JTW-LD-SF500/105A Cable-Type Linear Temperature-Sensing Fire Detector (hereinafter referred to as the detector) is a new type of reusable fire protection patent product that monitors environmental temperature changes. It is primarily composed of a signal processing unit (microcomputer processor), a temperature-sensing cable, and connecting components (termination box). The detector is capable of responding to temperature alarms and outputting alarm signals.

Product Features

The thermally sensitive cable has a stable structure, strong anti-interference and tensile, as well as crush resistance properties.

2.   Integrated judgment of analog signal acquisition.

3. Meets the small-size high-temperature responsive performance test requirements of section 4.18 in GB16280-2014 and the requirement of section 12.3.3 in GB50116-2013 that the flame response size does not exceed 100mm.

4. The sensor cable remains undamaged after an alarm in the safe temperature range, allowing for reusable sensor cable.

5. Features open circuit and short circuit fault alarms.

6. Microcomputer processors and terminal box shells are made of flame-retardant materials, offering corrosion and aging resistance.

7. Equipped with manual fire alarm and fault simulation features.

8. The sensor boasts strong anti-interference capability, utilizing isolation detection and software anti-interference technology, suitable for environments with strong electromagnetic field interference.

Applicable Scenarios

The探测器features excellent environmental adaptability, capable of operating reliably in close proximity or near protection in fire detection environments with various levels of humidity, contamination, and dust. It is widely used in warehouses, loading yards, oil and gas transmission pipelines, transformers, belt conveyors, locomotives, and switchboards for fire detection. Particularly suitable for early fire detection in power cables within cable tunnels, cable trays, and cable wells.
