Kidde FireX KF20R Optical Smoke Alarm Rechargeable Battery Backup

The Kidde Firex KF20R is a mains powered optical smoke alarm with a sealed rechargeable lithium back-up battery which is designed to last the full lifespan of the alarm with no need for replacements.

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, smoldering 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. 

Interconnectable to up to 23 other Firex or Kidde Slick mains alarms via signal cable, installation of this optical smoke alarm could not be easier.

Fully conforming to BS 5839-pt6 Grade D, the 4973 alarm has a 6-year warranty and a hush and test button as standard. The Firex KF20 has a lower lifetime running cost compared to most alarms due to its reduced energy consumption. 

This alarm is also suitable for both the Welsh and Scottish updated 2022 legislation.
