The Ei3100RF smoke is battery operated and has a built-in radio-interlink facility.
Requiring no wiring whatsoever, up to 12 alarms can be interlinked to form a single system and the interlink is achieved wirelessly by radio signal.
When one alarm sounds, it sends a signal to all other interlinked alarms and sounds those too.
This radio-interlinked feature provides occupants with the earliest possible warning of fire.
