Its so specialized of an application that it almost isn’t worth the sunk cost to manufacture a device for it. If a ceiling-mounted signal that plays a whoop tone is truly needed (in the context of fire alarm, almost never; in the context of general signaling, once in a blue moon on Friday the 13th when all the planets are aligned), they’ll just as soon mount a wall-mount unit on the ceiling and go with that. For general signaling it doesn’t really matter that they’re using a wall mount device on a ceiling since it isn’t being used as a life safety device.
You aren’t exactly a product design engineer yourself so you are probably no more qualified than one who actually is and probably knows a lot more about what is needed in a general signaling alarm.
Hell, I’ve seen grocery store theft sensors use green-strobe white Commander 3s set to temporal chime just today in fact. Not at all how I’d set it up but that’s not my discipline nor my wheel house.
