LCN 3134SE-690 – Frequently Asked Questions

1) Will the LCN 3134SE work on a fire-rated door, and what happens when the fire alarm drops power?
The 3134SE Sentronic is UL listed for metal smoke barrier or labeled fire doors and meets ANSI/BHMA A156.15 and NFPA 101. Wired into the alarm or detection circuit, it holds the door open at a single point and releases the moment current is interrupted. On release it works as a full rack-and-pinion closer, so the door still controls and latches normally with no power at all.
2) Do I have to specify handing when ordering an LCN 3134SE?
Yes, handing is required. The 3134SE is ordered right hand or left hand, so confirm the swing before you place the order. A concealed-in-door closer is machined into the door itself, which is why the wrong hand cannot be flipped on site the way a surface closer sometimes can.
3) Can I power the 3134SE Sentronic from an existing 24V alarm circuit, or does it need 120V?
Either works. The Sentronic closer/holder runs on 24V or 120V, AC or DC, so it ties into a low-voltage fire alarm panel output or a line-voltage circuit without a separate model number.
4) What is the difference between the standard SE track and the long SEL track on the 3134SE?
Track choice is a required selection. The default is the standard arm with SE track; the alternative is the long arm with SEL track. The long arm/SEL track is the option for openings where the standard arm geometry does not reach, such as deeper reveals or frame conditions. Both use the same concealed-in-door closer body.
5) Is the LCN 3134SE ADA compliant and can I use it on a federal job?
It is ADA compliant and BAA qualified, so it clears Buy American Act requirements on government and municipal work as well as accessibility review in schools, healthcare, and office buildings.
6) Can the hold-open force be adjusted after installation on the Sentronic closer?
Hold-open force is field adjustable, so you can tune it to the weight of the door and the traffic on the opening rather than living with a factory setting. The closer uses all-weather fluid, which keeps the closing speed consistent through temperature swings in stairwells, vestibules, and unconditioned corridors.
7) Does the 3134SE have delayed action closing?
No delay function on the 3134SE. If your opening needs extra dwell time for carts, beds, or mobility-impaired users, this is not the closer for it. What it does provide is electrically released hold-open tied to the fire alarm.
8) What fasteners come with the 3134SE and is this a retrofit or new-door install?
It ships with wood and machine screws, covering both hollow metal and wood door and frame conditions. The closer mounts concealed in the door, which means the door has to be prepped for it. On an existing opening that was never machined for a concealed closer, plan on a factory-prepped replacement door or a surface-mounted closer/holder instead.
9) What finishes does the LCN 3134SE come in, and will they match the other closers in my building?
Six powder coat finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Those are standard BHMA finish numbers, so matching an existing fleet is a matter of reading the number off the closers already installed. Note that with concealed-in-door mounting only the arm and track show at the head.
