LCN 4311HSA-689 – Frequently Asked Questions

1) How does the LCN 4311HSA Sentronic hold a door open without a separate wall magnet or detector?
The hold-open is built into the closer itself. A scanner in the 4311HSA body senses someone passing through and holds the door open at 80 degrees or more, then releases it after an adjustable timer of up to 30 seconds. There is no separate floor or wall-mounted magnetic holder to install and wire, so the only device on the opening is the closer/holder on the pull side. On a fire or life safety signal the unit is intended to work with the building's fire and life safety system, which is what makes it suitable for openings that must close on alarm.
2) What power does the LCN 4311HSA closer/holder need, and can it run off standard door hardware power?
It runs on 24VAC or 24VDC. That is the same power most access control and fire alarm interface power supplies already provide in a commercial building, so the 4311HSA usually ties into an existing 24V supply rather than needing a dedicated transformer. Plan on running low voltage to the head of the opening on the pull side, where the closer mounts.
3) Can the LCN 4311HSA be mounted on the push side of the door or on the frame face?
No. The 4311HSA is a pull side, hinge-side surface mount closer with a track arm. If your opening only allows push side mounting, because the door swings out into a corridor or the pull side has no usable frame face, this is the wrong unit and you need a closer configured for top jamb or parallel arm mounting instead. Confirm which side of the door you are standing on when the door pulls toward you, that is the pull side.
4) Do I have to specify handing when ordering the LCN 4311HSA Sentronic?
Yes, handing is required. The 4311HSA is ordered right hand or left hand, so you need to determine the door's hand before placing the order. Stand on the outside of the door, the side it swings away from, and note which side the hinges are on: hinges on the right is right hand, hinges on the left is left hand. Ordering the wrong hand on a track closer means the track and arm sit backward on the opening.
5) Will the LCN 4311HSA work on a double egress pair of doors?
Yes, but you have to order it with the Double Egress arm rather than the standard track arm. Double egress pairs swing in opposite directions in the same frame, and the geometry at the hinge side differs from a normal opening, so the DE arm is the option to select. On a standard single swing door the standard track arm is the one you want. Pick the arm at the same time you pick the hand, both are order-time choices on this closer.
6) Does the LCN 4311HSA meet ADA opening force and the life safety codes an inspector will check?
ADA compliant, and it meets ANSI/BHMA A156.15 and NFPA 101 Life Safety Code. That combination is what a facility needs on a corridor or smoke barrier door that must be held open for traffic and release on alarm. The adjustable spring power range is what lets you tune opening force down for an accessible route while keeping enough closing force to latch the door.
7) Is the LCN 4311HSA Buy American Act compliant for a federal or municipal project?
Yes, the 4311HSA is BAA qualified, which is what a government or municipal spec typically calls for on door hardware. Pair that with its ANSI/BHMA A156.15 and NFPA 101 compliance and it covers the usual submittal requirements on a public building corridor door.
8) What finishes does the LCN 4311HSA Sentronic come in, and will it 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 the standard LCN closer finish numbers, so if the closers already on your other openings are marked 689 or 695, order the same number here and the covers will read as a set. Powder coat is the finish type on all six.
9) Can the hold-open feature on the LCN 4311HSA be shut off if a tenant does not want doors standing open?
Yes. There is a built-in On/Off switch for the hold-open function, and the hold-open period itself is adjustable up to 30 seconds. Switch it off and the unit behaves as a heavy duty door closer; switch it on and the scanner resumes holding the door at 80 degrees for the set delay. That is useful when the same opening is high traffic during the day and needs to stay closed after hours.
10) Should I use a self-contained closer/holder like the 4311HSA or a plain closer with a separate magnetic hold-open?
The tradeoff is device count versus flexibility. The 4311HSA puts the closer, the hold-open and the pedestrian scanner in one cast iron unit on the pull side, wired to 24VAC/DC, so there is one thing to mount, one thing to wire, and no wall or floor magnet in the traffic path. A plain closer with a separate wall magnet lets you place the hold-open point wherever the wall allows and hold at angles the track does not reach, but it is two devices, two mounting points, and a magnet that gets knocked out of alignment. For a corridor or smoke barrier door where the wall behind the door is not usable or gets damaged, the self-contained unit is the cleaner install.
11) What fasteners come with the LCN 4311HSA and will they work on a hollow metal frame or a wood door?
Both wood and machine screws are supplied, so the pack covers a wood door and a hollow metal or aluminum application where you are threading into tapped holes. On hollow metal you will typically want the frame and door reinforced or through-bolted for a cast iron closer of this weight, since the arm loads the mounting points every cycle.
12) Will the LCN 4311HSA hold up in an unheated warehouse or a vestibule that gets cold?
It uses all-weather fluid, which is what keeps the closing speed from swinging with temperature, so a loading dock corridor, an unconditioned warehouse, or a cold vestibule will not need the valves reset every season. Note the unit is specified for interior doors, so use it on an interior opening in those spaces rather than the exterior entrance itself.
