Patol 700-003 Linear Heat Detection Cable

The Patol analogue linear heat detection cable (LHDC) is designed to provide early detection of fire and overheating in circumstances where other forms of detection would not be viable, either due to inability to sustain the environment requirements or through prohibitive costs. Extensive single zonal lengths of the LHDC may be installed with the ability to trigger alarms for hot spots occurring on very small sections of the overall cable.

LHDC Analogue is a coaxial cable constructed with a copper coated steel central conductor, an inner insulation (dielectric), a tinned copper braid layer and an overall protective sheath. The primary mechanism of heat (fire) detection is that the resistance of the dielectric, monitored between the central conductor and braid layer, has a negative temperature coefficient (NTC).

Analogue cable is employed in conjunction with an end of line terminating device and a zone monitoring unit or control panel with an appropriate LHDC interface channel. LHDC may be installed in Hazardous areas by means of Intrinsically safe zener barriers. Similarly when the protected area is remote from the monitoring equipment interposing cables may be employed.
