Accentra AU-5430LN-626 – Frequently Asked Questions

1) What does the asylum function on the Accentra 5430LN lever lock actually do?
The 5430LN Augusta is an asylum/institution/utility function lock, which means it is keyed on both sides and there is no free egress from either lever. Both levers stay locked until a key is turned, so the door can only be operated by someone carrying a key. That is why it shows as a double cylinder keyed function. Do not put it on a required egress door; for a door people must exit through without a key, use a storeroom or classroom function instead.
2) Will the Accentra 5430LN fit a 2 inch thick door?
Yes. The 5430LN Augusta cylindrical lock adjusts from 1-3/4 inches up to 2-1/4 inches of door thickness, so a 2 inch door is inside the range with no extra parts. What it will not do is drop onto a 1-3/8 inch door, which is common on older interior openings. For those, the Dexter C1000 asylum lock (F87) covers 1-3/8 inches to 2 inches.
3) What backset does the 5430LN use, and can it work on a door bored for a deeper backset?
Standard is a 2-3/4 inch backset, the usual commercial bore. If the door is prepped deeper, extension links for 3-3/4 inch or 5 inch backsets are available to order, so wide stiles and unusual preps can be covered, but the extension has to be specified on the order.
4) Will the 5430LN latch into the strike already in my frame?
Standard latchbolt throw is 1/2 inch stainless steel, with a 3/4 inch throw available to order for frames with a deeper gap or a wider strike pocket. The strike supplied as standard is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and other lip lengths can be ordered if your frame reveal needs it. All strikes are reversible. A guardbolt deadlocks the latch once the door closes.
5) Is the Accentra 5430LN rated for a fire door?
It is UL/cUL fire rated up to 3 hours and certified to ANSI/BHMA A156.2, Series 4000, Grade 1. It is also windstorm certified, subject to local code. The deadlocking guardbolt is standard on all locking functions, which is what keeps the latch secured in a fire-rated opening.
6) What is the closest Grade 1 equivalent to the Accentra 5430LN Augusta asylum lever lock from another brand?
The Dexter C1000 Series asylum lock, function F87, is the closest match. Both are Grade 1 cylindrical locks with asylum/institution/utility function. The difference is the door thickness they cover: the Accentra 5430LN adjusts from 1-3/4 inch to 2-1/4 inch, while the Dexter C1000 asylum lists 1-3/8 inch to 2 inch. On a thin 1-3/8 inch door the Dexter is the one that fits; on a 2-1/4 inch institutional door the Accentra is.
7) Is there a lighter duty asylum lever lock instead of the Accentra 5430LN?
The Arrow MK33-BD-CS is the step down. It is a Grade 2 heavy duty asylum function cylindrical lock, but it uses a ball knob rather than a lever and comes with a conventional cylinder in the Schlage C keyway. The Accentra 5430LN is Grade 1 with the Augusta lever, so if ADA lever operation or Grade 1 certification is called out on the drawing, the Arrow will not satisfy it.
8) The opening does not need key control on both sides. What should I use instead of the Accentra 5430LN?
The 5430LN is a double cylinder asylum function lock, keyed on both sides. If only one side needs a key, a storeroom function lock such as the Hager 2580 with Withnell lever, a Grade 2 storeroom for 1-3/8 inch to 2 inch doors, or the Cal-Royal AG05, a Grade 2 storeroom lever with deadlocking latchbolt, covers the opening. For a classroom function, the Dexter C1000 classroom is Grade 1. For no key at all, the Falcon K101 is a Grade 1 fire-rated passage lock covering 1-3/8 inch to 2-1/4 inch doors.
9) Do I need to specify handing when ordering the Accentra 5430LN Augusta lever?
No handing to call out. The 5430LN is non-handed and fully reversible, and the strike is reversible as well, so one part number covers left and right hand openings. For a property manager standardizing across a building, that means a single SKU per finish on the shelf.
10) What cylinder and keying comes with the 5430LN, and can it go on my existing key system?
As furnished, it carries a brass 6-pin keyed-random cylinder with two keys. A 7-pin cylinder is available to order, and other cylinder and keying options are listed in the manufacturer catalog. Since this is an asylum function, it takes a cylinder on both sides, so keying has to be specified for both.
11) What are the front and door prep dimensions for the 5430LN?
The standard front is 2-1/4 x 1-1/8 inches, beveled; flat fronts can be ordered if the edge prep calls for it. The chassis is heavy-gauge steel, zinc plated and dichromated, and the lock thrubolts through the door. Lead shielding is available to order for X-ray rooms in healthcare work.
12) What other asylum function locks could I use instead of the Accentra 5430LN?
Two comparable asylum function locks: the Dexter C1000 Series asylum (F87) is Grade 1 and covers 1-3/8 inch to 2 inch doors, which is the one to reach for on thinner doors. The Arrow MK33-BD-CS is a heavy duty Grade 2 asylum lock with a ball knob and a conventional Schlage C keyway cylinder, so it suits a building already keyed to Schlage C, though it is a knob rather than a lever.
13) Can I use a Grade 1 passage lever in place of the Accentra 5430LN on an institutional door?
Only where that leaf does not need to be secured. The Accentra 5430LN is keyed on both sides with asylum function. Grade 1 passage levers such as the Corbin Russwin CL3110 vandal resistant passage, the Falcon T101 with pressure release, or the Dexter C1000 passage are non-keyed and latch only. They match the Grade 1 rating but give no key control, so they suit corridor and closet leaves rather than the secured opening the 5430LN is specified for.
14) What looks like a substitute for the Accentra 5430LN but is not?
Two categories get ordered by mistake. Dummy trims such as the BEST 9K Series 1DT, a Grade 1 heavy duty single dummy, carry the same grade and lever appearance but have no latch and no cylinder at all. And keypad leversets such as the Lockey 2835 or the Delaney LP250 replace the key with a code; they are not double cylinder asylum function locks. Where the spec calls for asylum function with a key on each side, the 5430LN Augusta is what meets it.
15) I need an electrified lever on the same institutional doors as the Accentra 5430LN. What is available?
The Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC, with the NZ lever and D rose, for doors 1-3/4 inch to 2 inch thick. It holds the same Grade 1 rating as the Accentra 5430LN but is access-control driven rather than purely mechanical, and it does not reach the 2-1/4 inch door thickness the 5430LN adjusts to.
16) What finishes does the Accentra 5430LN Augusta lever come in?
Nine 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, plus BSP black suede powder coat and WSP white suede powder coat. PVD is standard on 605 and 606, which holds up better than lacquer in high-touch institutional corridors.
17) I need a lever lock on the same doors but without keyed locking. What pairs with the 5430LN?
For passage openings in the same building, the Falcon K101 is a Grade 1 non-keyed passage cylindrical lock with non-handed levers, fire rated, and it covers 1-3/8 inch to 2-1/4 inch doors, the same upper thickness as the 5430LN. The Corbin Russwin CL3110 is another Grade 1 passage option, vandal resistant and fire rated, for 1-3/4 inch to 2 inch doors.
