The Wireless Site Alert Master unit has been designed to allow quick and simple set up of your fire alarm system. Manufactured by Howler, the alarms are easy to wirelessly link. Each unit is addressed using DIP switches, making the system fast to install with minimal staff needed.

In order to set up your system all you need is a master unit and subsidiary units to cover each area you need to raise an alarm in. Each system can have up to 30 subsidiary units linked to one master unit. The alarm can be raised by pressing the button on any of the units in the system and then pressing the button 3 times in succession on any unit to silence.

The master unit will advise of any connection or battery issues by way of simple LEDs on side of the light and still acts as an alarm itself. A weekly check of the master unit will show if any of the units within the group are not connected or have low batteries, with the indication also showing on the single unit with the issue. Made from robust materials to be weatherproof they really are the ideal solution to linked alarm systems that use wires to connect to each other.
