1 GENERAL INFORMATION
e Janus Fire Systems® Sv, Mv, and Lv Series Fire Extinguishing Systems utilize FM-200® to protect
high value assets in areas that may be normally occupied, in locations where clean-up of other agents is
problematic, when storage space for a re suppression agent is restricted, and/or when an electrically non-
conductive agent is required.
FM-200® systems may be used in Class A (wood, paper, cloth, rubber, and many plastics), Class B (ammable
liquids and ammable gases), and Class C (energized electrical equipment) surface res.
NFPA 2001 mandates that clean agents such as FM-200® shall not be used on res involving the following
materials unless they have been tested to the satisfaction of the authority having jurisdiction:
• Chemicals or mixtures of chemicals, such as cellulose nitrate and gunpowder, that are capable of rapid
oxidation in the absence of air
• Reactive metals, such as lithium, sodium, potassium, magnesium, titanium, zirconium, uranium, and
plutonium
• Metal hydrides
• Chemicals capable of undergoing autothermal decomposition, such as organic peroxides and
hydrazine
All systems described in this manual are intended only for total ooding application. NFPA 2001 denes
total ooding as the act and manner of discharging an agent for the purpose of achieving a specied minimum
agent concentration throughout a hazard volume. e FM-200® must be discharged within 10 seconds and
reach a minimum concentration level of 6.7% but not exceeding 9% in normally occupied spaces.
Note: Janus Fire System® Fire Extinguishing Systems are designed, manufactured, installed and UL listed
and FM approved to deliver a designated quantity of FM-200® in a "not to exceed" 10 second discharge
time. e "Duration of Protection (Hold Time)" as referenced in NFPA 2001, 2012 edition is a function
of the hazard enclosure's (room) integrity and not a function (or capability) of the re suppression systems
referenced in this publication.
