Sargent 8273-24V Lnl 26D Electrified Mortise Lock

Product Description

The SARGENT 8273-24V LNL 26D is a double cylinder, fail secure electrified mortise lock designed for controlled-access doors in commercial and institutional applications. Operating at 24 volts, this mortise lock holds the latch or bolt in the locked position when power is removed, making it the correct choice where positive security on power loss is required. It features an LN rose trim and an L lever handle in a satin chrome (26D) finish. Installation and service are handled by licensed locksmiths or commercial door hardware specialists familiar with electrified mortise hardware.

This lock is suited for interior and exterior single or double door openings in commercial buildings, schools, healthcare facilities, and government installations where access control integration is required. The 24-volt input allows direct connection to standard access control panels and electric power transfer hinges or door loops. The double cylinder configuration requires a key on both sides, which is appropriate for doors where free egress must be controlled or where the door is not a required means of egress under local code. Verify applicable building and life safety codes before specifying double cylinder hardware.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with electrified mortise lock systems. Disconnect and lock out all power to the access control system before wiring or replacing the lock.

Double cylinder hardware may be restricted by local fire and building codes on certain egress paths - confirm compliance with applicable IBC and NFPA 101 requirements before installation.
