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

Deliver scalable I/O expansion for access control and security monitoring with the Alarm.com ADC-AC-X300 HID Aero output control module. Designed specifically to extend the capabilities of an Alarm.com X1100 Door Controller, the X300 adds 12 relay outputs and two programmable inputs so you can connect additional locks, gates, ingress/egress sensors and auxiliary devices without rearchitecting the system. Dedicated tamper, AC-fail and battery-fail inputs improve fault detection and reduce false alarms, giving security teams clearer, faster situational awareness. The module supports up to 16 expansion modules per expansion port and up to 31 expansion modules total, enabling large-scale deployments across campus, retail, and multi-tenant facilities. Integration with the Aero platform and Alarm.com ecosystem simplifies commissioning and centralized monitoring, lowering installation time and lifecycle costs. Ideal for integrators and IT/security managers who need dependable expansion for access control, surveillance and facility monitoring.
