More Unknown Fire Alarms!

I found more fire alarms/smoke detectors that I need answers to.
Is this rare?


What type of fire alarm box is this? I found it at my school building.

Thanks for the help.

Can’t really say for sure about the TA (since we’re not allowed to say the brand here) smokes but that FA box is one of those “coded” stations. Something you don’t see that much anymore, if it’s possible, try and ask if you can salvage it when it’s going to be taken out!
