Tech Tips: Versatile Electric Strikes

June 1, 2017
Before selecting the best strike for your application, conduct a detailed site survey, verifying space for the strike body, power availability, and door, lock and frame condition

Today’s professional security installer has a wide assortment of options available when specifying electrical locking hardware. This is very different than during the dawn of the electronic access control era.

A number of factors will determine which locking solution you specify, and the starting point is a detailed site survey and review of the budget allotted to the project, how the system is expected to operate, and the exact nature of the building or business into which the electric lock will be placed.

Here are a few tips:

  • Check for room behind the existing strike plate to be sure an electric strike body will fit. This is critical on storefronts where there may be extrusions and the edge of the glass in the way, or frame set into poured concrete cinder block construction.
  • Check for wiring access to the strike’s location. Planning will be required for providing line voltage for the power supply and for running the low voltage lines from the power supply to the electric strike.
  • Remember that passage function and entry function locksets are not suitable for use with an electric strike.
  • Determine if the door is a fire door assembly. You are limited to the modifications you can perform on the door and frame without affecting the door integrity and a fire protective.
  • Be certain the strike is designed for the lock. Latch length is critical, and also if it is a mortise lock, you need to determine if a deadbolt will override the electric strike, or if the electric strike will permit opening the door when the strike is actuated.
  • Figure out whether you want failsafe or failsecure operation, and provide the proper power supply for the strike.
  • Be sure the door is in otherwise proper working condition; adding electrical hardware will not solve other issues such as sagging, damaged hinges, or inoperative or non-existent door closer.
  • If the door is subject to backpressure from air conditioners or heating systems, select an electric strike which will tolerate preloading.
