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

Posted on

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.

Product introduction

Scrap aluminum shredding machine is also known as aluminum alloy shredding machine, is a rolling knife shaft through the generation of shear force, will be a large number of scrap aluminum material shredding machine equipment to a certain size, with electrostatic and specific gravity separator will be completely separated from aluminum, suitable for a variety of aluminum materials crushing separation screening operations.

Principle of equipment

Aluminium scrap shredding machine (aluminium alloy shredding machine) with eddy current separator, screening machine, magnetic separator, which can effectively separate the aluminum, iron, paint will be all kinds of scrap aluminum alloy pieces, magnetic separation, screening, cleaning processing, non-metallic impurities removing metal impurities and waste, realize the separation of waste aluminum and recycling, sorting rate can reach 96-99%, maximum get pure aluminum into the next phase of smelting recovery, the aluminium scrap shredding machine effectively provide aluminium scrap recycling efficiency, reduce waste aluminum transportation cost, storage cost.

Characteristics of the equipment

1. The blade is made of cold die steel with good strength, high toughness and high cutting performance. The blade has four cutting edges and can be rotated 90° after wear for continued use.

2. Hydraulic forced feeding, stable and adjustable speed, large and even propulsion force

3. Hard tooth surface reducer, high transmission efficiency, strong bearing capacity and low noise.

4. Blade thickness: 20mm (customized according to customer needs)

5. Scrap aluminum shredder (aluminum alloy shredder) can be easily replaced after the tool damage or wear.

Equipment maintenance:

1. Fix the equipment on the foundation, start the air machine first, and check whether the parts are deformed or damaged during transportation.

2. During operation, the bearing and reducer shall be filled with quantitative lubricating oil. During normal operation, the material conveyor shall be cut out first, and the equipment shall be moved.

3. Before starting up each shift, check the lubrication of the bearing. At the end of each shift, clean the equipment carefully.

Applicable materials:

Is suitable for the aluminium scrap, such as aluminum, aluminum alloy, aluminum, aluminum plate, aluminum scrap, aluminum scrap, aluminum, aluminum wire, aluminum alloy, aluminum cans, aluminum scraps, aluminum casting, aluminum, aluminum tubes, scrap aluminium wire, aluminum mold, stamping aluminum, aluminum scrap, mechanical raw aluminum, aluminum foil, aluminum wire, PS version, aluminium scrap, scrap aluminum, cooked aluminum, aluminum slag, scrap aluminum ash, waste aluminum, waste aluminum, scrap aluminum mold, waste PS plate, such as aluminum scrap aluminium wire materials, smashing into a state of separation, the corresponding sorting equipment for aluminum separation, separation rate can reach 96-99%.
