CHAPTER III
SYSTEM DESIGN
General
Pyro-Chem Industrial Vehicle Paint Spray Booth Fire
Suppression System has been designed and tested for use
in commercial vehicle paint spray booth applications. The
guidelines listed in this chapter deal with the limitations and
parameters of various system configurations. It is the
responsibility of the Certified installer to ensure that the
proper system design is being utilized, and that the system
meets the limitations and parameters listed in this chapter.
Before attempting to design any system, it is necessary to
attend a Factory Certification Training Class and become
Certified to install Pyro-Chem Industrial Vehicle Paint Spray
Booth Fire Suppression Systems. Because it is impossible
to completely understand every aspect of a pre-engineered
system simply by reading the Technical Manual, Pyro-Chem
will not be responsible for system design, installation, or
maintenance performed by any non -Certified person(s).
Choosing the Proper Agent
Designing the Proper Type of System
It is necessary for the system designer to consider the phys-
ical characteristics and layout of the hazard area to ensure
proper protection. The hazard area must meet the criteria for
a particular system for that system to be effective. Each noz-
zle is tested and designed to protect a certain part of the
total hazard area.
In order to comply with the approval requirements of UL
1254 Standard, when protecting a Vehicle Paint Spray
Booth, no unclosable openings are allowed.
The system must also contain a discharge time delay.
The ventilation system must be shut down before or simulta-
neously with the discharge of the system.
Total Flooding
It is necessary for the system designer to consider the com-
bustible material found in the hazard area to ensure proper
a. Cylinders:
protection. The agent used in the system must be approved The Models PCI-15ABC, PCI-17ABC, PCI-25sABC, PCI-
for the hazard class of the combustible material. The follow- 35ABC, and PCI-70ABC cylinders can be used for total
ing are the hazard classes: flooding vehicle paint spray booth applications.
A" Class - Ordinary solid carbonaceous combustibles. b. Nozzles:
These include wood, paper, cloth, fiberglass, and plastics Five nozzles are available for use in protecting vehicle paint
spray booths:
B" Class - Flammable liquids and gases. These include
paints, solvents, gasoline, oils, and hydraulic fluids. Nozzle Application
C" Class - Electrical appliances. These include comput-
ers, power generators, and power transformers.
D" Class - Combustible metals such as sodium, potassium,
magnesium, titanium, and zirconium. The Pyro-Chem
Industrial Vehicle Paint Spray Booth Fire Suppression
System is not intended to protect Class D hazards.

N-DCT Duct Only'
Can be used with PCI-15ABC and PCI-25sABC cylinders only
The following guidelines should be used for determining the C. Temperature Range:
proper agent: The operating temperature range for vehicle paint booth
applications is 32 *F. to 120 "F. (0 *C. to 48 *C.),
ABC (monoammonium phosphate -based) - for use with all
A", "B", and "C" Class hazards. d. Piping Requirements:
As per NFPA 17, pre-engineered dry chemical systems are
not approved for deep-seated or burrowing fires (such as
ordinary combustibles where the agent cannot reach the
point of combustion), or on chemicals that contain their own
oxygen supply (such as cellulose nitrate). Do not mix differ-
ent types of agents, or agents from different manufacturers.
Chemical reactions may occur when incompatible chemicals
are mixed. Keep in mind that the agent must be accept-
able to the Authority Having Jurisdiction.
Piping diagrams include limitations on pipe length and fit-
tings. See the following pages for specific piping design and
limitations for each size cylinder.

e. Nozzle Placement:
The nozzle is to be mounted in the center (See Note) of the
protected area, with the discharge holes in the nozzle no
greater than four (4) inches from the ceiling. For duct pro-
tection, the nozzle is to be mounted in the center. See

NOTE:
1. These limitations apply to PCI-17ABC using two nozzles (any combination of either NV-P1, NV-UF, or NV -DP).
2. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length
from ,T1 to nozzle and the longest actual pipe length from T1 to nozzle does not exceed 10% of the longest actual pipe
length from T1 to nozzle. The number and type of fittings for all T1 to nozzle sections must be equal.
3. A Main/Reserve Tee Check, Model TC-1, may be located between the cylinder and T1, and counts as two elbows in that
section.
4. All systems protecting vehicle paint spray booths require a factory pre-set time delay.
5. When using an NV -PI nozzle, the two largest discharge orifices in the nozzle body must be positioned parallel to the
longest dimension of the hazard being protected.

The Models NV-P1 and NV-D/P2 must be located on branch T2A to nozzle only.
NOTE:
1. These limitations apply to PCI-70ABC using four NV -WA nozzles.
2. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length
from last tee to nozzle and the longest actual pipe length from last tee to nozzle does not exceed 10% of the longest
actual pipe length from last tee to nozzle. The number and type of fittings for all last tee to nozzle sections must be
equal.
3. A Main/Reserve Tee Check, Model TC-1, may be located between the cylinder and T1, and counts as two elbows in that
section.
4. All systems protecting vehicle paint spray booths require a tactory pre-set time delay.
5. When using an NV-P1 nozzle, the two largest discharge orifices in the nozzle body must be positioned parallel to the
longest dimension of the hazard being protected.

Detector Placement
Thermal detectors are required in all hazard areas protected
by the Pyro-Chem Vehicle Paint Spray Booth Industrial Fire
Suppression System if automatic system operation is
required. Either mechanical or electrical thermal detectors
can be used for automatic system operation. Mechanical
detectors (fusible links) are used in conjunction with the
Pyro-Chem Models MCH, NMCH, and EN-MCU control
devices. Electrical detectors are used in conjunction with the
Pyro-Chem Models ECH-24 and ECH-120 Control Heads.
A temperature survey must be performed to determine the
maximum ambient temperature of the hazard survey. The
detectors used to protect a hazard area must be at least
70OF above the maximum ambient temperature.
The minimum number of thermal detectors (either mechani-
cal or electrical) required for each hazard area is one detec-
tor for each twenty-five (25) pounds of agent required in that
hazard area. To determine the number of detectors required
in a particular hazard area, divide the total amount of agent
required for that hazard area by 25 and round up. Keep in
mind that at least one detector is required in every protected
hazard area.
Additional detectors may be used to achieve taster system
response: however, do not exceed the detector limitations
outlined in this manual.
For detector location, evenly divide the protected hazard
area into protected zones, with the number of protected
zones equal to the number of detectors. Located a detector
at the top center of each protected zone.
