Surface mount electric strikes according having a housing with an opening for a door latch bolt. First and second opposing latches are movably mounted to the housing and operable to open or block the lack bolt opening. First and second keepers can be in the housing each of which is arranged to cooperate with a respective one of the first and second opposing latches to block or not movement of its latch. A single actuating device is also in the housing and is controlled by an electrical signal. It is arranged to operate on the first and second keepers and is moveable in the housing between two positions. One or more mode control screws can be included that engages the actuating device through the housing and are movable between at least two screw positions. The movement of the screw causing movement of the actuating device between its device positions, wherein one of the positions results in operation of the strike in fail-safe mode, and the other of the positions results in operation of the strike in fail-secure mode.

An electric strike having two independent keepers. The strike works with a lockset having both a deadbolt and a mortise lock bolt. A latch adapted to engage a deadbolt is provided with a solenoid to lock or unlock the latch. Another latch adapted to engage a mortise lock bolt is provided with a solenoid to lock or unlock the latch. Each latch is independently operable.

An inline motorized lock drive is mountable within a lock housing to drive a sliding locking element between a locked and unlocked position. The lock drive includes a reversible motor having a shaft with an augur thereon to drive a lock spring, which drives the locking element. The sliding motion of the locking element is axially aligned with the motor axis to substantially reduce friction. The lock drive is preferably modular and emulates a solenoid lock drive with a control circuit. The control circuit is connected to drive the motor is switchable to default to a locked position or an unlocked position and emulate a fail safe or a fail secure type solenoid lock drive. The control circuit operates on 12 or 24 volts to replace solenoid locks of either voltage and stores power when power is applied, then uses the stored power to return the lock drive to the selected default state when power is removed.

An apparatus and method is disclosed for electronic locks with a selectable power off function. The electronic lock includes an electronic controller disposed within a lock housing and operable to control a state of the lock between locked and unlocked positions. An electronic actuator electrically coupled to the controller is movable between first and second positions corresponding to a locked position and an unlocked position of the lock, respectively. The electronic lock further includes at least one electrical energy storage device and a selector switch coupled to the controller to define a desired state of the lock between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.

An access control system including a locking assembly and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, an energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between a locked state and an unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and is configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device. The locking assembly may further include a selectable power off function and a controller disposed within a lock housing and operable to control a state of the locking assembly between locked and unlocked positions. The electromechanical actuator is movable between first and second positions corresponding to the locked and unlocked positions, respectively. The locking assembly may further include a selector switch coupled to the controller to define a desired state of the locking assembly between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.

Lock device (1) which incorporates a closure assembly (2) that can move between an open position and a closed position, a locking device to lock said closure assembly (2) in the closed position, a first actuator (3, 31) and a second actuator (4, 41), both the first actuator (3, 31) and the second actuator (4, 41) having a locked position, in which a locking or retention action is applied, and an unlocked position, both the first and the second actuators having respective control devices which allow orders to be given to change the position of each respective actuator, wherein the first actuator and the second actuator are arranged in such a way that unlocking the locking device requires that both control devices place their respective actuator in the unlocked position.

A locking device is disclosed having (a) a tubular housing having a frontal end and a distal end; (b) a latch movable between a first position protruding from the frontal end of the housing and a second position wherein the latch is retracted in the housing; and (c) an electrically driven drive device for moving the latch between the first and second positions. The locking device further includes a deactivation mechanism provided in the housing and allowing movement of the drive device or at least part thereof from an active position wherein the drive device is enabled to move the latch between the first and second position and an inactive position wherein the latch is retracted in the housing irrespective of its movement by the electrical drive device.

An electric door strike assembly includes a housing and at least one keeper arm. The housing has an opening for admission and retraction of a door latch. The at least one keeper arm has a latch portion and is mounted on the housing. The at least one keeper arm is movable between a closed position, where the opening is occluded by the latch portion, and an open position, where the door latch may be released from the opening. The latch portion may include a bifurcated member having inside and outside legs arranged in spaced parallel relation so as to define a gap therebetween. The gap is configured to receive a latch plate of an interlocking latch mechanism when the at least one keeper arm is in the closed position.
