Relay?

I took this from my school with the system replacement.


What is this relay? Like the brand, use for it or whatever?
I would greatly appreciate any help

where did you find the relay?

It was in a box with the panel. The school was built in ‘78 with an old simplex panel. Idk what but that’s the brand. Then it was replaced by an est 3. But I’m assuming that’s an older simplex relay. Idk

They just replaced the entire system this time.

I can’t make out the brand, and since relays can basically be used for anything, you’d have to see what it’s connected to. It might be signal coding.
