Sdc/Security Door Controls LR100DMK Electric Latch Retraction Controller

Overview

The LR100DMK is a multi-door access control controller designed for enterprise and mid-scale security deployments. It manages up to 63 doors from a single controller unit, supporting 250,000 user credentials. The system accommodates multiple credential types—DESFire, MIFARE, NFC (13.56 MHz), and 125 kHz proximity—making it compatible with mixed-credential environments common in large installations.

Compatibility

Communicates via OSDP and TCP/IP protocols, enabling integration with standard access control management systems and networked security infrastructure. The electric latch retraction mechanism suits controlled entry applications requiring reliable, repeatable door release. Ideal for integrators standardizing on multi-protocol, multi-credential platforms.
