Even safer thanks to effective siren alarm

The wireless indoor sounder SR-S1 ensures an effective volume of your alarm system on different floors or additional building spaces. It also allows different alarm tones: one for events, another in case of fire, and another in the event of an alarm.  And it lets you know immediately what that event is (z. B. burglary, fire or water damage) and can react accordingly.

An important side effect - you should have a smoke detector integrated in the system, so it can naturally strengthen the effectiveness of the alarm. In case of fire, the siren will alert everyone surrounding your home.

Network your wireless indoor siren quickly and easily with a few clicks of the alarm system. Thanks to the radio-based operation of the wireless indoor siren, you can simply attach the siren on any wall or ceiling.
