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.

One embodiment relates to an exit device assembly. The exit device assembly includes a center case, a push pad movably mounted on the center case, and a mechanical case coupled to the center case, wherein the exit device includes an opening. The assembly also includes a sensor aligned with the opening, wherein the sensor is structured to detect a user from a distance through the opening and to generate an output signal in response to detecting the user. The assembly also includes a latch and a latch actuator. The assembly also includes a controller in communication with the sensor and the latch actuator, wherein the controller is structured to transmit an actuating signal in response to receiving the output signal from the sensor, wherein the latch actuator is configured to move the latch from the locked position to the unlocked position in response to the actuating signal.

An exit device assembly for use in association with a door having a top, a bottom and a generally vertical surface. The exit door assembly includes an exit device configured to be mounted on the surface of the door, the exit device including a manually movable member, a latch mechanism configured to be mounted adjacent one of the top and the bottom of the door, the latch mechanism including a latch movable between a locking position and a non-locking position, and a non-rigid device for causing movement of the latch in response to movement of the manually movable member.

An exemplary damper module is configured for use with a latchbolt assembly, and generally includes a mounting bracket, a first slowing mechanism, and a second slowing mechanism. The latchbolt assembly generally includes a drive member, a latchbolt, and a retractor connected between the drive member and the latchbolt. Each of the slowing mechanisms is independently operable to slow the extension speed of the latchbolt. The first slowing mechanism includes a rack gear and a rotary damper including a pinion gear. The rack gear is configured to be mounted to the drive member, and the rotary damper is mounted to the mounting bracket. The second slowing mechanism includes a slowing arm and a biasing member engaged with the slowing arm. The slowing arm is movably mounted to the mounting bracket and is configured to engage the retractor.

A vertical rod coupler includes a bracket, bolt, and cam lock. The bolt is disposed through the bracket and the cam lock, and includes a head and a transverse pin. When the bolt is rotated relative to the cam lock, a pin camming surface cams the transverse pin to adjust the tension in the bolt and/or a distance between the head and the bracket.

An improved roller latch bolt that asymmetrically locates the roller within a roller support is presented. The improved design allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate. The improved roller latch bolt maintains the smooth operation of roller latch bolts while also providing the increased door security and other benefits of non-roller latch bolts.

An exemplary access control device is configured for mounting to a door and includes a bolt, an actuator, and an indicator. The bolt has an extended position and a retracted position, and includes a front face that is visible when the bolt is extended and the door is in a closed position. The actuator is operable to move the bolt from the extended position to the retracted position. The indicator is positioned on the front face of the bolt such that at least a portion of the indicator is visible when the bolt is extended and the door is in the closed position.

A door latch system includes an exit device having a housing mounted to an unsecured side of a door. A latch assembly is mounted in the housing and includes a latch for releasably securing the door in a door frame. An actuating assembly includes a driving member. A push bar is configured to be received within the housing. Relative movement between the push bar and base plate so as to reduce the distance between the push bar and base plate moves the driving member and latch to release the door from the door frame. A dashpot is connected to the driving member and configured to allow movement of the driving member when the push bar is manually depressed but to resist movement of the driving member when a secure side of the door experiences a high velocity impact. A method of resisting unwanted unlatching of the latch is also disclosed.

A low-voltage, direct current apparatus for controlling a door. The apparatus may comprise a mounting bar configured to be coupled to the door and a latch coupled to the mounting bar. The latch may comprise a locking lever, and an actuator may be configured to move the locking lever between a locked position in which the locking lever prevents movement of the latch to an unlocked position in which the locking lever allows movement of the latch.
