Temperature sensing cables, as common linear temperature sensing fire detectors in fire alarm systems, inevitably encounter problems during use. So why do problems occur and how can they be resolved? Below, the fire alarm system manufacturer will explain to you.

　　Common Fault Handling:

　　1. When there is a fault in the detector, you can check the corresponding parts based on the display status of the LED indicator on the signal processing unit, and take appropriate measures. First, confirm whether it is a problem with the temperature sensing cable itself, or it may also be an issue with the input module connected to the temperature sensing cable.

　　2. When there is a joint in the detector, a temperature sensing cable junction box must be used, and the wiring must be installed as required to ensure the stable operation of the detector. This can prevent or reduce the occurrence of open circuit or short circuit in the temperature sensing cable.

　　3. For detectors with occasional false alarms or false fault alarms, records should be kept, and the following aspects should be investigated to identify and eliminate the faults:

　　- Check whether the signal processing unit, temperature sensing cable junction box, and terminal unit are well sealed.

　　- Check for any damage to the sheath of the temperature sensing cable.

　　- Check whether the terminal connections of the signal processing unit, temperature sensing cable junction box, and terminal unit are secure and reliable. The continuity of the temperature sensing cable can be measured with a multimeter.

　　4. If the detector fault cannot be eliminated, please contact us promptly.
