Accentra YAL-PB-4790LN-626 – Frequently Asked Questions

1) Will the Accentra 4790LN fit a 1-3/4 inch commercial door?
Yes. The 4790LN Pacific Beach lever lock is adjustable from 1-3/8 to 1-3/4 inch door thickness, so it covers both the standard 1-3/4 inch commercial leaf and older 1-3/8 inch interior doors. If your door is thicker, 1-3/4 to 2 inches, that is the 4700 (non-LN) chassis instead, and that version comes only in satin stainless steel 630.
2) What backset and strike does the 4790LN electrified lever lock use?
It is prepped for a 2-3/4 inch backset as standard and ships with an ANSI strike measuring 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. The latchbolt is stainless with a 1/2 inch throw, so if your frame already has an ANSI 4-7/8 prep it will latch without frame work. An optional T-strike can be ordered for the 4700LN if your frame is prepped that way.
3) What does fail safe mean on this electrified lever lock, and when should I pick it?
Fail safe means the outside lever is unlocked when power drops. Cut the power, or pull the fire alarm tied to the access control, and the door becomes free egress and free entry from both sides. That is what you want on stair re-entry doors and doors that have to release on alarm. If you need the door to stay locked in a power failure, you want a fail secure version, not the 4790LN.
4) Is the Accentra 4790LN approved for a fire rated door?
The lock is UL-cUL fire rated up to 3 hours and certified to ANSI/BHMA A156.2, Series 4000, Grade 1. It also carries 4700LN windstorm certification, though you should verify against local code for your jurisdiction. Note that with fail safe electrified hardware on a fire door, the release scheme has to be coordinated with your fire alarm and access control design.
5) What cylinder and keys come with the 4790LN, and can I get it 7-pin?
It comes with a brass 6-pin keyed-random cylinder and two keys as standard. A 7-pin cylinder is not offered on this lock, so if your facility is standardized on a 7-pin master key system this chassis will not accept it and you will need a different platform.
6) What is the closest cross-brand equivalent to the Accentra 4790LN fail safe electrified lever lock?
The Corbin Russwin CL33903 is the nearest match: it is a Grade 1 fail safe electrified cylindrical lever lock, offered with a 12VAC/DC coil and an NZ lever on a D rose. The main difference to check before you order is door thickness. The Accentra 4790LN adjusts from 1-3/8 inch to 1-3/4 inch, while the CL33903 covers 1-3/4 inch to 2 inch, so on a 1-3/8 inch door the 4790LN is the one that fits and on a 2 inch door the Corbin Russwin is.
7) Do I need to order the 4790LN handed left or right?
No. The 4700LN chassis is non-handed and reversible, so one lock covers both left and right hand openings. That is useful for a property manager stocking spares across a building, since you do not have to carry two part numbers. The guardbolt deadlocks the latchbolt whenever the door is closed.
8) What else do I need besides the lock to get an electrified lever lock working on the door?
The lock itself is the last piece. You still need a power supply matched to the lock's voltage, a transfer path for the wire into the door (an electric hinge or door loop), and whatever controls the release, a card reader or access control panel with its relay. Power gets pulled before install, the wiring is run per the manufacturer's diagram, and the fail safe release is tested end to end before sign-off.
9) What is the front size on the 4700LN latch, and can I get a flat front?
A 2-1/4 x 1-1/8 inch beveled front is standard. Flat fronts are available to order, which is what you need when the existing door edge is prepped flat rather than beveled, so you can drop the lock in without re-mortising the edge.
10) I do not need access control on this door. What Grade 1 cylindrical lever should I use instead?
Skip the electrified chassis if nothing is controlling the door. For a Grade 1 mechanical lever in the same cylindrical format, the Dexter C1000 Series covers classroom, classroom security and passage functions on 1-3/8 to 1-3/4 inch doors, and the Falcon K101 is a Grade 1 fire rated passage lever with a wider 1-3/8 to 2-1/4 inch thickness range. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever for 1-3/4 to 2 inch doors.
11) Is a standalone keypad lever a substitute for this electrified lock?
Not for a networked opening. Keypad levers like the Lockey 2835 or the Delaney LP250 run standalone, with no wiring and no panel, so they cannot be released by an access control system or dropped open on a fire alarm the way a fail safe electrified lock can. Use a keypad lever where you just want code-based entry on an isolated door. Use the 4790LN where the door has to answer to a reader or a central system.
12) Is a keypad lever like the Lockey 2835 or Delaney LP250 a substitute for the 4790LN?
No. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function that fits 1 3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both grant access at the door by code. The Accentra 4790LN is a Grade 1 fail safe electrified lock whose release is driven by a wired access control system, so it unlocks when power is removed and reports to the panel. If the requirement is credential control at a head end, the keypad units do not replace it.
13) What is a lower-cost lever for a back-of-house door where Grade 1 electrified is more than the opening needs?
For a non-electrified secondary opening, the Cal-Royal AG05 is a Grade 2 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 with a Withnell lever for 1-3/8 inch to 2 inch doors. Both are keyed mechanical locks and give up the fail safe electrified release and the Grade 1 certification of the Accentra 4790LN.
14) What finishes does the Accentra Pacific Beach 4790LN come in?
Eight finish choices: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, plus BSP black suede powder coat and WSP white suede powder coat. The two suede powder coats are the ones to look at when you are matching painted storefront or dark bronze entry hardware rather than plated trim.
15) How is the 4790LN chassis built for high traffic openings?
The mechanism is heavy-gauge steel, die-cast, zinc-plated and chromated, and it is certified to ANSI/BHMA A156.2 Grade 1, the heaviest cylindrical grade. That is the spec level intended for school corridors, hospital wings, and high-turnover multi-tenant entries rather than light-duty interior doors.
16) Can I use the Corbin Russwin 585F715 lever in place of the 4790LN?
No. The 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device in the CL3300 cylindrical lock series, so it is trim rather than a complete cylindrical lockset. The Accentra 4790LN is a full electrified cylindrical lever lock with latch, guardbolt and ANSI strike.
17) For an inactive leaf next to the electrified 4790LN opening, what dummy trim matches in duty level?
The BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed cylindrical lever dummy, which sits at the same certification level as the Grade 1 Accentra 4790LN. The BEST 7KC 1DT single dummy is the Grade 2 medium duty alternative if the inactive leaf sees light use.
18) We standardize on Grade 1 passage levers for corridors - which peer pairs with the 4790LN on secured doors?
The Falcon T101 is a Grade 1 heavy duty cylindrical passage lever with pressure release technology, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever lock with a fire rating for 1-3/4 inch to 2 inch doors. Either keeps the corridor doors at Grade 1 while the Accentra 4790LN handles the openings that need fail safe electrified release.
