Kidde KF20 Mains Standalone Interlinked Optical Smoke Alarm (434PH)

Users say:
This product is a great replacement for old Firex alarms, fitting perfectly and being easy to install. It is suitable for mains and battery operation and defaults to battery operation in the event of mains failure. The light is quite bright, but is being picky.
