Operating Procedure
To operate the CC-8521A, enter the valid 3-5 digit PIN code on the keypad. When the
valid PIN code is entered, the green LED on the keypad will illuminate and the door
lock will release.
The keypad has a build-in visitor annunciator button. Pressing this button causes an
annunciator to sound in the control unit. If an external audio or visual device is
connected, it will also activate when this button is pressed.
If one or more incorrect PIN code digits are entered, the system will enter a penalty
mode and will not recognize any digits for the programmed 3-60 seconds. After the
penalty time has elapsed, the unit will return to normal operation and entering the valid
PIN code on the keypad will release the door.
If the external release button has been installed, it can be used by an attendant to
release the lock from a location on the secure side of the door.
