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.

Hell of a system there, Canadian System?


Is that for a shutter?

Most likely a garage door controller.

Yeah it is a Canadian system, and the open/close controls is for a garage door.
