Description
Schlage ND80LDEL RHO 626 RX Electrified, Fail Safe Lever Lock
Model ND80LDEL RHO 626 RX pairs Schlage's Grade 1 ND Series chassis with the electrified, fail safe function, the Rhodes (RHO) lever and a Satin Chrome (626/US26D) finish. It runs on 12-24VAC/DC and is fail safe. The RX option adds a request-to-exit switch that signals your access control system when someone exits from the inside.
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.
Keying
Ships without a cylinder so you can install one keyed to your existing system.
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
Does it come with a cylinder or core?
Ships without a cylinder so you can install one keyed to your existing system. We can supply a matching core or cylinder; call (877) 202-8118.
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.
