It sounds more complicated then it should be which is probably why they might be dragging their feet.

At my school, we have Wheelock ZNS Ceiling mount as well as wall mount, and we have Firelite BG-10L Pull Stations.

My school has a Siemens XLS voice system. Pulls are Siemens HMS-Ds under Stopper covers, and the smokes are Siemens HFP-11s. There are also duct detectors with HFP-11 heads as well. Most of the school has Siemens ZH-MC-R (Wheelock ZNS) horn strobes and Siemens ZR-MC-R (Wheeock ZRS) strobes. The gym, cafeteria, pool, and auditorium have Siemens SET-MC-R (Wheelock E70) speaker strobes. They play the standard Code 3 tone with the female message.

My school has a Gent system, compromising of C3s, Honeywell (rebranded) pull stations and S-quads, as the new additions.

My current place of employment doesn't have a fire alarm system, though in terms of work/school, I always found one of my middle school system's the most interesting.

The system consisted of modern Wheelock NS-24MCW horn strobes in the halls with RSS-24MCW remote strobes in each of the classrooms. Nothing crazy, though next to every bell and alarm in the hallways sat non-functioning gray Standard Electric 4-350s; none in the classrooms except for one. I always thought that those horns were part of the previous system presumably installed when the building was built in the 60s, though I heard that 4-350 in that classroom that I mentioned go off once with the bell system, so I'm completely unsure of their purpose. Was extremely quiet too, as if it wasn't drawing enough current.

My high school also had Simplex 4903-9219s set on continuous with traditional T-bar pulls. Despite the cinderblock hallways, they were much more pleasant on the ears than anything I'd experienced prior.

That system that is in the middle school you mentioned is rather unique, and those non-functioning alarms are probably quite rare in the field.

I did a 'virtual' tour of the university that I'm going to in the fall and wasn't surprised to see that most of the updated dorms have Siemens Cerberus Pyrotronics voice evac systems with rebranded E-50's... along with sounder bases in the dorm rooms. Unfortunately, it looks like they're really pushing to have most / all of their old academic buildings redone for the fall semester. When I took a tour last summer, there were some pretty nice Simplex systems from the '70s and '80s, as well as a few newer Notifier systems that had Spectralert Advances, so it's going to be interesting to see what they decide to do with the renovations. Siemens really seems to be dominating the university market, so I wouldn't be surprised to see all of the buildings have the same setup as the dorms.

In many cases the sounder bases only activate locally. Do the rooms also have speakers in them?

Not that I recall, one of the dorms I looked at had rebranded ZNS strobes in each room along with the sounders though.

Then that means that the sounder bases activate upon any alarm. They sound like U-MMT's.

A surprise at my high school!

This is found at the receiving entrance to the main building. A Simplex 2901-9553 horn on a 4050-80 light plate with the lens missing! The horn is obviously replacing a Simplex 4040 that failed, but what's unusual is how all the other 4040s I've seen at this school are flush-mounted with no visual signals! Then again, this is all I saw of the receiving area. And yes, the original pulls are Edwards 270-SPOs, original to the school's 1969-70 construction with Simplex 4247 systems using 4040 horns (though the main building here has an FCI FC-72 from the early 90s running the system currently.) The school is due for an expansion and renovation soon, so obviously this rarity's days will soon be numbered (along with the city's loudest fire alarm system currently in place!)

I don't really know what else to say, but it's the same horn. At least you've been forewarned.
