• Cylinder Mounting Bracket
• Firetrace Detection Tubing (FDT) & Fittings (No Substitute)
• Discharge Nozzle(s)
• Discharge Network & Fittings
• Pressure Switch (Optional)
Once installed, the Firetrace Pre-Engineered Automatic Indirect Low Pressure (ILP) Clean Agent Extinguisher System becomes a self-
contained, self-actuating unit that does not require an external power source.
The unit utilizes a UL recognized (per UL Standard 521) linear heat detector (see Certificate of Compliance 20140705-S35465) known
as Firetrace Detection Tubing (FDT). This tubing is pressurized with dry nitrogen, is temperature sensitive, and acts as a continuous
linear thermal detector that ruptures upon direct flame impingement or at temperatures above 383 °F [195 °C].
Once the detection tubing is ruptured, the valve automatically opens, allowing the FK-5-1-12 agent to flow through the discharge piping,
distributing the extinguishing agent through the nozzle(s) into the protected volume.
Upon actuation, the pressure switch can be used to indicate discharge, shutdown ventilation, close all openings, shut-off electrical power,
etc. as may be required.

3.2 FK-5-1-12 Cylinders (100300, 100600, 101200, 120020)
FK-5-1-12 is stored in steel cylinders pressurized with nitrogen to 195 psig at 70°F (13.4 bar at 21°C). Table 3-1 describes the 2.5, 5, 10 and 20 Lb
system assemblies. Each cylinder is equipped with a straight siphon tube and can only be mounted in a vertical (upright) position (±30°).
