Activating smoke alarms

More often than not, smoke alarms come with batteries included. To ensure that this battery is not draining before the smoke alarm is put into operation, the smoke alarms are completely turned off in the beginning and therefor need to be activated.


The below description works for the following smoke detectors: FSM-121, FSM-123, FSM-127, RM217, RM218


To activate a smoke alarm, please follow the steps below:

As soon as the LED indicator turns red, the button should be released immediately. The smoke alarm will make a chirping sound.
The smoke alarm should now be properly activated.

Try pressing and holding the test button briefly to test the alarm. If there is no alarm ringing and no LED indicators are flashing, please contact our Customer Service team.
