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.

These alarms are replacements for existing Firex alarms and were just a simple matter of replacing plug-and-play items.
Five minutes, and they were both done. Easy peasy.
