Last modified: Tuesday April 28, 2026.

You can connect sensors and input devices to an Avigilon 32-Input Expansion Board and use them as triggers in Alta Protect zones.

Setup

Connect your trigger devices to the 32-Input Expansion Board, connect the expansion board to an Avigilon Access Control Core (ACC), and then add the devices as sensors in Alta Protect.
