Putting into operation
Insert batteries (2× 1.5 V AA) into the battery compartment on the back.
Only use alkaline batteries of the same type, never use rechargeable batteries.
When inserting batteries into the area with plastic clips, be careful to insert the battery properly!
See figure Insertion of batteries.
After inserting the batteries, a red LED will flash.
The LED will then flash red every 40 seconds, indicating the detector is functional.
Warning:
The assembly cover cannot be shut unless all batteries are in place!
The plastic clip in the battery compartment prevents the mounting of the assembly cover.
It is necessary to always have all batteries inserted and the mounting plate in place to prevent the
batteries from falling out of the battery compartment.
Testing mode
Whenever needed or during every battery replacement, you can test the functionality of the detector.
Long-press the main button for ca 5 seconds; the detector will beep 3× in a row (then a 1.5 second
pause will follow) and a red LED will flash.
If the detector does not emit an acoustic signal, check the batteries and assembly.
Do not hold the main button for more than 12 seconds, or the detector will switch to mode for
pairing with other units.
It is possible that other paired alarms will also begin beeping during testing (if you are using multiple
alarms in the residential space).
After releasing the main button, the other alarms should stop beeping within 1 minute.
Use testing mode 1× a week to make sure the alarm is operational.
Note:
The acoustic and optical alarm during testing is only used as indication that the detector is operational.
It does not mean that the presence of smoke has been detected.
Fault state
If the detector is in fault state, it is not functional.
The fault state is indicated every 40 seconds by 1 beep and 20 seconds after the beep by 1 flash
of red LED.
Immediately replace the batteries and check that the detector is undamaged; clean the openings of
the detector by e.g. a vacuum cleaner. Perform a functionality test.
If the fault state persists even after batteries have been replaced, contact the service centre.
Flat batteries
Flat batteries in the alarm are indicated by simultaneous beeping + flashing of red LED 1× every 40
seconds.
Immediately replace batteries. Use alkaline batteries only, not rechargeable ones.
Perform a functionality test.
It is recommended to replace batteries 1× a year as a precaution.
Manual silencing of acoustic signal for flat batteries
If needed, the acoustic signal can be temporarily silenced.
Press the main button during alarm mode; the acoustic signal will be silenced for 8 hours (the red
LED will flash every 8 seconds).
End of service life of the detector
The detector has a service life of 10 years since production.
After expiration, the detector must no longer be used and must be replaced with a new device.
The replacement date for the detector is listed on the label on the back, next to „Replace device".
If you are using multiple detectors, remember to check their replacement dates!
Alarm warning
If smoke is detected, the detector will start emitting an acoustic + optical signal.
