Wireless Site Alert Subsidiary Unit

Manufactured by Howler, the wireless site alert alarm is the most novel way of connecting a set of alarms on a site. The system is designed such that a master unit connects to up to 30 subsidiary units. When connected, setting off one alarm will cause all the other alarms in the group to go off. The alarms use simple alkaline batteries and a very easy to install and use. Each of the alarms is identified using DIP switches.

To raise the alarm, you only need to press the button on any of the units. This will automatically turn on all the other units in the group. To turn them off, press the same button 3 times in quick succession. Each of these weatherproof wireless site alert units has a strobe panel that has simple LEDs that effectively indicate when the battery is low and whenever a unit is disconnected from the group.
