When does siren set off the alarm?
The siren is automatically activated, if somebody tries to open a door with an attached door sensor violently. You only have to trigger it in the App. Simply go to CONFIGURATION > INTRUSION and tick the box next to siren.
You can activate siren for the away mode as well by ticking the box in CONFIGURATION > AWAY > SIREN. Now the siren will emit a loud noise if you´re not at home and the sensors detect movement or the opening of a window or a door.
