Patol Analogue LDM-519-SEN-N LHD Fire Zone Monitor with Two Level Set Alarm Points

Patol Analogue LDM-519-SEN-N LHD Fire Zone Monitor with Two Level Set Alarm Points

Patol Analogue LDM-519-SEN-N LHD Fire Zone Monitor with Two Level Set Alarm PointsThe SEN-N Controller is designed to monitor a zonal length of resettable Analogue Linear Heat detection Cable LHDC for both an elevated temperature Fire condition and Fault Status Open Short Circuit. The Controller offers two adjustable levels of alarm A1 A2 one of which may be optionally employed as a Pre Alarm. The LHDC is also monitored for fault conditions open and short circuit.LHDC is of coaxial construction and is used in conjunction with an End of Line EOL terminator. The Controller provides early warning of hot spots and fire conditions on short sections of the overall LHDC zone length. Maximum LHDC zone length for Analogue cable is 500M. The modular form of the unit enables it to be provided in a variety of bespoke housings and readily integrated into special control panels.Key FeaturesTwo level alarm set pointsAdjustable alarm set pointLED indication of Fire Fire and Supply statusWire dc supply operation -20vdc to -60vdc positive earthedFault monitoring for open short circuitsSelectable Latching Auto reset operationVFC relay outputs fore Fire Fault conditions
