Sargent 8271-24V Lnj 26D Electrified Mortise Lock

Product Description

The SARGENT 8271-24V LNJ 26D is a fail-secure electrified mortise lock designed for access-controlled door openings in commercial and institutional settings. Operating at 24 volts, this lock remains locked when power is interrupted, making it the correct choice for security-critical applications where unauthorized access during a power failure is unacceptable. The LN rose trim and J lever configuration provide a clean, low-profile appearance. The 26D satin chrome finish resists corrosion and wear in high-traffic environments. Installation is handled by licensed locksmiths, security integrators, or commercial door hardware technicians working to applicable building and fire code requirements.

This electrified mortise lock is suited for commercial interior and entry doors where card readers, keypads, or access control panels provide the triggering signal. Typical installations include office buildings, healthcare facilities, educational campuses, and government buildings where controlled access points require reliable fail-secure operation. The mortise-style body integrates into a standard mortise pocket, accepting low-voltage control wiring routed through the door frame or continuous hinge. The J lever and LN rose are factory-matched to the 26D satin chrome finish for a consistent hardware appearance across the opening.

Installation Notes

Installation should be performed by a qualified locksmith or commercial door hardware technician familiar with electrified hardware and applicable building codes. Power down the access control panel and verify zero voltage at the door circuit before making any low-voltage connections. The mortise pocket must be properly sized for the lock body, and all wiring routed through the door or frame must comply with local electrical and fire codes. Confirm fail-secure vs. fail-safe requirements with the authority having jurisdiction before finalizing installation.
