In the event of a burglary, experience has shown that the burglar first goes after the source of the alarm tone. If the indoor siren is connected to the alarm control unit, there is a danger that the alarm control unit will be destroyed.
This can be prevented by the fact that the indoor siren is located at a different location than the control unit and is started by means of a radio signal. This radio signal can also be used to start several indoor sirens in different rooms at the same time, which considerably increases the psychological pressure on the burglar. The built-in timer switches the siren off automatically after 3 minutes (adjustable).
