Replacement Smoke Alarm for BRK 660MBX and 670MBX - easichange® SBBRKSM

The SBBRKSM easichange® kit replaces the discontinued BRK 660MBX optical and 670MBX ionisation smoke alarms and fits onto your existing BRK twist-fit alarm baseplate so there's no need for any DIY or an electrician. The kit consists of the replacement optical smoke alarm head with pre-connected easichange® adaptor, an easichange® removal tool, a quick change guide, and the full alarm manual.

The SBBRKSM is a mains powered smoke alarm with a replaceable 9V alkaline backup battery like the 660MBX and 670MBX that it replaces. The optical sensor technology improves on the detection of slow smouldering fires and reduces the chances of false activations. Featuring a hardwire interlink allowing compatible easichange® alarms to communicate with each other over the same wiring as your old BRK alarms, so that all will sound the alarm if one detects a fire.

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 turned off before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.

Please Note: We recommend replacing all alarms in the system together to maintain optimum system operation; failing to do so may compromise interlink performance.
