Description

SDC/Security Door Controls 400U-RMB 4-Door Access Controller

Overview

The SDC 400U-RMB is a networked access control controller designed for multi-door installations. It manages access credentials across four doors, supporting up to 250,000 user records. The integrated buzzer output enables immediate audio feedback on the 1-gang wall plate. Operating at 24VDC, it integrates directly into existing HID credential systems and TCP/IP networks.

Compatibility

Communicates via OSDP and TCP/IP protocols, making it compatible with enterprise access control systems and HID reader ecosystems. Ideal for integrators deploying distributed door control across facilities, retail locations, and multi-tenant environments. Supports credential management at scale without requiring a central server for each installation point.
