Accentra AU5407LN 626 LESS 1210 – Frequently Asked Questions

1) What backset does the Accentra AU540 lever lock use, and will it drop into my existing door prep?
The AU540 is a 2-3/4 inch backset lock, which is the standard commercial bore location. It is a cylindrical lockset, so it goes into a standard cylindrical prep. If the doors in your building were bored at 2-3/8 inches (the common residential backset), the cross bore will not line up.
2) Will the Accentra AU540 latch into the strike already in my frame?
It ships to the ANSI strike standard, 4-7/8 x 1-1/4 x 1-1/4 inches, with a 1/2 inch latch throw. If your frames are already prepped for a full ANSI 4-7/8 inch strike, which is typical of hollow metal commercial frames, the AU540 drops straight in. Frames cut for a small T-strike or a round corner residential strike will need the prep opened up.
3) Can the Accentra AU540 go on a fire rated door?
Yes. The AU540 Augusta lever lock is UL listed for 3 hour fire doors, so it is usable on rated openings up to a 3 hour label. That listing plus the ANSI/BHMA Grade 1 certification is what most institutional and healthcare specs are looking for on a corridor or stair door.
4) Which lock function should I order on the Accentra AU540 Augusta lever?
Three functions are offered: Entry, Storeroom, and Classroom. Storeroom keeps the outside lever locked at all times and the key retracts the latch, which is what you want on mechanical rooms and supply closets. Classroom is locked and unlocked by key from the outside only, with no inside button. Entry is the general office and tenant door function. All three come on the Augusta (AU) lever in 626 satin chrome.
5) Can the Accentra 5400 Series lever be electrified for an access control system?
Yes. The 5400 Series carries a self-contained continuous duty integral solenoid that installs in a standard cylindrical prep, so you do not need a special door cutout. Specify fail safe or fail secure, and 12 or 24 volts DC. It uses an 8 position ElectroLynx plug connector, and an external rectifier is available on request if you have to run it on AC.
6) What is the closest Grade 1 cylindrical lever alternative to the Accentra AU540 Augusta for a 1-3/4 inch to 2 inch door?
The Accentra AU540 Augusta is a Grade 1 cylindrical lever lock rated for doors 1-3/4 inch to 2 inch thick. Among Grade 1 cylindrical levers covering that same 1-3/4 inch to 2 inch door range, the Corbin Russwin CL3110 from the CL3100 series is the nearest match on chassis class and door thickness, though it is a passage/closet function rather than a keyed entrance lock. Falcon's K101 in the K series is also Grade 1 and covers an even wider 1-3/8 inch to 2-1/4 inch door range, again in passage function. If the opening needs to be keyed, stay with the AU540, which is a keyed single-cylinder lock.
7) What should I use instead of the Accentra AU540 Augusta on a door thinner than 1-3/4 inch?
The Accentra AU540 Augusta covers doors 1-3/4 inch to 2 inch thick, so a thinner leaf needs a different chassis. The Dexter C1000 classroom lever is Grade 1 and covers 1-3/8 inch to 1-3/4 inch, and the Dexter C1000 asylum function covers 1-3/8 inch to 2 inch. The Falcon K101 Grade 1 passage lever spans 1-3/8 inch to 2-1/4 inch. On the Grade 2 side, the Hager 2510 passage lever and Hager 2525 entry lever both cover 1-3/8 inch to 2 inch.
8) Can a Kwikset or Callan lever be used as a substitute for the Accentra AU540 Augusta on a commercial opening?
They are not equivalent. The Accentra AU540 Augusta is a Grade 1 commercial cylindrical lock UL listed for 3 hour fire doors. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 and cover 1-3/8 inch to 1-3/4 inch doors, the Callan Artino and Callan Bennett entrance leversets are Grade 3, and the Cal-Royal AUS00 entrance/office lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors. Those suit residential and light interior use rather than a Grade 1 commercial specification.
9) What looks like a substitute for the Accentra AU540 Augusta lever but will not work on the same door?
Several levers in the same size class are not interchangeable with the Accentra AU540 Augusta, which is a keyed cylindrical entrance lever with a 2-3/4 inch backset. Dummy trim such as the BEST 9K 1DT, the BEST 7KC 1DT, the Baldwin Estate 5103 half dummy and the Emtek Cortina dummy pair have no latch at all and only mount as pull trim. The Corbin Russwin 585F715 is lever trim for an ED8000 pushpad exit device, not a standalone lockset. And knob designs such as the Arrow MK02-TA privacy and Arrow MK33-BD-CS asylum are knobs rather than levers, which matters where lever operation is required.
10) The Accentra AU540 Augusta comes in a 2-3/4 inch backset. What if my doors are prepped for 2-3/8 inch?
The Accentra AU540 Augusta is specified with a 2-3/4 inch backset and an ANSI strike of 4-7/8 inch by 1-1/4 inch by 1-1/4 inch. For a 2-3/8 inch prep, the Cal-Royal AG00 entrance lever is a Grade 2 lock with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset. Within the same Cal-Royal AG series, the AG03 classroom lever is built on a 2-3/4 inch backset if part of the job matches the AU540 prep.
11) Is the Accentra AU540 heavy duty enough for a school or hospital corridor?
It is built for exactly that traffic. Grade 1 is the top ANSI/BHMA commercial durability tier, and the Augusta lever uses a free wheeling mechanism so that when the lock is secured the outside lever spins rather than transferring force into the chassis. That, with wear resistant chassis plates and heavy duty return springs, is what keeps it alive on high abuse openings in schools, healthcare, and multi-tenant buildings.
12) Is the Accentra AU540 keyed, and what cylinder options work with it?
Keyed, single cylinder, with a key outside and no key inside. Cylinder choices are the full 5400LN range, and there is a mechanical cylinder override on the electrified versions so a key still gets you in if the power or the access control system is down.
13) What else could I use instead of the Accentra AU540 if I need a Grade 1 electrified cylindrical lever?
The Corbin Russwin CL33903 is the closest cross-brand match: Grade 1, fail safe, 12VAC/DC, and the same 1-3/4 to 2 inch door thickness range. Difference is the trim, the CL33903 comes with the NZ lever on a D rose rather than the Augusta lever. If you need a Grade 1 non-keyed lever on the same doors to match the look, the Corbin Russwin CL3110 passage is vandal resistant and covers the same 1-3/4 to 2 inch thickness.
14) Is the Accentra AU540 a mortise lock or a bored cylindrical lock?
Bored cylindrical. It installs through a cross bore in the door face rather than a routed mortise pocket in the edge, with a 2-3/4 inch backset. If your doors are prepped for a mortise case, this lock will not go in them.
15) Is there a lighter-duty lever lock to use instead of the Accentra AU540 Augusta on low-traffic interior doors?
The Accentra AU540 Augusta is built to ANSI/BHMA Grade 1 for commercial openings. Where the traffic does not warrant Grade 1, Grade 2 cylindrical levers cover the same basic openings: the Hager 2525 is a Grade 2 commercial entry lever for doors 1-3/8 inch to 2 inch, the Hager 2580 with Withnell lever is a Grade 2 storeroom lock over the same door range, and the Falcon B511CP6D is a Grade 2 entry/office lever. The Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch.
16) Is there a keyless pushbutton lever I can use instead of the Accentra AU540 Augusta to avoid issuing keys?
The Accentra AU540 Augusta is a keyed single-cylinder lock, so every user needs a key. To run an opening on a code instead, the Lockey 1150 is a heavy duty mechanical keypad lever set for doors 1-1/8 inch to 2 inch, the Lockey 2835 is a mechanical pushbutton keyless lever lock for 1-3/16 inch to 2 inch doors in passage function, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. These change how the door is accessed rather than matching the AU540's keyed function.
17) Which alternatives to the Accentra AU540 Augusta carry a fire rating for a rated opening?
The Accentra AU540 Augusta is UL listed for 3 hour fire doors. If a different function is needed on a rated opening, the Corbin Russwin CL3110 vandal resistant passage lever is Grade 1 and fire rated over the same 1-3/4 inch to 2 inch door range, and the Falcon K101 Grade 1 passage lever is fire rated across 1-3/8 inch to 2-1/4 inch doors. Verify the specific rating required by the opening against each product's listing before ordering.
18) I need classroom and storeroom functions on the same job as the Accentra AU540 Augusta. Do I have to change brands?
No. The Accentra AU540 Augusta is offered in Storeroom, Entry and Classroom functions in 626 satin chrome with the AU lever, so a mixed-function corridor can be covered on one chassis and one lever style. If a job calls for functions beyond those, the Dexter C1000 series adds classroom security and asylum functions in Grade 1, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt.
19) What finish does the Accentra Augusta lever come in?
626 satin chrome, on all three functions. That is the standard commercial finish, so it will sit alongside most existing satin chrome closers, hinges, and exit hardware in an office or institutional building without a mismatch.
