  • Unmount the strike and check that the two wires are connected properly.
  • Ensure the wires are 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.
