Mains Powered Smoke Alarms & Heat Alarms with Alkaline Back-up Battery - Kidde Firex KF Series

The updated Kidde Firex range of smoke and heat alarms are mains powered, interlinking units that now use up to 70% less energy than previous Firex models. Hard-wired with alkaline back-up batteries, these alarms can be interlinked with other units from the series to create all round fire protection within the home; when one alarm detects smoke/heat and sounds, all units will sound. Installing the right sensor types in your property gives you the fastest possible response time with the minimum number of false alarms.
