The ACC can be programmed with up to 1,000,000 cardholders and will grant access when a cardholder presents a valid access card at a secure door.

The ACC has been specially designed for maximum flexibility, and provides four separate Field Level Network (FLN) channels. Each FLN is capable of hosting up to 16 local devices for the control of access, monitoring input devices or controlling output devices.

The ACC hosts a diagnostic port that allows a direct connection to its microprocessor to facilitate the download of operating instructions (firmware). Firmware updates are made without having to visit the controller cabinets. To facilitate communications with the host system, the ACC provides a 10/100Mb Ethernet connection. This allows communications over any WAN or LAN where devices on the network can be assigned a unique IP address. This type of communication ensures the fastest possible transaction times between the host system and ACC field panels.

To ensure that the ACC always monitors the access and security of an enterprise, it provides a port for the connection of a backup battery. During those times of power failure, the backup battery will permit the ACC to maintain the integrity of the access control and security system.

The ACC hosts a Tamper input that can be used to detect if the cabinet in which it has been mounted has been opened. It also provides an alarm output to visually or audibly sound an alarm when security has been breached.
