    Abstract: An apparatus for securing a door includes a latch bolt which engages the door frame when extended and prevents the door from opening. To release the door the latch bolt is retracted by manually operated operating means, and a dogging mechanism retains the operating means in a position wherein it holds the latch bolt in its retracted position. This enables the door to be opened and closed during periods of high use without operating any of the parts of the apparatus, thus reducing wear and preventing early failure. The dogging mechanism is electrically operated and is controlled from a remote location.

    Abstract: 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.

    Abstract: A door exit device may include a light source for indicating a status of the exit device. The light source may be capable of providing a first indication denoting that the exit device is in a first state (e.g., a dogged state) and a second indication denoting that the exit device is in a second state (e.g., an undogged state). Further, the exit device may include first and second parallel control systems capable of electronically controlling that status of the exit device. In some instances, a first parallel control system may supersede a second parallel control system.

    Abstract: 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.
