Description
Schlage ND80PDEL RHO 612 Electrified, Fail Safe Lever Lock
The Schlage ND80PDEL RHO 612 is a electrified, fail safe lever lock from the Grade 1 ND Series, finished in Satin Bronze (612/US10) with the Rhodes (RHO) lever. It runs on 12-24VAC/DC and is fail safe.
How the Electrified, Fail Safe function works
The outside lever is locked while power is applied and unlocks automatically when power is removed, so the door releases during a power loss or fire alarm. The inside lever is always free and a key overrides outside.
About the ND Series
The Schlage ND Series is the heavy-duty cylindrical lever lock that many architects specify for schools, hospitals, offices and other busy commercial buildings. It is certified to ANSI/BHMA A156.2 Grade 1, the highest cylindrical lock grade, and is UL listed for use on fire-rated doors. Levers are field reversible, so one lock fits left- or right-hand doors, and the lever shapes meet ADA requirements for operation without tight grasping or twisting.
Because the ND fits a standard 161 cylindrical door prep (2-1/8" bore, 2-3/4" backset), it is a common upgrade when replacing worn or lighter-duty locks without re-machining the door.
Electrified ND locks add a solenoid so an access control system, push button or intercom can lock and unlock the outside lever remotely, while the inside lever always allows free exit. They install in the same cylindrical door prep as a mechanical ND and need a power transfer hinge or door loop to bring wires through the door.

Questions and answers
Will it fit my existing door?
It fits a standard cylindrical prep: 2-1/8" bore with a 2-3/4" backset on doors 1-5/8" to 2-1/8" thick. Other backsets and thin-door kits are available; ask us if your door is different.
Is it fire rated?
The ND Series is UL listed for fire-rated doors when installed with a compatible latch and strike.
Fail safe or fail secure: which do I need?
Fail safe unlocks when power is lost and is often required on stairwell and egress doors; fail secure stays locked and is used where security matters more, like storage and IT rooms. Your local fire code and access control installer have the final say.
