I don’t know for sure, but they are likely used for CO signaling.

90% sure for CO notification, there all on the same addressable loop
Have you seen them go off? Are they hooked up to the speaker/strobes?
No I haven’t, I think they’re controlled by the addressable loop
I wanted to make another post but about my middle schools system. My middle school was built in the late 90’s (1997). When it was built it probably had an EST or a simplex system. But at some point they replaced the system with a Notifier NFS-320C, BG-12’s and gentex Commander 3’s. When the gym was added on, they added a separate voice evac panel (I forgot what brand…) and Gentex speaker strobes. And then in 2021, they built a new addition to the school, It used the same gentex speaker strobes but they were white not red. And last year they added another larger addition. this addition has LED L-Series speaker strobes in both the classrooms and hallway. there is No Annunciator which is confusing because of the panel being far from any entrance doors.
My school has Wheelock AS-241575s, wheelock RSS strobes in the bathrooms, System Sensor 2451 smokes, and bg-10LXs with a Notifier AFP-200 which replaced an old single stroke bell system in 2000, my school was built in 1966
i think the smokes are notifier SDX-551 because its an afp-200
They use System sensor 2451s on the modules for using conventional devices on adressable panels. and in some parts they do use notifier SDX-551s as well so i think they use a mid of both
are the LED’s on the smoke coloured red or clear? it would make more sense to be addressable (sdx-551)
the ones in the hallways are red and the ones in the lobby where the panel is they are clear

My current school has an EST Quickstart QS4 system (circa 2009) with assorted Edwards/GS bells including the Edwards MB10-24, GS MB10-24, and Edwards 439D-10AWC. There are also some Simplex bells & 6 inch bells including the SImplex 2901-9724, Simplex 2901-9723, and GS MB6-24. Pull stations are mainly assorted 270-SPOs or SIGA-270s and there is one Simplex 2099-9754 T-bar pull station. System has a total of 3 remote annunciators.
I don’t mean to be rude, but could you not have put those photos in your initial post instead of two additional ones? (thus making three in all)
They might still have a picture limit per post given that the account was created ~6 days ago.
That’s kinda what I was thinking, but I wasn’t sure if that was the case or not.

If you are wondering why, I posted the text from a device I can’t access my pictures from (school computer), and then I posted the pictures from my phone. The reason why there are 2 posts for just the images, because there is just a lot to upload for just a singular posts.
