Mains Powered Optical Smoke Alarm with Alkaline Back-up Battery - BRK 660MBX

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Please Note: BRK have withdrawn from the European market and there is no compatible alternative that will fit into your existing system.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.

FAQs (9)
Q. Do I need an ionisation or optical smoke alarm?
A.

We recommend using an optical smoke alarm in hallways, as these are less likely to go off because of cooking fumes from a connected kitchen. Optical smoke alarms are also ideal for living rooms, dining rooms, bedrooms, as they are good at detecting smouldering fires from soft furnishings. For landings we recommend ionisation alarms. Heat alarms are designed for kitchens and garages. No alarms should be installed in bathrooms.

Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?
A.

The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall. During a fire, smoke initially rises and then spreads to the sides of the room. By installing the alarm on the ceiling, this ensures that you receive the earliest possible warning of a fire.

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. When the test button is pressed on an interlinking smoke alarm will this cause all the other units to go off, too?
A.

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.

Q. If a false alarm goes off can pressing the hush button on any of the interlinking alarms stop all the units beeping?
A.

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.
