Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

A door security device has a rail support including a top surface and a bottom surface. A door support is attached to the rail support, such that the door support extends vertically away from the rail support of the door security device. The door support is oriented at a normal relative to the rail support. The bottom surface of the rail support rests parallel to a surface of a rail of a crash bar when the bottom surface is situated adjacent the surface of the rail. The security device creates a rigid connection to prevent unwanted removal of the door from a closed position.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

Certain exemplary embodiments can provide a system comprising a schoollock-mount coupleable to a doorframe of a door; a schoollock-pin slidably coupleable to the schoollock-mount; a schoollock-arm slidably coupleable to the schoollock-pin; and a schoollock-door-latch. The schoollock-door-latch is coupleable to the door via the one or more apertures.

A door security assembly for blockading a door in a lockdown situation includes a blockade device. An element of the blockade device insertable into a gap defined by a door and a crash bar that is engaged to the door. Each of a pair of fasteners engaged to the blockade device is selectively engageable the crash bar, so that the blockade device is reversibly engaged to the crash bar with the element positioned in the gap. The blockade device prevents actuation of the crash bar so that the door cannot be opened. The fasteners are positioned so that two hands are required to simultaneously disengage the fasteners from the crash bar to enable disengagement of the blockade device from the crash bar.

An alert system configured to monitor a status of one or more supplemental door locks comprises a switch assembly and an alarm. The switch assembly is configured to detect whether one supplemental door lock is unlocked or locked and includes a switch, an indicator, and a communication element. The switch is to be coupled to a locking component of the supplemental door lock. The switch is configured to sense a position of the locking component and generate an electronic signal or data. The indicator is configured to provide a first indication of a status of the supplemental door lock. The communication element is configured to receive the electronic signal or data from the switch and generate a wireless signal that corresponds to the electronic signal or data. The alarm is configured to generate an audible or visible alarm when the switch assembly detects that the supplemental door lock is locked.

Object of the invention is a door locking foldable safety trim which increases the strength of the door, it ensures a more efficient way to increase safety. The invention has an adjustable button for locking the trim into the desired angle ensuring the proper fitment to secure. With the release button to close and retract back to the closed position completely flushed, thus giving it a natural trim appearance around the door.

A security system for a building includes a plurality of lock modules. Each lock module is associated with a particular door and has an unlocked position and a locked position. Each lock module includes a lock bar, an actuator, and a controller. The lock bar has a first position that allows the particular door to open and a second position that extends from a door frame, a wall, or a floor surface adjacent to the particular door to prevent the particular door from opening. The actuator moves the lock bar between the first and second positions. The controller is operably connected to the actuator and transmits a door status signal that uniquely identifies the particular door. A lock module command signal received by the plurality of lock modules directs the plurality of lock modules to reposition to either the unlocked position or the locked position.

The door viewport with cross-door locking bar laterally spans the door frame with a viewport exterior lip on the door and an interior face plate near an interior of the door forming, in one instance, a mid-bar capture channel. Alternatively, the viewport has an interior extension coacting with a complementary interlocking element on the cross-bar's midpoint. Either construct holds the cross-door locking bar substantially at its mid-point. Cross-bar terminal end mounts removably attach the cross-bar to the door frame. One type of mount is an L-bracket. Another type of mount is a controllable transverse extension member forcing a door frame plate against the door frame. A user-controlled extension means forces the cross-door locking bar away from the door frame plate, with either a screw drive system or a grooved rod with spring loaded lever control.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform.

Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.
