JTW-LD-JBF4310

Overview
JTW-LD-JBF4310 temperature sensing cable has the ability to continuously monitor the temperature of the protected object of its full length. It has the functions of fixed temperature alarm, rate-of-rise alarm, and adjustable multi-level sensitivity, which can quickly report the fire situation. It has excellent anti-interference ability and can effectively avoid false alarm. Main application scope: cable trench, tunnel, interlayer, substation and other places.

Product Features
Long detection range of temperature sensing cable: 10-1000m.
Detector type: recoverable, fixed temperature and rate-of-rise heat detector, its standard alarm length is 1m.
Alarm threshold setting: fixed temperature alarm threshold 85 ℃, 60℃-85 ℃ settable.
View temperature in the field: the display interface can check and display the temperature of the detection point of the temperature sensing cable.
Regional alarm temperature setting: alarm threshold can be set separately in different zones, range 60-85 ℃.

Dimensions and installation

For the fire detection in the cable area, the temperature sensing cable should be laid with sine wave contact.

Notes: for other applications, please follow the relevant design specifications or contact the manufacturer.

Attention
The sensing cable is different from ordinary cables. Excessive extrusion will cause mechanical damage inside the cables and cause false alarms. Therefore, the following principles should be followed in the installation process:
1) When laying the sensing cable, the pull tension shall not be greater than 100N, and the bending radius shall be greater than 30cm.
2) Avoid heavy objects sitting on the cable. The sensing cable should be installed in places free of mechanical damage.
3) Pay attention to the polarity of the cable connection. Reverse connection will cause cable damage.
4) When there are joints in the sensing cables, the junction box must be added. The wiring must follow the requirements, and the sealing of the junction box must ensure the stable operation of the sensing cable.
5) Do not open the cover with power connected. Non-professional personnel are not allowed to install or dismantle the product.
6) After connecting the cable, restore the sealing ring to the original position and tighten the box cover.
