Smart Home Siren 2151: Loud alarm & visible deterrent

Alarm and deterrent all-in-one: The Siren 2151 can be installed inside or outside the home. Installation ourdoors benefits from an additonal visual deterrent to potential burglars who may see the alarm and avoid it. Siren 2151 is part of the BURGprotectTM smart home series from BURG-WÄCHTER. The alarm siren is linked to the central control unit Base 2200 via the BURGprotectTM app with a simple scan of a QR code. Pairing occurs within a matter of seconds and once this is done the alarm is operational.

120 decibels alerts the neighborhood

In the event a sensor within the BURGprotectTM range is triggered, the deafening 120 decibels Siren 2151 alarm is activated. The maximum siren volume is as loud as the noise of a jackhammer. An in-built strobe also flashes to provide a visual warning signal. Not only is the neighborhood made aware of the alarm but the burglar is very likely to run away when his cover is broken. Furthermore, thanks to the smart home technology a notification is sent to the user when the alarm and sensor is activated.
