MAN3111-3 1 Quick Installation Instructions Install cable into desired area. Pull the cable of the reel using a reel stand. Ensure the cable is correctly mounted. Strip the cable at both ends. Peel the foil back. A foil shield wire should be present which allows the foil to be grounded. This should be cut back at the end of line module end.
MAN3111-3 2 Important Guidelines Please read this instruction leaflet thoroughly before commencing installation. Support the detection cable at 1m (3ft) to 1.5m (5ft) intervals. Test the detection cable before installation using a multimeter. Ensure the maximum ambient temperature rating of the detection cable will not be exceeded during storage or normal operating conditions (-40°C to +90°C).
MAN3111-3 3 Introduction LST Analogue Linear Heat Detection Cable and Controller provide an easy installation method for sensing changes in temperature. The analogue technology offers separate Pre-Alarm and Alarm outputs in order to maximise functionality, coupled with open and short circuit detection and discrimination.
MAN3111-3 5 Typical System Configurations Conventional Fire Alarm Systems LST Analogue Linear Heat Detection (LHD) cable should be connected to the initiating device circuit on a conventional fire alarm control panel. Leader cable may be used between the interface unit and fire alarm control panel if the area requiring protection is some distance away from the control panel.
MAN3111-3 6 Installation Specifications Leader Cable Detection Cable The LST Analogue Leader cable should be used between A very important factor in determining which action the fire alarm control panel or addressable switch/zone temperature of analogue linear heat detection (LHD) cable to monitor and the Linear Heat Detection cable.
MAN3111-3 7 Installation Hardware There are many applications which Linear Heat Detection cable being spanned. Commercially available stainless steel wire with is used to provide protection for. Please see the Ampac Linear a diameter of approximately 2mm is suitable for use as a guide Heat Detection Cable Applications Guide for more information.
MAN3111-3 9 Splicing If the analogue linear heat detection cable gets damaged or has exceeded the maximum restorable temperature of 125°C (257°F), the section can be removed and a new section spliced in its place. Care should be taken during splicing to ensure the core conductors do not come into contact with each other at any point and the final spliced joint is secure and made waterproof.
MAN3111-3 12 Mounting Instructions The LST Analogue Heat Detector control module should be wall mounted (or equivalent) using four screws in each corner of the base of the enclosure. The fixing dimensions are shown in figure 1. Sensor Cable Minimum screw length 20mm Maximum thread diameter 4.5mm...

MAN3111-3 15 Control Module Setup (Laptop) If no self-programming module is installed (see page 11) the LST Analogue Heat Detector control module must be programmed using a laptop computer. To commission the control module firs ensyre the mimimum connections have been connected to the unit (See Control Module Wiring page 11).
MAN3111-3 16 Control Module Setup (Self - Programming Module ) If the self-programming module is installed, the LST Analogue Heat Detector control module can be installed without the use of a laptop computer. Once the necessary connections have been made to the PCB (see “Installation - control module wiring” page 7) the system should be powered on.
MAN3111-3 17 Alarm/Pre-Alarm Temperatures The LST Analogue Heat Detector is designed such that Temperature (deg C) for percentage length of sensor when a section, equal to 3% in length of the overall cable subject to overheat sensor cable length, reaches a user defined action temperature an alarm is triggered.
