Radio-Interlinked Alarms

Radio-interlinked smoke alarms connect through radio frequency signals to ensure a fire alarm is heard in the entire building.
Product Overview

From the Firehawk W Series, this radio-interlinked home protection kit includes 2 optical smoke alarms (for living areas and circulation spaces) and 1 heat alarm (for kitchens and garages). The alarms are powered by sealed lithium batteries and communicate with each other wirelessly via radio-frequency so that all connected alarms will sound when one detects a potential fire. Additional Firehawk radio-interlink alarms can be added to the system for a total of 15 smoke, heat, and carbon monoxide alarms. All of the alarms in this kit also come with a 7 year manufacturer's warranty for peace of mind.

Please note: the battery in the wireless base is expected to last at least 7 years under normal use - when the battery has depleted in the base, the whole unit will need to be replaced.

When I finally worked out how to sync worked great I structures were not great on how to sync. Had to move jumpers on circuit boards. Once this was done for all worked fine.

A wee bit fiddly to link initially but all ok after reading the instructions very thoroughly a couple of times. Easy to fit/install.
