2 INTRODUCTION
The Firetrace Indirect Low Pressure (ILP) FK-5-1-12 Clean Agent Automatic Fire Extinguisher Unit is UL Listed by Underwriters
Laboratories Inc, ULC Listed by Underwriters Laboratories of Canada, and approved with FM Approvals. These units are designed
for total flooding applications using FK-5-1-12 Clean Agent in accordance NFPA 2001: Standard on Clean Agent Fire Extinguishing
Systems.
The Firetrace Self-Contained Automatic Units have been tested to limits established by UL/ULC/FM in compliance with the
requirements specified in UL 2166 and FM 5600, and as detailed in this Manual.
Each installed Self-Contained unit is equipped with detection tubing, discharge piping, and nozzles. The Self-Contained concept
minimizes the amount of engineering involved in the units design. When the discharge piping and nozzles are installed within the
limitations stated in this manual no hydraulic calculations are required to determine pressure drop, agent flow, or discharge time.
The hazard being protected can be any size, shape, or volume provided that the hazard being protected is within the limitations
described in this Manual. Each extinguisher unit, when installed, is a self-contained unit, meaning that it is equipped with its own
automatic (non-electric) detection system, which when actuated, automatically releases the suppression agent into the hazard area.
Since the units are listed as automatic units (e.g. no simultaneous manual or electric actuation means is provided), only one (1)
extinguisher unit can be used to protect one hazard. These extinguisher units cannot be combined to protect a larger size hazard,
since they are not designed to provide for simultaneous actuation of (2) or more units.
Local authorities having jurisdiction should be consulted as to the acceptability for particular hazards and requirements covering
installation.
2.1 Fire Suppression Agent
The suppression agent used in Firetrace self-contained automatic indirect fire suppression systems is dodecafluoro-2-
methylpentan-3-one and can either be 3M™ Novec™ 1230 or FK-5-1-12 which has been reviewed & tested by Firetrace.

, is a colorless low odor fluid, low in toxicity, electrically
non-conductive, and leaves no residue. It is a clean and effective fire suppression agent that can be used on type A, B, and
C fires.
FK-5-1-12 is included in NFPA 2001 and has been evaluated and approved for use in occupied areas as a Total Flooding
agent, when used as specified under the U.S. Environmental Protection Agency (EPA) SNAP Program rules. Refer to the
SNAP Program rules for more information.
2.1.1 Cleanliness
FK-5-1-12 is clean and leaves no residue, thereby minimizing clean up after discharge along with keeping expensive
downtime to a minimum. Additionally, FK-5-1-12 is non-corrosive therefore sensitive electronics and materials such as
steel, aluminum, stainless steel, brass, plastics, and rubber are not affected by exposure to FK-5-1-12. This agent is also
environmentally friendly, having an ozone depletion potential (ODP) of 0.00 and an atmospheric lifetime of 5 days (the
closest halocarbon alternative is 33 years).
