The Adams Rite 8600 is a concealed vertical rod (CVR) exit device. Understanding the unlatch process is important for troubleshooting if the device is not working properly.
To start, the crank armature should be at a 90 degree angle. Once the user depresses the push bar, the arm will rotate a set direction depending on the handing of the door. At the same time, the square bolt located at the top rod will retract into the top actuator assembly. The lowering of the square bolt allows the stop plate to rotate over where the square bolt was located. The stop plate and claw rotate in unison, so by unblocking the stop plate, the claw is free to release the strike post located in the header of the door.
After opening the door and letting go of the push bar, the unit will not snap back into a locked state until the door is shut. This is because the claw will come in contact with the strike post. The stop plate will swing out allowing the square bolt to pop back up, blocking the stop plate once more. The square bolt returns to its locked state thanks to the "scissor" inside the push bar, as well as the force of gravity pulling down the threshold bolt (which is geared with the top rod).
