Kidde Alarmline Digital cable 68 Deg C, PVC - 500m (PVC outer sheath)

The Kidde AlarmLine AD68-0500 is a Digital Linear Heat Detection (LHD) cable with a 68°C (155°F) fixed temperature activation rating. It has a standard PVC outer sheath making it suitable for internal applications and is supplied in 500m lengths.

The AD range of digital LHD cables contain a pair of twisted, low resistance, tri-metallic conductors sheathed with advanced temperature sensitive polymers. The cable operates by softening the insulation of the conductors, the tension of the twisted conductors then causes the two cores to fuse together. The sensor cable provides a simple switch operation which when used with a combination of end-of-line (EOL) monitoring and alarm trigger resistors can signal an alarm to any fire monitoring equipment through any monitored input i.e. conventional detection zone or addressable interface unit.
