I think what you've got there is a Star sprinkler from the 70's or so, before the development of the first residential sprinklers and the fast response link.
It was early attempt to make a quick response sprinkler. The linkage was a standard response but the thing beside it is a squib that (as I understand it) is supposed to send an hot electric arc to the link to cause it to melt out/actuate quickly. I only every saw them on one installation and I was once told that handling them should be like handling explosives, because an accident with that squib could do some harm.

I'm hoping someone knows what it is because we have been unable to find it online. http://i.imgur.com/ZqsFu39.jpg Thanks!
