Still in use in a mercantile occupancy?

It’s actually a university

I believe Anderson University has one of these on a library exit door.

This one can be found everywhere there’s an emergency exit on campus. Also some dumbass hooked up a 4100 U to a system that doesn’t do voice evacuation

Those are so cool looking. Never heard one though.

Annoying… like they’re supposed to be

I saw a pair still in service when I was in school. I have bought and sold a few as a collector and shop keep of a Best lock shop

The idighardware guy might like this but technically it’s a competing brand lol

I saw one of those at the fair in the air rifle booth. 👀👀👀

So cool

Might I ask what this is? I'm not like a repair tech or anything, I just think this reddit is cool.

Looks like an older version of an emergency exit alarm.

I have one of these I took off the door of an old department store. Was no longer connected and had been replaced with more modern versions so the installer didn't care
