Replacing a Lost Normal/Secure Code
The AC-Q74 must be in Secure Mode; otherwise, this does
not work. Make sure that the Mode LED is red before
proceeding.
To replace a lost normal/secure code:
1.
Remove power from the Power Supply Unit (PC-25T).
2.
Press the REX Button on the Power Supply Unit (PC-25T).
3.
Apply power to the unit with the REX button pressed.
4.
Release the REX Button.
5.
You now have 15 seconds to program a new Normal/Secure code
into the Access Control unit using the initial default code 3838,
before the controller reverts to the existing code.
