The Kidde Firex KF20 Optical Smoke Alarms provide reliable mains-powered fire detection for domestic and suitable commercial environments.
Designed as part of an interlinkable alarm system, multiple compatible alarms can be connected so that when one alarm detects smoke, the interconnected alarms can also sound — helping provide wider protection throughout the property.
Both models are mains powered with battery backup:
KF20 – 230V mains powered with 9V alkaline battery backup
Compatible alarms can be interconnected using the appropriate signal cable.
When one interconnected alarm is activated, the other compatible alarms within the system can also sound, helping occupants elsewhere in the property receive an earlier warning.
Up to 24 compatible alarms can be interconnected.
