Optical Smoke Alarms

Optical smoke alarms are good at detecting smouldering fires such as soft furnishing. Best for living rooms, bedrooms & hallways.

Product Overview

This Firehawk W Series kit features three optical smoke alarms, one heat alarm and a carbon monoxide detector to provide protection and the earliest warning possible to fire or a CO gas leak. Each unit is powered by a sealed lithium battery, so no need to worry about changing batteries for the duration of the alarm's lifespan. For extra peace of mind the alarms can be wirelessly interlinked, so that when one alarm is activated the others will sound. This ensures that the whole household can be alerted to the danger. Additional FHB10W smoke alarms, FHH10W heat alarms and CO7B-10YW carbon monoxide detectors can be added to your system to expand the coverage in your home. All the alarms have a 10 hour Low Battery Silence while still remaining in full detection mode, to ensure that the household is safe while they sleep.
