BEA 10MS31U-B – Frequently Asked Questions

1) Will the BEA MS31 touchless actuator fit a standard single gang electrical box, or do I need a different plate?
The MS31 comes in three plate formats and you pick the one that matches your box or jamb. The single gang plate measures 2.75 in W x 4.5 in H x 0.98 in D, the double gang plate 4.5 in W x 4.5 in H x 0.98 in D, and the narrow jamb plate 1.68 in W x 4.5 in H x 0.98 in D for mounting on the frame itself where there is no wall box. All three are the same 4.5 in height and 0.98 in depth, so switching format changes the width only. There is also a round plate version. Order the plate style as an option along with the color.
2) What voltage does the BEA MS31 microwave actuator need, and can I run it off my existing door operator's accessory power?
The MS31 runs on 12 to 24 VAC or VDC, or 5 VDC, drawing under 2.8 W. That range covers the accessory output on most low energy operators, so in most cases you can power it from the operator rather than pulling a separate supply. Confirm the operator's accessory terminal falls in that 12 to 24 V window and has the current headroom before you land the wires. The unit ships with a 12 in wire harness, so plan your box or jamb penetration within that reach or splice in a longer run.
3) Can I mount a BEA MS31 actuator outdoors on an exterior entrance?
Yes. The MS31 carries a NEMA 4 / IP65 enclosure rating and an operating range of -22 deg F to 158 deg F, so it is rated for exterior jambs and walls exposed to weather and washdown, and it will hold up through a northern winter. The stainless steel faceplate with an ABS center is the exterior-facing surface.
4) Does the MS31 touchless switch meet the ANSI 156.10 knowing act requirement?
It can be configured to. The MS31 is a microwave sensor with an adjustable sensing zone of 2 in to 24 in, and BEA states the device is capable of ANSI 156.10 knowing act standard compliance when set up accordingly. The compliance depends on how you set the range, not on the box it came in, so tighten the zone down during commissioning rather than leaving it wide open. Document the setting after final test.
5) Can the BEA MS31 switch a maglock or door strike directly, or do I need a relay in between?
The MS31 has a 1-Form C solid state relay rated 1 A at 30 VAC/VDC maximum. That is a dry contact suitable for signalling an operator or access control input, and it will carry a small load directly. It will not carry a typical magnetic lock or a continuous-duty strike, both of which exceed 1 A inrush or run above 30 V. For those, switch an interposing relay or a lock power supply input with the MS31's contact instead of wiring the lock through it.
6) Should I use a microwave touchless actuator or a push plate for a hospital corridor door?
A microwave actuator like the MS31 removes the touchpoint entirely, which is the point in healthcare, foodservice, and clean room work. It uses Doppler radar and detects motion, so a hand, a cart, or a wheelchair passing through the zone triggers it. A mechanical push plate needs contact and physical force. The tradeoff is setup: a radar sensor has to be range-tuned so it fires when someone reaches for it and not when a gurney rolls past in the corridor. The MS31's zone adjusts from 2 in to 24 in for exactly that, and it can be set to toggle or timed mode instead of straight motion.
7) How long does the BEA MS31 hold the door open after someone waves at it?
Relay hold time is adjustable from 1 second to 30 seconds. The short end suits a straight momentary trigger into an operator that runs its own open timer, and the longer settings suit an opening where the actuator itself has to hold the signal, like a vestibule or a door someone is pushing a cart through. Set it during commissioning along with the detection range.
8) What colors and plate styles does the BEA MS31 actuator come in?
Nine combinations: black, gray, or white, each in jamb plate, round plate, or single and double gang plate. That means a facility standardizing on one look can carry the same color across a narrow jamb mount and a wall box mount without a visual mismatch. All formats share the stainless faceplate with ABS center construction.
9) Does the BEA MS31 give any feedback so a user knows it registered them?
There is both a visual and an audible cue. The LED shows blue in standby and green on activation, and the audible alert can be set to silent mode or signal mode. Silent is the usual choice in a hospital ward or a library; signal mode is worth turning on where ambient noise is high or where users need confirmation before they walk into the door.
10) Is the MS31 a two-way sensor, or does it only trigger from one side?
Motion detection on the MS31 is bidirectional, so it fires on movement toward or away from the sensor rather than requiring an approach from one direction. If you want it to respond only once per presentation instead of re-triggering on every pass, switch it out of motion mode into toggle or timed mode.
