An electric strike for a door frame, comprising: a body; a keeper moveably attached to the body for selectively 5 retaining a latch bolt on a door; a blocking element movable between a blocking position in which the blocking element locks the keeper to prevent a latch from being moved past the keeper, and an unblocking position in which the blocking element unlocks the keeper to allow the latch 10 to move past the keeper; an electronically controlled electric actuator for moving the blocking element between the blocking position and the unblocking position; and an override mechanism to override the electric actuator.

An anti-barricading thumb turn assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading thumb turn assembly includes a spindle connected to a thumb turn with a biasing member on one side of the lockset. The lockset is also operable by a key from the other side of the door to lock and unlock the door. Under normal operation, the spindle and thumb turn rotate as the bolt is locked and unlocked. In a barricading situation in which the thumb turn is held to attempt to attempt to prevent the spindle from rotating, the biasing member allows the spindle to rotate relative to the thumb turn upon application of sufficient force through rotation of the key to overcome the biasing force and unlock the bolt even if the thumb turn is held stationary.

Systems, apparatuses, and methods of releasing doors that are locked in a closed position. The apparatus may include a follower assembly movably attached to a locking member that moves between a secured position and an unsecured position. The follower assembly may include a first locking element. The apparatus may additionally include a second locking element configured to move between a locking position in which the second locking element engages the first locking element, and an unlocking position in which the second locking element is spaced from the first locking element. The apparatus may further include a support assembly configured to move between a proximal position in which the support assembly supports the second locking element in the locking position, and a distal position in which the support assembly allows the second locking element to move from the locking position to the unlocking position.

A method including placing a first adhesive on a first surface of a strike plate, wherein the strike plate includes a pocket extending into a second surface of the strike plate opposite the first surface of the strike plate. The method further includes placing a second adhesive on a first surface of a lock module, wherein the lock module includes a bolt operable to extend beyond a second surface of the lock module. The method also includes aligning the pocket with the bolt such that the bolt is operable to extend into the pocket, and with the pocket and the bolt aligned with one another, releasably joining the strike plate and the lock module with a releasable coupler, thereby forming an aligned locking assembly.

An exemplary apparatus includes a housing, a lock mechanism mounted to the housing, an electromechanical driver, a first override mechanism, and a second override mechanism. The electromechanical driver is mounted to the housing and is operable to unlock the lock mechanism. The first override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The second override mechanism is movably mounted to the housing and is operable to unlock the lock mechanism. The apparatus has a first configuration in which a lock cylinder is engaged with the first override mechanism such that actuation of the lock cylinder unlocks the lock mechanism. The apparatus has a second configuration in which the lock cylinder is engaged with the second override mechanism such that actuation of the lock cylinder unlocks the lock mechanism.

A bolting mechanism includes bolt members driven between extended and retracted configurations, a first drive train to couple motion of a handle to the members to drive them between configurations, a primary deadbolt mechanism to prevent the bolt members from being driven between configurations when the mechanism is in a locked state, the mechanism includes a fail-secure actuator that prevents the bolt members from being driven between configurations in case of power loss, a second drive train to couple motion of a second handle to the bolt members to drive them between configurations, the second drive to override the mechanism to drive the bolt members between configurations even when the mechanism is in the locked state, and a secondary deadbolt mechanism arranged to prevent the bolt members from being driven between configurations when the secondary deadbolt mechanism is in a locked state.

A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

An anti-barricading turn hub assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading turn hub assembly includes a spindle connected to a thumb turn on one side of the lock. The spindle is releasably engaged to a turn hub that is operable by the key from the other side of the door. Under normal operation, the spindle and turn hub rotate together to lock and unlock the bolt. In a barricading situation in which the thumb turn is held to prevent the turn hub assembly from rotating, the turn hub disengages from the spindle upon application of sufficient force through rotation of the key, and the disengaged turn hub can be rotated to unlock the bolt even if the thumb turn is held to keep the spindle from rotating.

A modular surface mounted electric strike system is provided. The system comprises a universal base plate configured to be mounted to a door frame and including first and second mounting points. The system further includes an electric strike module configured to receive the door latch and includes a keeper assembly and an actuator assembly. The actuator assembly is configured for moving between a first mode for preventing the keeper assembly from moving toward an unlatched position and a second mode for permitting the keeper assembly to move toward the unlatched position. When the door latch is in a first position relative to the door frame, the electric strike module is attached to the first mounting point. When the door latch is in a second position relative to the door frame, the electric strike module is attached to the second mounting point of the universal base plate.

Systems, apparatuses, and methods of releasing doors that are locked in a closed position. The apparatus may include a follower assembly movably attached to a locking member that moves between a secured position and an unsecured position. The follower assembly may include a first locking element. The apparatus may additionally include a second locking element configured to move between a locking position in which the second locking element engages the first locking element, and an unlocking position in which the second locking element is spaced from the first locking element. The apparatus may further include a support assembly configured to move between a proximal position in which the support assembly supports the second locking element in the locking position, and a distal position in which the support assembly allows the second locking element to move from the locking position to the unlocking position.
