Abstract: A locking device comprises a key that comprises a key power coil and a key data coil and an electronically-actuatable lock comprising a lock power coil and a lock data coil. The key power coil and the lock power coil are coaxial and at least partially overlapping one another when the key engages the lock. The key data coil lies in a first plane and the lock data coil lies in a second plane. The first plane and the second plane are substantially parallel to one another.

Abstract: A lockable pipe cover includes an inner cap and an outer cover which are selectively coupled together for axial rotation. When the cap is locked, the inner cap and the outer cover are free to rotate independently from one another thus rotation of the outer cover will not remove the cap from the pipe. In the unlocked position, the inner cap and the outer cover are coupled for rotation and thus rotation of the outer cover results in rotation of the inner cap.

Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.

Abstract: An electronic lock may include a locking mechanism and a cartridge having a body portion and one or more extension receiving portions that may receive the locking mechanism. The lock may also include a first coil positioned around the cartridge, a core disposed within the cartridge and substantially within the first coil, and a second coil positioned around the cartridge. The second coil may be spaced from the first coil. In addition, a first sliding barrier may be disposed within the cartridge, which barrier may be selectively in communication with the locking mechanism. A control circuit may be included in the lock, which may energize the first and second coils to cause the first sliding barrier to move from a first position magnetically attracted to the core to a second position magnetically attracted to the second coil and thereby allow actuation of the locking mechanism.

Abstract: A swivel protection device comprises an enclosure and a locking plug. The enclosure covers a portion of a swivel of a fire department connection that includes a set plug. The set plug holds the swivel onto the fire department connection. The enclosure covers the set plug such that, when the enclosure is locked over the swivel, access to the set plug is severely limited or excluded.

Abstract: A locking cap is selectively locked into place within a tubular opening, such as the open end of a standpipe used to charge a building sprinkler system. The locking cap has an expandable sleeve and a spreader member. As a key is turned, the spreader member is drawn into the expandable sleeve which is urged outward. The outward movement of the expandable sleeve increases a frictional component such that the expandable sleeve becomes frictionally locked within the tubular opening. The key has an end design that is complemented by an end of an actuator shaft such that the likelihood of unauthorized removal of the locking cap is reduced.

Abstract: A locking cover plate can be selectively locked in position on a stortz pipe end fitting or can be unlocked and removed for access to the open pipe end. The cover plate includes a sliding plate that is driven laterally outward into a deployed state by rotating a drive bolt. The drive bolt is coupled to the sliding plate through a torque limiting coupling that transfers the rotation of the drive bolt to translating movement of the latch bar with a cam plate. Movement of the sliding plate is indicated through a front of the cover plate such that the user can identify whether the cover plate is locked on a fitting or simply placed on the fitting without the lock engaged.
