Anybody recognize this “mystery box”?
I was studying the water pump & related today, so that I could feel ready to perform a swap if necessary while on the road.  I don’t have any idea what this white box is (between the water pump & the electrical panel).  It looks like a speaker or alarm of some sort.  I’m guessing the original owner had installed it.

Any of you know what it is?

I’m guessing it’s a moisture alarm in case the water pump or related piping leaks. Looks like an isolation valve was installed as well, which is good!

It's a water alarm. Held in place by a couple of Velcro dots, so you should be able to pull it right off. It probably needs a new battery.

Looks like this one:   THE BASEMENT WATCHDOG Model BWD-HWA 110 dB Battery Operated Water Alarm -... 
As Andy said it probably needs a battery.
       Since it is next to a 12vdc source, you could use this one:  12V DC Wired Water Detectors Water Leak Alarm Module Leakage Flood Sensor...  Double the price, but no battery required.  RonB

I bought a 2-pack of these, one for the water pump area and the other under the water heater.

In both of my Lazy Daze coaches I installed this style water sensor.

<Reliance Controls THP205 Reliance Sump Pump Alarm with Flood Alert, 9 V...;

I placed the sensor element on the floor by the water pump and the other on the floor under the sink and next to the  water heater. What I liked was that the electronics and battery case could be placed in a location easily accessible to annually change the battery. Also the alarm sound would not be muffled by cabinetry.

Yes, I like the separate sensor type. That's what I used in Skylark.

Andy,  I think I got the idea from your post many years ago and it made good sense! I will be using the same with my new Coach House when the time comes.
Again, Thank you!!
