Electric strikes are an access control program used to secure doors and pedestrian gates. An electric strike’s elevated surface can, upon command, revolve out of the way, permitting the entry to be pushed open without a retracted latch. Electric strikes can nonetheless turn a knob to enable exiting from the secured location. Electric strikes may be fail-safe or fail secure. Fail-safe devices are unlocked when power is off.
