LCN 3134SE-652 – Frequently Asked Questions

1) Does the 3134SE release the door automatically when the fire alarm goes off?
Yes. It holds the door open electrically, and when current is interrupted the hold-open releases and the closer shuts the door. That is how it ties into a fire alarm or smoke detection system: the panel drops power, the door closes. It is UL listed for smoke barrier or labeled fire doors, with cUL listing for self-closing doors without hold-open.
2) What voltage do I need to run to an LCN 3134SE Sentronic closer?
It runs on 24V or 120V, AC or DC, as standard, so you can tie it to a low-voltage fire alarm circuit or a line-voltage supply without ordering a different model. Plan the rough-in wiring to the head of the frame before the door hangs, since both the closer body and the track are concealed.
3) Is the 3134SE mounted on the door face or hidden inside the door?
Hidden. The closer body is concealed in the door itself and the track is concealed in the frame head, so nothing shows on the face of the door. That means the door has to be prepped and morticed for the closer body, and the frame has to be prepped for the track. It is not a retrofit you drop onto an unprepped door.
4) Do I have to specify handing when ordering the LCN 3134SE?
Yes, handing is required. You pick Right Hand (RH) or Left Hand (LH) at the time of order. Determine it by standing on the outside of the door, the side you push from into the room: if the hinges are on your right it is right hand. A concealed-in-door closer cannot be flipped on site the way a surface closer can, so get this right before it ships.
5) Is the LCN 3134SE Sentronic ADA compliant and does it meet code for a fire barrier door?
It is ADA compliant, and it meets ANSI/BHMA A156.15 and the NFPA 101 Life Safety Code for interior doors up to 4'0". It is UL listed for smoke barrier or labeled fire doors. For federal and government work it is also Buy American Act qualified.
6) What is the difference between the standard arm/SE track and the long arm/SEL track on the 3134SE?
Two arm and track combinations are offered: the Standard Arm with SE track (STDTRK), which ships as the default, and the Long Arm with SEL track (LONG). The long arm/track version is the one to select where the door needs the extra arm reach for the frame condition; otherwise the standard arm covers it. This is a required selection on the order, so you choose one either way.
7) Can I adjust the closing force on the 3134SE, or is it fixed?
The unit is a size 4 closer with a 1-1/8 inch diameter piston, and the hold-open force is field adjustable so you can tune it to the weight of the door. Note that there is no delayed action feature on this model, so if the opening needs a delay for slow-moving occupants you are looking at a different closer.
8) What finishes does the LCN 3134SE come in, and will it match my other door hardware?
Seven plated finishes are available: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. Since these are standard BHMA finish numbers, matching across a building is a matter of pulling the number off your existing hardware. Bear in mind only the arm and track are visible on a concealed installation, so the finish decision is a small amount of exposed metal at the frame head.
9) Are mounting screws included with the 3134SE, or do I need to source them?
Wood and machine screws come with the closer, so it covers both a wood door and a hollow metal application. What is not in the box is the electrical supply side, so budget for the power feed and the tie-in to the fire alarm circuit as separate line items on the job.
10) Is a cast iron closer body worth it over an aluminum one for a high-traffic corridor?
The 3134SE body is iron, which is what you want on doors that cycle hard all day in schools, hospitals, and office corridors. Combined with the size 4 spring rating and the concealed mounting, which keeps the mechanism out of reach of abuse and tampering, it suits corridor and stairwell fire doors in institutional buildings.
