correct operation of the device.
The loud warning sound may damage your hearing. Protect
your hearing during the function test.
To perform the function test, proceed as follows:
• Press the operating button of the smoke alarm.
• If the alarm sound is triggered 3 times, the LED ashes red and the
escape light ashes during the function test, the smoke alarm is work-
ing correctly.
• If no alarm sound is triggered or no visual signal can be detected, the
device is defective and has to be replaced.
After the functional test, the smoke detection is deactivated for 10 min.
During this time, no alarm can be triggered.
