I ran across this device today. The building had a couple of them mounted in ceiling tiles. Anyone have any idea what this is monitoring?

Possibly there is a heat detector above the ceiling tile [or duct detector] and that device monitors the current status, red LED when in alarm.

Doubtful, tpring. The device has vents, which a device monitoring -another- device wouldn't need. Not sure, but that dark spot next to the green LED looks like some kind of adjustment dial.
I have to go with Ron, this is 99% likely to be an acoustic glassbreak sensor, even though I don't recognize the model. If it has a potentiometer adjustment, it's likely to be an old model.
mitigater, how close are you calling "close" to an exterior window? Most GBs are not mounted within a few feet of the glass they're covering--they can be as far away as 30 or 40 feet, sometimes between large windows to cover more than one. Also, GBs sometimes cover interior glass, e.g.an interior office window.
I agree with Ron, best method is to climb up and look for a make & model number on the back.

System sensor piezo alert, likely tied to a duct detector. I believe what looks like a black dot is a red led, which if you were to look closely, likely states alarm underneath.
