LCN 4040SE-652 – Frequently Asked Questions

1) Will the LCN 4040SE hold a fire door open and release it when the alarm goes off?
That's exactly what the 4040SE Sentronic does. It's a surface closer/holder with an electromagnetic hold-open that keeps the door open under power and drops it closed the moment current is interrupted, so the door closes on alarm or power loss. It's UL listed for metal smoke barrier and labeled fire doors and meets ANSI/BHMA A156.15 and NFPA 101. Holding force is field adjustable, so you can tune it to the weight of the door you're on.
2) What voltage does the LCN 4040SE Sentronic closer/holder run on?
24V or 120V AC/DC, both standard, so it ties into either a low-voltage fire alarm circuit or line voltage without a different part number. Over-voltage protection is built in. Since the hold-open is electromagnetic, whatever circuit you put it on has to be the one your alarm panel drops on activation, otherwise the door never releases.
3) How wide a door will the 4040SE Sentronic handle?
Up to 4 feet 0 inches wide. The body carries a 1-1/2 inch diameter piston in a cast iron housing, and spring power is available in closer sizes 1 through 4, so you size it to the leaf you're hanging it on. Wider than 4'0", or an exterior opening taking wind load, and you're past what this closer/holder is specified for.
4) Do I have to order the 4040SE handed, and which hand do I need?
The closer body itself is non-handed and works on right- or left-swinging doors with no field modification. But the arm and cover are handed choices you make on the order: the arm is either a standard track arm or a double egress right hand or left hand, and the metal cover comes right hand or left hand. So the assembly you receive is handed even though the closer is not. Determine hand from the swing before you place the order.
5) What do I have to specify when ordering a 4040SE besides the finish?
Three choices are required alongside the finish. Arm: standard track arm, or a double egress arm in right or left hand. Track: standard or long. And cover: metal, right hand or left hand. The long track is the one to pick where the hold-open point needs to sit further out on the door. Get the arm and cover hand wrong and the parts won't assemble to the swing you have.
6) I just need a heavy duty closer, not a fire alarm hold-open. What else could I buy?
If the door doesn't need to release on alarm, you're paying for electronics you won't use. Straight heavy-duty surface closers we carry include the Sargent 281 Powerglide, also a cast iron body and Grade 1, the BEST EHD9000 Series extra heavy-duty with adjustable sizes 1-6, and the Falcon SC71A Series Grade 1 heavy duty. All three are mechanical only, no wiring, no panel tie-in. Keep the 4040SE for the rated barrier doors and spec a mechanical closer everywhere else.
7) Can a mechanical hold-open arm closer be used in place of the 4040SE on a fire door?
No. A mechanical hold-open arm holds the door open by friction or a detent in the arm and has no connection to the fire alarm system. The Accentra 51 Series carries a tri-packed hold open arm, and the Orca Hardware BHDC1958HO/PA is also a tri-packed hold open arm closer; both hold the door open until someone physically pushes it free. The LCN 4040SE holds electromagnetically and releases automatically the moment current is interrupted, which is what allows it to be UL listed for metal smoke barrier and labeled fire doors and to meet ANSI/BHMA A156.15 and NFPA 101. On a labeled opening the electromagnetic release is the requirement, so a mechanical hold-open arm is not a substitute.
8) What is the closest heavy-duty cast iron alternative to the LCN 4040SE for a fire-rated opening?
The LCN 4040SE is a cast iron bodied closer/holder with electromagnetic hold-open that releases when current is interrupted, running on 24V or 120V AC/DC. Among cast iron heavy-duty surface closers, the Sargent 281 Powerglide is also a cast iron body, heavy duty, Grade 1 unit. The difference that matters: the 281 is a mechanical closer with no electrical hold-open, so it closes the door on every cycle rather than holding it open until the fire alarm system drops power. If the opening needs to stand open during normal use and self-close on alarm, the electrified 4040SE does that and the 281 does not.
9) If the door does not need to be held open, what is a simpler closer than the LCN 4040SE?
The 4040SE carries the electromagnetic holder, the track, and the 24V or 120V power feed, all of which exist to hold the door open and drop it on alarm. Where the door just needs to close on every cycle, a non-hold-open surface closer removes the wiring entirely. The BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1 through 6, and the Sargent 1431 Powerglide is a heavy-duty Grade 1 surface closer with adjustable spring power. Both are self-closing only and need no power at the opening; neither will hold the door open under alarm control.
10) Is a slide track closer like the Corbin Russwin DC5230 the same thing as the LCN 4040SE?
They share the track arrangement but not the function. The Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard, pull side mounting, and it is a mechanical closer. The LCN 4040SE runs its arm in a track as well, but the track carries an electromagnetic holder fed by 24V or 120V AC/DC that releases the door when current drops. A slide track closer gives the low-profile arm look; it does not give alarm-released hold-open, so on a labeled fire or smoke barrier door the two are not interchangeable.
11) Can the LCN 4040SE be mounted on the push side of the door?
Both sides work. Hinge (pull side) mounting and stop face (push side) mounting are both covered, so you pick based on which face is free of other hardware and where you want the track to land. Mounting is surface, with wood and machine screws supplied, meaning no mortising and no through-bolt prep in the door.
12) What finishes does the LCN 4040SE Sentronic come in?
Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. These are plated rather than painted, so if you're matching existing LCN closers across a building, match the BHMA number and not just the colour name, 651 and 652 read very differently side by side.
13) Is the 4040SE closer ADA compliant for a public corridor door?
Yes, the 4040SE carries ADA compliance and is also BAA qualified, which matters if you're buying for a federal or federally funded project with domestic sourcing requirements. It's a commercial-rated unit with spring sizes 1 through 4, so the opening force at the door can be set down to what an accessible opening needs.
14) Is the LCN 4040SE rated for an exterior entrance door?
It's specified for interior doors. The all-weather hydraulic fluid keeps the closing speed consistent through temperature swings, which is why it holds up in unconditioned corridors and stairwells, but the application is interior, and the intended use is fire and smoke barrier openings. For an exterior entrance you want a closer specified for that duty, such as the Norton Rixson 1600BC Series aluminum storefront closer or the Falcon SC71A heavy duty.
15) Can the 4040SE be used on a double egress pair of doors?
Yes, that's what the DE arm options are for. Ordering the arm as DE - RH or DE - LH gives you the double egress configuration, and on a double egress pair you order one closer per leaf with the arm handed to that leaf's swing. Track selection, standard or long, should be the same on both leaves so the hold-open points match.
16) What is the difference between the LCN 4040SE and a standard 4040 closer?
Same 4040 family and the same cast iron heavy-duty body, but the SE is the Sentronic version: it adds the electromagnetic hold-open and the track, and it needs a 24V or 120V AC/DC supply. A standard hydraulic 4040 just closes the door and takes no power. The SE is what you spec when the code official wants the hold-open to release on alarm; there's no benefit to it on a door that isn't a rated barrier or isn't meant to stand open.
17) What should be used instead of the LCN 4040SE on an opening that cannot take a track?
The 4040SE is a track closer: the arm rides a track and the ordering choices include a standard or long track. On an opening with no room for a track head or where the frame face rules it out, a conventional arm closer is the way to go. The Corbin Russwin DC6200 Series is a Grade 1 surface closer with a double lever regular arm mounted pull side, and the Corbin Russwin DC3200 is a Grade 1 surface closer with a regular arm. Both swing a projecting arm rather than running in a track, and neither carries an electromagnetic holder.
18) For a light interior door where the 4040SE is more closer than the opening needs, what else works?
The 4040SE uses a 1-1/2 inch diameter piston in a cast iron body for doors up to 4 feet wide, sized 1 through 4. On a light interior door with no fire or hold-open requirement, a lighter aluminum-body closer fits better. The Falcon SC91A Series is a light duty cast aluminum surface closer at Grade 3, and the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes. Both are mechanical, non-electrified units with no track holder.
19) Does the Dorma 8916-JT jamb track closer do what the LCN 4040SE does?
The Dorma 8916-JT is a Grade 1 heavy-duty surface closer with a jamb track, frame face mounting, pull side, adjustable size 1 through 6, and a flat non-hold-open arm. It rides a track like the 4040SE and covers a wider spring range, but its arm is non-hold-open and it is not electrified. The 4040SE is non-handed for right- and left-swinging doors and holds the door open electromagnetically with field-adjustable holding force until power is interrupted. Choose the 8916-JT when the opening only needs to close; choose the 4040SE when the door must stand open and drop on alarm.
20) Does any comparable closer need to be ordered handed the way the LCN 4040SE cover and arm do?
The 4040SE body itself is non-handed and takes both right- and left-swinging doors without field modification, but the track arm and the metal cover are ordered right hand or left hand, so handing has to be confirmed before the order goes in. Most mechanical surface closers avoid that question entirely by shipping tri-packed for regular, parallel, or top jamb mounting: the Dexter DCH4000 Series and the Dexter DCL2000 Series are Grade 1 tri-mount closers, and the Norton Rixson 8501A is a Grade 1 tri-mount closer with adjustable size 1 through 6 spring. Those ship one way and are set at the opening.
21) What closer covers a heavier or wider door than the LCN 4040SE handles?
The 4040SE is built for doors up to 4 feet wide in sizes 1 through 4. Where the leaf is wider or heavier than that band covers, a closer with spring power up through size 6 is the move. The BEST HD8000 Series is a heavy-duty Grade 1 surface closer, the Imperial USA TC4300 Series is a heavy-duty Grade 1 closer in sizes 1 through 6, and the Accentra 2701 Series is an architectural closer with adjustable spring sizes 1 through 6 on a tri-pack non-hold-open arm. All three are mechanical closers without electromagnetic hold-open, so a fire door that must stand open still needs the electrified unit.
22) Is a delayed action closer an alternative to the LCN 4040SE for holding a door open?
Not for the same purpose. A delayed action closer such as the Orca Hardware BHDC1958DA/PA or the Orca Hardware BHDC2011DA/PA slows the door through the first part of its swing so someone has longer to pass through, then closes it on its own; both are tri-packed non-hold-open arm closers. The door never actually stops and stays open. The LCN 4040SE holds the door fully open on an electromagnet with field-adjustable holding force and releases it when current is interrupted. Delayed action helps traffic flow; only the electrified holder keeps a fire door standing open under alarm control.
23) Is the Stanley A45-501HL long hold open arm closer a substitute for the LCN 4040SE?
No. The Stanley Security A45-501HL is a long hold open arm standard, top jamb closer, which means the door is held by the arm mechanically and stays there until it is pushed closed. The LCN 4040SE is a surface mounted closer/holder with an electromagnetic hold-open on a track, powered at 24V or 120V AC/DC, that drops the door when current is interrupted. The two answer the same plain-language request to keep a door open, but only the 4040SE ties that hold to the building's power and alarm.
24) Can I adjust how hard the 4040SE holds the door open once it's installed?
Holding force is field adjustable on the Sentronic, so a light interior leaf and a heavy 4'0" fire door can both be set to hold without the door creeping or being too stiff to pull free by hand. Spring power itself is by closer size, 1 through 4, which is chosen at order rather than dialled in, so pick the size for the door width first and use the holding-force adjustment for fine tuning.
25) Does the 4040SE come with the mounting hardware, or do I need to order screws separately?
Wood and machine screws are included, which covers both a wood door or frame and a hollow metal one. Because it surface mounts, there's no mortise prep, but the required arm, track and cover are order-time selections rather than a single default assembly, so confirm those three lines are on the purchase order or the closer arrives without a way to mount the track.
26) For standardizing across a facility on plated finishes, how does the LCN 4040SE line up with mechanical closers?
The 4040SE comes in plated finishes across 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, and 651 bright chrome and 652 satin chrome, so the electrified fire door openings can match the rest of a hardware schedule. On the non-rated openings in the same facility, Grade 1 mechanical closers carry the ordinary traffic: the Sargent 1131 and Sargent 1331 are both medium-duty Grade 1 surface closers, and the Norton Rixson 1601P is a medium-duty Grade 1 tri-mount closer with 180 degree swing. Specifying the 4040SE only where the alarm-released hold-open is required keeps the count of powered openings down.
