The BRK Easichange® kit replaces the alarm head of the DETA 1111 ionisation and 1113 optical alkaline smoke alarms. This kit contains a BRK 660MBX alarm head, 9V alkaline battery, Easichange® tool, instruction manual and quick replacement guide.
The BRKEOA is an optical smoke alarm with alkaline battery. The thermally enhanced sensor makes it ideal for installing in hallways, bedrooms, landings and living areas, including those rooms adjacent to kitchens or in rooms with open fires. Less advanced alarms can be triggered by cooking fumes - the optical sensor in the BRKEOA will reduce this significantly. A central test/hush button makes maintenance of your alarm quick and simple. The replaceable 9V backup battery will ensure you remain protected even in the event of a power cut.
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.
