Abstract: An exemplary access control device includes a locking member having a locked position and an unlocked position; an electronic actuator operably connected with the locking member; a switch connected between the electronic actuator and a power supply, the switch having a closed state in which the electronic actuator is connected to the power supply and is operable to maintain the locking member in the unlocked position, the switch having an open state in which the electronic actuator is disconnected from the power supply; and a manual actuator operable to transition the switch between the open state and the closed state.

Abstract: An exit device located in a door frame having a door strike including a latchbolt assembly, a pushbar assembly, and a link assembly. The latchbolt assembly includes an extended position configured to engage the door strike, and a retracted position configured to move past the door strike. The pushbar assembly moves from a released position to a pressed position to move the latchbolt assembly from the extended position to the retracted position. The link assembly is operatively connected to the pushbar assembly and includes a security link having an elongated aperture and a pin configured to extend through the elongated aperture about which the security link rotates. A keeper surrounds the pin and supports the security link for rotation. In the event of extreme heat, the keeper melts and the security link moves to a position to substantially prevent opening of the door.

Abstract: 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.

Abstract: There is disclosed an exit trim that permits simplified changing of the handing of a lever handle between a left hand and a right hand orientation. The handing orientation of the lever handle can be repositioned without disassembling the exit trim or removing components positioned within the exit trim.

Abstract: A motor assembly is provided that includes an audible indicator for an access control device for a door, such as an exit device or an auto-operator. The audible indicator is configured to provide an audible output in response to a signal that initiates operation of the motor to change a state of a latch or open the door.

Abstract: An exemplary exit device system includes a pushbar assembly and a control system. The pushbar assembly includes a latch having an extended position and a retracted position, a blocking member having a blocking position in which the blocking member retains the latch in the extended position and an unblocking position in which the blocking member permits the latch to move to the retracted position, a pushbar operable to move the blocking member between the blocking position and the unblocking position, and an electronic driver operable to move the blocking member between the blocking position and the unblocking position. The control system is configured to operate the electronic driver to electrically move the blocking member between the blocking position and the unblocking position based upon information received from a credential reader.

Abstract: An exit device assembly includes a pushbar assembly configured for mounting to an egress side of the door, a trim configured for mounting to a non-egress side of the door, at least one remote latch mechanism on the egress side of the door, a latch control mechanism mounted to the door for manipulating the at least one remote latch mechanism, a key mechanism on the non-egress side of the door separate from the trim, and a trim lock device on the egress side of the door. The trim lock device is operable to prevent ingress through the door via the trim, while restricted ingress is provided by the key mechanism while the trim is locked from the egress side. The pushbar assembly is operable to always provide egress.

The handing orientation of the lever handle can be repositioned without disassembling the exit trim or removing components positioned within the exit trim.

Abstract: A force adjustment mechanism configured for use with an exit device including a pushbar having an extended position and a retracted position. With the pushbar in the extended position, the pushbar resists movement toward the retracted position with a net resistive force. The force adjustment mechanism is operable to adjust the net resistive force.

Abstract: An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism.

Abstract: An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input shaft 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 elastically deform without moving the link from the second link position.

Abstract: An exemplary pushbar assembly generally includes a mounting assembly, a latch control assembly movably mounted to the mounting assembly, a pushbar operable to actuate the latch control assembly, a master cam rotatably mounted to the mounting assembly, a slide plate, and an insert.
