Patol 700-201 LDM-519-LP LHDC Interface & Fire Zone Monitor
The module is designed to monitor a zonal length of Analogue cable for both an elevated temperature (Fire) condition, and Fault Status (Open & Short Circuit). It operates in conjunction with a single core coaxial cable and an end of line (EOL) terminator. The module provides early warning of hot spots and fire conditions on short sections of the overall zone length. Maximum Zone length for LHD Analogue cable is 500m when connected to this module.
It is designed so that it can be configured to operate in two wire mode that emulates the operation of conventional heat detectors allowing for direct interfacing with the Fire Control panels trigger circuits.
Signalling of Fire and Fault Status by means of Volt Free Contacts may also occur when a separate power supply is used. The modular form of the unit enables it to be provided in a variety of discrete housings and readily integrated into special control panels.
