LHD-INT & LHD-EOL

Digital Linear Heat Cable Interface

Installation Guide

Introduction

This guide gives an overview of the installation of the digital linear heat cable interface and end of 

line unit. There are 2 distinct parts; LHD-INT and LHD-EOL but they operate as a pair. The units 

are a universal unit and should operate with most digital linear heat cables available on the market. 

However we supply and have tested these units exclusively with the LHDC supplied by PATOL. 

The purpose of the 2 units is to act as an interface between the fire control equipment and the digital

linear heat cable. This allows for a flexible cable to be routed to the initial position of the digital 

linear heat cable and then for end to end monitoring and testing between the LHD-INT and LHD-

EOL. At the INT position the status of the cable can be seen by the 3 LED status indicators and by 

pressing the two buttons on the EOL unit a fault and fire condition can be simulated without the 

need to open either terminating enclosure.
