LCN 9540-3454 RH – Frequently Asked Questions

1) Does the LCN 9540-3454 motor gearbox come handed, and how do I know which one to order?
Handing matters here. The 9540-3454 standard force motor gearbox is built left hand or right hand, and those are the only two choices. Order it to match the swing of the operator already on the opening, not to the door you wish you had. Pull the handing off the existing 9540 operator before you order the replacement gearbox.
2) What does the LCN 9540-3454 actually fit? Will it work on any LCN swing door operator?
The 3454 standard force motor gearbox is a service part for the LCN 9540 Series electromechanical Senior Swing operator. It is not a universal drive unit and it is not a complete operator. If the header on the opening is a 9540, this is the gearbox that goes inside it. If it is another LCN operator series, this is the wrong part.
3) What door width does the LCN 9540 operator handle, and will the standard force gearbox drive a 48 inch door?
Single doors from 33 inches minimum to 48 inches maximum width. The standard force motor gearbox is matched to that range, so a 48 inch leaf is at the top of what it drives, not beyond it. Anything narrower than 33 inches is outside the operator's rating regardless of which gearbox is in it.
4) Our building inspector asks about the automatic operator on our accessible entrance. What standards does the LCN 9540 carry?
ANSI A156.19 Grade 1, with UL325/228 and UL1998 listings. That is the low energy power operated door standard the accessibility inspection is looking for. The 3454 gearbox is a component of that certified operator, so replacing it with the correct standard force unit keeps the assembly as originally listed. The 9540 also meets Buy American Act requirements, which matters on federal and state funded work.
5) Can a Norton Rixson floor closer be used instead of the LCN 9540-3454 motor gearbox?
No - they do different work. The 9540-3454 is the standard force motor gearbox that drives an LCN 9540 Series electromechanical Senior Swing operator, powering the door open for automatic wheelchair access while still allowing manual push operation. The Norton Rixson 28 Series is a center hung single acting heavy-duty floor closer rated to 350 lbs door weight, and the Norton Rixson 30 Series is a center hung double acting heavy duty floor closer rated to 200 lbs door weight. Both are mechanical closers set into the floor at the bottom pivot: they control the door on its return, they do not open it, and neither has a motor to replace. If the opening needs powered operation, the gearbox stays inside the 9540 operator; if the requirement is only controlled closing on a heavy center hung door, a floor closer is the correct family of product.
6) Is the LCN 9540 an automatic door only, or can people still push it open by hand?
Both. The 9540 Senior Swing is a two in one: powered opening on actuation for wheelchair access, and normal manual push pull operation the rest of the time. That is why it goes on entrances that carry general pedestrian traffic and an accessible route at the same time. The motor gearbox is the drive side of that arrangement.
7) What mounting configuration does the LCN 9540 use on the door?
Surface mount, push side, with a regular arm assembly, working on butt hinge or offset pivot hung doors. If your opening is center hung or the operator has to pull the door from the opposite face, the 9540 as configured here is not the arrangement you have.
8) My door has a floor closer, not an overhead operator. Is the 9540 gearbox any use to me?
No. The 9540-3454 is the motor drive inside a powered overhead swing operator. A center hung floor closer is a different animal entirely, and none of its parts interchange. For center hung floor closer work ZenSupply carries the Norton Rixson 28 Series single acting heavy duty unit rated to 350 lbs door weight, the 328 Series at 325 lbs, and the 30 Series double acting at 200 lbs. Match the replacement to the acting and the leaf weight you have.
9) The door is closing too fast and we were told to replace the gearbox. Is that the right fix?
Probably not, if the complaint is only closing speed. The 3454 is the powered drive unit for a 9540 operator, so it is the part you buy when the motor or gear train has failed and the door will not power open. Speed and hold open behaviour on a manual closer is arm and valve territory. On the manual closer side ZenSupply stocks arm parts such as the Deltana DCHA1050 hold open arm for the DC10 and the DCCA4041 cushion arm for the DC40, plus the Dorma 15323 1-1/2 inch offset bottom arm with cover.
10) Are we buying a whole LCN 9540 operator here, or just the motor?
Just the motor gearbox. The 9540-3454 is a replacement component that goes into an existing 9540 Senior Swing header, so the header, arm, control board and cover stay on the wall. Order it by model and by handing, left or right.
11) Is a door closer arm or accessory kit an equivalent replacement part for the LCN 9540-3454?
No. The 9540-3454 is the powered drive component - the standard force motor gearbox inside a 9540 Series electromechanical swing door operator, supplied left hand or right hand to match the door. The comparable service parts are for manual closers and are not interchangeable with it: the Deltana DCCA4041 is a cushion arm for the DC40 door closer, the Deltana DCHA1050 is a hold open arm for the DC10 door closer, the Cal-Royal 900 Series accessories kit serves 900 Series commercial door closers, and the Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, standard duty and not fire rated. Those are linkage and trim pieces that transmit the force of a spring closer. Ordering one of them against a 9540 operator gets a part that has no mounting point in the operator housing, and handing must still be specified on the gearbox itself.
12) Can the LCN 9540 operator go on an exterior entrance, or is it interior only?
Exterior is within scope. The 9540 is built for all weather fluid compatibility and the system is tested to 100 hour salt spray, which is what you want on a coastal or road salt entrance. It is a commercial duty operator, not a residential one.
13) We standardize automatic entrances across a hospital campus. Does the 9540 gearbox suit that kind of program?
It does, and that is the usual reason to stock it. The 9540 Senior Swing is specified on healthcare accessibility openings, education, government buildings, retail entrances and multi tenant residential common areas. Stocking the standard force gearbox in both hands means a failed operator on any 33 to 48 inch leaf on campus can be back in service without pulling the whole header.
