Patol LDM-519-LP SIL 2 Certified Analogue Linear Heat Controller
£584.83 (inc VAT: £701.80)
Summary
The LDM-519-LP is a sophisticated LHDC Interface designed for monitoring analogue cables. It is engineered to detect elevated temperatures indicative of fire conditions, as well as fault statuses such as open and short circuits. This module works in conjunction with a single core coaxial cable and an end of line terminator, offering early warning for hot spots and fire conditions over a maximum zone length of 500 metres, subject to ambient temperature and configuration.
Designed for versatility, the LDM-519-LP can be configured to operate in a two-wire mode that emulates conventional heat detectors, allowing direct interfacing with fire control panels. Additionally, it supports signalling of fire and fault status through volt-free contacts when a separate power supply is used. Its modular form allows for integration into various discrete housings and special control panels.
