Fire Pump System for Pressurized Hydrant, Wet Riser and Sprinkler System

Dear Sir,

I am an NFPA member and my membership # 2715059.


I am working on the design of Fire Pump System for a Power Plant whereby there is a comment from the local AHJ in Malaysia.

 

Under the NFPA 850, 20, 25, 14 and 13 is there any requirement that the common Fire Pump System (Electrical and Diesel plus Jockey Pump) which is sized with a 15% capacity and a total water demand which is sized with a 100% standby water capacity that is sufficient for 2 hours or more can be designed to be used for the the following :-

 

a) Combination of Pressurized Hydrant and Sprinkler System?

b) Combination of Pressurized Hydrant and Hose Reel System?

c) Combination of Wet Riser and Sprinkler System?

d) Combination of Wet Riser and Pressurized Hydrant?      

 

Is there any clauses in the NFPA that this is all allowed or we have to use a separate pump system with a dedicated water tank for Pressurized Hydrant and Sprinkler System and Wet Riser and Pressurized Hydrant?   

 

Appreciate your confirmation and feedback on the above queries.

 

Best regards,

 

Chong Yin Keong
