The design concentration for Class A and C fires applies to systems designed to meet and comply with
FM5600, and NFPA 2001, Edition 2015 requirements. As such, our customers are reminded and advised:
• In accordance with 4.3.1.2 and 4.3.1.3 of NFPA 2001, Edition 2015, automatic detection and
automatic actuation shall be used. Manual actuation is permitted only if acceptable by the authority
having jurisdiction.
• Designers should also take note of 4.3.5.6 in NFPA 2001, Edition 2015 with regard to discharge
delays.
• The designer should also review A.5.4.2.4 in NFPA 2001, Edition 2015 and confirm that a protected
Class A hazard does not include any Class B materials (flammable or combustible liquids or gases)
which would classify the protected space as a Class B hazard.
• In addition, the designer should refer to section A.5.6 in NFPA 2001, Edition 2015 and confirm that
the protected space does not include electrical equipment that will not be de-energized prior to or at
the time of Agent discharge. Such energized electrical equipment has the potential to act as a
persistent re-ignition source. If electrical equipment cannot be de-energized, the design Agent
concentration shall be at least that required by 5.4.2.5 in NFPA 2001, Edition 2015. In some cases
consideration should be given to the use of extended Agent discharge or higher design Agent
concentration. When exploring these options, keep in mind the possibility of the formation of
combustion and decomposition products. Please contact applications engineering for design guidance
in such instances.
