Ideal for areas where a standard smoke alarm would be unsuitable, such as kitchens and garages, the BRK 690MBX is a mains powered heat alarm designed to detect rapid increases in room temperature. Kitemarked to the latest standards and with a 5 year manufacturer's warranty, the BRK 690MBX also benefits from multi-alarm interlink feature, meaning that it can be hard wire interlinked with up to 12 compatible smoke and heat alarms within a system.
Please note: for surface-mounted wiring such as trunking the base plate included with this alarm is not suitable; please see the BRK 790MRL with push-fit base instead.

Product Datasheets |
We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.
The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/ Also see the LACoRS guide for let properties.
There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
