In my school:
NAs:
Simplex TrueAlerts in the main academic buildings set on code 3
Wheelock MT horns on all exterior walls (and a ceiling mount, indoor MT horn/strobe on an outdoor wall), all set on continuous
Faraday/FOS horn/strobes and remote strobes in the gym building and the rotunda building. I haven’t heard them before, but I assume that they are on code 3
Some weatherproof Gentex Commander 2 horns (one red, one white), probably also on code 3
A couple of sprinkler bells (I don’t know the manufacturer or model, likely Wheelock) outside. They are likely on continuous.
Unknown panel: likely Simplex
Annunciators: The only one I have seen is a Radionics annunciator by the door to the gym
Pull stations:
Simplex T-bars in the library, cafeteria, and by the elevators
A few Edwards 270-SPOs in the gym
A rebranded Bosch dual action pull station in the gym (More details in another post of mine: Bay Alarm pull station - #8 by SpruceParsleyAlarms )
I don’t know if this counts, but an Ansul or similar fire suppression pull station in the kitchen
A Potter FA-50 on the outdoor patio which is kinda yellowed.
Some FCI MS-2s in an academic building
Detectors:
Likely Simplex, but I haven’t been able to look closely at the detectors
