Accentra AU-5490LN-626 24V – Frequently Asked Questions

1) Will the Accentra 5490LN electrified lever lock fit a 2-inch thick door?
Yes. The 5490LN is adjustable from 1-3/4 inch up to 2-1/4 inch door thickness, so a 2 inch door is inside its range with no extra parts. Below 1-3/4 inches it is out of range. Standard backset is 2-3/4 inches, with 3-3/4 inch or 5 inch extension links available to order if the door is prepped deeper.
2) What voltage does the 5490LN electrified lock come in?
Two voltages are offered on the 5490LN: 12V and 24V. Every finish offered is available in both, so pick the one matching your power supply and access control panel output before you order.
3) Do I need to specify handing for the Accentra 5490LN lever lock?
No. The 5490LN is non-handed, and the strikes are reversible as well. One part covers left and right hand openings, which is why it works well when you are standardizing hardware across a building and do not want to stock two versions.
4) Is the 5490LN lever lock approved for fire doors?
It is UL/cUL fire rated up to 3 hours and meets ANSI/BHMA A156.2 Series 4000 Grade 1. It is also windstorm certified, though local codes govern that application. That combination covers most fire rated corridor, stair and cross-corridor openings in schools, hospitals and government buildings.
5) Will the 5490LN latch into the strike I already have in the frame?
Standard latchbolt throw on the 5490LN is 1/2 inch stainless steel, with a 3/4 inch throw available to order. The furnished strike is a 1-1/4 inch curved lip sized for a 1-3/4 inch door; other lip lengths can be ordered if your frame is set back further. If the existing frame prep is ANSI 4-7/8 inch with a deeper pocket, the 3/4 inch throw is the safer call.
6) Can I use the 5490LN on a 1-3/8 inch interior door?
No. The 5490LN starts at 1-3/4 inches and will not adjust down to 1-3/8. For a 1-3/8 inch door in a commercial setting, the Falcon K101 Grade 1 passage lock covers 1-3/8 inch to 2-1/4 inch, and the Dexter C1000 classroom and passage levers cover 1-3/8 inch to 1-3/4 inch. Note those are mechanical, not electrified.
7) What is the closest equivalent to the Accentra 5490LN electrified cylindrical lever lock from another brand?
The Corbin Russwin CL33903 is the closest match. It is a Grade 1 fail safe electrified cylindrical lever lock rated for 12VAC/DC with a door thickness range of 1-3/4 inch to 2 inch. The Accentra 5490LN is also a Grade 1 electrified cylindrical leverset, offered in 12V and 24V, and adjusts for 1-3/4 inch to 2-1/4 inch doors, so it covers thicker doors and gives you a 24V option where the CL33903 is specified at 12VAC/DC.
8) Can a keypad leverset replace the Accentra 5490LN for standalone access control?
They solve different problems. The 5490LN is an electrified cylindrical lever in 12V and 24V, meaning it is wired back to an access control system. The Lockey 2835 is a mechanical pushbutton keyless lever with passage function for 1-3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Those run standalone at the door with no power run, so choose them when there is no wiring to the opening and no central credential system.
9) What looks like a substitute for the 5490LN but will not work on a commercial fire-rated opening?
Residential and light-commercial leversets are the trap. The Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, the Cal-Royal AUS00 entrance/office lever is Grade 3, and the Callan Artino is a Grade 3 entrance leverset. The Accentra 5490LN is Grade 1 to ANSI/BHMA A156.2 Series 4000 and UL/cUL fire rated up to 3 hours, which is what a commercial fire-rated door schedule calls for.
10) What keying comes with the Accentra 5490LN and can I key it into my existing system?
Standard is 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 offered through the 5400LN series catalog, so it can be brought into a masterkey system rather than left keyed random.
11) What finishes does the Accentra 5490LN Augusta lever come in?
Nine finishes 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, BSP black suede powder coat and WSP white suede powder coat. PVD is standard on 605 and 606, which holds up better on exterior and high-traffic entries than plated brass. The trim is the Augusta lever design.
12) I just need a heavy-duty lever on a non-electrified opening. Is there a simpler option than the 5490LN?
Yes, and you should not pay for an electrified chassis you will not wire. For Grade 1 mechanical lever locks, the Falcon K101 is a non-keyed Grade 1 passage lever with a fire rating that fits 1-3/8 inch to 2-1/4 inch doors, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 inch to 2 inch doors. Keep the 5490LN for openings tied into access control.
13) Is there a lighter-duty keyed lever I can use instead of the 5490LN on interior office doors?
Yes. The Hager 2525 is a Grade 2 commercial cylindrical entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Both are mechanical Grade 2 sets, a step down from the Grade 1 Accentra 5490LN, and neither carries an electrified function.
14) I need a classroom or storeroom function on the same door schedule as the 5490LN. What are my options?
For non-electrified functions on the same schedule, the Dexter C1000 is available in Grade 1 classroom and Grade 1 classroom security, both clutching and keyed, for 1-3/8 inch to 1-3/4 inch doors, and in Grade 1 asylum (F87) for 1-3/8 inch to 2 inch doors. The Cal-Royal AG03 is a Grade 2 classroom lever with a 2-3/4 inch backset, matching the 2-3/4 inch standard backset of the Accentra 5490LN.
15) What does the guardbolt on the 5490LN do?
The guardbolt deadlocks the latchbolt whenever the door is closed, which blocks loiding (carding the latch back). It is standard on all locking functions in the 5400LN line, so you are not adding it as an option.
16) What front is supplied with the Accentra 5490LN latch, and can I get a flat one?
Standard is a 2-1/4 inch by 1-1/8 inch beveled front. Flat fronts are available to order, which is what you want when the existing door prep was cut for a flat face latch and you do not want to patch the edge. Lead shielding is also available to order for radiology and imaging rooms.
17) Will a Grade 1 dummy or passage trim work in place of the 5490LN where there is no latching required?
For an opening with no latching, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, and the Dexter C1000 is a Grade 1 clutching passage cylindrical lever for 1-3/8 inch to 1-3/4 inch doors. Neither is keyed or electrified, so they do not carry any access control or locking function the way the Grade 1 electrified Accentra 5490LN does.
