Entrance guard system wiring installation note

2023-10-04 00:00:00

entrance guard system to install the equipment is less, generally is the controller, card reader, electric lock, door bell, etc., looks installation is very simple, actually otherwise, the wiring alone need to pay attention to many places, a little bit careless, omissions, may appear all kinds of small problems, inconvenience for later use.We do many years of experience in the installation of a summary, hope will be helpful to you.

a, 485 controller wiring

construction wiring according to specification is the basic requirement for all installation work, but really very little installation personnel, convenience, not strictly enforced.The following wiring specification must be need to be aware of.

1. All lines of communication must use twisted-pair cable or Ethernet cable, with better shielding.
2. The communication circuit wiring cannot use parallel lines, even if the line is shorter, also do not covet convenient use of parallel lines, because of the parallel lines is the biggest hidden trouble later communication problems.
3. The communication routes do not split or in parallel, must be in series.Will not produce interference, the impact of communication.

2, controller and electric lock link

if the controller is directly connect with electric lock the way (not by external power supply connected again), pay attention to the wiring distance, if the distance is within 50 meters, must be used cross-sectional area is 1.0 square millimeter of the power cord;More than 50 meters, must be bold wire, can use the two turned into a shares.If you want to install two locks on the door, you must walk the line, not collinear.Finally speak a little, some installation personnel covet convenient, direct use cables to connect the electric lock, this kind of practice is wrong, should not be used.

3, card reader, the connection between the

joint between card reader can’t simply screwed together with the hand, hand twist cause poor contact, you must use the welding joint is good, solid, and then wrapped in insulation cloth or heat shrinkable tube, (better heat shrink tubing).

4, wiring lines

wiring for beauty is to go as far as possible wiring, circuit also must walk, this is to prevent the mouse biting the necessary measures, if bitten by mouse is broken, is very troublesome to rewiring it difficult (because some lines, sealing the top).

5, power supply

access control card reader and the controller power consumption is small, power consumption of electric lock is larger.We summarized as follows: 5 a linear power band can be at most four conventional electric lock controller + 4 card reader + 1.5 a maximum of switch power supply with the conventional electric lock controller + 8 card reader + 1.In order to make the power supply, it is best to use the power of the original, need to outsourcing also suggest to buy brand.
