This is a very badly sun damaged FCI SBS-1201 smoke alarm. That’s what sitting next to a window for 31 years will do to plastic.

Wow…I don’t believe I’ve ever seen a smoke detector as yellowed as that!

I bet the plastic on that detector is brittle as hell
The detector stayed in one piece when it was replaced during a system upgrade. No broken plastic.
Do you have that detector or did they throw it out?
Yes I have it, I saved almost every device on the system in the upgrade here: FCI FC-72 System Replacement Complete
