How it works

The Digital LHDC operates by reacting to heat (fire). The insulators between the two conductors plasticise at the design temperature, creating a switch circuit at the point of operation.

The Linear Heat Detection Cable is employed in conjunction with an end of line terminating device for continuity monitoring and a zone monitoring controller to provide outputs for Fire and Fault. An LHDC controller with Distance Location (up to 2000m) to the point of operation is also available.

As the Digital LHDC provides a simple switched output on operation, the LHDC can be monitored by a conventional or Analogue Addressable zone monitor.
