SDC LRSG2R LR100 Sargent Rex Access Control Kit

Overview

The SDC LRSG2R is a network-based access control kit pairing the LR100 reader module with Sargent Rex integration for multi-door facility deployments. It handles up to 63 doors and 250,000 user accounts, making it suitable for mid-to-large commercial, institutional, and industrial installations where centralized credential management over IP is required — no local server dependencies needed.

Compatibility

The LRSG2R integrates with Sargent Rex-based door hardware and access control ecosystems. It communicates via OSDP (Open Supervised Device Protocol) and TCP/IP, enabling integration with enterprise access control management platforms. The LR100 reader supports DESFire, MIFARE, NFC at 13.56MHz, and 125kHz Proximity credentials — multi-technology credential support allows mixed card/badge formats within a single deployment without requiring separate reader hardware or parallel access control branches.

Installation Notes

Deploy this kit in networked environments where centralized control and credential provisioning are priorities. OSDP and TCP/IP connectivity requirements mean adequate network infrastructure (managed switches, UPS-backed PoE or hardened power) should be in place before installation. Confirm Sargent Rex door strike and controller compatibility with your existing hardware before committing to the LR100 reader module.
