Accentra YAL-MO-4730LN-626 – Frequently Asked Questions

1) What does the asylum function on the Accentra 4730LN actually do at the door?
The 4730LN is a double cylinder asylum/institution/utility lock, so there is a keyed cylinder on both sides and no free egress. The lever is locked from inside and outside at all times, and a key is required from either side to retract the latch. That is why it gets used on psychiatric and detention openings, utility and mechanical rooms. Do not put it on a required egress door unless your local code specifically allows a keyed-both-sides lock on that opening.
2) Will the Accentra 4730LN lever lock fit a 1-3/8 inch door?
Yes. The 4730LN is part of the 4700LN group, which adjusts from 1-3/8 inches through 1-3/4 inches. If your doors are thicker, 1-3/4 to 2 inches, that range belongs to the 4700 rather than the 4700LN, and the 4700 only comes in satin stainless steel 630.
3) What backset and latch throw does the 4730LN use, and will it latch into an existing ANSI strike?
Standard backset is 2-3/4 inches with a 1/2 inch stainless steel latchbolt throw, and an ANSI strike measuring 4-7/8 x 1-1/4 inches with 1-1/4 inch lip-to-center ships with the lock. If your frame already has a standard ANSI 4-7/8 inch strike prep at a 2-3/4 backset, the 4730LN drops straight in. An optional T-strike is available to order for the 4700LN if your frame is prepped that way.
4) Is the Accentra 4730LN fire rated and Grade 1?
It carries ANSI/BHMA A156.2, Series 4000, Grade 1 certification and is UL-cUL fire rated up to 3 hours. The 4700LN is also Windstorm certified, though you should check that against your local code for the opening in question.
5) What cylinders and keys come with the 4730LN, and can I get it 7-pin?
Each lock ships with brass 6-pin keyed-random cylinders and two keys. Since it is double cylinder, both sides are keyed. 7-pin is not offered in this series, so if your facility keys 7-pin you will need a different platform. Keyed-random means each lock has its own key out of the box; if you need these keyed alike or on a master system, that has to be specified with the order.
6) What is the closest Grade 1 equivalent to the Accentra 4730LN asylum lever lock from another brand?
The Dexter C1000 Series Asylum (F87) is the nearest match. Both are Grade 1 cylindrical lever locks with the Asylum/Institution/Utility function, meaning a keyed cylinder on each side with no free operation. The Dexter C1000 asylum is listed for doors 1-3/8 inch to 2 inch, while the Accentra 4730LN with the LN trim covers 1-3/8 inch to 1-3/4 inch and the 4700 body covers 1-3/4 inch to 2 inch. The Accentra carries UL-cUL fire ratings up to 3 hours and a 2-3/4 inch standard backset.
7) The door is 2 inches thick. What Grade 1 lever lock works if the 4730LN with LN trim will not?
The 4700LN trim adjusts from 1-3/8 inch to 1-3/4 inch, and the 4700 body covers 1-3/4 inch to 2 inch. For a 2 inch door in another line, the Falcon K101 Grade 1 passage lever is listed for 1-3/8 inch to 2-1/4 inch and the Corbin Russwin CL3110 Grade 1 vandal resistant passage lever is listed for 1-3/4 inch to 2 inch. Both of those are passage function only, so they do not replace the double cylinder keying of the 4730LN.
8) Do I need to specify handing when ordering the Accentra 4730LN?
No. The lock is non-handed and reversible, so one part number covers left and right hand openings. That is useful for a property manager or institution stocking spares, since a single lock covers every door in the building regardless of swing.
9) What keeps the latch from being carded or shimmed on the 4730LN?
A guardbolt is standard on all locking functions in the series. It deadlocks the latchbolt once the door closes, so the 1/2 inch stainless latch cannot be loided with a card or shim. That matters on utility and mechanical rooms where the lock is the only line of security on the opening.
10) What other Grade 1 asylum function cylindrical locks could I use instead of the Accentra 4730LN?
The Dexter C1000 Series asylum lock (F87) is the closest cross-brand equivalent we carry: Grade 1, asylum/institution/utility function, and it covers a wider door thickness range of 1-3/8 to 2 inches, which helps if your openings vary. If you can live with Grade 2, the Arrow MK33-BD-CS is a heavy duty asylum function lock with a ball knob rather than a lever, so it is not an option where lever hardware is required.
11) Can I standardize a whole building on the 4700LN series and still use different functions on different doors?
Yes, and that is the normal way it is specified. The 4730LN covers the asylum/institution/utility openings while the rest of the 4700LN series in the same Monroe lever design and the same finish covers classroom, storeroom and passage doors. You keep one lever design, one 2-3/4 inch backset and one ANSI strike prep across the facility, which keeps door prep and spare parts consistent.
12) What is the front size on the 4730LN latch, and can I get a flat front?
The standard front is 2-1/4 x 1-1/8 inches, beveled. Flat fronts are available to order, which is what you want on a door edge already mortised flat from previous hardware. If your existing latch front matches 2-1/4 by 1-1/8, the edge prep carries over with no patching.
13) We need key control on one side only, not both. What should be used instead of the 4730LN?
The 4730LN is a double cylinder asylum/institution/utility lock, keyed both sides. For single-side key control in a Grade 1 cylindrical lever, the Dexter C1000 Series Classroom is a Grade 1 classroom function lever for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 Classroom Security is a Grade 1 classroom security version over the same thickness range. In Grade 2, the Cal-Royal AG05 is a storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors and the Hager 2580 is a Grade 2 storeroom lever for 1-3/8 inch to 2 inch doors.
14) Can a Corbin Russwin CL33903 electrified lever be substituted for the Accentra 4730LN?
No, they solve different problems. The CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC with an NZ lever and D rose, for 1-3/4 inch to 2 inch doors, and it requires power and door wiring. The Accentra 4730LN is a purely mechanical double cylinder asylum lock with a brass 6-pin keyed-random cylinder and two keys furnished, needing no power at the opening.
15) For a utility closet in the same corridor, is there a simpler non-keyed lever that matches the Grade 1 spec?
For openings that do not need key control, the Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock that is fire rated and fits 1-3/8 inch to 2-1/4 inch doors, and the Dexter C1000 passage is a Grade 1 clutching non-keyed lever for 1-3/8 inch to 1-3/4 inch doors. The Accentra 4730LN is also non-handed but is keyed on both sides for institutional control, and is UL-cUL fire rated up to 3 hours.
16) Do residential-style levers like Kwikset or Baldwin work as a substitute on an institutional door?
They serve a different class of opening. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy levers are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Baldwin Estate 5103 is offered in passage, privacy and handed half dummy forms. The Accentra 4730LN is a commercial ANSI/BHMA A156.2 Series 4000 Grade 1 lock with a guardbolt, an ANSI 4-7/8 inch strike, and UL-cUL fire ratings to 3 hours for healthcare, correctional and educational use.
17) Is a keypad lever like the Lockey 2835 a workable alternative for a utility room?
Only if you want to remove keys from the opening entirely. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1 3/16 inch to 2 inch, and the 2835DC adds a double combination. The Accentra 4730LN instead uses a brass 6-pin keyed-random cylinder on both sides with two keys furnished, which is what lets it fold into an existing facility key system.
18) Our spec calls for a 2-3/8 inch backset. Does the 4730LN suit, or is there another lever to look at?
The Accentra 4730LN is supplied with a 2-3/4 inch standard backset. If the door is prepped at 2-3/8 inch, 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 for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal AG03 classroom lever in the same AG Series is built on the 2-3/4 inch backset like the Accentra.
19) What finishes does the Accentra 4730LN Monroe lever come in?
Eight choices: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, plus black suede and white suede powder coat. The suede powder coats are the ones to look at for healthcare and behavioral health interiors where a painted finish is specified; 626 satin chrome is the usual match for existing commercial door hardware.
20) Is the Accentra 4730LN heavy enough for a dormitory or correctional corridor?
It is built for that traffic. The mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated, and it holds ANSI/BHMA A156.2 Series 4000 Grade 1, the highest cylindrical lock grade. Typical placements are healthcare and psychiatric facilities, dormitories, correctional and detention centers, and government buildings.
21) Is a BEST 9K dummy trim lever an alternative to the 4730LN for a matching inactive leaf?
It is a companion, not a substitute. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever with no latch and no keying, used where a lever is wanted for appearance or pull only. The Accentra 4730LN is a working double cylinder lock with a 1/2 inch stainless steel latchbolt throw and a guardbolt that deadlocks the latch when the door closes. For a medium duty inactive leaf, the BEST 7KC Series 1DT is the Grade 2 dummy trim.
