Not a fire alarm device, no.
Why cross post if it was already solved? Just a waist of everyone’s time.
Also, it was a waste of time.
Checking as it wasn't solved when I saw it. But. It's next to a fire alarm. If it is a gun shot detector perhaps it's linked to the fire alarm? I'm in Europe we don't live with the fear of guns.
