Alarm.com ADC-AC-X300 Hid Aero Output Control Module

Product Description

The ALARM.COM ADC-AC-X300 is an output control expansion module designed for access control systems. It adds 12 additional outputs and 2 additional inputs to an existing installation, expanding the switching and monitoring capacity of a supported door controller. The ADC-AC-X300 is part of the Aero product line and is installed by licensed security and low-voltage technicians working on commercial access control deployments. It integrates directly with the Alarm.com ecosystem, allowing centralized management of expanded I/O points through the platform.

The ADC-AC-X300 is intended for commercial access control installations where additional relay outputs or monitored inputs are needed beyond what the primary door controller provides. It is used in scenarios such as controlling auxiliary door hardware, locking devices, or external notification equipment. The module pairs with the Alarm.com X1100 Door Controller, extending its I/O capability without requiring an additional primary controller.
