First, the indoor wiring technology

 

Indoor wiring not only requires safe and reliable, but also to make the circuit layout is reasonable, neat, strong installation. The technical requirements are as follows:

 

Use the wire, the rated voltage should be greater than the operating voltage of the line; wire insulation should be consistent with the installation of the line and laying the environmental conditions. The cross-sectional area of the wire should be able to meet the requirements of power supply and mechanical strength.

 

Wiring should try to avoid the wire with a connector. Unless the connector is not available, the joints must be used pressure line or welding. Wire connections and branches should not be mechanically wired to be installed in the building to maintain horizontal or vertical. Wiring should be combined with casing protection (plastic or hot metal pipe, according to the technical requirements of indoor wiring matching), ceiling pipe available metal hose, but need to be fixed and beautiful. Signal lines can not be parallel to high-power lines of power, and can not be worn in the same tube. If the environment is limited, to parallel alignment, will have to stay away from 50CM or more.

 

The AC power supply of the alarm control box should be routed separately and can not be worn in the same tube as the signal line and the low voltage DC power cord. The AC power cord should be installed in accordance with the electrical installation standard. Alarm control box to the ceiling of the requirements of the casing embedded in the wall or with a metal pipe to be protected to improve the anti-theft system to improve the anti-damage performance.

 

Second, the indoor piping technical requirements

 

Wire and cable wiring with clear and two with the two, Ming piping requirements horizontal flat, neat and beautiful. Dark piping requirements of the pipeline is short, smooth, less elbow. The choice of pipe, according to the design drawings to select the type and specifications of the pipe, if not specified, according to the total length of the wire through the wire (even the skin), do not exceed the pipe hole cross-sectional area of 70% of the limits of matching.

 

In order to facilitate the pipe threading and maintenance, in the pipe length exceeds the following values, the middle should be installed junction box or cable box, the location should be easy to thread.

 

(1), the pipe length of each more than 40 meters, no bending;

 

(2), the length of each more than 25 meters, there is a bend;

 

(3), the length of each more than 15 meters, there are two bends;

 

(4), the length of each more than 10 meters, there are three bends;

 

The wire tube is fixed and the wire tube should be fixed in the corner or at a straight line distance of more than 1.5 m.

 

The bending radius of the wire harness shall comply with the provisions of the bending radius of the cable. Where there is trachoma, cracks and large deformation of the pipe is prohibited to use in wiring works. The connection of the wire tube should be connected with a sleeve or buckle.

 

Vertical laying of the pipe, according to the size of the cross-section into the wire, at every 10-20 meters, add a fixed threading junction box, with a wire clip to fix the wire in the box, the thicker wire, between fixed points The shorter the distance.

 

Do not enter the box (box) within the vertical nozzle, through the wire, the nozzle should be sealed.

 

The junction box or junction box should be fixed not less than three screws.

 

The connection between the connection box and the pipe should be combed. The junction box or junction box should be capped. The branch of the line should be added to the junction box.

 

Third, the installation of space detectors technical requirements

 

The installation of the space detectors shall be in accordance with the technical specifications.

 

The installation of the detector should ensure a 24-hour tamper function to prevent man-made damage.

 

The location of the detector should be avoided by small animals such as rats crawling close.

 

The detector should be mounted on a rugged, hard-to-vibrate wall with 2-3 screws.

 

The detector should be installed so that there should be no obstructions in the front detection range.

 

Fourth, the magnetic switch installation technology

 

The installation of the magnetron switch should be solid, neat, beautiful, as far as possible in the door inside, to prevent damage. The distance between the fixed and active components of the magnetron switch should be less than the following:

 

(1), wooden door magnetic switch and iron gate magnetic switch should be less than 5mm.

 

(2), roll gate magnetic switch should be less than 20mm.

 

Fifth, the control box installation technology

 

The installation of the control box shall comply with the requirements of the technical specification.

 

Control box should be fixed not less than three screws, to ensure a solid. The location of the choice to conceal, for the prevention of damage, control box operation to remote control switch, remote control switch away from the control box to install, have a tamper function, and use the door to be protected, remote control switch with a password switch, Three times the password triggers the alarm function.

 

Control box should be installed tamper function, should be demolished at any time should be the police.

 

The AC power of the control box should be introduced without the switch. If the switch is to be used, it should be installed in the control box. The AC power cord should be pipelined separately and should not be worn in the same tube as other wires.

 

Control box of the lead, from the control box to the greenhouse for a section to be protected with iron pipe, iron pipe and control box to use double nuts to connect.

 

Power box installation is higher than the ground more than 2 meters, to be strong, beautiful, to ensure safety.

 

Six, pre-sale service

 

Pre-sale need to provide relevant technical information, such as system introduction, system manual, etc., and a brief introduction. For the specific circumstances of the project, to provide the necessary advisory services, to provide anti-theft concept of goods related to consultancy services. Analysis of system configuration, feasibility, and economic analysis to provide valuable constructive comments. Through the overall planning and design and installation of the scene of the environment survey, the most economical and reasonable optimization program.

 

Seven, the sale of services
