The manufacturer has withdrawn from the European market and is no longer supplying compatible alternatives. Since it is not possible to interlink alarms from different manufacturers, the recommended replacement for the whole discontinued BRK 600MRL range is the Aico Ei3000 series.

Q. Do you need an electrician to connect mains powered smoke alarms?
A.
It is necessary that an electrician installs mains powered smoke alarms.
Q. Can a smoke alarm be fitted with a sticky adhesive pad in a let property?
A.
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.
Q. What sort of smoke alarm system would I need to install for a HMO?
A.
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.
