I second Jim Robert's motion. To answer your question, though, I don't consider computer equipment as being susceptible to deep seated fires. On the other hand, I have seen pallets of paper, overflowing bins and office furniture in such places.. [EMAIL PROTECTED] Ed Vining 4819 John Muir Rd Martinez CA 94553 925-228-8792

I would consider a clean agent sytem per NFPA 2001. Hopefully, this is only a back-up to a wet pipe system, which is still my favorite.

My questions are as below: 1)- Is a computer room fire a deep seated fire? 2)- NFPA 12 states that "For deep-seated fires, the design concentration shall be achieved within 7 minutes, but the rate shall be not less than that required to develop a concentration of 30 percent in 2 minutes." Is it a problem if the total discharge time would be only 1 minute for this case? Many thanks for your help in advance.
