An indicator assembly according to certain embodiments generally includes a mounting bracket, a follower, a transmission ring, and an indicator plate. The follower is rotatably mounted to the mounting bracket, and is configured to receive a tailpiece of an input device. The transmission ring is rotatably mounted to the mounting bracket, and is engaged with the follower. The indicator plate is slidably mounted to the mounting bracket for movement between a first indicator plate position and a second indicator plate position to selectively place a first indicium of the indicator plate within a reference area. The transmission ring is operably connected with the indicator plate such that movement of the transmission ring between a first transmission ring position and a second transmission ring position drives the indicator plate between the first indicator plate position and the second indicator plate position.

A bar handle with incorporated lock having a tubular element for gripping a handle, installed on a face of a door by way of interposition of at least one spacer element, and a lock which is at least partially contained inside the tubular element. The handle includes a release device for releasing the lock, which is configured to be operated manually with a pusher element installed on the tubular element. the handle comprises a release device for releasing the lock, which is configured to be operated manually with a pusher element installed on the tubular element.

An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input is connected to an actuator that linearly displaces the input shaft, and the output shaft is connected to a locking member of the exit device. The over-travel mechanism includes a link coupled to the output shaft, and a preloaded elastic member transmits force between the input shaft and the link. Movement of the input shaft from a first input shaft position to a second input shaft position causes the elastic member to urge the link from a first link position toward a second link position. Movement of the input shaft from the second input shaft position to a third input shaft position causes the elastic member to elastic member to elastically deform without moving the link from the second link position.

A system may be configured to detect an emergency condition at a premises; dispatch one or more autonomous drones to a location associated with the emergency condition; receive from the one or more autonomous drones, sensor data associated with the emergency condition; generate, based on the sensor data, a plan identifying an evacuation route for safely evacuating the premises; and transmit an instruction that causes the one or more autonomous drones to indicate, to one or more persons in a vicinity of the emergency condition, the evacuation route. The system may further detect, based on the sensor data, one or more safe areas in the premises, and the evacuation route may pass through at least one of the one or more safe areas.

An emergency exit system comprising a first primary structure frame, a second primary structure frame extending substantially parallel to the first primary structure frame, a door opening arranged between the first primary structure frame and the second primary structure frame, and a door shiftable substantially parallel to the first primary structure frame and the second primary structure frame between a closed position and an open position. In the closed position, the door closes the door opening. In the open position, the door opens up the door opening. At least one of the primary structure frames comprises a primary structure guide element for guiding the door when the door is shifted between the closed position and the open position.

A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.

Embodiments described herein relate to an exit device having a construction that facilitates visual inspection of the state of the exit device. Embodiments of the exit device include a visual indicator as to the state (dogged or undogged) of the exit device.

An exemplary closure assembly includes a swinging barrier, a pushbar assembly mounted to a first side of the barrier, a remote trim assembly mounted to a second side of the barrier, and a transmission assembly that extends at least partially through the barrier and couples remote trim assembly and the pushbar assembly. The pushbar assembly includes a latchbolt and a pushbar operable to retract the latchbolt. The remote trim includes a handle that is operably coupled with the latchbolt via the transmission assembly such that the handle is operable to retract the latchbolt. The handle is positioned above the pushbar such that a vertical offset distance is defined therebetween. The offset distance is selected such that a user having a height within a selected range of heights is able to actuate the pushbar assembly, but cannot actuate the trim assembly.

An exit device assembly for coupling to a door having a first side and second side. A first exit device may be coupled to the first side of the door. The first exit device may include a main tube extending from a first end to a second end and a first adjustment tube coupled to the first end of the main tube. The first adjustment tube may be axially adjustable relative to the main tube along a first adjustment axis. An actuator assembly may be supported within an interior of the main tube of the first exit device and may be moveable between a first position and a second position. A latchbolt may be coupled to the actuator assembly and may be moveable between a retracted position and an extended position in which the latchbolt engages a latch.

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.
