1. The AC power supply for the wiring of the parking lot system should be routed separately. It cannot be used in the same pipe as the signal line and the low-voltage DC power line. Because the parking lot management toll booths are generally installed with air-conditioning, Trident recommends that the AC power supply The size of the line should be sufficient.
Second, the signal cable of the parking lot system control main board can not be laid in parallel with the AC power line, and it should be avoided in a PVC pipe as much as possible. If it is limited by the environment, you must keep away from more than 50cm in parallel.
3. When the entrance to the parking lot is at a slope, the control cabinet should be installed on a flat road surface or on a concrete pouring platform. Dreidtech recommends avoiding the occurrence of half ramps when the vehicle is swiped.
4. During the wiring of the parking lot system, the distance between each equipment should be properly adjusted according to the site conditions. If there is no equipment in the system, the wire required for the equipment does not need to be laid, and the size and placement of the entrance and exit control machines, exit gates, and entrance and exit cameras are not required. The same position, the same size of the floor coil.
Fifth, parking lot wiring All external devices connected to the head can not be too long, so as to avoid exposure to short-circuit phenomenon, the parking lot system must be marked when the cable is marked, to facilitate the future installation, commissioning and maintenance.
6. Before the wiring in the parking lot, brush the hole of the pipe first. When passing the cable, grease or talcum powder should be applied. The cable that enters the nozzle should be kept straight, and measures such as moisture-proof and anti-corrosion should be taken.
VII. When wiring the parking lot system, avoid joints on the wires. Unless joints are available, their joints must be crimped or welded and waterproofed. Wire connections and branches should not be subjected to mechanical forces.
