A key for an electromechanical locking device includes a key bow, and with the key bow includes a housing and an, in particular single, button. The housing includes an actuating section for actuating the button and a support section for supporting the actuating section, with the actuating section and the support section being configured in one piece with one another.

A method of saving energy for a locking system, in which, upon completion of a working cycle, an energy-saving circuit in an electronic control board of an electronic key picks up, in response to a signal from a microcontroller, a signal from a second OR input, said signal transferring a power source into an energy-saving mode in which the supply of power to a control circuit is completely shut off. When the power source of the key needs to be activated, the circuit board of an electronic lock draws power from the battery of the key and sends a signal to the electronic key, wherein the circuit for extracting an activation feature from an external event does not use energy from the battery.

A modularized electric latch control device includes a mounting seat and a locking cap device pivotably mounted to the mounting seat and pivotable relative to the mounting seat between a closure position and a non-closure position. Optionally mounted to the electric latch control device are a stopper, a closure member, a locking latch restraining frame, a first escutcheon, and a second escutcheon. The electric latch control device is selectively assembled into a first mode (including the first escutcheon), a second mode (including the closure member, the stopper, and the second escutcheon), or a third mode (including the locking latch restraining frame, the stopper, and the second escutcheon) for cooperating with a cylindrical latch device, a first box type latch device, or a second box type latch device.

This disclosure provides systems and methods for lockout-tagout procedures and systems supporting the same, including, without limitation, locking devices that can store and be locked simultaneously by multiple keyholders. In various embodiments, a single user can add multiple keyholders to a locking device. The user may not be able to remove anyone as a keyholder except himself or herself. Thus, the locking device may remain in a locked state until each of the added keyholders applies their digital key, password, PIN, and/or other personal identifying information to unlock the locking device by removing themselves as a keyholder.

An electronic lockset mounted on a door, the electronic lock including a lock to prevent the door from opening when in a locked state, a handle to open the door when the lock is in an unlocked state, a sensor to sense whether a non-electronic key has attempted to open the lock, and a printed circuit board to store information sensed by the sensor.

A wireless, electronic interchangeable locking core insertable into a core receptacle, the locking core including an outer housing and a lock core that is selectively rotatable via an external handle between a locked position and an unlocked position. The handle is prevented from rotating the locking core unless wirelessly-provided authorization credentials are validated and/or a pattern of physical input interactions with an electronic sensor is matched with a stored pattern. The pattern may be defined, for example, as a sequence of short and long interactions with a button, light sensor, touch panel, or the like. The electronic interchangeable locking core may include a battery and be configured for installation in small format interchangeable core (SFIC) housings.

A lock operating device (100) configured to be retrofitted on an electromechanical lock (200) having a key-receiving portion (210) is provided. The lock operating device (100) comprises a maneuver knob (110) and a key blade (120) being operably connected to the maneuver knob (110) and being insertable in said key-receiving portion (210) of the electromechanical lock (200), and circuitry (130) which includes wireless communication means (132) arranged to wirelessly receive authentication information, and which circuitry (130) is arranged to communicate the received authentication information to the electromechanical lock (200) via the inserted key blade (120). The lock operating device (100) thereby allows conversion of the electromechanical lock (200) from a first operating mode, in which the electromechanical lock (200) can be operated by a programmable physical key receivable in said key-receiving portion (210), to a second operating mode in which the electromechanical lock (200) is arranged to receive said authentication information wirelessly and be operated by the maneuver knob (110).

A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.

A system to detect an unauthorized attempt to open a security lock (1-6), the system comprising a camera (10), which is directed towards the vicinity of the security lock; a communications connection between a camera (10) and a predefined mobile station (13); and a detector or sensor (8, 9), which is arranged to start the camera for transmitting a picture via said communications connection to the mobile station. The system further comprises a safety device (6) of the lock, having a safety latch (16), which has a locking position and an opening and, in which locking position, the mechanical opening of the lock with a key and/or rotary knob is prevented; at least one detector or sensor (8, 9), which is located in connection with the lock or door and arranged to detect at least one of the following events: (i) the presence of a key in the key channel (4) of lock, (ii) a movement or vibration of the door, (iii) a movement or vibration of a part of the lock. The control unit (7) of the safety device (6) is arranged to start the camera (10), when the detector or sensor (8, 9) detects one of above said events. The control unit (7) is arranged to start the camera (10) automatically only if the safety latch (16) of the safety device (6) is in the locking position and the detector or sensor (8, 9) detects one of above said events.

A mortise lock assembly is disclosed that enables a position of a door associated with the mortise lock assembly to be determined despite whether a deadbolt is in a retracted state or an engaged state. An auxiliary latch assembly transitions between an engaged state and a retracted state. A main latch assembly may also transition between an engaged state and a retracted state. A magnetic field sensing device that is positioned on the auxiliary latch assembly detects a magnetic field generated by a magnetic field generating device positioned on a door strike. The magnetic field sensing device is positioned on the auxiliary latch assembly such that the magnetic field sensing device is aligned with the magnetic field generating device positioned on the door strike when the door is in a closed position. The magnetic field sensing device may also be positioned on the main latch assembly in a similar manner.
