Sdc/Security Door Controls Z7852LQRS Networked Deadbolt Strike

Overview

The Z7852LQRS is a networked deadbolt strike designed for enterprise access control deployments. It communicates via OSDP and TCP/IP protocols, supporting multi-credential authentication including DESFire, MIFARE, NFC (13.56MHz), and 125kHz proximity cards. This architecture enables flexible credential migration and mixed-reader environments across your security infrastructure.

System Capacity & Credentials

Manages up to 250,000 user records across 63 doors per controller. Multi-credential support reduces hardware footprint and allows credential type flexibility without system redesign. Operates on 24VDC power.

Compatibility

Purpose-built for integration with access control systems requiring OSDP or TCP/IP communication. Suitable for security integrators deploying networked door control across multi-building facilities, hospitality properties, corporate campuses, and secure facilities requiring credential diversity and centralized management.
