Foam System Redundant Fire Pump

Group, In NFPA 409 (2004) I see reference to sizing of redundant fire pumps Air Force ETL 02-15 but I'm missing the section that specifically requires the redundant fire pump for a group I hanger. Can someone help me out? Thank you, Ryan Peterson Wayne Automatic Fire Sprinklers Office 407

RE: Concealed Space?

Look at NFPA 13 8.15.22.3 2010ed. Note that the section only says only on one side so I'm not sure it would apply to your configuration. Next option is Vertical Openings 8.15.4. Ryan Peterson Wayne Automatic Fire Sprinklers -Original Message- From: sprinklerforum-boun

Re: NFPA 13 apartments - calculating the garage

You are correct since it is ordinary hazard you need a one hour rated wall and an automatic or self closing door of equal rating. Since it was the AHJ's decision to not recognize 13R I would ask them for guidance or engineer a solution and submit it to them for approval. Ryan Peterson, Design

RE: residential heads / 4 head calc

If your using residential heads it's the 4 most demanding sprinklers regardless of whether they are in the same room or not, see NFPA 13 2002 figure A.11.2.3.5.2. You could apply the room design method, per 11.2.3.3, if your not using residential heads. Ryan Peterson Wayne Automatic Fire
