BEA 70.5872 – Frequently Asked Questions

1) What faceplate shapes does the BEA MS31 motion sensor come in, and how do I pick one?
The MS31 microwave motion sensor faceplate is offered in four mounting formats: jamb, single-gang, double-gang, and 6 inch round. Pick by what the sensor is mounting into. The jamb plate is the narrow one for mounting on a door frame or mullion. Single-gang and double-gang drop into standard electrical box openings, so if the wall already has a box roughed in, match the plate to the box you have. The 6 inch round is the surface plate for locations with no rectangular box behind it.
2) Does the BEA MS31 faceplate come with the handicap logo, and can I get one with no markings?
All three markings are available on the MS31 faceplate: the handicap (ISA) logo, text with a hand logo, and plain with no graphic at all. Every one of the four plate shapes (jamb, single-gang, double-gang, 6 inch round) is offered in all three markings and in all three colors, so a plain grey single-gang or a handicap-logo 6 inch round in black are both real combinations. Facilities standardizing on unmarked plates for aesthetic reasons can order plain throughout.
3) How far away does the BEA MS31 touchless sensor detect a hand?
Detection range is adjustable from 4 to 24 inches, using microwave Doppler radar at 24.125 GHz with bidirectional motion detection. That short range is deliberate: it keeps the sensor from firing at people walking past in the corridor and only responds to a hand, cart, or wheelchair deliberately presented at the plate. Set it toward the short end in a tight vestibule where traffic passes close to the wall.
4) Does the BEA MS31 touchless switch meet the ANSI 156.10 knowing act requirement?
Yes. The MS31 microwave motion sensor is adjustable to comply with the ANSI 156.10 knowing act standard, which is what an inspector looks for on a powered pedestrian door activated by a wall switch. Compliance depends on how the range is set during commissioning, so the adjustment has to be made at install, not assumed out of the box.
5) What voltage does the BEA MS31 motion sensor run on, and what can its relay switch?
Supply is 12 to 24 VAC (+/-10%) or 12 to 24 VDC, at 50 to 60 Hz mains frequency, drawing under 1.5 W, so it runs off the accessory power on most low voltage door operators or a standalone transformer. The output is a voltage-free relay with a switch-over contact rated 1 A resistive, up to 60 VDC or 125 VAC, and a maximum switching power of 30 W DC or 60 VA AC. Because the contact is dry, it drops into an operator input or an access control panel without needing matched voltage on both sides. Pulsed mode holds the output for 0.5 seconds.
6) Can I just replace the faceplate on my existing BEA MAGIC SWITCH sensor instead of the whole unit?
Yes, that is what the MS31 Series faceplates are for. They serve as replacement or upgrade components for BEA MAGIC SWITCH microwave motion sensors, so a scratched plate, a marking change (swapping plain for the handicap logo), or a color change to match a renovation can be done without pulling the sensor and rewiring. Confirm the plate format matches how the existing sensor is mounted (jamb, single-gang, double-gang, or 6 inch round) before ordering.
7) Can a Trine 4100 Series CC faceplate be used in place of a BEA MS31 faceplate?
No. The Trine 4100 Series CC faceplate is a 4-7/8 in x 1-1/4 in center cavity faceplate for an electric strike, so it mounts in the strike prep in the frame and covers the strike cavity. The BEA MS31 faceplate is the cover for a MAGIC SWITCH microwave motion sensor that provides touchless activation using microwave Doppler radar at 24.125 GHz with an adjustable 4 in to 24 in detection range. They sit at different points in the opening - one finishes the latching hardware, the other finishes the activation device - and neither part fits the other's prep.
8) I need a faceplate for a fire rated opening - is the BEA MS31 faceplate the right part?
For the latching side of a fire rated opening, the faceplate that carries the rating is the strike faceplate. The HES Folger Adam 700 Series faceplate is fire rated and Grade 1, and it is the part that goes in the frame prep at the strike. The BEA MS31 faceplate is the cover for a microwave motion sensor that activates the door; it is the touchless activation device, adjustable to meet the ANSI 156.10 knowing act standard. On a fire rated opening that also has touchless activation, both parts are in play and they are ordered separately.
9) My electric strike faceplate is damaged and the sensor plate is cracked - are these the same order?
They are two separate parts. Electric strike faceplates are ordered by strike series - the Locknetics CCFP-KIT covers CS Series strikes, the NCCFP-KIT covers NC Series strikes, and the MDSFP-KIT-10B covers MDS Series strikes - so the strike model on the frame determines which kit fits. The BEA MS31 faceplate replaces the cover on a MAGIC SWITCH MS31 Series microwave motion sensor and is chosen by mounting style and marking instead: jamb, single-gang, double-gang, or 6 in round, in black, grey, or white, with plain, text and hand logo, or handicap logo.
10) What colors do BEA MS31 sensor faceplates come in?
Black, grey, and white, and each color is available across all four plate shapes and all three logo options, which is 36 combinations in total. If you are matching existing switch plates down a corridor or standardizing a hospital wing, you can hold one color across jamb-mounted and gang-box-mounted openings without a mismatch.
11) What gauge wire do I run to a BEA MS31 sensor?
Standard cable up to 16 AWG (1.5 mm2) lands in the MS31 sensor terminals. That covers the 18 AWG multiconductor most low voltage door control gets pulled in, so an existing run to a push plate location is usually reusable when converting to touchless.
12) Can a BEA MS31 touchless sensor be mounted outdoors or in an unheated vestibule?
Operating temperature runs from -4 to 131 degrees F (-20 to 55 degrees C), which covers an unheated vestibule, a parking garage entry, or a loading dock in most climates. The housing is ASA, nylon, and PC. Note there is no ingress rating stated for direct water exposure, so treat it as a location that stays out of driving rain.
13) Should I use a touchless microwave sensor or a push plate for an automatic door?
A push plate is a mechanical switch someone has to contact; a microwave sensor like the MS31 activates on motion within an adjustable 4 to 24 inch field, so a hand, cart, or wheelchair triggers it without touching anything. Choose touchless where hygiene drives the decision: hospitals, pharmacies, clean rooms, and foodservice, plus high traffic retail and transit where reducing touchpoints matters. A push plate remains simpler where contact is not a concern and you want a purely mechanical failure mode. Both can be applied to meet ANSI 156.10 knowing act operation; on the MS31 that comes from setting the detection range correctly.
14) For standardizing faceplates across a facility, can one part number cover both the strikes and the touchless activators?
No, and they standardize on different keys. Strike faceplates standardize by strike series - Locknetics CS Series openings take the CCFP-KIT and NC Series openings take the NCCFP-KIT, and an HES Folger Adam 700 Series opening takes a 700 Series faceplate, Grade 1 and fire rated. Touchless activation standardizes by mounting and marking, which is why the BEA MS31 faceplate is stocked in jamb, single-gang, double-gang, and 6 in round formats in black, grey, and white. A facility standard usually names one strike faceplate per strike series and one MS31 color and marking combination for all activators.
