SDC 1511TNHKXE 1511T Delayed Egress Lock

Overview

The SDC 1511TNHKXE is a 1511T delayed egress lock designed for multi-door security installations. It supports up to 63 doors and 250,000 users, making it suitable for enterprise and mid-scale deployments. The lock operates on 24VDC and integrates with modern access control systems via OSDP and TCP/IP communication protocols.

Credential Support

The unit reads multiple credential types including DESFire, MIFARE, NFC at 13.56MHz, and 125kHz proximity cards. This multi-format capability simplifies migration and hybrid installations across different reader ecosystems.

Compatibility

OSDP and TCP/IP connectivity ensure integration with standard access control platforms. The 63-door capacity and 250,000-user maximum support scalable deployments from small buildings to larger multi-facility operations. Delayed egress functionality is critical for high-security or life-safety applications requiring controlled exit timing.
