Pertronic-Anbesec linear heat detection (LHD) cable is a heat sensing device with a fixed temperature alarm threshold.

The cable consists of two twisted steel wires separated by heat sensitive insulation. The insulation melts at a pre-determined temperature, allowing the wires to contact each other and create a short circuit. When correctly connected to a Pertronic fire panel, the LHD cable triggers an alarm signal when the insulation melts.

Pertronic-Anbesec LHD cable may be connected to all current Pertronic fire panels including

• F1
• F4
• F16e
• F100A
• F220

LHD cable sensitivity is not affected by installation temperature or the length of cable heated by a fire.
