Sargent 8271-24V Lnl 26D Electrified Mortise Lock

Product Description

The SARGENT 8271-24V LNL 26D is a fail-secure electrified mortise lock designed for access-controlled door openings in commercial and institutional facilities. Operating on 24 volts DC, this lock remains locked when power is removed, making it the correct choice for security applications where fail-secure function is required by code or design. It is configured with an LN rose trim and an L lever handle in a Satin Chrome (26D) finish. Installation is typically performed by a licensed locksmith, access control technician, or commercial door hardware installer working alongside an electrical or low-voltage contractor.

This electrified mortise lock is suited for interior and exterior door applications in commercial buildings, schools, healthcare facilities, government buildings, and other facilities requiring card reader, REX device, or access control panel integration. The fail-secure configuration means the latch bolt remains locked during a power loss event, which is a common requirement for perimeter doors and secured interior zones. The LN rose and L lever trim provide a clean, low-profile appearance consistent with institutional hardware standards.

Installation Notes

Installation should be performed by a qualified commercial door hardware technician or licensed locksmith in coordination with a low-voltage access control contractor. Power down the access control panel and de-energize all associated wiring before servicing or replacing the lock. Mortise lock installation requires precise pocket routing in the door edge; consult the manufacturer template for door prep dimensions. Wiring must comply with applicable local electrical codes and NFPA 70 (NEC) requirements for low-voltage control wiring.
