Electric strikes are a product of a growing access control industry. They are traditionally used in conjunction with various access control devices to provide limited access, traffic control, and the convenience of remote operation.
Electric strikes can be used with many latch bolt locksets by replacing the typical lock strike faceplate with an electromechanical strike assembly. Electric strikes are generally low-voltage devices that use a solenoid to manipulate the moveable keeper, or gate. Like a fixed strike, the electric strike releases and latches even with the latch bolt in an extended position. Mechanical keys are not necessary in the operation of electric strike locks. They can, however, be used to override the access system.
An electric strike is used as the pivotal piece of locking hardware for an opening. When used with an access control system, door and frame, the electric strike is the physical control that keeps the opening secure. An access system normally provides a set of dry contacts and/or power to activate the electric strike when a valid card or code read is detected.
There are over 100 types of electric strikes available on the market, varying in design to accommodate numerous types of locksets and ranging in price from $30 to $300. It is not uncommon for corners to be cut on securing the door after making a large investment on an elaborate access system. It is important to not make that mistake.
When you are using the existing door hardware, you should choose an electric strike that will perform the same function as the strike plate supplied with the lock. To properly match the two, you need to know 5 basic principles:
- Understand the type of bolt or bolts on the lock.
- Decide whether to use a mortised electric strike or a surface mounted electric strike, based on the type of hardware on the door.
- Choose the electric strike with the correct cavity depth to accommodate the lock.
- Make sure the center lines of the lock and electric strike line up properly based on the type of lock.
- Finally, consider the voltage you will use for the electric strike. AC strikes “buzz” while the DC strikes are silent or have a faint click. A DC strike will also allow you to keep the door in an “unlock” mode if necessary.
This should be enough information to get you started in the right direction for choosing whether or not the electric strikes are a good option for you. For a more in-depth guide and installation instructions, please contact Card Lock™ Company at 1-800-847-9761.
