LCN LCN 4640 -3077 – Frequently Asked Questions

1) How big a door will the LCN 4640 operator handle, interior versus exterior?
The 4640 Series low-energy operator is rated for interior doors up to 4'6" and exterior doors up to 3'6". That gap matters: an exterior opening carries wind load and stack pressure, so the same operator gets a tighter door-width limit than it does on an inside opening. If you're automating a 4-foot exterior entry, the 4640 is not the unit for it.
2) Do I have to order the LCN 4640 handed for a left or right hand door?
No handing to specify. The 4640 operator is non-handed and covers both left- and right-hand door configurations, so one part number works on either swing. That's what makes it practical when you're standardizing a building and don't want two SKUs on the shelf for the same opening type.
3) How does the LCN 4640 automatic operator mount, and which side of the door does it go on?
Top jamb mount on the push side of the opening. That means the unit sits on the frame face above the door, on the side the door swings away from, so you need clear frame face there and no transom obstruction. It ships with a metal cover, the regular arm, and the mounting hardware for that configuration.
4) Is a low-energy operator like the LCN 4640 the right choice, or do I need a full power automatic door?
Low energy is for a door that is primarily manual and needs to open automatically some of the time, activated by a knowing act such as a push plate. The 4640 is built for that duty. A full-power automatic entrance, the kind that opens on a motion sensor at a busy retail vestibule, is a different class of equipment with its own sensor and guard-rail requirements. If the opening is push-button activated accessible entry, low energy is the correct type; if it opens on approach all day, it isn't.
5) Does the LCN 4640 operator meet ADA requirements for an accessible entrance?
It meets accessibility requirements in power mode, which is the mode a low-energy operator uses when it's driving the door open under its own power. That's the condition ADA compliance is claimed under for the 4640, so the opening has to actually be operating in power mode, not left in the off position, for that to hold.
6) Can the LCN 4640 operator release an electric strike before it starts pushing the door?
Yes. The built-in control module handles timing and sequencing and coordinates the electric strike, so the lock releases in the right order relative to the door starting to move. That sequencing is what keeps the operator from driving the door against a still-locked latch, and it's why you don't need a separate sequencer module in a straightforward access control tie-in.
7) Can I adjust how fast and how hard the LCN 4640 pushes the door open after it's installed?
Opening speed and force are both adjustable on the 4640. That adjustment is not optional housekeeping on a low-energy unit, it's how you set the opening to the force and timing an accessible entrance has to meet on site, since the same operator sees very different resistance on a light interior door than on a weatherstripped exterior one.
8) Can the LCN 4640 be switched off or held the door open during business hours?
The operator has easy-access controls for on/off and a continuous hold-open mode. Off leaves the door working as a normal manual closer-operated door; hold-open keeps it standing open for a move-in, a delivery window, or peak traffic, then you switch it back. Useful in multi-tenant common areas where the automatic function is only wanted part of the day.
9) Is the LCN 4640 an electric motor operator or a hydraulic one?
Electrohydraulic. It uses a hydraulic closer body driven electrically, so the door still closes on hydraulic control the way a conventional closer does, and the electric side supplies the powered opening. Practically, that means the opening keeps working as a manual door with normal closing control when the operator is switched off or unpowered.
10) What finish does the LCN 4640-3077 operator come in?
689 aluminum, which is the painted aluminum finish that reads as a neutral silver-grey against most storefront and hollow metal frames. It's the single finish offered on the 4640-3077, so if you're matching existing LCN closers on other openings in the building, expect this one to blend with 689 hardware already on site.
