SDC 101-4AM Four Door Annunciator Controller

Overview

The SDC 101-4AM is a four-door annunciator controller designed for access control installations requiring centralized multi-door management. This controller supports up to 250,000 users and integrates HID credential readers, making it suitable for enterprise and mid-scale security deployments where door coordination and event monitoring are critical.

Connectivity and Protocol Support

The 101-4AM communicates via OSDP and TCP/IP, enabling reliable integration with modern access control platforms and networked security infrastructure. This dual-protocol support ensures compatibility with both legacy and current-generation systems.

Capacity and Credentials

Built to handle four doors simultaneously with HID credential authentication, the controller supports up to 250,000 user profiles, delivering scalability for growing installations without hardware replacement.

Compatibility

Integrators should verify reader compatibility with HID standards and confirm network infrastructure supports TCP/IP connectivity. The OSDP protocol ensures vendor-neutral integration with compliant access control panels and management software.
