Sdc/Security Door Controls 400U-L2 Wall Mount Annunciator

Overview

The SDC 400U-L2 is a wall-mounted annunciator designed for multi-door access control installations. It supports up to 4 doors with HID credential authentication and integrates into enterprise access control systems via OSDP and TCP/IP protocols. Operating at 24VDC, this device manages credential verification for up to 250,000 users, making it suitable for mid to large-scale facility deployments where centralized door status monitoring and control are required.

Compatibility

The 400U-L2 integrates with HID-based access systems and communicates through industry-standard OSDP and TCP/IP interfaces. It is compatible with security integrator installations supporting 4-door configurations and enterprise credential management systems requiring high user capacity. Ideal for facilities requiring distributed annunciator placement with centralized command visibility.
