LCN 4642-REGARM-652 – Frequently Asked Questions

1) Which side of the door does the LCN 4642 mount on?
Push side only. The 4642 is a surface, top jamb mount on the push side of the opening, meaning the operator body sits on the frame face above the door on the side you push to open. If your only available real estate is the pull side, this is the wrong unit for that opening.
2) Does the LCN 4642 meet ADA requirements for a barrier-free entrance?
Yes. The 4642 meets ADA and ANSI A117.1 requirements in power mode and is certified to ANSI/BHMA 156.19, the standard for low energy power operated doors. It also carries UL and cUL listings. For a facility doing an accessibility upgrade, that combination is what an inspector looks for on a low energy operator.
3) Can staff turn the LCN 4642 automatic operation off, and can that switch be hidden from the public?
Both ways are available. The standard build ships with a visible on/off switch plus a hold open switch, which is what you want when staff need to prop the door open during deliveries or events. The CS option gives you a concealed on/off switch with no hold open switch, which is the choice for a lobby, school, or healthcare corridor where you do not want the public defeating the operator. Pick one at order time, because it is a factory configuration, not a field accessory.
4) What power does the LCN 4642 power operator need at the door?
120V. The 4642 runs on standard 120V with an on-board power supply, so the electrician brings line voltage to the header rather than running a separate low voltage supply for the operator itself. Plan the rough-in for a 120V circuit at the top jamb on the push side.
5) Should I use a low energy power operator like the LCN 4642 or a full automatic door operator?
A low energy operator like the 4642 is activated by a person, typically a push plate or wave switch, and opens at a slow controlled rate under ANSI/BHMA 156.19. That is the right choice for an accessible entrance, a restroom, or a corridor door where the goal is barrier-free access without the guard rails, sensors and signage a full power automatic entrance requires. If you need a door that opens automatically for anyone approaching, with motion and presence sensing, you are in full power territory and this is not that unit. The 4642 also still functions as a manual door closer when the power is off, which is what keeps a fire or smoke barrier door closing.
6) What else do I need to order to make an LCN 4642 operator work as a complete automatic opening?
The operator itself is what you get here, and the activation is a separate line item. A working low energy opening needs an actuator on each side of the door, usually a hardwired or wireless push plate at ADA mounting height, plus the wiring between them. If the door has an electrified lock or exit device, that needs to release before the operator drives, so an access control tie-in belongs on the same submittal. Specify the arm length from your frame reveal and choose the standard visible switch or the CS concealed switch at the same time, since both are built in at the factory.
7) Can the LCN 4642 be used on a federal or government project with Buy American requirements?
Yes. The 4642 is BAA qualified, which is the box a government, municipal, or federally funded institutional job needs checked before the submittal is approved.
8) Do I have to specify a closer size when ordering the LCN 4642?
No. The 4642 uses non-sized cylinders, so one unit covers closer sizes 2 through 5 rather than making you pick a spring size per opening. That is what lets the same operator serve both a light interior door and a heavier exterior leaf within its size range, and it is useful when you are standardizing across a building.
9) What is the difference between the regular arm and long arm option on the LCN 4642?
Arm choice is driven by your frame reveal, the distance from the face of the door to the face of the jamb where the operator mounts. The 4642 is ordered with either a regular arm or a long arm, and the long arm is what covers deeper reveals where a regular arm cannot reach the door. Both are offered in all seven plated finishes, so the arm decision does not restrict your finish.
10) How far will the LCN 4642 open the door, and will it hold it open?
180 degrees is the rated opening, and hold open is included on the standard configuration with the visible switch. Full 180 degree swing matters for a healthcare corridor or a loading route where a gurney or cart needs the leaf flat against the wall. If you order the CS concealed switch version you get the concealed on/off but no hold open switch.
11) Will an LCN 4642 operator hold its adjustment on an exterior door through winter?
It uses all-weather hydraulic fluid, which is the reason an electrohydraulic operator can sit on an exterior opening without the closing speed swinging wildly between a cold morning and a hot afternoon. The digital control box also carries a factory default memory, so if someone has fiddled with the settings you can return it to a known baseline instead of re-tuning by trial and error.
12) What finishes does the LCN 4642 come in to match existing door hardware?
Seven plated finishes are offered on the cover, arm and fasteners: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. If the building standard is 626 satin chrome on the lever trim, 652 is the plated match to specify here. Every finish is available with either arm and either switch configuration.
13) Is the LCN 4642 built to survive a high traffic entrance?
The 4642 uses LCN's "No Destruct" drive, which is there specifically for the abuse case: someone shoving the door open by hand while the operator is driving it. The drive absorbs that rather than stripping, which is the usual failure mode on a school or hospital entrance. Body construction is iron, and it is rated commercial rather than residential.
