An hand adjustable trim actuator for use with an exit device is provided. The trim actuator uses an actuator shaft with attached actuator gear to engage one of two sets of gear teeth on a linearly moveable retractor. Actuation of the door lever rotates a spindle which has two tabs, one of which pushes the retractor. The engagement of the retractor gear teeth with the actuator gear causes the actuator gear and actuator shaft to rotate which in turn operates the exit device. The actuator shaft and actuator gear are moveably linearly which permits the actuator gear to be disengaged from the retractor gear teeth. Once disengaged, the actuator gear can be rotated and moved into engagement with the other of the two sets of gear teeth, thereby changing the handing of the trim actuator.

Trim actuator for use with an exit device

An electric dogging mechanism for an exit device consisting of slidable plate and armature which are attracted to an electric coil when the coil is energized. The slidable plate is connected to a touch bar mechanism. After the touch bar is depressed, retracting the exit device latch, the coil is energized attracting and holding the armature to the coil, thereby holding the touch bar depressed and the latch retracted by the connection of the slidable plate to the touch bar mechanism.

Electric dogging mechanism for use with an exit device

A combination lock/deadbolt is connected to a push-to-open panic-bar device to operate in response to push-bar operation, thereby withdrawing both the push-bar latchbolt and the deadbolt permitting instantaneous and unrestricted egress from a secured area. To maintain the security of the area from unauthorized entry from outside the secured area, a connection between the push-to-open device and the combination lock/deadbolt assembly is implemented with a lost motion connection. The lost motion device, preferably is a flexible cable transmitting force only in tension, assures that any operation of the combination lock/deadbolt will not effect the security provided by the push-to-open device. Further, the push-to-open device may be provided both with a conventional key cylinder lock and a knob, ever, or thumb lever release on the door exterior. Opening action initiated from outside the door through the knob lever or thumb lever release is mechanically segregated from the cable connection to the combination lock/deadbolt, preventing operation of the push-to-open device from the outside causing operation of the combination lock/deadbolt assembly. Accordingly, an authorized individual must have both a key for the key cylinder lock and the authorized combination for the combination lock in order to gain entry to the secured area, yet anyone may exit the secured area without any restrictions or delay merely by pushing the push-to-open bar.
