LCN 9140-3077 628 – Frequently Asked Questions

1) What does the LCN 9140-3077 arm assembly actually do, and does it come with the operator?
The 9140-3077 is the arm assembly, the linkage that connects an LCN 9140 Series electromechanical Benchmark operator to the door. It is a replacement or specify-at-order part, not the operator itself. If the operator body is failing, this part won't fix it; if the arm is bent, sprung, or the wrong reach for the mounting, this is the piece you order.
2) Should I order the regular arm or the long arm for my LCN 9140 operator?
Both configurations are offered under the 9140-3077. The regular arm is the standard reach; the long arm is for openings where the operator sits farther from the door face, typically a deeper reveal or a mounting condition that puts extra distance between the header and the door. Measure the reveal on the actual opening before you pick, because the two are not interchangeable once installed.
3) Is the LCN 9140 operator system ADA compliant for a barrier-free entrance?
Yes. The 9140 Series is a low-energy operator that meets ANSI/BHMA A156.19 and ANSI A117.1, and is UL listed. That is the standard governing low-energy power operated doors, which is what facilities use for accessible entrances without the guard rails a full-power automatic door requires. The arm assembly is a component of that listed system.
4) Can I use this LCN 9140 arm on a regular manual door closer?
No. This arm is built for the 9140 Series electromechanical operator and its mounting geometry, not for a standard hydraulic closer. For manual closer arms, the equivalents are brand and series specific: a Deltana DCHA1050 hold open arm serves the DC10 closer, a Deltana DCCA4041 cushion arm serves the DC40, and the Dorma 15323 is a 1-1/2 inch offset bottom arm with cover. Match the arm to the closer series you actually have.
5) Can a Deltana DCHA1050 or DCCA4041 arm be used in place of the LCN 9140-3077 arm assembly?
No. The 9140-3077 is the standard/long arm assembly built for the LCN 9140 Series electromechanical operator, a low-energy powered operator with Push 'N Go activation. The Deltana DCHA1050 is a hold open arm for the DC10 door closer and the DCCA4041 is a cushion arm for the DC40 door closer, so each belongs to its own manual surface closer series. An arm assembly is matched to the closer or operator body it mounts to, so a DC10 or DC40 arm will not drive a 9140 operator.
6) How does Push 'N Go work on the LCN 9140, and do I need a wall push plate?
Push 'N Go activates the operator when someone manually pushes the door open to five degrees and holds it briefly, at which point the operator takes over and completes the swing. That means the opening works without any actuator at all, which is useful in a corridor or vestibule where you can't run wire to a push plate. A knowing act actuator can still be added for users who can't initiate the push.
7) I need automatic operation on a heavy exterior door. Is a 9140 low-energy operator the right approach, or should I look at a floor closer?
Two different jobs. The 9140 is a low-energy power operator, meaning it opens the door for the user, which is what an accessible entrance needs. A floor closer only controls a manually opened door, but it handles far more weight: the Norton Rixson 28 Series is rated to 350 lbs door weight, the 328 Series to 325 lbs, the Norton Rixson 40 Series to 300 lbs, and the 30 Series double acting to 200 lbs, all Grade 1 heavy duty. If the requirement is push-button accessible entry, you want the operator. If it's a heavy monumental door that people will open by hand, a center hung floor closer is the correct device.
8) I manage a building with several LCN 9140 operators. Can I stock one arm assembly for all of them?
Only if the mounting conditions match. The 9140-3077 is offered in a regular arm and a long arm, and which one an opening needs depends on the distance between the operator and the door at that specific location. Doors in the same building often differ. Walk the openings, note which arm is on each, and stock accordingly rather than assuming one part covers the fleet.
9) What is the difference between the LCN 9140-3077 arm assembly and the Dorma 15323 offset bottom arm?
They attach to different kinds of door control. The 9140-3077 is a push-side style standard/long arm assembly for the LCN 9140 low-energy electromechanical operator, supplied in 628 aluminum anodized and ordered as either a regular arm or a long arm. The Dorma 15323 is a 1-1/2 inch offset bottom arm with cover, a standard duty part with no fire rating, used at the bottom of the door where a pivot or floor-mounted control carries the leaf. If the opening uses a header-mounted 9140 operator, the bottom arm is not the part in question.
10) Will a Cal-Royal 900 Series door closer accessories kit cover the arm on an LCN 9140 operator?
No. The Cal-Royal 900-ACC is an accessories kit for the Cal-Royal 900 Series door closers. The LCN 9140-3077 is the standard/long arm assembly for the 9140 Series electromechanical operator and is ordered by arm option, regular arm or long arm, in 628 aluminum anodized. Accessory kits follow the series they are built for, so a 900 Series kit serves 900 Series closers rather than a 9140 operator.
11) What finish does the LCN 9140 arm assembly come in?
Aluminum anodized, finish 628, on both the regular and long arm versions. That is the standard clear aluminum look, so it matches typical aluminum storefront and header hardware. If your existing operator cover is a painted or plated finish, the arm will read as aluminum against it.
12) Is this LCN part rated for commercial use or is it a residential door closer part?
Commercial. The 9140 arm assembly is a component of a commercial low-energy door operator used in offices, healthcare, schools, government buildings, retail, and multi-tenant residential common entrances. It is not a residential closer arm and won't mount to a household closer.
