JBF6119

Temperature-measuring Electrical Fire Detector


JBF6119 temperature-measuring electrical fire monitoring detector is a non-independent small detector, needed to be used with electrical fire monitoring equipment. By detecting the temperature of cables, power distribution box, and electricity equipment, ensure the safety of electricity usage and prevent the occurrence of electrical fires. The detectors can be used monitoring the power supply system in warehouse with dangerous materials, high-rise buildings, public places and residential buildings, or monitoring large-scale electrical equipment that easily accumulates heat.
 
Product Features
•  The detector has an indicator to distinguish various operating states by different colors. Green light flashing represents normal working state, and steady on red represents alarm state.
•  Temperature rate-of-rise detecting.
•  Transmit real-time temperature values and fault signals to the connecting electrical fire monitoring equipment.
•  Small size, suitable for different types of cabinets.
•  Support fixed or rail type installation, fast and convenient.

Structure and Dimensions

 
Wiring
•  The detector is connected to the electrical fire monitoring equipment. As shown in the following figure, connect L1, L2 of the JBF6119 type electrical fire monitoring detector to the signal loop that connect to L+ and L- of the electrical fire monitoring equipment.
 
Precautions
•  The loop should adopt ZR-RVS-2 x 1.5mm2. When laying cable, the strong electrical wiring must be separated from this wiring;
•  When the communication cable is of shielded twisted pair, the shielding must be well grounded.
•  The temperature sensor and the cable must be in good insulation.
