Resettable Linear Heat Detector LHD-PACC

The resettable linear heat detector LHD-PACC has separate relay outputs for pre-alarm, fire alarm and system fault for triggering detector zones on an alarm transponder 808623.40 / M721E Dual Input - Single Output Module.

Due to the differentiated ambient temperature compensation, the window of the set alarm temperature balanced and alarm temperature accuracy maintained. The system is resettable after an overheating or fire condition, if the monitoring sensor cable is not temperature above the maximum recoverable temperature, or mechanically damaged. The Monitoring of the sensor line is carried out via the termination module PACC art. no. 762292 (not in scope of delivery), in which reference measuring resistors for line monitoring are integrated.
