FIRETRACE FK-5-1-12 - Firetrace Detection Tubing (200005); Figure 3 - Cylinder Valves

800027-A 6 06/05/2023
The 940205 unit assembly is equipped with a small ILP valve (300112) containing two 1/4 in NPT discharge ports. The 940555, 941055 and 942055
unit assemblies are equipped with a medium ILP valve (302118) containing two 1/2 in NPT discharge ports.
NOTE: The ball valve must be kept closed at all times when the cylinder is not in service.
Each valve is also equipped with (2) discharge outlet ports. Each outlet port is provided with a safety plug that must be installed in the discharge outlet
whenever a system is not in service. These plugs are safety devices designed to prevent uncontrolled discharge of the system in the event that the
valve is accidentally actuated.
WARNING
The safety plugs must be installed in the valve discharge outlets at all times, except when connected into the units
discharge tubing. Failure to follow these instructions could result in property damage, personal injury, or death.
NOTE: All Firetrace FK-5-1-12 ILP Units utilize a straight siphon tube. All Firetrace FK-5-1-12 ILP Units are to be installed only in a vertical (valve on top)
position.

3.3 Firetrace Detection Tubing (200005)
The Firetrace Detection Tubing (FDT) is a UL recognized component per UL standard 521 (See Certificate of Compliance 20140705-S35465). The
FDT is a linear, pneumatic fire detection device that responds to a combination of the heat and radiant energy from a fire. It is installed throughout the
hazard volume with one end connected to the top of the cylinder valve, then pressurized with nitrogen to 195 psig.
The detection tubing is heat sensitive and, in a fire, situation is designed to rupture at any point along its length upon direct flame impingement or when
the temperature reaches 383°F (195°C). The rupture of the tube releases the nitrogen pressure causing the cylinder valve to actuate, resulting in
complete discharge of the FK-5-1-12 agent through the discharge network and ultimately from the discharge nozzles throughout the protected
enclosure.
