The sprinkler industry is constantly evolving because of new advancements in technology and the first edition needs to be revised and updated in conjunction with the 2010 edition of NFPA 13. This most recent edition of the NFPA standard has added requirements and recommendations, and a completely new code numbering system. Technological advances in the fire sprinkler industry will be addressed in the third edition. These include the recently adopted computerized dry-pipe system calculations for water system delivery, and the (accompanying) system test manifold schedule.
