- 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.
