Abstract
A delayed egress exit push rail system for a door has a push rail movable relative to a housing between a home position and a second position to open the door, a sensor for determining the position of the push rail as the push rail moves between the home position and the second position and a controller connected to the sensor. The sensor detects a current position of the push rail in the home position and the controller determines if the current position of the push rail detected by the sensor is within a predetermined acceptable range of positions relative to the home position. If the controller determines that the current position of the push rail is outside of the predetermined range, the controller unlocks the door for immediate egress, relays an error message via light or sound and/or communicates with a remote monitoring device.
