The circuit board in a motor driven Chexit delayed egress exit device and DE5300 delayed egress controller manufactured after 8/24/2015 has a button labeled RESET. This is located between the Blocking Device port and the horn on the circuit board.
This button is used at the factory while programming the circuit board.
Once shipped from the factory, pushing this button is not enough to change the programming.
Effectively, that RESET button has no function once it leaves the factory.
