Sargent 8270 LNL US26D Electric Mortise Lockset - Fail Safe, Locks Outside Lever

The Sargent 8270 LNL is a high-performance Grade 1 Heavy-Duty Electrified Mortise Lockset engineered for seamless integration into modern access control systems. Built upon the legendary Sargent 8200 Series chassis, this electrified solution provides the ultimate balance of physical strength and electronic versatility. The 8270 Fail Safe Function is specifically designed for life-safety applications, ensuring that the exterior lever unlocks automatically during a power outage or fire alarm activation to allow unhindered entry for emergency responders.

Intelligent Electrified Control (70 Function - Fail Safe)

The 8270 function operates on a "Power-to-Lock" logic, making it the premier choice for stairwell doors and perimeter entries where fire codes mandate re-entry capabilities during an emergency.

• Fail Safe Logic (Power ON, Locks Outside Lever): When power is applied, the outside lever is locked. When power is removed (via a fire alarm or power failure), the outside lever is instantly unlocked.
• Key Override: Regardless of power status, a physical key in the Sargent LA Keyway always retracts the latchbolt from the exterior, providing a reliable mechanical backup.
• Universal Voltage: The high-efficiency solenoid is designed to operate on either 12VDC or 24VDC, offering maximum flexibility for various security power supplies.
• Constant Free Egress: The inside lever always retracts the latchbolt, providing an immediate exit at all times to comply with NFPA 101 Life Safety and ADA codes.
• Auxiliary Deadlatch: Features a stainless steel deadlatch that prevents "shimming" or unauthorized manipulation of the latchbolt.

Architectural LNL Trim & US26D Finish

The LNL trim configuration combines the high-strength LN Escutcheon with the ergonomic L Lever, finished in a brilliant US26D Satin Chrome.

• LN Escutcheon Plate: A heavy-duty wrought metal escutcheon that reinforces the door and provides a clean, professional appearance.
• L Lever Design: A sleek, linear profile that is fully ADA compliant, ensuring easy operation for all users.
• Verified Endurance: Independently verified to withstand 14 million cycles, ensuring an exceptionally low total cost of ownership in high-traffic environments.

Critical Installation Component: The QC8 Hinge

To ensure the long-term reliability of your electrified opening, Sargent recommends the use of a QC8 Hinge with the 8270 LNL lockset.

• Seamless Power Transfer: The McKinney QC8 (ElectroLynx®) Hinge provides the necessary concealed conduit to transfer power from the frame to the electrified lockset without visible wires or moving parts that can be tampered with.
• Plug-and-Play Integration: Utilizing the QC8 8-wire connector allows for a "snap-together" installation, reducing wiring errors and significantly shortening labor time during setup.
• System Longevity: Unlike door cords or loops, the QC8 hinge protects the wires from the constant pinching and fatigue of high-frequency door cycles.
