No pull stations or anything, they’re set off by pressing the door handle on the fire doors. The one that always goes off is on the ceiling above a glass door that opens into the garden center. I guess people have trouble finding the doors that lead out to the garden center that they’re supposed to use. They really should just have a solid door there so it’s more obvious that it’s not an exit your supposed to use (people don’t read, apparently). Someone said they look look like Tripp-Lite, but I never saw any strobe/sounders that they made, only strobes and an old fashioned fire bell that I saw once. But who knows.
I’ve watched a ton of alarm videos on YouTube, including all those weirid European hi lo alarms, but never seen anything that sounds like this.
They do have actual fire alarms in the store, I’m thinking maybe they were Gentex Commander 3s, or something similar. Never seen those go off. But I’ve always been more interested in those weird strobe horns.
