MS Sedco 59R4-HSS – Frequently Asked Questions

1) Will the MS Sedco 59R4 push plate mount to a standard single-gang electrical box?
Yes. The 59R4 round push plate attaches directly to a standard single-gang electrical box, which is what makes it straightforward on retrofits where the wall box is already there. If you are surface mounting instead (block wall, glass mullion, no back box), it also mounts to the MS Sedco #1025 surface box, which is a separate order.
2) What are the switch contacts and electrical rating on the 59R4 push plate?
It uses a UL Listed SPDT momentary microswitch rated 15A at 125VAC, wired out as NO, NC and COM on wire leads. Momentary means it closes only while pressed, which is what an automatic door operator or low energy controller expects. Having both NO and NC available lets you land it on operators that want either polarity, and the 15A rating means it is not limited to dry low voltage signalling.
3) Can I use the 59R4 push plate outdoors or in a wash-down area?
Standard 59R4 plates are not weatherproof, but an IP68 weatherproof option is offered for exterior, wet, or wash-down locations. If the plate sits on the outside of an exterior vestibule door, on a garage entry, or anywhere it sees hose-down cleaning, specify the IP68 version rather than the standard plate.
4) What is the closest alternative to the MS Sedco 59R4 push plate switch if the opening calls for a square plate instead of a round one?
The MS Sedco 59R4 uses a 4 inch round all-active face plate with a 4-1/2 inch formed stainless steel back plate. If the specification or the existing wall cutout calls for a square plate at the same nominal size, the Camden CM-46 Series is a 4-1/2 inch square push plate switch. Both are wall-mounted actuators for automatic door activation; the difference a buyer is choosing on is plate geometry - round face versus square face - and how that reads against adjacent plates already on the building.
5) What are the actual plate dimensions on the MS Sedco 59R4 round push plate?
The face plate is a 4 inch round all-active plate, meaning the entire face triggers the switch rather than a small button area. Behind it sits a 4-1/2 inch diameter formed stainless steel back plate that takes the wear and keeps hands and wheelchair footrests off the wall finish. Plan your wall layout around the 4-1/2 inch circle, not the 4 inch face.
6) What finish and legend combinations does the 59R4 come in?
Three: stainless steel with a blue legend, stainless steel with a black legend, and a blue background with a white legend. The stainless versions use an etched and paint-filled legend; the blue one is powder-coated aluminum with an engraved legend. Pick by what is already on the other openings in the building so the lobby reads consistently.
7) Is there a wireless version of the 59R4 if I cannot run wire to the plate?
Yes, radio control versions of the 59R4 are available for wireless activation. That is the usual answer on a finished lobby wall, a glass entry with no path for conduit, or a bollard mount across a vestibule. Note that a wireless plate still needs a matching receiver at the door operator, so it is a two-part order rather than a plate on its own.
8) Round or square push plate for an ADA accessible entrance?
Function is identical; the choice is architectural and about how the plate sits on the wall. The 59R4 is the 4-1/2 inch round format with a full all-active face. If the building is already standardized on square plates, the Camden CM-46 Series is a 4-1/2 inch square push plate of the same footprint dimension. Either way, the all-active face on the 59R4 means a forearm, elbow or closed fist anywhere on the plate triggers it, which is what matters on an accessible entry.
9) Is the Camden CM-46 push plate fire rated, and does the MS Sedco 59R4 carry a fire rating?
The Camden CM-46 Series is listed as not fire rated. The MS Sedco 59R4 is a commercial-grade actuator whose stated listing is a UL Listed SPDT momentary contact microswitch rated 15A at 125VAC - that is a switch listing, not a fire door assembly rating. If a fire-rated opening is in play, the rating is carried by the door, frame and the automatic operator assembly, and the actuator should be selected to match whatever the operator manufacturer permits on that assembly.
10) We already have square 4-1/2 inch actuators on the other entrances - can we mix in a round MS Sedco 59R4 without a wiring change?
Electrically the switch type is the deciding factor, not the plate shape. The MS Sedco 59R4 carries a UL Listed SPDT momentary contact microswitch wired NO/NC/COM with wire leads, which is the standard dry-contact arrangement automatic door operators accept, and it mounts to a single-gang electrical box or the MS Sedco #1025 surface box. The Camden CM-46 Series is the 4-1/2 inch square equivalent in plate format. So the practical choice between them is visual consistency across the fleet and the existing box or cutout, with the operator wiring terminations handled the same way in either case.
11) Is the 59R4 rated for use on a fire rated door opening?
Treat the 59R4 as a standard commercial activation switch, not a fire-rated assembly component. Among comparable push plates, the Camden CM-46 Series is likewise recorded as not fire rated. Push plates are wall-mounted and sit off the door itself, so on a fire opening the rating question belongs to the door, frame and operator hardware, not the actuator on the wall.
12) Is the MS Sedco 59R4 suitable for a high-traffic healthcare or school entrance?
That is exactly what it is built for. It is a commercial-grade device with an industrial microswitch behind an architectural face, and the oversized 4-1/2 inch stainless back plate is there specifically to stop wall damage where the plate gets hit hundreds of times a day. Common placements are hospital corridor and department doors, school accessible entries, office lobbies, and multi-tenant residential lobbies.
