Accentra MO-5409LN-626 – Frequently Asked Questions

1) What does the Accentra 5409LN exit function actually do on the door?
The 5409LN Monroe is an exit-only lockset. There is no outside trim to operate the latch, so the door can always be opened from the inside by turning the lever, but there is no way in from the corridor side. It suits stair discharge doors, back-of-house exits, and any opening where free egress is required but outside entry is not wanted. If you need key entry from outside, you want a keyed function instead, not this one.
2) Does the 5409LN come with a 2-3/4 inch backset, and can I use it on a deeper stile?
Standard backset is 2-3/4 inches, which is the usual commercial bore. For deeper stiles or doors prepped further in, a 3-3/4 inch or 5 inch extension link can be ordered with the lock. Specify that at order time, it is not something you add later from the box.
3) Can I use this Accentra lever lock on a fire-rated door?
Yes. The 5409LN carries a UL/cUL fire rating up to 3 hours and is certified to ANSI/BHMA A156.2, Series 4000 Grade 1. It is also windstorm certified, though you should confirm against your local code for that application.
4) Will the 5409LN latch into the strike already in my frame?
Latchbolt throw is 1/2 inch stainless steel as standard, with a 3/4 inch throw available to order if your frame has a deeper strike pocket or a gap. The supplied strike is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and other lip lengths can be ordered to suit frame reveal. All strikes are reversible. Measure from the door stop to the center of the strike to pick the lip length.
5) Which lever lock alternatives fit a door thicker than 2 inches like the Accentra 5409LN Monroe does?
The Accentra 5409LN Monroe adjusts from 1-3/4 inch to 2-1/4 inch door thickness, which covers thick commercial and fire-rated leaves. Among the cylindrical lever comparables, the Falcon K101 Grade 1 passage lock is the one that also reaches 2-1/4 inch, listing 1-3/8 inch to 2-1/4 inch. Others stop short: the Corbin Russwin CL3110 Grade 1 passage lever covers 1-3/4 inch to 2 inch, the Hager 2525 Grade 2 entry lever covers 1-3/8 inch to 2 inch, and the Dexter C1000 classroom lever covers 1-3/8 inch to 1-3/4 inch. Measure the leaf before substituting.
6) What is the closest Grade 1 non-keyed cylindrical lever equivalent to the Accentra 5409LN Monroe exit lock?
The Accentra 5409LN Monroe is a Grade 1 cylindrical lever lock with an exit-only function, meaning the lever always retracts the latch and there is no keyed outside control. The closest Grade 1 non-keyed cylindrical lever alternatives are the Falcon K101, a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a fire rating, fitting doors 1-3/8 inch to 2-1/4 inch, the Falcon T101 Grade 1 heavy duty passage lever, the Dexter C1000 Grade 1 passage cylindrical lever with clutching levers, and the Corbin Russwin CL3110 Grade 1 vandal resistant passage/closet lever for 1-3/4 inch to 2 inch doors. All four operate free in both directions rather than exit-only from one side, so confirm which side of the opening needs blank trim.
7) The Accentra 5409LN has no outside key control - what should I use instead if the door needs to be locked and keyed?
The 5409LN Monroe is an exit-only function, so it is not the right choice where the outside must be secured by key. For a keyed cylindrical lever on the same style of opening, consider the Cal-Royal AG05 Grade 2 storeroom lever with a deadlocking latchbolt, the Hager 2580 Grade 2 storeroom lever with the Withnell lever for 1-3/8 inch to 2 inch doors, the Dexter C1000 Grade 1 classroom lever with clutching keyed levers, or the Dexter C1000 Grade 1 asylum (F87) lock for 1-3/8 inch to 2 inch doors where both sides are keyed. Match the keyway and keying to the rest of the facility before ordering.
8) Do I have to specify handing when ordering the Monroe 5409LN?
No. The 5409LN is non-handed and reversible, so one part number works on left or right hand doors. That is useful for property managers stocking spares, since a single lock covers every opening in the building regardless of swing.
9) Does the exit-only 5409LN have a cylinder or any keyed override?
The exit function has no outside operation, so key control is not part of this lock. Within the 5400LN Series, keyed functions come with a brass 6-pin keyed-random cylinder and two keys as standard, with 7-pin available to order. If you need the corridor side keyed for staff access, order a keyed function from the series rather than the 5409LN.
10) What else can I order with the 5409LN for a hospital or lab door?
Lead shielding is available to order on the 5400LN Series for X-ray room doors, and flat fronts can be substituted for the standard 2-1/4 x 1-1/8 inch beveled front where the door edge is square rather than beveled. Both are order-time options.
11) Is a Grade 2 lever lock good enough instead of the Accentra 5409LN?
Depends on traffic. Grade 1 to ANSI/BHMA A156.2 Series 4000 is the top commercial tier and is what belongs on stairwells, schools and high-cycle back-of-house doors. For lighter interior openings, Grade 2 options like the Hager 2510 passage lever (1-3/8 to 2 inch doors) or the Falcon B101 medium duty passage lever will serve. Do not step down on a fire-rated egress door where the spec calls Grade 1.
12) If Grade 1 is more than the opening needs, what is a lighter-duty alternative to the Accentra 5409LN Monroe lever lock?
The Accentra 5409LN Monroe is certified ANSI/BHMA A156.2 Series 4000 Grade 1 for high-traffic commercial use. For lower-traffic openings, Grade 2 cylindrical lever alternatives include the Falcon B101 medium duty Grade 2 passage lever with a non-handed design, the Design Hardware J75 Grade 2 passage lever for 1-3/4 inch doors, and the Hager 2510 Grade 2 passage lever with the Withnell design for doors 1-3/8 inch to 2 inch. Note that Grade 2 locks are tested to a lower cycle and strength threshold than Grade 1, so institutional specs calling out Grade 1 will not accept them.
13) Can the Accentra 5409LN Monroe lever be used as trim on a panic exit device?
No. The 5409LN Monroe is a complete cylindrical lever lock in the 5400 Series with its own latchbolt, and it mounts in a standard cylindrical door prep. Lever trim built for an exit device is a different part: the Corbin Russwin 585F715 is a Grade 1 lock lever made for the ED8000 pushpad exit device and the CL3300 cylindrical lock series, for doors 1-3/4 inch to 2 inch, and the Imperial USA ED-EL500HD is a heavy duty escutcheon lever trim with entry function in the ED-500 Series. Those attach to a rim or mortise exit device chassis, not to a bare cylindrical bore.
14) I need keyless code entry on this opening instead of the Accentra 5409LN Monroe - what are the options?
The 5409LN Monroe is a mechanical cylindrical lever with a brass 6-pin keyed cylinder as its standard credential, so it has no code entry. For pushbutton or keypad lever locks, the comparable set includes the Lockey 1150 heavy duty mechanical keypad lever set with double combination and passage function for doors 1-1/8 inch to 2 inch, the Lockey 2835DC double combination mechanical keyless lever lock for doors 1-3/16 inch to 2 inch, the Delaney LP250 Grade 2 electronic keypad leverlock, and the Emtek Classic keypad leverset. These change how the door is credentialed, so confirm fire-door and egress requirements for the opening before switching.
15) What is an electrified alternative if the opening controlled by the Accentra 5409LN Monroe needs access control?
The 5409LN Monroe is a purely mechanical Grade 1 cylindrical lever lock with no electrical option. Where the opening has to tie into an access control system, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever lock running on 12VAC/DC for doors 1-3/4 inch to 2 inch, offered with an NZ lever and D rose. Fail safe means the lever unlocks on loss of power, so verify that matches the egress and security intent for the door.
16) What should I use instead of the Accentra 5409LN Monroe on a bedroom or bathroom door that needs a thumbturn?
The 5409LN Monroe is an exit-only lever with no privacy locking, so it will not secure a restroom or bedroom door. Privacy-function alternatives in the set include the Hager 2540 Grade 2 privacy cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch, the Arrow MK02-TA Grade 2 privacy cylindrical lock with a Tudor knob, the Kwikset 300BRNL Breton Grade 3 privacy lever, and the Baldwin Estate 5103 privacy lever with the 5048 rose. Note the Arrow uses a knob rather than a lever, which matters where ADA lever operation is required.
17) What finishes does the Accentra Monroe 5409LN 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 outdoors and in coastal or high-touch areas than plated brass. 626 satin chrome is the usual commercial default if you are matching existing hardware.
18) What is the guardbolt on an Accentra 5400 Series lock for?
The guardbolt deadlocks the latchbolt whenever the door is closed, which stops someone carding or shimming the latch open. It comes standard on all locking functions in the series. On an exit-only opening that matters, because the outside face is the unsecured side.
19) I need a matching dummy lever on the inactive leaf of a pair, what do I use?
The 5409LN is a working exit lockset, not a trim. For the inactive leaf, use a dummy trim such as the BEST 9K Series 1DT single dummy, a Grade 1 heavy duty non-keyed trim, or the medium duty BEST 7KC Series 1DT if the leaf sees light use. Match the finish to the working leaf.
