Site Alert Subsidiary Wireless Unit

Our site alert wireless alarms from Howler have been designed to make setting your site with linked alarms easy and stress free . Able to use off the shelf alkaline batteries the alarms are simple to install and are made from robust materials to be weatherproof. Each unit is addressed using DIP switches, making the system perfect to use on a building project.

Covering your site is easy as you can use up to 30 subsidiary units linked to one master unit. The alarm can be raised by simply 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 keeps a check on the other alarms in the zone, using simple LEDs on the side of its light. If a subsidiary unit has a low battery or is not connected to the zone the master unit will show a fault within the zone, a simple check of the subsidiary units will then show the unit that has the issue. These checks should be done weekly when the other weekly checks are being done on the site.
