NEMA SB 20:2015

This guide covers activation, operation, and testing requirements for smoke control systems in all types of buildings. PURPOSE This document was developed to provide readers with an understanding of the purpose and general operational requirements for smoke control systems and to allow the reader to identify appropriate test methods based on the specific design objectives of each system. It should also provide an understanding of how smoke control systems deliver the reliability necessary for a life safety system, using an approach that is different from what readers might be familiar with from other types of life safety systems.
