Fitted with a sealed lithium back-up battery, the BRK 790RF is a mains powered radio-interlinked heat alarm designed for kitchen areas and garages. The radio-frequency base plate supplied with the heat alarm enables the unit to wirelessly interlink with multiple smoke and heat alarms within the same system, providing the earliest possible warning of fire. If one alarm is activated it will send a wireless signal to all other interconnected alarms, causing them to also sound.

Q. What smoke alarm should I use in a bedroom with an en suite bathroom?
A. It is usually recommended to install an optical smoke alarm in a bedroom. This is because optical smoke alarms are slightly quicker at detecting slow smouldering fires than can original from upholstery type materials and over-heated wiring. Also, an optical smoke alarm would be less likely to sound a false alarm than what an ionisation would do if steam/water droplets were present from the bathroom. Detectors should be installed as central to the room as possible; however for your application I would also consider the position of the en suite to make sure that the detector is not in the direct path of the joining door. This is just to try and avoid the chances of a false alarm. No detector is designed for use in bathroom areas.
Q. My ceiling light is on a dimmer switch. Can I still power my radio-interlinked mains smoke alarms from this lighting supply?
A. In modern housing the lighting circuit will travel around your house with the lights being fed from it. Between the circuit and the light will be a switch (or in this case a dimmer) which will control the light. Your mains powered alarms are connected directly to the circuit and have constant power, so are not affected by switches or dimmers.
In older homes that have not had the electrics updated this may not be the case so it is advisable to consult an electrician.
Q. How do I safely dispose of my old smoke alarms?
A. Safelincs is signed up to Valpak's WEEE (Waste Electrical and Electronic Equipment) Distributor Take-Back Scheme (Registration ID: 7370). Private households can therefore drop off their electronic and electrical fire safety waste at their municipal recycling centre when they are purchasing new products from us. To find your nearest recycling centre, please visit www.recycle-more.co.uk.
Q. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
A. Yes, hard-wired mains powered alarms can be wired to the unswitched live feed of the nearest frequently used lighting circuit.
Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.
A. Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.
