Rare 120VAC Simplex 2903 9150 Strobe + 2901-9525 Fire Alarm (Former Danbury HS Fire Alarm) 

Really cool! Looks like a 2903-9101+2901-9833 while it's not.

Cool! I've never seen an AC 2903 with an AC 2901 on it

I love that!

oh it’s like whoever posted the vid of the faraday horn strobes that resemble the rebranded 9833 and 7002 top-mount strobes I got a faraday ac horn/strobe like the ones with the diagonal vents sounds the same but isn’t as cool not exactly vintage like this just discontinued

I thought the 9525 had the older cover and the 9517 had that cover.

Nice horn

Very trippy lol, don’t usually see AC versions of the 2903.

WOW! Must've been from a different part of the building, because this video shows 2901-9838's on FWR: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-u17wVyukhx0.html

You have GOT to put a 4050 and a dual projector on that 2903.

This is incorrect, Danbury HS had DC 2903s (2903-9101s) and later in 2016, the system was replaced with advances Here is my proof: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-u17wVyukhx0.htmlsi=5BSUq3tFy0UM2zFE
