Norton Rixson 5740K3 689 – Frequently Asked Questions

1) Does the Norton Rixson 5740K3 door operator mount on the push side or the pull side?
Either side. The 5740K3 kit ships with both a push arm and a pull arm, and the operator itself is surface applied to either face of the door, so the mounting side is decided at the opening instead of on the order form. That matters when a transom, a header condition, or existing hardware blocks one face. You install the arm that matches the side you mount on and keep the other.
2) What happens to the door if the power goes out on a 5740K3 operator?
It reverts to being a closer. The 5740 is built on a hydraulic closer body, so with power off the door still closes under spring pressure at whatever spring size it is set to, 1 through 6. What you lose is the powered opening cycle: people push the door open by hand and it closes and latches behind them. There is also an end user on/off switch, so a facility can deliberately take the automatic function out of service overnight and leave the door working as a manual surface closer.
3) Is the 5740K3 a full automatic door operator, and will I need guide rails and sensors?
Low energy, not full power. The 5740K3 is certified to ANSI/BHMA A156.19, the standard covering low energy power operated doors: they open at a controlled slow rate and are triggered by a knowing act, which is exactly why the kit comes with push buttons and transmitters instead of motion sensors. Full powered automatic entrances are governed by A156.10 and require sensors and guide rails around the swing. A156.19 openings do not, so this is the operator type used for an accessible side entry, a restroom, or a code upgrade where rebuilding the vestibule is off the table.
4) What comes in the Norton Rixson 5740K3 kit, and do I need to buy anything else to open the door?
The 5740K3 ships as a complete package: the 5740 operator with a full cover, both the push arm and the pull arm, a power cord, a radio receiver, two push button switches, and two transmitters. That gives you the operator, an actuator for each side of the opening, and wireless activation, so a straight accessible door opener needs nothing added. Locking is the piece that sits outside the kit. If the opening uses an electric strike, a maglock, or a card reader, those are sourced separately and wired to the operator.
5) Can I tie an electric strike into the 5740K3 operator, and how much accessory power does it have?
The 5740 runs on 24VDC and provides 1.1A of accessory output. Total the draw of the receiver and any locking device you intend to hang off it against that 1.1A before you commit the design. Sequencing is handled by the adjustable open delay: the operator waits before it drives the door, so an electric lock has time to release instead of the motor fighting a latch that is still thrown.
6) Can a Norton Rixson 5740K3 replace the surface closer already on my door, or does the opening have to be rebuilt?
It takes the place of the closer. The 5740 is surface applied to the door leaf with an arm to the frame, the same footprint the existing surface closer occupies, so an accessibility upgrade on an existing opening comes down to swapping the closer and getting power to the head. Door, frame, and hinges stay. Two things to confirm before you order: the leaf falls inside the 28 to 48 inch width range, and the door and hinges are sound enough to be driven by a motor rather than shoved by hand.
7) Are the push buttons that come with the 5740K3 wireless, or do they have to be wired back to the operator?
Two different things ship in the same box. The two push button stations are hardwired, run in appropriate gauge wire from the switch location back to the operator. The two transmitters are wireless and pair to the receiver that also comes in the kit, which is how you get an actuator on a wall you cannot fish conduit to, or a fob for staff. Most installs use both: hardwired plates at each side of the opening, transmitters where running wire is not practical.
8) Is the Norton Rixson 5740K3 rated for a busy main building entrance?
Its rating is moderate traffic, with heavy duty commercial construction behind it. That covers an accessible side entry, a corridor door, a restroom, or a tenant suite door well. If you are automating a primary lobby entrance that cycles continuously through the day, the category built for that duty is a full power automatic entrance under A156.10, not a low energy operator. Being honest about the cycle count up front is cheaper than replacing an under specified operator in eighteen months.
9) Does the Norton Rixson 5740K3 meet ADA requirements for an accessible entrance in a government or healthcare facility?
The 5740K3 is ADA compliant and certified to ANSI/BHMA A156.19, and it carries both UL and cUL listing. For a facility standardizing accessible openings, that combination is what the specification and the inspector are looking for: the operator standard, the accessibility requirement, and the electrical listing on both sides of the border. The same kit repeats across openings from 28 to 48 inches wide, which keeps one part number and one set of adjustment procedures across a building.
10) What keeps the 5740K3 from swinging the door into somebody standing behind it?
Obstruction detection is the primary protection: the operator stops the motor during the opening cycle when the door meets resistance, with an overload safety shut off behind it. Backcheck is the mechanical half of the same problem, catching the door before it drives into a wall or a stop near the end of the opening swing. The end user on/off switch lets staff pull the powered function entirely if an opening is being worked on or a crowd is moving through.
11) The door is slamming and not latching after we installed a 5740K3. What adjusts what?
Three independent valves plus the spring. Sweep sets the main closing speed across most of the arc, latch controls the last few inches into the strike, and backcheck slows the door near the end of the opening swing. Closing force is separate and comes from the spring, adjustable through sizes 1 to 6. A door that closes fast but stalls short of the latch is usually a sweep and latch balance rather than spring size. Set them once the operator is mounted and powered, then re-check after the door has run a few dozen cycles and the hydraulics have settled.
12) I need the operator to match the aluminum storefront on the rest of my doors. What finishes does the 5740K3 come in?
Four finishes: 689 aluminum, 690 dark bronze, BSP black suede powder, and WSP white suede powder. 689 and 690 are the two BHMA codes that carry across most aluminum storefront packages, clear and dark bronze respectively, and the two suede powder coats cover painted white and black frame systems. Finish is the only choice on the 5740K3, so every kit is otherwise identical and a fleet of openings can be ordered in mixed finishes without any other specification changing.
