Wireless outdoor siren.

This is a wireless external siren that works with the our alarms.

The siren comes with a 12v power adapter to power it and has an internal back up battery in case of power failure.

A small battery transmitter supplied is connected to the siren output of an alarm.

When the alarm is triggered the transmitter sends a signal to the wireless siren which then sounds the 120db siren and the strobe lights flash.
