From an interview with a teacher that went to that high school as a student a long while ago, his name was Trey (he’s my bus driver), I asked him if the alarm sounded anything like a “game score buzzer,” to which he replied, after thinking about it for a minute, “yes.” So, it may be AC. I have no idea if it has terminals (model has the ‘T’ moniker) or pigtails (no ‘T’ moniker) though, nor if it’s a rebrand (I’ve seen countless).
I also asked Trey if he knew what the pulls looked like, then I made an educated guess and asked him to search up “Ellenco 5C.” He looked at the images that appeared in the results and he said “yep, that was it.” So my “educated guess” is supposedly correct, therefore the previous pulls were Ellenco 5Cs.
By the way, if anything, you’ve probably seen the projector in BlackLightning 4547’s video review of his Notifier rebranded 33-24.
Funnily enough, the system was replaced with Wheelock alarms too. I own some from my school: a Siemens SE-MC-CW (E60-24MCC-FW), ZH-MC-R (ZNS-24MCW-FR), and a Faraday 8700-S (the pulls are actually HMS-S but mine so happened to be a Faraday 8700-S). The system is a Siemens Cerberus with a Faraday VPD (EVAX) voice panel. Speaking of, we’re supposed to have a fire drill today or tomorrow.
