Reversible Electric Door Strike, Symmetric

The SECO-LARM Reversible Electric Door Strikes are an ideal way to adapt cylindrical lock sets to an electronic access-controlled locking system. The strikes come in two varieties: asymmetric and symmetric. Both models come with a reversible faceplate for right-hand or left-hand doors and are fail-secure operation

FAQs

  1. Check that the door latch is operating properly, and replace if necessary.
  2. The position of the electric strike may need to be adjusted by moving it or adding washers or shims.
  1. Unmount the strike and check that the two wires are connected properly.
  2. Ensure the wires are connected to a 12 or 24VDC source.
  3. 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.
  4. Make sure the activation device (keypad or push-button switch) is working properly.

Use DC power supply instead of AC power
