Features:
PS-XFFJ-G series fire electrical control device (smoke prevention and exhaust fan, dual power supply control equipment) is composed of dual power automatic switch, circuit breaker, AC contactor, motor protector, phase loss and phase sequence, overvoltage and undervoltage Protector and other low-voltage electrical accessories. The equipment also has manual and automatic operation modes; phase loss and phase sequence protectors. If undervoltage is detected in a three-phase AC circuit, any phase fuse is open, or there is a phase failure in the power supply line, the JD will act immediately and control the contacts to cut off. The main circuit AC contactor coil supplies power, so that the main contact of the AC contactor moves to protect the load from phase failure, and emits an audible and visual alarm for power failure. In manual or automatic start, you must first confirm that the outer lead of the fire damper has been connected and relayed power before starting the fan. In the automatic state, when the fire linkage sends a signal, an audible and visual alarm will be given first, and the fan will be started at the same time.

working environment:
1. The equipment should be installed in a place with an ambient temperature of 0℃~+50℃.
2. The equipment should be installed in a place where the ambient humidity is ≤90%.
3. The equipment should be installed at an altitude ≤ 2000m.
4. The equipment should be installed in a place without electromagnetic interference equipment (welding machines, high-frequency signal generating equipment, etc.).
5. The equipment should be installed in a place without explosive dust or corrosive gas.
6. There is no door on the back of the equipment box, and the distance between the installation position and the wall (or other boxes) should be ≥ 200 mm.
7. The left and right sides of the equipment box can be close to other boxes, but the distance from the wall should be maintained ≥ 200mm.
8. The distance between the front of the equipment box and the wall (or other box) should be enough to allow the cabinet door to open 90° freely.
9. The equipment box should be installed vertically on the designated ground, with the inclination around the box ≤ 10°.
