BEA 10MS51W-S – Frequently Asked Questions

1) Will the BEA MS51W touchless actuator work if I can't run wire back to my door operator?
That's the reason to pick the MS51W over a hardwired switch. It's battery powered and has a 900 MHz transmitter built in, so nothing needs to be pulled from the actuator back to the operator. You mount it where the push plate needs to be, glass jamb, freestanding bollard location, opposite wall, and it talks to the receiver over RF. Battery life is three years, and an LED tells you when the battery is getting low so you're not guessing. You still need a matching 900 MHz receiver on the operator side; the actuator is the transmitting half only.
2) Can a BEA MS51W wireless actuator be mounted outside in rain and snow?
Yes. The enclosure is rated NEMA 4 / IP65 and the operating range runs -22 to 158 deg. F, so exterior entrances and unheated vestibules are in scope. It also has selectable immunity modes that let you tune out false activations from rain, water spray and snow blowing across the sensing zone, which is the usual complaint with exterior touchless plates. Faceplate is stainless steel with an ABS center.
3) Does the MS51W actuator need power at the switch location, or is it fully battery operated?
Fully battery operated at the switch. That's the point of the W version, no rough-in, no conduit, no low-voltage home run to the plate. Three years of runtime per the spec, with an LED battery alert before it dies. If you do have power at the plate location and would rather hardwire, the wired MS51 devices in the same series take 12-24 VAC/VDC or 5 VDC and switch through a 1-Form C solid state relay rated 1 A at 30 VAC/VDC max.
4) How close does someone have to get to the MS51W for it to activate the door?
The sensing zone is adjustable from 2 in out to 24 in. Dial it short in a tight corridor or where people walk past the plate, and dial it long at a hospital entrance where someone is pushing a cart or a bed. Hold time is adjustable 1 to 30 seconds, so you set how long the relay stays made after activation. Detection can run as bidirectional motion, toggle, or timed mode.
5) What's the difference between the hand logo, accessibility logo, plain and text-only faces on the BEA MS51W?
They're the same actuator with a different faceplate graphic, and all four faces are offered on every form factor: Single-Gang, Double-Gang, Jamb and 6 in Round. The accessibility logo (wheelchair symbol) is what most institutional and public-entrance specs call for. The hand logo reads as touchless to the general public. Plain and text-only suit a building where the design team doesn't want the symbol on the wall. Pick the graphic on the specification and the aesthetic, not on function.
6) Is the 6 inch round BEA MS51W suitable for a bollard or post mount at a garage or parking entrance?
The 6 in Round (10MS51W-R) is the form factor for post, bollard and surface mounting where there's no gang box to work with. Body depth is 0.98 in like the rest of the series. With NEMA 4 / IP65 sealing and a -22 to 158 deg. F range it holds up outdoors, and being battery and RF it doesn't need a wire run out to the bollard, which is normally the expensive part of that installation.
7) I'm standardizing touchless actuators across a portfolio of buildings. Can I use one MS51W model everywhere?
One series, four bodies. Every opening type you'll hit is covered by the same MS51W platform: Jamb for aluminum storefront, Single-Gang and Double-Gang for finished wall boxes, 6 in Round for bollards and surface. All four take the same four faceplate graphics, so the accessibility symbol or the hand logo reads identically across every entrance in the portfolio. Settings, sensing range and hold time are common across the series, which means one training pass for your maintenance staff instead of four. Stainless faceplates take the same cleaning routine building to building.
8) Can the beep be turned off on a BEA touchless actuator in a hospital or library?
Yes. Alert settings include a Silent Mode as well as Signal Mode, so you can kill the audible confirmation entirely in a patient corridor or a quiet reading room. The visual indication stays either way: blue in standby, green on activation, which is enough feedback for the user and for a tech checking the device from across the lobby.
