Sargent 8271-24V Ll 26D Electrified Mortise Lock

Product Description

The SARGENT 8271-24V LL 26D is a fail-secure electrified mortise lock designed for access-controlled door openings in commercial and institutional applications. Operating at 24 volts DC, the lock remains locked when power is interrupted, making it the correct choice for security-critical openings where a secure state on power loss is required. The unit features an L-style rose trim and L-style lever handle finished in Satin Chrome (26D). Installation is performed by a licensed locksmith or credentialed access control technician working to applicable building and fire codes.

This electrified mortise lock is suited to commercial doors requiring integrated access control, such as office entry points, stairwell doors, and secure interior openings in healthcare, education, and government facilities. The fail-secure operation means the latch bolt remains engaged during a power outage, maintaining the secured condition of the opening until power is restored or mechanical override is used. The L Rose and L Lever trim configuration provides a standard commercial appearance consistent with SARGENT mortise hardware families.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with commercial mortise lock hardware and low-voltage wiring. Disconnect and lock out all power to the access control circuit before handling electrical connections. Verify that the door prep, backset, and strike dimensions match the lock body before installation. Consult applicable local building codes and NFPA 80 for fire-rated door hardware requirements.
