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 interlinked alarms, causing them to also sound.

We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.
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.
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.
No, you do not need to remove all the batteries. Just simply press the house code button on all the units. Please ensure that the batteries have full power as this could render the house code process incomplete.
There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.
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.
