JBF6117 Insulation Performance Fire Detector is an electrical device that collects the three-phase voltage value and the residual current value of the power supply line, analyzes the residual current, and separates the residual current from the resistive leakage component to determine the leakage of the line. The fire monitoring detector can effectively ensure the safe use of electricity and prevent electrical fires, and can be widely used in the power supply unit of fire system for dangerous goods storage places, high-rise buildings, public areas and residential buildings.

Wiring

Detector terminal wiring is as shown in the figure below:

 
L, N: power wiring terminals (AC 220V, 50Hz)
L1﹢, L1-~L3﹢,L3-: Connection terminals for connecting residual current transformers of detectors
IN﹢, IN-: Connection terminals for connecting N-phase current transformers
UA, UB, UC, UN: three-phase four-wiring voltage input terminals
L1, L2: For the two-bus terminal
FIRE: for the alarm relay output node
FAULT: for the fault relay output node;
 

• Attention

Wiring is forbidden when the power is on.
