SDC ACM-1 Access Control Module

Optimize door control reliability and simplify system installs with the Security Door Controls SDC ACM-1 access control module. Designed for professional access control and security integrators, this compact control panel module consolidates up to six trigger inputs and provides isolated SPDT relay outputs to interface seamlessly with electrified locks, request-to-exit devices, and alarm systems. Field-selectable dual-voltage support makes it easy to adapt the ACM-1 to existing low-voltage power supplies, while the isolated relay architecture supports small-gauge 22 AWG cable runs up to 1,000 feet—ideal for long-distance connections in campus, retail, or multi-tenant environments.

Built-in LED status indicators speed troubleshooting and monitoring during commissioning and ongoing maintenance, reducing downtime and service calls. Whether you’re upgrading an access control panel or expanding door monitoring and surveillance capabilities, the SDC ACM-1 delivers dependable relay interfacing and clear diagnostics. Add the ACM-1 to your next access control or security project for a faster, more reliable installation—contact your distributor or place an order today.
