JBF6186

The JBF6186 voltage signal sensor is a bus addressing type field device for monitoring 3-phase 3-line dual power supply system. When the power supply of the monitored fire equipment malfunctions, for example, power interruption, overvoltage, under-voltage and other faults, the sensor will transmit the above fault signals to the monitor and the monitor willgive out sound and light alarm signal.

Product Features
(1) the sensor is encoded by electronic encoder, and the address range is 1 ~ 252.
(2) the wiring between the sensor and the monitor is of no polarity, and by which both the power supply and the data transfer of the sensors are realized.
(3) the sensor is equipped with two indicators. Flashing green light represents normal operation, and constant yellow light stands for fault.
(4) the sensor monitors the voltageof duel 3-phase 3-linefire equipment power supply in real time, and can report various faults in 100 seconds, for example, power supply interruption, overvoltage, under-voltage.
(5) the sensor can transmit the monitored voltage value to the monitor.

• JBF6186 structure and dimension figure

Wiring
(1) use encoder to write addresses for sensors.
(2) install the sensor on the 35mm standard guide rail in the fire power distribution box.
(3) connect the non-polarity loop bus lines to the L1/L2 terminals of the sensor.
(4) connect the output lines of the monitored duel 3-phase 3-line AC fire power supply to terminals of U1AB，U1BC，U1CAand U2AB，U2BC，U2CA.
(5) the wires of the loop should be soft double stranded wires with a diameter not less than 1.5mm2 (rvs-2 x 1.5mm2).
(6) the wires for connecting the sensor and the output ends of the power supply should be copper cables of a diameter no less than 1.5mm2 (RVS-6x1.5mm2).

Normal Display State of the Sensor
When each sensor circuit is connected right and the monitoring voltage is normal, the sensor LCD screen displays the current monitored voltage value and the address of the sensor in each loop, as shown in the figure below:

Note: when the voltage signal sensor "voltage detecting input end” getsa power outage (or empty load), yellow fault light of the sensor is lit, and the LCD screen is dark. The monitor will displaythe info of this sensor as "power failure".
