This is the master unit of the wireless site alert alarms system. This unit connects other subsidiary units to create a group of up to 30 units. When any of these units is set off using the alarm button on it, all the other alarms in the group get turned on. To turn them off, you only need to press the same button 3 times in succession. A perfect solution for the wired systems, this system features 8 channels for use in multiple zones.

Made by Howler from strong and durable material, this weatherproof wireless site alert master unit is powered by off-the-shelf alkaline batteries. The unit has simple LEDs to warn you of low battery levels and to indicate when the unit is disconnected from the rest. Easily installed, the system is designed such that each unit is addressed using DIP switches.
