An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.

An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.

A lock module for a door in an aircraft has a lock with a blocking element and a non-self-locking drive for moving the blocking element. A blocking sensor detects a blocked position and an unblocked position of the blocking element. A control unit receives a blocking signal from the sensor and activates the drive based on the blocking signals of the blocking sensor(s). A module portion of the door leaf has at least the lock, the drive, and the blocking sensor structurally integrated therein. There is also described a door for the space with a lock module where the door leaf of the door contains the module portion, and a space of an aircraft which is closed by the door.

A door safety barricade capable of preventing an intruder from entering through a door in a classroom, a school, an office building, and the like, when the device is in an engaged, locked position and wherein the selected authorities will be automatically notified as the locking device passes by the sensor while being engaged.

A system for detecting the position of at least one moveable element of a window or door, the system comprising: at least one sensor for sensing a magnetic field, the at least one sensor being configured such that the magnetic field sensed changes as said moveable element moves; and a processor configured to receive output signals associated with the sensed magnetic field and to determine the position of said moveable element; wherein the system is configured to operate in a calibration mode and a normal mode, wherein in the calibration mode the system is configured to register at least an output value from said sensor when said moveable element is at a first predetermined position as a corresponding first reference value and wherein in the normal mode the processor means is configured to use the first reference value in determining the position of the at least one moveable element.

A shared storage cabinet and a lock thereof are disclosed. The shared storage cabinet includes a cabinet body and a lock installed on the cabinet body. The cabinet body is divided into a plurality of cells by means of a frame thereof. The cabinet lock includes a lock body, a locking piece and a locking and unlocking assembly. The lock body is laterally inserted into and fixed within the frame of the cabinet body. The locking and unlocking assembly is disposed within the lock body. One end of the locking piece is pivotally connected to one side of the lock body, while the other end of the locking piece rotates about the end thereof to achieve locking/unlocking in cooperation with the locking and unlocking assembly of another adjacent cabinet lock on the frame.

A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.

For locking industrial safety guarding, a sensor includes an inductive coil that generates a second sensing field about a second sensing field axis at a second frequency that detects advancement of a locking bolt. The sensor further includes at least two radio frequency identifier (RFID) coils that generate a first sensing field at a first frequency that detects an RFID tag. A second RFID coil of the at least two RFID coils has a second polarity reversed from a first polarity a first RFID coil of the at least two RFID coils and reduces the first sensing field at the second sensing field axis.

The present disclosure is directed to an electronic deadbolt control system including a deadbolt configured to extend or retract between a locked position and an unlocked position, respectively. An output shaft connected between a final gear and the deadbolt is configured to transmit an actuation force to the deadbolt from an electric motor. A first magnet and a second magnet are associated with the final gear to define a home position for either a left hand deadbolt or a right hand deadbolt. A cam is positioned on the output shaft to engage with a switch such that, in combination with a threshold current motor output, the control system determines whether the deadbolt is in an extended position or a retracted position. A thumb-turn shaft is disengaged from the final gear in the home position to permit manual actuation of a thumb-turn.

A method for operating a deposit-operated lock system for a borrowed object, in particular for a transport trolley which can be moved by hand. There is also described a suitable deposit-operated lock system. A key that is held in a deposit lock is released when an electric drive drives a carriage that is displaceably mounted on a blocking element in an initial position.
