Common Faults of Magnetic Locks and Their Solutions 

The electromagnetic lock operates based on the principle of an electromagnet. Once powered on, a very small current will generate a strong magnetic force, forming a magnetic lock. After the access control system identifies the correct person, the magnetic lock will lose its magnetic force and then be able to be opened. 

Usually, after being used for a long time, magnetic locks may encounter some problems due to various reasons. So, what should we do when facing these malfunctions? 

The magnetic lock makes a loud noise when it is closed. 

a. Check if the rubber gasket is properly sealed; 

Check the ends of the steel plate and see if the screws are loose. 

Check whether the distance between the magnetic lock body and the suction cup is appropriate. 

2. Iron has poor absorption properties. 

a. Check whether the 'power and voltage' of the power supply have decreased to 1A/12V/24V output; 

b. Check the surface of the magnet for any impurities (such as dust, rust, foreign objects, etc.). 

3. The magnetic lock plate needs to be adjusted frequently. 

Check whether the pins of the iron plate have been properly inserted. 

Check if the iron plate is equipped with rubber pads. 

It is recommended that customers use the 'screw fixator' on the screws. 

The iron plate felt a slight vibration when it was inhaling. 

(a) Check whether the main surface of the lock body is fully engaged with the iron plate without any foreign objects. Or loosen the iron plate slightly and try again. 

Check whether the voltage and current are sufficient. 

Invalid delay function. 

The 'delay adjustment' of the magnetic lock starts timing after the device is powered off, rather than starting timing immediately after the power-off. 

The magnetic lock has delay times of 0, 3, 6, and 9 seconds. Please check if the setting is set to 9 seconds. 

After being powered on, the light-emitting diode emits a faint light that cannot be absorbed. 

Check whether the voltage of the electromagnetic lock is sufficient (it should be 1A current / 12V voltage). 

After turning on the power, the red LED light came on, but the green light did not. 

Perhaps the sensing component of the magnetic lock has been damaged and needs to be replaced. 

The double-door magnetic lock cannot be recharged after being used for a period of time. 

The magnetic lock of the double-door lock consumes a considerable amount of power. Check whether the power supply is sufficient (whether it can meet the required current and voltage, or there is any wire loss). 

The configuration controller is not functioning properly. 

Please check if the Output contact of the controller is set correctly.
