Product Overview

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.

FAQs (2)
Q. How long do the batteries last in smoke alarms?
A.

The 9V alkaline batteries and AA alkaline batteries generally last 12 to 18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime. Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm. Newer alarm models may also feature a "sealed" lithium battery. These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.


Please note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.

Q. What sort of smoke alarm system would I need to install for a HMO?
A.

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.
