NOTE: You must be in NORMAL mode to 
program the AC-020. DOOR 1 / DOOR 2 
LED will be green. 
Wrong or timed out entries will reset the 
controller to the NORMAL mode 
condition. 
To exit programming, press the “*/#” key 
for two seconds. Three beeps are 
generated and the system will return to 
NORMAL mode. A short press on the 
“*/#” key will also return the system to 
NORMAL mode, and a long beep will be 
heard. This aborts the programming, but 
in some cases, such as Program 
Function #7, data may have already 
been programmed. 
Wrong entries during programming may 
also abort programming, along with long 
beep generation. 
All programming operations are done 
either from the on-board keyboard or 
from the reader. Programming the 
PROX. employee codes requires using 
proximity reader and proximity cards.
