Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

A latch is configured to be affixed to an inner portion of a door to an enclosure and to engage a catch attached to an inner portion of the enclosure when the door is in a closed position/ A housing is affixed to an outer portion of the door and includes a memory device and a latch controller configured to detect when the latch is no longer within a proximity of the catch. The controller is configured to electronically open the latch to open the access door. The housing also includes an emergency access portal aligned with and providing access through the access door by an instrument to at least the catch to engage the catch and release the access door. The latch controller detects that the latch is no longer within the predetermined proximity of the catch and registers the opening of the latch in the memory device.

An automatic-alarming push-down type emergency door-locking device, disposed at a door board, includes a main lock seat, a secondary lock seat, a push-down type handle assembly, a position-sensing module and an alarm module. The main and secondary lock seats are disposed at the door board, and the main lock seat has at least one locking element. In the push-down type handle assembly, a first handle and a second handle are connected pivotally with the secondary and main lock seats to be moved along a driving path from a locking position toward an unlocking position. At the locking or unlocking position, the locking element is buckled with or separated from the at least one locking groove. The position-sensing module transmits an alarm-triggering signal for the alarm module to generate an alarm, upon when the first handle leaves the locking position.

A breakaway catch includes an anchor portion configured to secure to an inner surface of the enclosure, and a catch module configured to be removably affixed to the anchor portion. The breakaway portion is detachably coupled to the catch module and configured to interface with a latch member to secure the access door of the enclosure in a locked state, wherein the breakaway portion is configured to detach from the catch module responsive to engagement of an instrument with the breakaway portion and while the latch member is interfaced with the breakaway portion to secure the access door. When the breakaway portion is detached from the catch module, the latch member is released from securing the access door such as to place the access door in an unlocked state and provide access to the enclosure.

A building alarm system and automated door lock arranged to place the alarm system in an armed state when a door lock fails to engage to lock an associated door in a closed position. Activation of a single button by a user or use of specific code by a user to gain access to a building can cause the alarm system to automatically rearm and for door locks at the building to be locked after entry by the user. A first responder code can be used by first responder personnel to gain access to a building after an alarm system indicates an alarm state, e.g., that corresponds to an emergency condition.

An attachment system for a door or window, the attachment system being configured to sense a condition of a door or window, the attachment system including: a securing member configured to be mounted to a frame member of the door or window; and a module, configured to be coupled to a frame member by attachment to the securing member, the module including a sensor to sense the condition of the door or window, and the securing member including a resiliently biased clip configured to retain the module in attachment to the securing member selectively, wherein the securing member is configured space the module from at least part of the frame member such that the sensor is positioned to sense the condition of the door or window.

An emergency-deployable door lock system configured to reinforce a door against unauthorized entry during high-risk events. The system includes a locking mechanism mounted to either the door or the frame and a strike receiver mounted to the other, with a rotatable turning latch configured to engage the strike receiver when activated. The locking mechanism may be engaged manually via a thumb turn or remotely via a wireless signal received from a handheld remote control. A status light is coupled to the locking mechanism and configured to indicate lock state by emitting light patterns or colors. The system may optionally include an interior-facing camera and be powered by either a dedicated battery or a hardwired power source. The device may be optimally retrofitted for installation in schools, offices, and other facilities where rapid lockdown and visual lock-status confirmation are important to occupant safety.
