Features:
1. This equipment consists of basic units such as main circuit, control circuit, operation and indication parts. The main circuit supplies power to the equipment; the control circuit controls the controlled equipment and receives feedback signals from the controlled equipment; the operation and indication part indicates the working status of the equipment and receives the operator's operation and setting instructions.
2. The working principle of this equipment is as follows: After receiving the on-site manual control signal or the fire joint control signal from the fire linkage controller, this equipment processes and converts the signal to form the next level control signal and transmits the signal to the controlled The device sends; at the same time, it controls the main circuit to turn on/off the power of the controlled device, thereby completing the function of controlling the start/stop of the controlled device. In addition, this equipment can also transmit the working status information of the controlled equipment to the upper level fire linkage control system, and send out instruction signals to display the equipment and the controlled equipment, such as: power signal, manual/automatic working status signal of the equipment , the status signal of the controlled equipment is logged in, thereby completing the information transmission and indication functions.

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 cabinet, and the distance between the installation position and the wall (or other cabinets) should be ≥ 200 mm.
7. The left and right sides of the equipment cabinet can be close to other cabinets, and the distance from the wall should be maintained ≥ 200mm.
8. The distance between the front of the equipment cabinet and the wall (or other cabinet) should be enough to allow the cabinet door to open 90° freely.
9. The equipment cabinet should be installed vertically on the designated ground, with the inclination around the cabinet ≤ 10°.
