Radio-interlinked smoke detectors and heat alarms are interlinked through radio-frequency. If one
smoke alarm detects fire, all alarms go off. In the case of the battery operated
radio-interlinked smoke alarms,
no wiring is required at all. The mains-powered smoke alarms require 230V supply,
example from the light fitting, but do not need to be linked to each other with
Radio-interlinked smoke alarms are sometimes also called wireless smoke alarms, although this can be confusing when dealing with radio-interlinked smoke alarms wired into the mains power supply in a building. Radio-interlinked smoke alarms communicate with each other with radio frequency (RF). If one alarm detects fire it will pass the signal to the other smoke alarms which will also sound an alarm. This is particularly important for large buildings or if the bedroom is far from the kichen. Outhouses can also be connectd into the radio-interlinked smoke alarm system. Radio-interlinked alarms can be battery powered or mains powered. We even offer a battery operated smoke alarm with radio-interlink that contains a sealed battery which lasts the full ten years of the alarm's life (Ei600RF series).
