NFPA2001 automatic extinguishing systems

Question asked by elguasmi.mustapha on Mar 26, 2018

Hello All,

I'm designing an automatic extinguishing system using FM200 gaz. The main problem I'm facing is the authorized configurations for drawing pipe systems (number of branches, number of nozzles per branch...) as with simple configurations like, in the pictures attached, I would get error messages about not authorized junctions.

Is there any rules in NFPA 2001 (or maybe VDS 2381) about authorized pipe schemes for gas extinguishing systems ?


Thanks for your feedback.
