PCI -25150 INDUSTRIAL FIRE EXTINGUISHING SYSTEM
315- 120380 -4 DATED SEPTEMBER 1, 1987
A. DESCRIPTION
The Pyro Chem Model PCI - 15ABC is a pre- engineered dry chemical fire extinguishing system.
This system is charged with 12.5 pounds of mono ammonium phosphate based dry chemical,
Pyro Chem ##450- 020170. Vertical wall mounting for the PCI - 15ABC is provided by the Model
MB - 15 mounting bracket kit. It is Listed and Approved for use in total flooding applications
and for the protection of ventilation ducts. It is rated to protect Class "A ", "B" and "C"
hazards.
The Pyro Chem Model N - TF - ABC nozzle has been designed for ABC total flooding
applications, see Figure 2. This Model and the installation and operation limitations contained
in this supplement replace our existing Model N -TF nozzle for all ABC total flooding
applications.
The Pyro Chem Model N - ED nozzle has been designed for ventilation duct protection, see
Figure 2. This Model can be used with the Models PCI - 15BC and PCI - 15ABC systems.
The Pyro Chem Models PCI - 15BC and PCI - 15ABC can be used to protect up to 23 feet of
ventilation duct, with a maximum perimeter of 12 feet, over a straight run, using one (1)
Model N - ED nozzle.
The Pyro Chem Model PCI - 15ABC can support one (1) Model N - TF - ABC nozzle and protect a
cubic volume of 960 cubic feet, with a maximum area of 120 square feet.
The Pyro Chem Model PCI 25sABC can support one (1) Model N - TF - ABC nozzle and protect a
cubic volume of 1680 cubic,feet, with a maximum area of 168 square f eet. -
The Pyro Chem Model PCI 25sABC can support two (2) Model N - TF - ABC nozzles and protect
a cubic volume of 960 cubic feet, with a maximum area of 120 square feet, per nozzle.
The Pyro Chem Model PCI 50sABC can support two (2) Model N - TF - ABC nozzles and protect
a cubic volume of 1680 cubic feet, with a maximum area of 168 square feet, per nozzle.
The Pyro Chem Model PCI 50sABC can support four (4) Model N - TF - ABC nozzles and protect
a cubic volume of 960 cubic feet, with a maximum area of 120 square feet, per nozzle.
The Pyro Chem Model PCI - 25sBC can support one (1) Model N - TF nozzle and protect a cubic
volume of 1680 cubic feet, with a maximum area of 168 square feet.
The Pyro Chem Model PCI - 50sBC can support two (2) Model N - TF nozzles and protect a
cubic volume of 1680 cubic feet, with a maximum area of 168 square feet, per nozzle.
The Pyro Chem Models PCI - 15BC, PCI - 25sBC, and PCI - 50sBC are charged with regular
sodium bicarbonate based dry chemical, Pyro Chem #450- 020162.

Figure 1. Nozzles
The Model N -TF -ABC nozzle has been developed for use with the Pyro Chem Models
PCI- 15ABC, PCI- 25sABC, and PCI- 50sABC systems. It can be used for total flooding
applications.
The Model N -ED nozzle has been developed to protect ventilation ducts and can be
used with the Pyro Chem Models PCI -15BC and PCI -15ABC systems.
Application limitations for all discharge nozzles are described in the SYSTEM DESIGN
section of this supplement.

1.Total Flooding With ABC.
a. Cylinders:
The Models PCI- 15ABC, PCI- 25sABC and PCI- 50sABC cylinders can be used for ABC
total flooding applications.
• b. Nozzles:
The Model N -TF -ABC nozzle is used for all ABC total flooding applications.
The Model PCI -15ABC can support one (1) Model N -TF -ABC nozzle.
The Model PCI- 25sABC can support one (1) or two (2) Model N -TF -ABC nozzles.
The Model PCI- 50sABC can support two (2) or four (4) Model N -TF -ABC nozzles.
c. Temperature Range:
The operating temperature range for ABC total flooding applications is
1. 1 I -20 F. to 120 F. ( -28 C. to 48 C.).
