The BRKEHA Easichange® kit is the replacement for the DETA 1115 heat alarm which is fitted to a slimeline twist-on base plate and uses alkaline batteries. The kit is comprised of the replacement alarm head, Easichange® removal tool, 9V battery, quick change guide, product manual and a reminder sticker to place in your fuse box.
The DETA 1115 was a rebranded BRK heat alarm, using the same base plate and interlink system. The BRKEHA Easichange kit includes a brand new BRK 690MBX heat alarm which is the latest compatible model and can be swapped over in minutes without any rewiring or the need for a qualified electrician. The nature of heat alarms means they are ideal for kitchens, garages, unconverted loft spaces, and other rooms where smoke detectors would suffer regular false alarms due to dust or fumes. A total of 12 compatible alarms can be interlinked together into a single system so that all alarms will sound if one detects a possible fire, ensuring all occupants are warned about the danger.
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.
