alarm siren
The alarm siren triggers a very loud warning tone, often in combination with an optical signal (e.g. flashing). The alarm siren is part of the alarm system . In the smart home, the alarm siren can be linked to motion detectors: if an intruder moves through the room, the motion detector sends a signal to the smart home system and the smart alarm siren is automatically triggered.
