The Site Alert wireless master unit has been built from robust weatherproof materials for the modern building site where it is not easy to run cables to power and connect fire alarms together. Made by Howler the alarms are perfect for quick and easy install for short or long term projects. The master unit is used as the point for the other alarms in the zone to be linked to, each unit is addressed using DIP switches and it only takes a few staff members to set them up.
Every master unit can have up to 30 Subsidiary units linked to it and the system can be easily activated by pressing the button on any unit within the zone, to deactivate simply press the button 3 times in succession on any alarm.
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.
