Product Description
Server rooms, pharmacies, evidence rooms, armories — anywhere the door absolutely MUST stay locked even when the power goes out. That's Fail Secure.
The Sargent 8271-24V-LNA-10B-LH is a Fail Secure function mortise lock from the 8200 Series — Sargent's flagship commercial mortise platform that's been trusted on schools, hospitals, office buildings, and government facilities for decades. Fail Secure electric operation wired for 24VDC from your access control panel. The lock stays locked when power is cut — the right choice for secured rooms where losing power should not mean losing security. Inside lever always free for egress.
This one comes with LN Rose, A Lever in Oil Rubbed Bronze — the 10B finish with a living patina that develops character over time. Popular in boutique hotels, upscale restaurants, and residential-feeling commercial spaces.
