I think a 5lb. system should have a full bottle weight of 7-9 pounds, so if yours only weights 4 pounds, it is missing most or all of its contents. I haven't seen an FM100 system for a long time - and there's a reason. They were specifically outlawed in the GCR as of 1/1/97. I remember because my buddy I mentioned earlier had to replace his with halon back then. It's been so long ago, the prohibition was left out of the latest revised fire system rules. Makes me wonder how it has passed annual tech over the last 13 years.
