LCN 4311HSA-652 – Frequently Asked Questions

1) How does the hold-open work on the LCN 4311HSA Sentronic closer/holder?
The 4311HSA uses a built-in HSA scanner in the track. Push the door open to 80 degrees or more and it holds electrically on 24VAC/DC power. Drop the power (fire alarm signal, or any loss of power) and the door releases and closes. There is also an adjustable timer that will let the door go after a set hold-open period of up to 30 seconds, which is useful where people prop doors during deliveries or class changes.
2) Will the 4311HSA work on an exterior entrance door?
No. The 4311HSA Sentronic is specified for interior doors, so use it on corridor, cross-corridor, stair and smoke barrier openings inside the building. For an exterior opening you want a closer specified for exterior use. The all-weather fluid in this unit is about keeping the closing speed consistent through temperature swings in unconditioned interior spaces, not about mounting it outdoors.
3) Which side of the door does the 4311HSA mount on?
Pull side, hinge mounted, surface applied to the door face with the track on the frame. If your opening only gives you the push side (door swings toward you into a corridor, or the pull side is blocked by a transom or wall return), this mounting will not work and you need a push-side application instead. Verify which way the door swings before you order handing.
4) Do I have to specify handing when ordering the 4311HSA?
Yes, handing is a required selection: right hand or left hand. Because this is a track closer/holder with a scanner in the track, it is built for one hand and is not field reversible the way a plain regular-arm closer often is. Stand outside the opening, see which side the hinges are on, and order to match.
5) Can the LCN 4311HSA be used on a double egress pair?
Yes, but you have to order it with the double egress arm rather than the standard track arm. Double egress frames have the two leaves swinging opposite directions with a flush frame profile, and the standard track arm geometry will not pick that up. The arm is a required choice at order time, so pick DE for double egress and the standard track arm for a conventional single-swing opening.
6) Does the 4311HSA meet code for holding a fire or smoke door open?
It is built for that duty and meets ANSI/BHMA A156.15 and the NFPA 101 Life Safety Code, which is the pairing your AHJ looks for on a hold-open device at a smoke or fire barrier. The electrical hold releases on loss of power, so it ties into an existing fire alarm system without a separate magnetic holder. It is also BAA qualified, which matters on federally funded work.
7) What power do I need to run to the door for a 4311HSA?
24VAC or 24VDC. Run the power through your fire alarm control panel relay or an alarm-interfaced power supply so that the hold-open drops when the panel signals. Power has to reach the closer on the door, so plan for an electric hinge or a power transfer at the hinge edge as part of the opening.
8) What finishes does the LCN 4311HSA Sentronic come in?
Six plated finishes on the metal cover, arm and fasteners: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. If you are matching existing hardware in a building, 652 satin chrome is the common commercial pairing with satin stainless trim, and 646 satin nickel reads warmer against brushed-nickel levers.
9) Why use a Sentronic closer/holder instead of a separate closer plus a wall magnet?
A magnetic holder is two devices, two mounting points and a floor or wall obstruction, and the door still swings past the magnet if someone shoves it. The 4311HSA puts the closing and the electric hold in one surface unit on the door, with the hold happening in the track at 80 degrees and no wall hardware to hit. Where you want an unpowered door that simply stays open mechanically, a plain closer with a hold-open arm is the cheaper answer, but it will not release on a fire alarm.
10) What fasteners come with the LCN 4311HSA and will it mount to a hollow metal frame?
Wood and machine screws are supplied, so you are covered for a wood door and frame or for hollow metal where you drill and tap for the machine screws. On a hollow metal door with no reinforcement behind the closer location you will need sex bolts or thru-bolts, which are ordered separately.
11) Is the 4311HSA tough enough for a high traffic corridor?
The closer body is cast iron with full-complement bearings, which is the heavy duty construction you want in school corridors, hospital wings and warehouse openings. The hold-open at 80 degrees is itself a durability feature: the door sits parked instead of being repeatedly slammed against a stop, so arm and hinge wear drops in traffic.
