  • Make sure the electromagnet and armature plates are properly aligned.
  • Make sure the contact surfaces of the electromagnet and armature plates are clean and free from rust.
  • Check the power leads with a meter, and make sure 12VDC or 24VDC is present.
  • Make sure the rubber washer is installed and free from damage. 

Delay in door releasing 
  • The electromagnet is fitted with a metal oxide varistor to prevent interference, so do not install a second diode.
  • Ensure that the control device is connected between the power source and the positive terminal of the lock
