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.

An inner operating device for a door lock is mounted to an inner side of a door and includes a first detecting member electrically connected to an electric driving device. A second detecting member is mounted in a latch device of the door lock. When the first detecting member detects an external force applied to the inner operating device, the electric driving device is activated, and the latch is moved to the unlatching position. When the latch device is set to be in a locked state or an unlocked state, the second detecting device outputs a signal to a lighting device to emit light for indicating the locked or unlocked state. In another example, the lighting device emits light of a first color when the latch device is in the locked state and emits light of a second color when the latch device is in the unlocked state.

An exemplary exit device includes a pushbar assembly, a remote latching assembly, and a coordination mechanism. The pushbar assembly includes a latch control assembly, and the coordination mechanism biases the latch control assembly toward its actuated state. The remote latching assembly includes first and second latch mechanisms, and the latch control assembly is operable to actuate the latch mechanisms. Each of the latch mechanisms at least selectively urges the latch control assembly toward its deactuated state such that the remote latching assembly exerts a variable deactuating force on the latch control assembly. The coordination mechanism selectively retains the latch control assembly in its actuated state, thereby selectively retaining at least one of the latch mechanisms in a corresponding actuated state. When the deactuating force exceeds a threshold force value, the latch control assembly and the latch mechanisms return to the deactuated states thereof.

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.

An inner operating device for a door lock is mounted to an inner side of a door and includes a first detecting member electrically connected to an electric driving device. A second detecting member is mounted in a latch device of the door lock. When the first detecting member detects an external force applied to the inner operating device, the electric driving device is activated, and the latch is moved to the unlatching position. When the latch device is set to be in a locked state or an unlocked state, the second detecting device outputs a signal to a lighting device to emit light for indicating the locked or unlocked state. In another example, the lighting device emits light of a first color when the latch device is in the locked state and emits light of a second color when the latch device is in the unlocked state.

An exit device having a dogging mechanism assembly for providing a visual indication of the state or position of at least certain components of the exit device, such as, for example, a latch, drive rod, and/or a hook bracket. The dogging mechanism assembly includes a displaceable arm actuator mechanism that is coupled to the hook bracket, the hook bracket being adapted to lockingly engage the drive rod. The actuator arm mechanism is adapted to displace an indicator mechanism at least from a first indicator position to a second indicator position as the actuator arm mechanism is displaced to at least one of a first position and a second position. The indicator mechanism has one or more indicators that provide a visual indication of a state or position of a component of the exit device when the indicator mechanism is in at least one of a first and second indicator position.

A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. The push pad exit device further including an improved roller latch bolt. The improved roller latch bolt 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.
