Connect the strike to a DC power supply.  

Troubleshooting: 

Door does not open when the 
electric strike is activated 

 

Dismount the strike and check that the wiring connector is 
connected properly.  

 

Ensure the wiring connector is connected to a 12 or 24VDC source. 

 

Use a multimeter to test that the strike is receiving the proper 
voltage and amperage. If it is not, it may be necessary to use 
heavier gauge wires, or increase the output of the power supply. 

 

Make sure the activation device (keypad or push-button switch) is 
working properly. 

 

Electric strike does not activate 

 

Check that the door latch is operating properly, and replace  
if necessary. 

 

The position of the electric strike may need to be adjusted by 
moving it or adding washers or shims.  

Strike makes a buzzing sound
