The BRKEHL Easichange® kit is the replacement alarm head for the BRK 790MRL heat alarm with lithium backup battery. This alarm is designed for installation in kitchens where traditional smoke alarms can easily be triggered by normal cooking fumes. The lithium battery provides continuous alarm coverage in the event of power outage, and will never need replacing for the entire warranty life of the alarm.
Included in the kit are a BRK 790MRL alarm head, full product guide and quick change guide, plus a free Easichange® tool that will make removal of the old alarm and installation of the new BRKEHL a quick and simple process. The alarm head fits onto your existing 790MRL base and requires no additional wiring.
The simple installation process of the Easichange® replacement kits negates the need for an electrician, though you must ensure that mains power to all interlinked alarms is cut before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.
Below is a table of all alarms which can be interchanged using the same base plate and interlink system. Care should be taken to ensure the correct model is purchased to replace existing alarms. Optical smoke alarms can be used in place of ionisation smoke alarms, but heat alarms and smoke alarms serve different purposes and cannot be swapped.
