Discontinued Product - No Compatible Replacement
Please Note: BRK have withdrawn from the European market and there is no compatible alternative that will fit into your existing system. Since it is not possible to interlink alarms from different manufacturers, new alarms will be needed throughout. The recommended replacement for the whole discontinued BRK 600MBX range is the Kidde Firex series. This will require an electrician to replace your old BRK bases with new Kidde bases.

Interlinked with up to 12 compatible alarms, the BRK 670MBX is a mains powered ionisation smoke alarm with a 9V alkaline back-up battery. The 670MBX smoke alarm is quick to detect fast flaming fires, sounding an 85dB audible warning and is typically installed in landing areas. The BRK 670MBX is Kitemarked to the latest British Standards and has a 5 year manufacturer's warranty.
Please note: the packaging may show a product code of 770MBX and include a push-fit base but the alarm itself is still a 670MBX, as shown on the sticker on the back of the alarm head, and it is still compatible with existing twist-fit bases. If you are having difficulties with the removal of the alarm from the push-fit base, please see our video that demonstrates the removal.

It is necessary that an electrician installs mains powered smoke alarms.
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.
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.
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.

Feeling safe again. I had hoped to be able to fit this myself as it was a replacement for one that was 10 years old but I found the slight change of design meant I had to get an electrician in. Sorted now though and it is good to know we are safe at home.
