Andover Controls
Using the AC-1
AC-1 is a complete card access control module designed to interface with the Andover
Controls NetController where an internal firmware-based Access Control supervisor
resides. During normal operation, access control decisions are made in the Continuum
NetController CPU module database, which provides storage for up to 75,000 “local”
personnel records (up to 4 million records may be created per database).
If network communications are interrupted, as a fail-safe mode, the AC-1 will revert to a
programmable degraded mode of operation, providing uninterrupted card access using
site codes, cards formats, and other degrade mode parameters stored in non-volatile
EEPROM in each AC-1 module.
The AC-1 is designed to control a single door. The door can be configured to allow
entrance based on card only, card plus personal ID number (PIN), or keypad only. The
door’s operating mode can even be changed based on time-of-day or other events for
optimum flexibility through Andover Controls’ easy-to-use

language. Each keypad can also permit entry of a duress alarm code that can initiate an
alarm sequence at any AC-1 controller or at the Continuum workstation.
Time-based anti-passback and entry/egress anti-passback are available to prevent
tailgating. Entry/egress anti-passback is system-wide and can be performed by readers
located on different AC-1 controllers across the network.

such as two-man rule, optical turnstile control, and man trap configurations.
Reader Power Switch
Readers are available in both 5 volt and 12 volt varieties. The AC-1 and AC-1-ABA
modules support both by allowing the selection of a reader power source. A voltage
selector switch is located on the front panel of the module. Insert the tip of a small
screwdriver to slide the internal power switch into the desired position.
