The system and its components are agency tested for total flooding applications and should be used in accordance with the guidelines contained in National Fire Protection Association Standard 2001. A total flooding application can be defined as injecting FM-200 into an enclosure or volume having the structural integrity to retain the agent during and after discharge. The design of such a system requires that the FM-200 chemical agent be discharged from its container within 10 seconds and be thoroughly mixed throughout the protected volume, reaching a minimum concentration level of 6.25%, but not exceeding 9% in normally occupied spaces.
