After unboxing it is required to activate and test the Smoke Alarm before installing it to the ceiling.

There are some major points of attention that you need to take into account.

After that follow the instructions below and watch the instruction video at the bottom of this page.

Press the activation pin on the backside of the smoke alarm. You can hear a short beep when the activation has succeeded

Attach the ceiling mount to the backside of the smoke alarm by turning it to the right as far as possible

Press the test button (on the front side of the alarm) preferably with two fingers in the middle. You will hear a loud alarm signal

Attach one part of the magnet to the ceiling mount ( do not attach it directly to the backside of the smoke alarm)
