Selecting Fail-Safe or Fail-Secure Operation:
Troubleshooting:
Electric strike does not activate.
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.
Door does not open when the
electric strike is activated.
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.
Use DC power supply instead of AC power.
