Product Name:JTW-LD-997

Product Description

The 900 series is an analogue heat sensing cable containing insulators of which resistance varies proportionally to changes in temperature. Analogue cable is installed in conjunction with an end-of-line (EOL) device for continuity monitoring and a modulator providing selectable alarm thresholds (programmed before shipping), fire and fault outputs. This cable is self-restorable after the fire event as long as its temperature does not exceed specified resettable temperature limit of 120°C (248°F). Alarm points 85°C and 105°C are available to choose for different applications. The alarm point is not programmable on application field, the factory default delivery on model JTW-LD-997, please use ordering model number JTWLD-997-105 to order 105°C models.
