The Kidde Firex KF20LL is a mains powered optical smoke alarm with a replaceable 9v longlife lithium back-up battery which is designed to last the full lifespan of the alarm. The optical sensor is designed for use in escape or circulation routes and areas where there is a danger of ignition of furniture and surroundings producing slow, smouldering fires. Featuring a tamper-proof locking device which prevents unauthorised removal of the alarm without the appropriate tools and is fitted with a foam gasket to prevent the ingress of dust.
