About this Manual
This manual is a comprehensive guide that contains all
the information necessary to design, install and maintain
the FM-200
®
Engineered Extinguishing system�� However
the manual does not address information relating to fire
detection��
Users of this manual are assumed to be competent
fire engineers with a basic knowledge of such systems��
The contents are arranged in a logical order describing the
various procedures in turn, alternatively specific sections
can be referred to as required�� Users who are not familiar
with the equipment should first read the complete
manual��

Introduction
FM-200
®
is a clean, safe fire fighting agent for use in total
flooding automatic extinguishing systems�� It is intended
as a long term replacement for Halon 1301 and, whilst
maintaining the excellent fire suppression properties of
Halon, has none of the environmental problems�� Storage
and distribution requirements are similar to Halon and the
majority of system components are identical�� However,
FM-200
®
is not a direct replacement for existing Halon
1301 installations due to the difference in agent quantity
and discharge characteristics�� The minimum FM-200
®
design concentration for Class A hazards is 6��4% for UL
Listed systems or 7��17% for FM Approved systems, and
for Class B hazard is at least 9��0%��
The US Environmental Protection Agency (EPA)
accepts use in normally occupied areas where the
concentration doesn't exceed 9%�� The safe use criteria has
further been confirmed by the Halon Alternative Group
(HAG) report�� Refer to NFPA 2001, 2008 edition “Clean
Agent Fire Extinguishing Systems,” Section 1-5 “Safety,”
for additional exposure requirements��
The systems described in this manual are ‘engineered’��
Engineered systems for example, may consist of several
FM-200
®
containers, modularised or manifolded together
and connected via a pipe network to a number of discharge
nozzles��
Systems may be activated mechanically or electrically��
Mechanical manual actuation is via a manual actuator
attached to the container valve�� Electrical actuation is
via a removable side mounted solenoidor a top mounted
electrical actuator�� Actuation can occur automatically via
a signal from a detection and alarm control panel��
Users of this manual should find that sufficient
information is provided to plan, design, purchase
components, install, operate and maintain the system��
However, in the event that part of the document is not
understood, or if there is any concern as to the suitability
of the protection, do not hesitate to contact one of our
specialist engineers for the matter to be quickly resolved��
Approvals and Standards
The manufactured equipment and the FM-200
®
agent
have comprehensive approvals and listings providing
further support to the overall product��
