c) A DUAL KEYPAD SPLIT-DECODED ACCESS CONTROL INTER-LOCK SYSTEM
Description
The decoder unit (DA-2800 or DA-2801) provides all the logic circuits for inter-lock connection. An inter-lock system
needs two door controllers. Simply make a pair of cross wire connection on “Output 1 Inhibit” (terminal 9) and “Inter-
lock” (terminal 8) of the two decoders to accomplish the inter-lock functions. This approach is for the important place
requiring high security protection in access control. See page 13-14 Terminals 8 & 9 for more information about
inter-lock.
