An Electric Strike is an access control device used to lock and release doors. Electric Strikes are installed in or on the door frame and work in conjunction with mechanical door locks, on the principle of electronically controlling the rotation of the keeper. This allows doors to be opened without manual retraction of the mechanical door lock.
Electric Strikes generally come in two basic field-selectable configurations:
Power To Release (PTR) In this configuration, applying power to the strike will cause it to unlock. The strike will remain locked in a power failure. However most access control systems are provided with backup batteries.
Power To Lock (PTL) In this configuration, applying power to the strike will cause it to lock. If there is a power failure or fire alarm condition the door will open merely by being pushed/pulled.
