Mains Powered Heat Alarm with Alkaline Back-up Battery - BRK 790MBX

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Please Note: BRK have withdrawn from the European market and there is no compatible alternative that will fit into your existing system.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 700MBX range is the Kidde Firex series. This will require an electrician to replace your old BRK bases with new Kidde bases.
