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.
