How does a deluge valve differ from a standard alarm valve in a wet system?
What are differences from a standard wet pipe system regard alarm trim and NPFA codes
Also if an existing system, over 2000sft, (pipe sched method) has no siamese connection, and I am adding addtional heads via the same pipe schedule method - Am i required to upgrade the riser/alarm trim to include a fire department connection? - (re:NFP13, 2002)
