Accentra PB-4780LN-626 12V – Frequently Asked Questions

1) What does fail safe with no override mean on the Accentra 4780LN electrified lever lock?
Fail safe means the outside lever unlocks when power is removed, so a power loss or a fire alarm release leaves the opening free to enter. Power applied keeps it locked. No override means there is no key cylinder in the outside lever to defeat that state mechanically, so access control alone governs the outside trim. Inside lever is always free for egress. If you need a key to get in when the system is down, this is the wrong variant, choose a keyed electrified function instead.
2) Is the Accentra 4780LN available in 12V or 24V?
Both. Every finish is offered in a 12VDC and a 24VDC build, and voltage is a build option on the lock, not a field change, so match it to the power supply feeding the opening before you order. A 24VDC lock on a 12V supply will not pull.
3) Will the 4780LN drop into my existing 2-3/4 inch backset prep and strike?
Standard backset is 2-3/4 inch, which is the usual commercial bored prep, and the latchbolt is stainless with a 1/2 inch throw. It ships with an ANSI strike, 4-7/8 x 1-1/4 inch with a 1-1/4 inch lip to center, so if your frame is already cut for an ANSI strike the replacement is straightforward. Front is 2-1/4 x 1-1/8 inch beveled as standard, with flat fronts available to order, and an optional T-strike can be ordered for the 4700LN if your frame takes one.
4) Can this electrified lever lock go on a fire rated door?
The 4700LN series is UL-cUL fire rated up to 3 hours and carries ANSI/BHMA A156.2, Series 4000, Grade 1 certification. It is also listed as ADA compliant, and the 4700LN is windstorm certified, though windstorm use is always subject to your local code. Confirm the opening's door and frame labels carry the same rating as the hardware.
5) What is the closest cross-brand equivalent to the Accentra 4780LN fail safe electrified cylindrical lever lock?
The Corbin Russwin CL33903 is the nearest match. It is a Grade 1 fail safe electrified cylindrical lever lock offered in a 12VAC/DC version, the same fail safe electrified cylindrical arrangement as the Accentra 4780LN Pacific Beach, which is a Grade 1 cylindrical lever lock offered in 12VDC and 24VDC. The main difference to check is the door: the CL33903 is listed for 1-3/4 inch to 2 inch doors, while the 4700LN chassis adjusts from 1-3/8 inch to 1-3/4 inch. On a 1-3/8 inch door the Accentra is the one that fits; on a 2 inch door the Corbin Russwin is.
6) The door does not need to be electrified - what Grade 1 cylindrical lever should I use instead of the 4780LN?
If there is no access control at the opening, drop to a mechanical Grade 1 cylindrical lever and skip the wiring entirely. The Dexter C1000 classroom function is Grade 1 and keyed for 1-3/8 inch to 1-3/4 inch doors, the Falcon K101 is a Grade 1 heavy duty non-keyed passage lock listed for 1-3/8 inch to 2-1/4 inch doors, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant fire rated passage lock for 1-3/4 inch to 2 inch doors. The Accentra 4780LN is the electrified version and is only worth specifying when the opening is being powered.
7) Can a keypad leverset like the Lockey 2835 or Delaney LP250 replace the Accentra 4780LN?
No - they solve a different problem. 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; both make the access decision at the door itself with a code. The Accentra 4780LN Pacific Beach is an electrified Grade 1 cylindrical lever that takes its release signal from a remote access control system over 12VDC or 24VDC, and it is fail safe with no override, so it unlocks when power is removed. Use a keypad unit only where there is no card reader or panel driving the opening.
8) Do I have to specify handing for the 4780LN lever lock?
No. The 4700LN series is non-handed, so one lock works on a left or right hand door and you are not stocking two versions across a building. Handing on the electrified lever comes down to routing the wire to the correct hinge side, not to the lock itself.
9) Is the Cal-Royal AG05 or Hager 2580 storeroom lever a substitute for the 4780LN?
Only if the opening is dropping its electrified requirement. The Cal-Royal AG05 is a Grade 2 storeroom lever with 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 - both are purely mechanical and both sit a grade below the Accentra 4780LN, which is Grade 1 and electrified. For a storeroom door with no power at the frame either works; for a door on an access control system neither will accept the signal.
10) We are standardizing a corridor on one lever design - what pairs with the 4780LN on the non-electrified doors?
Match the trim family rather than the function. The Accentra 4780LN uses the Pacific Beach lever on a Grade 1 cylindrical chassis, so the rest of the 4700LN series in the same lever design keeps the corridor visually consistent while the electrified unit handles only the controlled openings. If you are willing to mix brands on the unpowered doors, the Corbin Russwin CL3110 Grade 1 passage lock and the Falcon T101 Grade 1 heavy duty passage lever both hold the same grade, though the lever shape will read differently from Pacific Beach.
11) Will a Grade 2 or Grade 3 lever meet the same spec as the Accentra 4780LN?
Not on a Grade 1 specification. The Accentra 4780LN Pacific Beach is certified to ANSI/BHMA A156.2 Series 4000 Grade 1 and UL-cUL fire listed up to 3 hours. Common alternates such as the Falcon B101 and Hager 2510 are Grade 2, and the Cal-Royal AUS00 and Kwikset 200BRNL are Grade 3. Those are appropriate where the drawing calls for a lighter duty lock, but on a Grade 1 institutional or high traffic opening they will not satisfy the submittal.
12) What finishes does the Pacific Beach 4780LN lever 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. For matching existing openings in a building, 626 satin chrome is the common commercial default; BSP and WSP are the choices when the spec calls for painted trim rather than plated.
13) What is the guardbolt on the 4700LN series for?
The guardbolt deadlocks the latchbolt once the door is closed, which stops the latch being shimmed or carded from the outside. It is standard on all locking functions in the 4700LN series. Combined with the 1/2 inch stainless throw, that is what makes this acceptable on a secured access controlled opening rather than just a passage door.
14) Do I need a matching dummy lever on the inactive leaf of a pair with the 4780LN?
Yes, and the dummy is a separate part - the electrified 4780LN chassis is not used on an inactive leaf. For a Grade 1 opening the BEST 9K Series 1DT single dummy trim is a heavy duty Grade 1 non-keyed cylindrical dummy, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent. Confirm the lever shape against the Pacific Beach lever on the active leaf if visual match matters.
