Discontinued Product - No Compatible Replacement

Fitted with a sealed self-charging lifetime back-up battery, the BRK 760MRL (also known as 660MRL) is a mains powered optical smoke alarm with easy to install push-fit base plate. It's thermally enhanced smoke sensor makes the alarm less prone to false triggering whilst being quick to detect slow smouldering fires. The 760MRL can be interlinked with up to 12 compatible smoke and heat alarms (via cable) to ensure early warning if a fire is detected.
Please note: this product is not a direct upgrade from the 660MBX smoke alarm. Upgrading from a BRK 600MBX series alarm featuring an alkaline battery and twist-on base may require rewiring by a qualified electrician.

It is necessary that an electrician installs mains powered smoke alarms.
Yes, by pressing the test button on one alarm all the units in that family will also be activated. To 'teach' the units which other smoke alarms belong to the same family, the smoke alarms have to be set up together during the installation. This is done by pressing a 'housecoding button' or similar process.
No, to stop the alarms from sounding the hush button on the unit that started the process needs to be pushed. Pressing any other unit will just silence that one unit. The unit can be identified by the rapidly flashing red LED.
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.
