The JTW-LD-SF500/85A Cable Type Linear Temperature Sensor Fire Detector (hereinafter referred to as the detector) is a new type of reusable fire protection patent product that monitors changes in environmental temperature. It is mainly composed of a signal processing unit (microcomputer processor), a temperature-sensing cable, and connecting components (termination box). The detector has the function of responding to temperature alarms and outputting alarm signals.

Product Features

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

2. Integrated judgment of analog signal collection.

3. Meets the requirements of Section 4.18 for small-size high-temperature response performance tests 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 installation.

5. Features open circuit and short circuit fault alarms.

6. The microcomputer processor and terminal box housing are made of flame-retardant materials, offering corrosion and aging resistance.

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

8. The detector boasts strong anti-interference capabilities, utilizing isolation detection and software anti-interference technologies, suitable for use in environments with strong electromagnetic field interference.

Applicable Scenarios

The detector boasts excellent environmental adaptability and can operate reliably in close proximity for protection. It functions effectively in fire detection scenarios with humidity, contamination, and dust, making it widely used in warehouses, loading yards, oil and gas transmission pipelines, transformers, conveyor belts, locomotives, and distribution panels. Particularly suitable for early fire detection in power cables and control cables within cable tunnels, cable bridges, and cable wells.
