Accentra YAL-AU-5318LN-626 – Frequently Asked Questions

1) What does the classroom security function on the Accentra 5318LN actually do?
The 5318LN is a double cylinder classroom security lock, which means there is a keyed cylinder on both sides of the door. A teacher locks or unlocks the outside lever with a key from inside the room without opening the door, and the inside lever always retracts the latch for free egress. That is the difference from a standard classroom lock, where locking requires stepping into the corridor to use the outside key.
2) Is the 5318LN a 2-3/4 inch backset lock, and can I get it for a 2-3/8 inch bore?
Standard backset is 2-3/4 inches, which is the usual commercial cylindrical prep. Extension links are available to order for 2-3/8 inch, 3-3/4 inch and 5 inch backsets, so a residential-depth 2-3/8 inch prep or a wide-rail aluminum door can both be handled, but the link has to be specified when you order.
3) Can I use this classroom lever on a fire-rated corridor door?
Yes. The Augusta 5318LN carries UL/cUL fire ratings up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 2 certified. It is also windstorm certified, though that one should be checked against your local code. Because the inside lever always frees the latch, egress is maintained on the classroom side.
4) Do I have to order the 5318LN handed for left or right hand doors?
No. The lock is non-handed and the latch front is universal for both flat and beveled door edges, so one part number covers either swing. The strike is reversible as well, which cuts what you have to keep on the shelf when you are standardizing a school.
5) Will the 5318LN latch into the strike already in my frame?
The latchbolt throws 1/2 inch in stainless steel, with a guardbolt that deadlocks it once the door closes. It ships with a 1-1/4 inch curved lip strike sized for a 1-3/4 inch door. If your existing frame has a deeper lip or a different cutout, other lip lengths are available to order, so match the lip to the frame reveal instead of forcing the supplied one.
6) We only need the key to unlock the outside lever, not a double cylinder - what is a simpler alternative to the 5318LN Augusta?
If the inside lever should always be free and the outside lever is simply key-controlled without a second inside cylinder, a standard classroom function lock is the simpler specification. The Cal-Royal AG03 classroom lever is a Grade 2 classroom lock with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, matching the 5318LN's 2-3/4 inch standard backset. The Dexter C1000 classroom lever is the Grade 1 equivalent of that same function. The Accentra 5318LN Augusta is the double cylinder classroom security version, which adds the inside cylinder so a teacher can lock the door from inside the room.
7) What is the closest classroom security lever lock to the Accentra 5318LN Augusta from another brand?
The Dexter C1000 Series classroom security cylindrical lever lock is the nearest match by function - it is also a keyed cylindrical lever lock built for the classroom security function, where the inside cylinder locks and unlocks the outside lever. The differences are grade and door range: the Dexter C1000 classroom security lock is Grade 1 with a clutching lever and fits doors 1-3/8 inch to 1-3/4 inch, while the 5318LN Augusta is ANSI/BHMA A156.2 Series 4000 Grade 2 and adjusts from 1-3/4 inch to 2 inch. If your doors are 2 inch thick, the Accentra covers them; if they are 1-3/8 inch, the Dexter does.
8) Our spec calls for Grade 1 on the classroom doors - what should we use instead of the Accentra 5318LN?
The 5318LN Augusta is certified to ANSI/BHMA A156.2 Series 4000 Grade 2, so it will not satisfy a Grade 1 requirement. In the Grade 1 cylindrical lever family, the Dexter C1000 Series classroom security lock carries a Grade 1 rating with the same classroom security function. The Corbin Russwin CL3100 Series is Grade 1 and fire rated for doors 1-3/4 inch to 2 inch, though the CL3110 is passage/closet function rather than keyed. Confirm the door thickness first: the Dexter C1000 classroom security lock is listed for 1-3/8 inch to 1-3/4 inch doors.
9) Can I use a Grade 2 storeroom lever like the Hager 2580 or Cal-Royal AG05 in place of the Accentra 5318LN Augusta?
Only if the opening does not need to be locked from the inside. The Hager 2580 with Withnell lever is a Grade 2 storeroom lock for doors 1-3/8 inch to 2 inch, and the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. On both, the outside lever is always locked and the key retracts the latch - there is no way to secure the door from within the room. The Accentra 5318LN Augusta is a double cylinder classroom security lock, which puts a keyed cylinder on both sides so the room can be locked down from inside.
10) Can the 5318LN be keyed into my existing master key system?
As furnished it comes with a brass 6-pin keyed-random cylinder and two keys, so out of the box it is not on your system. Keying has to be specified. Note that 7-pin cylinders are not offered in this lock, so if your facility standard is a 7-pin system this is not the lock to match it with.
11) Grade 1 or Grade 2 for a classroom security lock, and what are my options?
The Accentra 5318LN is Grade 2, which suits classroom and office doors with normal cycle counts. For a heavier opening, the Dexter C1000 Series classroom security lock is a Grade 1 clutching lever with the same function and fits 1-3/8 to 1-3/4 inch doors. If you need Grade 1 clutching in general, the Dexter C1000 family is the one to look at; if 2 inch doors are in play, the 5318LN covers that thickness and the C1000 does not.
12) I need matching passage and storeroom levers for the rest of the corridor. What pairs with a Grade 2 classroom lock?
Within Grade 2 cylindrical levers, the Hager 2580 with Withnell lever is a storeroom function for 1-3/8 to 2 inch doors, the Hager 2510 is the matching passage lever across the same thickness range, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt. Falcon B101 is another Grade 2 passage lever, non-handed. Lever design will not match Augusta across brands, so if visual consistency matters, keep the whole opening group in one series.
13) What is the difference between the Accentra 5318LN Augusta and a Grade 2 entrance/office lever like the Falcon B511CP6D or Hager 2525?
They share the Grade 2 rating but control the door differently. The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entrance/office function, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock for doors 1-3/8 inch to 2 inch - both typically lock the outside lever with a thumbturn or pushbutton and are meant for offices and tenant entries. The Accentra 5318LN Augusta is a classroom security lock with cylinders on both sides, so the room is locked and unlocked by key rather than by a turn button, which is what most school lockdown policies require.
14) We need a keyless code entry on a classroom door instead of the Accentra 5318LN - what are the options?
Keyless lever options in the same cylindrical footprint include the Delaney LP250 electronic keypad leverlock, which is Grade 2, and the mechanical Lockey 2835DC double combination keyless lever lock, which fits doors 1 3/16 inch to 2 inch and is a passage function. Note the function change: the Lockey 2835DC and 2835 are passage function, so they release freely once the code is entered, while the Accentra 5318LN Augusta is a keyed double cylinder classroom security lock. If lockdown control from inside the room is the requirement, a passage-function keypad will not deliver it.
15) For the non-locking doors in the same corridor, what pairs with the Accentra 5318LN Augusta?
For corridor and closet doors that never lock, a passage lever in the same Grade 2 class keeps the feel consistent: the Falcon B101 is a Grade 2 medium duty non-handed cylindrical passage lever, the Hager 2510 is a Grade 2 passage lever for doors 1-3/8 inch to 2 inch, and the Arrow GL01 is a Grade 2 passage cylindrical lock with Sierra lever for 1-3/4 inch to 2 inch doors. All are non-keyed. The Accentra 5318LN Augusta is also non-handed, so mixing these across an opening set does not introduce a handing question.
16) Will a residential Grade 3 lever like the Kwikset 200BRNL or Cal-Royal AUS00 work on our classroom doors?
Those are built for a different duty level. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors and the Cal-Royal AUS00 is a Grade 3 entrance/office lever for the same thickness range - neither offers a classroom security function. The Accentra 5318LN Augusta is a commercial Grade 2 lock certified to ANSI/BHMA A156.2 Series 4000 and UL/cUL fire rated up to 3 hours, which is what a labeled classroom door in an educational facility normally calls for.
17) What should I use instead of the Accentra 5318LN Augusta on a patient room or a door that needs no free egress trim?
For institutional openings that call for asylum function, where both levers are key-controlled and neither retracts the latch without a key, look at the Dexter C1000 Series asylum (F87) lock, which is Grade 1 and fits doors 1-3/8 inch to 2 inch, or the Arrow MK33-BD-CS asylum lock, a Grade 2 heavy duty unit with a conventional cylinder in Schlage C keyway and a ball knob rather than a lever. The Accentra 5318LN Augusta is a classroom security lock, so the inside lever always retracts the latch for egress.
18) Our access control plan needs the classroom lock tied to the card reader - is there an alternative to the Accentra 5318LN Augusta?
Yes, for an electrified opening look at the Corbin Russwin CL33903 fail safe cylindrical lever, available in 12VAC/DC and rated Grade 1 for doors 1-3/4 inch to 2 inch - the same door thickness range the 5318LN Augusta adjusts through. The Accentra 5318LN Augusta is a purely mechanical double cylinder lock, so it has no wiring path to a reader or access panel; use it where key control alone governs the room.
19) What finishes does the Accentra Augusta 5318LN come in?
Ten finish choices are orderable: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 693 black painted, plus black suede and white suede powder coat. PVD is standard on 605 and 606, which is what you want in a high-traffic school corridor where plated brass would wear through.
20) Can I get the Accentra 5318LN with lead shielding for an X-ray room door?
No. Lead shielding is not offered on the 5318LN, so it should not be specified for a radiology or imaging door that requires a lead-lined lock body.
21) How durable is the internal mechanism for a high-traffic school door?
The chassis is heavy-gauge steel, zinc-plated and dichromated for corrosion resistance, and the latchbolt is stainless steel. That is a commercial-duty build rather than a residential one, and it is backed by Grade 2 certification to ANSI/BHMA A156.2 Series 4000.
22) Is a privacy lever like the Hager 2540 or Arrow MK02-TA an acceptable substitute for the Accentra 5318LN Augusta?
No - privacy function locks are for restrooms and bedrooms, not secured classrooms. The Hager 2540 with Withnell lever is a Grade 2 lock listed for 1-3/8 inch to 2 inch doors, and the Arrow MK02-TA is a non-keyed privacy cylindrical lock with a Tudor knob. Neither is keyed, so there is no key override and no way to control the room on a master key system. The Accentra 5318LN Augusta is keyed with brass 6-pin cylinders and two keys furnished standard.
23) We need matching inactive trim on the paired classroom doors alongside the Accentra 5318LN Augusta - what do I order?
Dummy trim is the right item for an inactive leaf, since it mounts a fixed lever with no latch. The BEST 7KC Series single dummy trim is a Grade 2 medium duty cylindrical lever dummy, and the BEST 9K Series 1DT single dummy trim is the Grade 1 heavy duty version. The Callan Bentley is another Grade 2 dummy lever. These carry no cylinder and no latchbolt, unlike the Accentra 5318LN Augusta, which is a keyed double cylinder lock with a 1/2 inch stainless steel latchbolt and guardbolt.
