Time to revive this thread from the dead, because I have new photos of stuff here (I literally cannot post photos on time for the life of me):
Went to a Carl’s Jr. yesterday, saw this setup. Quite common for restaurants to have this setup.
Then there’s this. An unmarked, very weathered Advance mounted on the ceiling. Spotted at the T-Mobile my family goes to. No clue why they installed it in this manner. No other FA stuff was found there other than this Advance.
Finally, there’s this old smoke detector found in my school’s hallways. Not even sure if it’s a detector of any kind, nor am I sure of its make and model. Found in places like my robotic’s classroom, main office, library, etc. but not everywhere.
Hopefully I don’t delay any further replies by a decade or so
