LHD – CTI Linear Heat Detector Cable

Protectowire CTI Linear Heat Detectors are advanced multi-criteria detectors consisting of models with alarm temperatures ranging from 68°C to 180°C.

The Protectowire CTI is the only digital-type linear heat detector capable of distinguishing between short circuits from mechanical damage and temperature-initiated alarm conditions.

The CTI LHD is a twisted pair of dissimilar spring conductors which are insulated with a heat-sensitive material. This material is designed to soften and allow the conductors to short when exposed to a specific alarm temperature. The dissimilar conductors, when shorted, form a temperature measurement junction called a thermocouple.

Fire Risks in Solar Panel Installations

Protectowire’s CTI Series Linear Heat Detector (LHD) is a fixed temperature detector designed to meet the detection challenges presented in solar panel installations. The CTI-220-XCR requires heat to generate an alarm condition; physical damage to the detector will not produce an alarm.

In addition, the Protectowire CTM-530 module has an integrated alarm point location to assist those responding to an alarm in determining the hotspot location. A fast response time can mean the difference between a controlled fire situation and a major recovery operation.
