Building video intercom system installation steps and points 1: equipment box installation
(1) The installation position and height of the equipment box should meet the design requirements. When there is no design requirement, it should be installed in a relatively concealed or safe place. The bottom margin should be 1.4m from the ground.
(2) When mounting, it should be fixed according to the design of the position plate, and the box should be horizontal without tilting.
(3) When concealing, the box should be close to the surface of the building. It is strictly forbidden to weld the box to the pre-embedded tube by electric welding or gas welding. The box body is locked with a lock.
Building video intercom system installation steps and points two: equipment installation
(1) The power box is usually installed on the inner wall of the anti-theft iron door. It should not be too far away from the electric control lock, generally within 8m. Do not reverse or sideways when the power supply is working properly.
(2) Installation of the door host. The door host is usually embedded in the security door or the wall host embedded box. The bottom margin of the host should not be higher than 1.5m, and the operation panel should be facing the visitor and easy to operate. The installation should be firm and reliable, and the effective viewing angle of the camera lens should be guaranteed.
When the outdoor intercom door is installed. To prevent rain from entering the host and the wall, the gap should be blocked with glass glue. The height of the main unit is 1.5m from the ground.
(3) Indoor unit installation. The indoor unit is generally installed on the inner wall of the doorway. The height of the installation center is 1.3-1.5m from the ground. The installation should be firm and reliable, and the installation should be straight and not inclined.
(4) The bamboo-based machine of the networked (visual) intercom system should be installed in the monitoring center or in the duty room of the community, and the installation should be firm and reliable.
Building video intercom system installation steps and points three: equipment wiring
(1) Before wiring, check the insulation between the wires and the ground to the ground that has been laid. After passing the test, the cable can be terminated according to the equipment wiring diagram.
(2) If the intercom host uses special joints and cables to connect, the crimping should be firm and reliable, and the terminals should be numbered according to the drawings. The equipment and cable shielding layer should be crimped to the protective ground wire. The grounding resistance should meet the design requirements. Share from Chico Technology.
1. Building intercom system engineering construction requirements
(1) Install the door host at a good visual level. The recommended height is 150cm (camera height).
(2) The intercom system should not be installed in places where the sun is directly exposed to sunlight, high temperature, snow frost, chemical corrosion and excessive dust.
(3) All networked cabling should generally adopt double-shielded super five-type lines, and the shield layer should be metal braided mesh.
(4) The shielding layer should be connected to all shielding layers of the system and grounded.
(5) The networking wiring is preferably connected in series. The wiring pipe should be iron pipe as much as possible, and both ends of the iron pipe should be well grounded. It should be kept at a distance of more than 50cm from strong electric cables (such as AC 220V, elevator line, cable TV line, etc.) to improve anti-interference and lightning protection.
(6) For the stability of the system and the convenience of future maintenance, the wire ends of all the networked wires should not be placed in the pipe or easily immersed in water. The joints should be soldered and wrapped with heat-shrinkable pipes and waterproof and moisture-proof. .
(7) The connection drip line should be considered at the entrance of the host wiring.
(8) Do not install in a place where the background hum is greater than 70dB, otherwise the noise of the indoor unit receiver may be relatively large.
(9) It is strictly forbidden to operate during the installation process.
(10) After all the connections are connected, it can be checked if the installation is correct.
(11) If there is any abnormality during power-on, immediately turn off the power until the fault is eliminated.
(12) If the system is not normal, please check the section after power off. If the cause of the fault is not ascertained, please inform the agent dealer or the after-sales service department of the manufacturer, and cut the unit to repair or replace the components to cause system damage.
(13) The IC card or ID card used for the first time with the host with access control must be registered by the management center before being used.
2. Building intercom system pipeline construction requirements
(1) The installation of the cable shall comply with the IEEE electrical installation cable laying specifications and relevant national and industrial regulations.
(2) Products that meet the requirements should be selected according to the requirements of the selected import and export product manufacturers.
(3) The indoor wiring is not only required to be reliable and safe, but also to make the line layout reasonable, tidy and securely installed.
(4) The rated voltage of the wire used shall not be greater than the working voltage of the line; the insulation of the wire shall comply with the installation method of the line and the environmental conditions of the laying and the mechanical strength of the wire.
(5) Wiring should be as close as possible to avoid wires. If the joint is not available, the joint must be crimped or welded. Mechanical connections should not be taken at the wire connections and branches.
(6) The wiring should be installed horizontally or vertically in the building. The wiring should be sleeved (plastic or iron water pipes, according to the technical requirements of the indoor wiring), the ceiling can be equipped with hose or PVC pipe, but it needs to be fixed and beautiful.
(7) The signal line cannot be parallel to the high-power power line, and it cannot be worn in the same tube. If the introduction of Century Star is due to environmental constraints, it is necessary to walk parallel lines, and then stay away from 50cm.
(8) The AC power supply should be routed separately. It should not be placed in the same pipe as the signal cable and the low-voltage DC power cable. The installation of the AC power cable should meet the electrical installation requirements.
(9) Controlling the host-to-ceiling wiring requires that the casing be buried in the wall or protected by an iron water pipe to improve the destructive performance of the anti-theft system.
(10) When wiring, distinguish between power lines, communication lines, and signal lines. The wire diameter of the power cord is thick enough to use multi-strand wire; the signal wire and the communication wire adopt five or six types of twisted pair wires, and the shielded twisted pair wire can be used when the environment requirement is high. Pay attention to the strong and weak wires when wiring.
