Several methods of connecting the door controller to the door magnetic and electric locks

At the Third Session of the Twelfth National People's Congress held this year, the Prime Minister Li Keqiang proposed for the first time in the government work report the formulation of the "Internet +" action plan and emphasized the need to develop "Smart City." The successful use of the access control system in intelligent building office buildings, smart residential access control, government offices, medical hospital systems, and other industries, successfully opened the "Internet +" era of access control systems. With the continuous development of mobile access control systems, especially with the continuous maturation of technologies such as Bluetooth, WIFI and NFC, mobile access control has a stable communication technology foundation.

Here are some common ways of connecting the door controller to the door magnetic and electronic control locks, and share with you.

Note: The door magnet and the lock need to be powered separately. Do not supply power to the door magnet through the access control wiring. It is very easy to open the door.

Method one :

The door controller is connected to the door magnet, the door magnet is only normally closed with two interfaces + and -, the access control NC is connected to the positive pole of the power supply, the negative pole of the power supply is connected to the magnetic cathode of the door, and the magnetic pole of the door is connected to the access com. As long as the normal formation of a loop can be connected together.

Method two :

Some magnetic interfaces have 5 interfaces: positive pole, negative pole, NC, NO, COM, gate magnetism normally closed. The access control NC connects the positive pole of the power supply, the negative pole of the power supply connects to the magnetic pole of the door, the magnetic pole of the door connects the com of the access control, the SR of the access control oscillating magnetic lock connects the NC of the lock, and the GND of the access control connects the magnetic com of the door.

Method 3 :

Normally closed lock body wiring (electric lock/mute lock), the so-called normally open lock is normally open power, can open the door under power, power off, so once the power off the door will not open.

Wiring method: First, the positive and negative poles of the power supply need to be divided into two. The positive pole of the power supply is connected to the positive pole of the electronically controlled lock and the L+, the negative pole of the power supply is connected to the negative pole of the electronically controlled lock and the com of the access control, and the L-connection of the electronically controlled lock is NO.

Magnetic door open button connection

The door open button "+" is connected to the PUSH interface of the access controller, and the door open button "-" is connected to the GND of the access controller. The switch signal does not require power supply.
