A configurable electrical connector key for connecting an electronic door lock to an external unit, such as a lock monitoring or control system, includes a connector key housing shaped to engage the electronic door lock and a configurable circuit mounted within the connector key housing that makes a configured interconnection between selected components within the door lock and the external unit. The combination of an electrical connector key and an electronic door lock and a system and method including multiple differently configured electrical connector keys and one or more standardized electronic door locks allow selected sensors and functions of the door lock to be enabled by selecting an appropriately configured electrical connector key.

A latch and lock assembly for a double door arrangement having a first door and a second door, in use, being pivotally mounted for movement about either a common pivot axis or closely adjacent parallel pivot axis to a door frame. The latch and lock assembly include: a releasably latching mechanism operatively adapted to releasably latch at least one of the first and second doors to the door frame; a releasable connection mechanism operatively adapted to releasably connect the first door to the second door; and an operating system operatively adapted to control both the latching mechanism and the connection mechanism. The operating system includes an electrical drive operable by an electric power source to drive an actuator that operates the releasable latching mechanism, the releasable connection mechanism, or both.

An intelligent door lock system is provided with a push notification. A sensor is configured to be coupled to a drive shaft of a lock. The position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock. An engine with a memory is coupled to the positioning sensing device. The engine and an energy source are coupled to the circuit. A push notification is provided to a dwelling user when a lock of the intelligent door lock system is manually opened.

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 electromechanical lock which is configured to provide a mechanical latch holdback feature, whereby a key is useable to retract a latch of the lock, the key can be removed, and the latch remains mechanically held back. The held back latch is remotely releasable. As such, a correctional officer can use his key to mechanically hold back the latch, such that the lock remains open. Subsequently, a control signal can be sent from a remote location causing the latch to be released and extended, such that the lock locks. This ability to remotely override the mechanical latch holdback is useful in a correctional facilityfor example, when the mechanical latch holdback has been engaged for cell doors and an emergency situation arises where a quick remote lockdown may be necessary, instead of having to perform the time-consuming task of re-locking the doors one-by-one, locally by key.

The disclosure discloses a door lock including a locking mechanism, a power interface, a main control board, an environmental information collection device and a power supply management device, where the locking mechanism, power interface and power supply management device are respectively connected with the main control board, the environmental information collection device connected with the power supply management device, the environmental information collection device configured to collect and transmit environmental information on the surrounding of the door lock to the power supply management device; the power supply management device configured to carry out processing according to the environmental information and output a power supply mode matched with the environmental information to the main control board; and the power interface configured to execute an operation related to the power supply mode matched with the environmental information according to a power supply instruction from the main control board.

A configurable electrical connector key for connecting an electronic door lock to an external unit, such as a lock monitoring or control system, includes a connector key housing shaped to engage the electronic door lock and a configurable circuit mounted within the connector key housing that makes a configured interconnection between selected components within the door lock and the external unit. The combination of an electrical connector key and an electronic door lock and a system and method including multiple differently configured electrical connector keys and one or more standardized electronic door locks allow selected sensors and functions of the door lock to enabled by selecting an appropriately configured electrical connector key.

A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

A latch assembly comprising: a latch operative to adopt a latched condition and an unlatched condition; a magnet imparting a magnetic field; a sensor adapted to sense the magnetic field; the latch, magnet and sensor being configured such that a change in the condition of the latch effects a variance in the magnetic field sensed by the sensor such that the sensor is able to distinguish between the latched condition and the unlatched condition.

An access control device including an electromagnetic lock module for selectively locking and unlocking a door in a door frame is provided. The access control device provides a lower profiled electromagnetic lock module to improve the aesthetics and functionality of the module, supports and integrates modern accessories such as CCTV, CCD cameras, passive motion detection with automatic background correction, digital notification display, automatic source voltage selection, door and lock status indicators, and ease of installation. The present invention further provides components and circuitry to enable connection of the electromagnetic control module to 12 or 24 volts DC or to an unfiltered rectified AC power supply.
