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 temperature setting ranges between 70°C to 130°C(158°F to 266°F). Customer can specify its own alarm temperature setting. The factory default setting is set at 85°C(185°F).
