UltraFire battery powered heat and optical smoke alarms can be radio-interlinked with each other, up to a total of 50 units, to create a wireless alarm system within your home. Powered by two 1.5V alkaline AA batteries, these alarms have a wireless range of up to 100m in open air and 35m indoors. Heat alarms are designed for use in areas prone to false alarms caused by dust or steam and cooking fumes, such as kitchens, garages and unconverted loft spaces. Optical smoke alarms are less susceptible to false alarms caused by cooking fumes, making them suitable for installation near (but not in) kitchens as well as in living rooms, bedrooms, hallways, and landings. Optical smoke alarms are also suitable for rooms which have traditionally been protected by ionisation alarms.
Please note: These Grade F2 alarms are not suitable for the new fire and smoke alarm standards in effect in Scotland from February 2022. To meet those requirements please choose from our dedicated selection of Scottish compliant alarms.

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.
Most radio-interlinked alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal.
It is recommended that smoke alarms are replaced after 10 years. This is because the sensors in the smoke alarms become less sensitive and may not activate when a fire is present.
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.
Smoke alarms can be either screwed to the ceiling using the holes on the base plate (screws provided) or fixed using a sticky pad, this can be added to your basket through the ordering process.
