Signaline HEAT Linear Heat Detector cables are designed to sense heat and can be used in conventional or addressable fire alarm systems. There are two types of Signaline Linear Heat Detector: analogue heat sensing cable and fixed temperature heat sensing cable.
Signaline HD is an analogue resettable linear heat detector that monitors significant increases in temperature. An electronic controller connected to the cable monitors the condition of the cable to sense any change in temperature by continually measuring the electrical resistance between the metallic core and screen. If the change in temperature is sufficient the controller creates an alarm. Signaline HD linear heat detectors are approved to EN54-5 by Vds.
Signaline Fixed Temperature Linear Heat Detector (Signaline FT) detects a build up of heat anywhere along its length. When any point along the length of the cable reaches a predetermined temperature an alarm is initiated. Signaline FT is available in four different temperature settings and two outer cover options making the Signaline FT suitable for use in a very wide range of applications. Signaline FT is UL and FM approved.
