Yes. I have replaced some of the old off on heads. These are just standard brass upright heads. They have a fusible link that is circular and looks like a cup. In a message dated 1/6/2012 3:49:10 P.M. Eastern Standard Time, [email protected] writes:
The only GEM head I'm aware of being recalled was the old "on-off" head which would be pretty rare I would imagine. Mike Morey, SET, CFPS Sprinkler Designer BMW Constructors, Inc.

I looked as well as possible in the trash collector. Unfortunately by the time I arrived the trash chute had already seen its share of additional trash. I was not about to go fishing through the garbage. I could definitely stub a new head out there. I'm not sure if it is really necessary as there are heads on the individual floors already, including the top floor, just a few feet from this mystery head. If it just a cleanout head, I will leave it plugged. I have one other issue in this building which is adding to the confusion. They had a head go off for no reason a few months ago in a common area. The head made a real mess and now they are convinced they have faulty sprinkler heads. There was no fire, it didn't freeze, and it was in an area that it couldn't have been hit by accident. I believe they were Gem heads, from the 80's. The head in the chute does not look like a Gem head. It looks older than the one that fused in the common area. The owners are convinced all the heads in the building may be faulty. Does anybody know of any Gem recalls? I know Central had a major recall. I also remember sending a sampling of older heads out years ago for testing. Does anybody know if they still test heads? This building is becoming a real headache. Between the fusing heads and some fire pump issues which I won't get into. Any help would be appreciated. -------------- next part -------------- A non-text attachment was scrubbed...
