Description
The Defender press and evacuate alarm has four moulded depressions in the back mounting plate for easy wall or post mounting.
This standalone fire alarm can be linked to 25 Defender HFR100 models in parallel using a suitable twin-core bell wire. + and – terminals should be linked from each unit through the screw terminals.
We recommend the Defender HFR100 is tested weekly and the PP3 battery replaced every 12 months using zinc or alkaline batteries.
