CHAPTER 4
DESIGN AND INSTALLATION
4-1 INTRODUCTION
This chapter is intended for system designers and in-
stallers. It outlines the steps needed to design the sys-
tem including the limitations imposed on the design by
the system hardware. The second part of this chapter
explains equipment installation.
4-2 DESIGN PROCEDURE
4-2.1 General
The system design is based on the requirements of Na-
tional Fire Protection Association (NFPA) Standard 2001,
current edition and the Authority Having Jurisdiction (AHJ).
4-2.2 Application
The following steps must be taken to design an
FM-200
®
system:
Determine the design concentration required for the
hazard. Refer to Table 4-2 for Class B hazards.
For systems that protect Class A or Class C hazards,
and incorporate a mechanism of automatic actuation,
a minimum design concentration of 6.25% can be used.
Determine the minimum and maximum ambient tem-
perature for the hazard.
Determine the volume of the hazard.
Determine the integrity of the hazard.
Determine if any additional agent will be required to
offset leakage of agent from the hazard.
4-2.2.1 CALCULATE AGENT REQUIRED
Calculate the quantity of FM-200 required to provide the
proper design concentration at the minimum expected haz-
ard temperature.
Note: Refer to Tables 4-1, 4-2, 4-3 and 4-4. The informa-
tion is given for estimating purposes only. The Kidde
ECS Series FM-200 Flow Calculation Program cal-
culates this information for the designer. Refer to
the Kidde ECS Series FM-200 Flow Calculation
Program User's Manual (P/N 90-FM200M-110) for
further information.
4-2.2.2 DETERMINE WHAT COMPONENTS
ARE REQUIRED
Cylinder size, quantity and fill requirements. Refer to
Tables 4-2 and 4-3.
Cylinder framing, mounting brackets, etc.
Detection and control equipment required.
Other system requirements, such as reserve supply,
pressure switches, etc.
4-2.2.3 LOCATE NOZZLES
Locate nozzles based on the following:
Ceiling height (16 ft. [4.87 m] maximum,
1ft. [0.30 m] minimum).
Nozzle area coverage.
Special hazard area layout considerations.
4-2.2.4 LOCATE CYLINDERS
Locate cylinders based on the following:
Number of cylinders required.
Storage temperature/environmental consider-
ations, such as weather, area classification and
corrosive environment.
Accessibility.
Floor loading.
4-2.2.5 LOCATE PIPING
Locate piping based on the following:
Nozzle location.
Structural members for bracing the pipe.
4-2.2.6 PIPE SIZE AND LAYOUT
Determine pipe size and layout for the following factors:
Draw piping isometric.
Dimensions of all pipe sections.
Locate all fittings.
Note all elevation changes.
The preceding information will be entered into the
computer program.
