Schlage ND80EU Fail-Secure Electrically Unlocked Storeroom Lock, ND Series Grade 1

The Schlage ND80EU is a Grade 1 cylindrical storeroom lock with integrated electric unlock capability. The outside lever remains continuously locked until released by key or electric current (fail-secure: locks on power loss). The auxiliary latch deadlocks the latchbolt when the door is closed. The inside lever is always free for immediate egress - no key required from the secure side.

Also available with Request to Exit (RX) function. Electrified functions auto-detect 12V or 24V DC operation, eliminating heated levers. For current draw specifications, refer to the Electrified ND Series Data Sheet linked below.

Schlage ND80PDEU RHO 626AM – Frequently Asked Questions

1) On a Schlage ND80EU, does the door stay locked or unlocked when the power drops?

It stays locked. The ND80EU is fail-secure, so on power loss the outside lever remains disengaged and the opening is still secured. The inside lever is always free, so people can still get out whether or not the door is powered. If you need the outside lever to release on power loss (a stair re-entry or a fire alarm interface), fail-secure is the wrong choice and you want a fail-safe electrified lever instead.

2) What voltage and current does the Schlage ND80EU electrified lever need from the power supply?

The ND80EU auto-detects 12V or 24V DC, so you do not order a voltage-specific version. Size the supply for 0.4A inrush and 0.1A holding per lock. That holding figure is what matters when you are running several locks off one supply on an access control panel.

3) Will the Schlage ND80EU fit the door prep already cut for my existing ND Series lock?

Yes. The whole ND platform uses the standard ANSI 161 door prep, shared across the mechanical ND locks, the wired electrified ND80EU, and the NDE wireless versions, so an existing ND opening takes it directly. The one thing a mechanical-to-electrified swap adds is the wire path: you will need a door cord or electric hinge to get power to the lock, plus the frame prep for it.

4) What backset and strike come standard on the Schlage ND80EU, and will it latch into my existing frame?

Standard latch is the 13-247 deadlatch on a 2-3/4 inch backset with a square corner 1-1/8 x 2-1/4 inch faceplate, and it ships with the 10-025 ANSI strike, 1-1/4 x 4-7/8 inches with a 1-3/16 inch lip. If your frame already has an ANSI 4-7/8 inch strike cutout, the 10-025 drops straight in. A frame prepped for a T-strike or a smaller full-lip strike will need the existing strike reused or the frame reworked. 2-3/4 inch is the standard commercial backset; if your door is bored at 2-3/8 inches you need the matching latch instead.

5) What cylinder options does the ND80EU come in, and can I get it less cylinder to use my own keyway?

Five cylinder choices: P conventional 6-pin in the C keyway, L less conventional cylinder, B less Schlage FSIC cylinder, J less FSIC cylinder, and T FSIC construction core. The standard keyway is S123. If you are keying into an existing system, order one of the less-cylinder options (L, B, or J) and fit your own. The ND chassis carries three spring cage sets covering all Schlage formats plus eight competitive cylinder formats, so a non-Schlage cylinder is a supported build, not a workaround.

6) Is the Schlage ND80EU rated for a fire door?

Yes, UL/cUL listed for a 3-hour A label fire door on a 4 by 10 foot single or an 8 by 8 foot pair, and 90 minutes on 8 by 10 foot pair doors with the 3/4 inch latch option. It is ANSI/BHMA A156.2 Series 4000 Grade 1 certified, the electrified side meets A156.25 for indoor use, and it is ADA and ICC A117.1 compliant. It also meets the Buy American Act, which matters on federally funded work.

7) What is the difference between the electrified ND80EU and a plain mechanical storeroom lever?

Both are ANSI F86 storeroom: outside lever always locked, key gets you in, inside lever always free. The EU adds an electric release so the outside lever can also be unlocked from a card reader, intercom, or panel without anyone carrying a key. If nobody needs remote release at that opening, the mechanical ND80 does the same job with no wiring, no power supply, and no door cord. Specify EU only where a credential or a button has to open the door.

8) What is the closest Grade 1 electrified cylindrical lever lock to the Schlage ND80EU from another manufacturer?

The Corbin Russwin CL33903 is the nearest cross-brand equivalent in a Grade 1 electrified cylindrical lever lock, offered as a keyed 12VAC/DC electrified lever with a 1-3/4 inch to 2 inch door thickness range. The difference that decides the job is fail mode: the ND80EU is fail-secure, so the outside lever stays locked when power drops and the inside lever is always free for egress, while the CL33903 is a fail-safe lever that releases the outside lever on power loss. Specify the CL33903 only where the opening is intended to unlock on a power failure.

9) If an opening needs to unlock automatically when the fire alarm drops power, what should be used instead of the Schlage ND80EU?

The ND80EU is fail-secure, meaning the outside lever remains locked when current is removed, so it is the wrong choice for an opening that must free up on power loss. For that condition, the Corbin Russwin CL33903 is a Grade 1 fail-safe electrified cylindrical lever for 1-3/4 inch to 2 inch doors, which unlocks the outside lever when power is dropped. Both are Grade 1 cylindrical levers, so the door prep intent is the same; the fail mode is the deciding spec.

10) What is a lower-cost storeroom lever if the opening does not need electric release?

If the door only needs a key-operated storeroom function with no electrified release, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. Both give the storeroom function mechanically only. The ND80EU carries the same storeroom function at Grade 1 and adds the electric unlock, so it is the choice when an access control system or remote release has to drive the lever.

11) Do I have to specify a hand when ordering a Schlage ND80EU?

No handing to specify. The ND80EU is non-handed and installs on either swing, which is why property managers standardizing across a building can order one part number rather than tracking left and right at each opening.

12) How do I get a door position or request-to-exit signal back to the access control panel with a Schlage ND80EU?

The ND80EU is available with the Request to Exit function, which reports when the inside lever is turned so the panel does not read a legitimate exit as a forced door. RX is a plug-in module on the ND electrified chassis, and a Request To Exit switch for ND Series is available separately. Specify RX at order time if the panel needs that input.

13) I have a mix of high-traffic and low-traffic doors. Do I need ND80EU everywhere?

No. The ND Series is built for the abuse doors: 3,100 in-lb of lever torque, 1,600 lb of offset lever pull, 16 million cycles, and 100 hammer blows, all well past the BHMA Grade 1 minimums. On back-of-house or light-traffic openings, Schlage's ALX Series Grade 2 locks are made to pair with ND on mixed-grade projects so the levers and finishes still match. Cal-Royal's AG05 storeroom lever is another Grade 2 storeroom option, though it is mechanical only and will not take an electric release.

14) How many keys ship with a Schlage ND80EU, and can I key several locks alike?

Two nickel silver cut keys come with each lock on the P and P6 cylinder builds. Standard keying is KD, keyed different. Keyed alike is orderable when you want one key to run a group of storerooms, and there is a free-text field on the order for special cylinder or keying requirements if you are pinning into an existing masterkey system. For construction phasing, the T cylinder is an FSIC construction core you swap out at turnover.

15) Can the ND80EU be used on a classroom or exit device opening alongside other Schlage hardware?

It suites with Von Duprin exit devices and other Schlage products, so the levers and finishes line up across an opening that has an exit device on one door and a cylindrical lock on the next. For classroom use specifically, the ND Series offers indicator roses and the ND70 classroom function (ANSI F84); the ND80EU itself is a storeroom function and the outside lever stays locked, so it does not give a teacher a lockdown-from-inside option on its own.

16) Can I put a high security restricted key cylinder in a Schlage ND80EU?

Yes. High security is available with Primus XP cylinders, which are UL 437 listed, and the ND platform supports open, patented and restricted key systems. Worth knowing on the spec sheet: the beyond-Grade-1 performance figures apply with Schlage cylinders (conventional, FSIC and SFIC). With a non-Schlage cylinder the lock still exceeds BHMA Grade 1, just not to the Schlage-cylinder numbers.

17) Will a Schlage ND80EU fit a 1-3/8 inch door, and what storeroom lever covers thinner doors?

The ND80EU is built around a 1-3/4 inch door as its default thickness. Where a thinner leaf is involved, the Cal-Royal AG05 Grade 2 storeroom lever covers 1-3/8 inch to 1-3/4 inch and the Hager 2580 Grade 2 storeroom lock covers 1-3/8 inch to 2 inch. Note that neither of those is electrified, so a thin-door opening that also needs remote release is a different conversation than a thin-door opening that only needs a key.

18) Is the Corbin Russwin CL3110 an alternative to the Schlage ND80EU?

No. The CL3110 is a Grade 1 vandal resistant cylindrical lever in passage/closet function for 1-3/4 inch to 2 inch doors and it carries a fire rating, but passage function means the lever is always free from both sides. It has no cylinder and no electric control. The ND80EU is a keyed storeroom lock whose outside lever is continuously locked until released by key or electric current. The two share Grade 1 cylindrical lever construction and nothing about how the door secures.

19) What Grade 1 lever should be paired with a Schlage ND80EU on the non-secured doors of the same run?

Corridor and closet doors that need no locking can take a Grade 1 passage lever to match the duty level of the storeroom openings. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers covering 1-3/8 inch to 2-1/4 inch doors and carrying a fire rating, and the Falcon T101 is a Grade 1 heavy duty passage lever with pressure release technology. The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever for 1-3/4 inch doors. All three are unkeyed passage function; the ND80EU handles the doors that actually have to lock.

20) For a classroom or an asylum opening, what takes the place of the Schlage ND80EU?

Those are different ANSI functions and want different locks. The Dexter C1000 series covers Grade 1 classroom with a clutching keyed lever and Grade 1 classroom security, both for 1-3/8 inch to 1-3/4 inch doors, and a Grade 1 asylum F87 function for 1-3/8 inch to 2 inch doors. The ND80EU is the storeroom function: outside lever continuously locked, inside lever always free for egress. Use it where the door must stay secure at all times rather than be locked and unlocked by key from the corridor side.

21) Does an electronic keypad lever do the same job as a Schlage ND80EU?

No, they solve access differently. The Delaney LP250 is a Grade 2 electronic keypad leverlock and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for 1-1/8 inch to 2 inch doors; both grant entry from a code entered at the door and are standalone. The ND80EU is a Grade 1 keyed storeroom lock released by key or by electric current at 12V or 24V DC, which is what allows a card reader, intercom, or access control panel elsewhere in the building to unlock the door. If the release has to come from a system rather than from someone standing at the lever, the keypad units do not substitute.

22) Can a Schlage cylinder be carried across to Yale or Accentra hardware on the same key system?

Yes, with an adapter. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, which is how a facility keyed to Schlage keeps one key system when some openings run Accentra locks. The ND80EU itself accepts a range of cylinder formats including the S123 standard keyway, the C keyway conventional cylinder, FSIC, and an FSIC construction core, so the master key decision is made at the cylinder rather than at the lock body.

23) What is the difference between a Grade 1 and a Grade 2 storeroom lever for a high traffic back-of-house door?

The Cal-Royal AG05 and Hager 2580 both deliver storeroom function at Grade 2, the AG05 with a deadlocking latchbolt. The Schlage ND80EU delivers the same storeroom function at Grade 1 heavy duty with a zinc and steel body and an auxiliary latch that deadlocks the latchbolt when the door closes. Grade 1 is the higher ANSI/BHMA cycle and strength tier, which is the class typically specified for service corridors, loading areas, and mechanical rooms in institutional buildings; Grade 2 suits lighter traffic on the same function.

24) Is a Grade 2 entrance or office lever an acceptable substitute for a storeroom lock on a stockroom door?

It changes who can leave the door unlocked. The Hager 2525 Grade 2 commercial entry lever and the Falcon B511CP6D Grade 2 entry/office lever both allow the outside lever to be left unlocked by the occupant, and the Arrow HK11 turn-pushbutton entrance lock works the same way from a button in the inside knob. The ND80EU keeps the outside lever continuously locked until a key or electric current releases it, so it cannot be dogged open by whoever is in the room. On a stockroom or supply closet, that is the point of the function.

25) What finishes does the Schlage ND80EU electrified storeroom lever come in for matching existing hardware?

Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, and 643E aged bronze. 626 satin chrome is the usual commercial default. The 626AM antimicrobial option is the one to look at for healthcare and food service corridors where the rest of the building is already 626.

26) Is there a vandal-resistant version of the Schlage ND80EU for an exposed or public opening?

Vandlgard models are available in the ND Series, where the outside lever rotates freely when locked instead of taking the force of someone hanging on it. That is the option for exterior service doors and public corridors. If you want a cross-brand vandal-resistant Grade 1 cylindrical lever, the Corbin Russwin CL3110 is a vandal resistant Grade 1 lever for 1-3/4 to 2 inch doors, though it is passage/closet function with no keying and no electric release.

27) What is the Schlage ND80EU made of, and will it hold up in a high-traffic corridor?

Zinc and steel, heavy duty commercial construction. Lever stability comes from five points of engagement with no set screws or O-rings, which is why the cycle testing shows near-zero droop or wobble at 16 million cycles. Droop is the failure mode that gets levers replaced in apartment and school corridors, so that is the number to weigh against a lighter-duty lever.

28) What matching dummy trim goes on the inactive leaf of a pair where the active leaf has a Schlage ND80EU?

Dummy trim is unkeyed and non-operating, used to match appearance on an inactive leaf. In Grade 1 heavy duty, the BEST 9K series 1DT single dummy trim cylindrical lever and the Accentra 455LN Augusta Grade 1 single dummy lever both serve that role; the BEST 7KC series single dummy trim is the Grade 2 medium duty version. None of these lock or latch, so the securing function stays entirely with the ND80EU on the active leaf.

29) Can a residential Grade 3 lever be used on a commercial storeroom door instead of a Schlage ND80EU?

They are built for different service. The Kwikset 200BRNL Breton passage lever and 300BRNL Breton privacy lever are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AUS00 entrance/office lever is Grade 3 for the same range. The ND80EU is a Grade 1 heavy duty commercial lock in zinc and steel with storeroom function and electric release. On a commercial opening carrying a hardware schedule, the Grade 3 units do not answer the same specification.

30) Does the Corbin Russwin 585F715 lever work on a Schlage ND80EU?

No. The 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, a Corbin Russwin trim part for Corbin Russwin chassis. The ND80EU takes Schlage ND series lever designs, offered as Athens, Boardwalk, Broadway, Latitude, Longitude, Omega, Rhodes, Sparta, and Tubular. Order the lever style from the ND range rather than adapting exit device trim from another platform.

31) Are decorative brass leversets like the Baldwin 5103 or Emtek Classic an option for the same doors as a Schlage ND80EU?

They serve a different opening. The Baldwin Estate 5103 comes in passage, privacy, and handed half dummy versions, and Emtek Classic and Arts and Crafts leversets are offered as dummy pairs; those are residential-style trim functions with no storeroom keying and no electric release. The ND80EU is a commercial Grade 1 storeroom lock in architectural finishes including 626 satin chrome, 613 oil rubbed bronze, 622 matte black, and 643E aged bronze, so where the look matters on a commercial opening the finish choice lives inside the ND range.
