Schlage ND12DEU Grade 1 Electrically Unlocked Fail Secure Exit Lock Chassis, Less All Parts, Unfinished

The Schlage ND12DEU is a Grade 1 commercial-grade electrically unlocked exit lock chassis engineered for demanding fail secure access control applications. Designed as a replacement part chassis supplied less all possible parts and unfinished, it provides the mechanical foundation for building or restoring an ND-series exit lock to specification. Its fail secure configuration ensures the lock remains locked upon loss of power, making it appropriate for secured commercial door openings where controlled egress is required.

Key Features

  • Grade 1 Commercial Construction: BHMA/ANSI Grade 1 rated chassis delivers the highest level of durability and performance for heavy-traffic commercial applications.
  • Electrically Unlocked Operation: Fail secure design keeps the lock engaged when power is lost, ensuring controlled access is maintained during power interruptions.
  • Replacement Chassis Configuration: Supplied less all possible parts and unfinished, providing maximum flexibility for integration into existing ND-series lock assemblies or custom configurations.
  • Unfinished for Versatility: Unfinished chassis allows pairing with the appropriate trim and finish components to match existing hardware specifications on the door opening.
  • ND Series Platform Compatibility: Designed for the Schlage ND product platform, supporting a wide range of commercial door hardware configurations and trim options.
  • Commercial-Grade Reliability: Built to Schlage's commercial parts and accessories standards for professional installations where consistent, long-term performance is essential.

Schlage ND12DEU LLL XXX LLL LLL – Frequently Asked Questions

1) What exactly comes in the Schlage ND12DEU order, and what do I still need to buy?
The ND12DEU is the lock chassis only, supplied less all possible parts and unfinished. You get the mechanical core for an ND-series exit lock and nothing else, so the trim, lever or exterior plate, cylinder where the function calls for one, and finish components all have to come from your existing assembly or be ordered separately. It's sold as a replacement part for rebuilding or restoring an ND-series lock, not as a complete lockset for a bare door.
2) Does a fail secure ND12DEU chassis stay locked or unlock when the power goes out?
It stays locked. The ND12DEU is electrically unlocked, meaning power is what releases the outside trim, so when power drops the lock remains secure. That's the right choice for a secured opening where you don't want the door releasing during an outage. If your application needs the opposite behavior, free access on power loss, a fail secure chassis is the wrong part and you want a fail safe version instead.
3) Will a Schlage ND12DEU chassis drop into my existing ND-series lock?
It's built for the Schlage ND platform and is intended for integration into existing ND-series lock assemblies or custom configurations, so the trim and components off an ND lock are what it's designed to work with. Note the function though: ND12DEU is the electrically unlocked exit lock function. Swapping it into a housing that was built around a different ND function changes how the opening behaves, so match the function code as well as the series.
4) I need a complete electrified lockset for a new door, is this chassis the right buy?
No. For a new opening with no existing hardware, a bare chassis leaves you short of everything you need to hang a working lock, since it comes with no trim, no levers and no finish. Buy a complete ND-series electrified lockset instead. The ND12DEU makes sense when you already have an ND lock on the door and the chassis itself has failed, or when you're building a configuration around parts you already hold.
5) Is the ND12DEU rated for high-traffic commercial doors?
Yes. The chassis is ANSI/BHMA Grade 1 and specified for commercial use, which is the heaviest-duty grade in the standard and what most institutional specs call for on corridor, stairwell and entry openings. It shows up in office buildings, schools, healthcare, government facilities, warehouses, retail and multi-tenant residential.
6) What does the ND12 function actually do on the door?
ND12 is an exit lock function: the inside lever always retracts the latch for free egress, and the outside is controlled. In the DEU version that outside control is electrified and unlocked by power. So people can always get out, and getting in depends on the access control system energizing the chassis. That free-egress behavior is what makes it usable on secured openings where code still requires people to leave without a key or special knowledge.
7) Do I order the full model string ND12DEU LLL XXX LLL LLL, or just ND12DEU?
The full designation is ND12DEU LLL XXX LLL LLL. The trailing placeholders are how Schlage indicates the trim, finish and related selections are omitted, which is consistent with this being supplied less all possible parts and unfinished. Quote and order against the complete string so your distributor sends the bare chassis rather than a configured lockset.
8) Why is the ND12DEU chassis unfinished, and does that mean I have to finish it?
The chassis body is the hidden mechanical core inside the door, so it ships unfinished on purpose. Finish lives on the trim: the roses, escutcheons and levers you pair with it. That lets a property manager match whatever finish is already running on the other ND openings in the building without being locked into what the chassis happened to ship with. You don't paint or plate the chassis itself.
