Sargent 70-8271-24V Lnb 26D Electrified Mortise Lock

Product Description

The SARGENT 70-8271-24V LNB 26D is a fail-secure electrified mortise lock designed for commercial door hardware applications requiring electric access control. Operating at 24 volts, it holds its locked state when power is removed - a critical requirement for perimeter doors and secure-area egress points. The lock features an LN-style rose trim, a B-style lever, and is prepared for Small Format Interchangeable Core (SFIC) use without a core included. The finish is Satin Chrome (26D). Licensed locksmiths, security integrators, and commercial door hardware technicians are the primary installers.

This electrified mortise lock is suited for commercial and institutional buildings where electric access control is integrated into perimeter or interior security doors. The fail-secure configuration means the lock remains locked during a power loss, making it appropriate for controlled-access doors where maintaining security during outages is the priority. The SFIC prep allows the end user or facility manager to install a compatible small format interchangeable core cylinder once the door is in service. The LN rose and B lever configuration meets common commercial trim standards for office and institutional environments.

Key Features

• Fail-secure operation - lock remains locked when power is removed
• 24-volt electrified mortise lock body for integration with access control systems
• LN-style rose trim with B-style lever for standard commercial door applications
• SFIC prep less core - accepts Small Format Interchangeable Core cylinders (core sold separately)
• Satin Chrome (26D) finish for corrosion resistance and clean commercial appearance

Compatibility

Designed as an OEM-style electrified mortise lock for commercial door assemblies requiring 24-volt fail-secure access control with SFIC cylinder prep.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with electrified mortise lock wiring and access control system integration. Disconnect and lock out all electrical power to the access control panel and door circuit before servicing or wiring the lock. Consult local building and fire codes, including applicable NFPA and IBC requirements, for egress and fail-secure hardware compliance on the specific door opening. The SFIC core must be ordered and installed separately before the lock is fully operational as a keyed device.
