Test with a test gas
Before testing the detector, switch your alarm centre
to installer mode or omit the smoke detector. You
should check the smoke detector at least once a year
with the help of a test gas. The test gas simulates
smoke particles. This accessory allows you to test
whether your optical smoke detector works or not. If
the detector senses the gas, the LED light and the
siren reports an alarm. The alarm ends when the
test gas has dispersed. Following a successful test,
reintegrate the detector and exit installer mode.
Test button
The test button has two functions:
1. Test: Press the button and keep it pressed for 2
seconds. This checks the functioning of the siren.
2. Silence the detector siren: To switch off the detec-
tor siren, press the test button during an alarm. If
the detector chamber still contains smoke after a
few minutes, the siren sounds again.
LED
The LED shows the status of the radio smoke detec-
tor. It normally flashes every 35 seconds.
LED on: Smoke detected.
Battery change
The smoke detector needs two 3V lithium batteries.
These batteries are available in every electrical
goods shop. Do not use other batteries. Replace the
batteries once a year or immediately when the low
battery „beep“ signal sound once in 35 seconds. The
low battery beep should last at least 30 days before
the battery dies completely. To change the battery,
remove the detector from its base. Open the battery
housing and change the batteries. Then fix the smo-
ke detector to the ceiling again.
Cleaning the smoke chamber
Clean the housing with a dry or damp cloth to
remove dust and dirt. If necessary, open the smoke
chamber and clean the interior of the detector.
1. Remove the detector from the detector base.
2. Remove the batteries.
3. Insert a flat screwdriver in the gap and lift the
smoke chamber housing slightly.
4. Use a fine paintbrush to remove dirt from the chamber.
5. After cleaning, close the smoke chamber, fix the
housing and remount the detector on the ceiling.
Do not forget to replace the batteries.
