(SIMI). The integrated ball valve must be kept in closed position at all times when the cylinder is not in service. The system utilizes Firetrace flexible tubing that is attached to the top of the cylinder valve. This tubing is pressurised with nitrogen to maintain the cylinder valve in the closed position. -

Firetrace® FTILPINTHTBI Systems consist of the following major components: 1. Cylinder/Valve Assembly 2. Cylinder Mounting Bracket 3. Firetrace detection/actuating/discharge tubing and fittings 4. Discharge Nozzles 5. Pressure Switch (Optional) 6. Discharge piping and Fittings For a more comprehensive list of technical illustrations and part numbers, please see section 6. -
Page 6: System Design And Limitations
The normal operating pressure for Firetrace® Systems is 12bar at 20°C (174psig at 68°F). All Firetrace® systems are designed for an operating temperature range of -20°C to +60°C. Table 1 shows the cylinder gauge pressure-temperature relationship based on a charging pressure of 12bar at 20°C. -

Intermittent Temp: 40°C to 140°C (-40°F to 284°F) Firetrace Detection/Actuating/Discharge Tubing For the FTILPINTHTBI System, the Firetrace® tubing is used as a combination for heat detection, system activation and system discharge. The detection/actuation/discharge tubing is heat sensitive and in a fire situation is designed to rupture at any point along the tube upon direct flame impingement or at high temperatures associated with fire conditions. -

Where vertical positioning is not possible the system can be mounted within 45° of vertical. Firetrace Dry Powder Systems are not suitable for horizontal mounting 1. Securely mount the cylinder bracket to structural support using 4 or more mounting holes. -
Page 9: Discharge Piping And Nozzles
Discharge Piping and Nozzles 1. It is advised that a risk assessment is be carried out to determine appropriate discharge pipework and nozzle positioning. 2. Locate the nozzle(s) placement once a risk assessment has been carried out, ensuring design is within limitations and guidelines described in section 3. -
Page 10: Firetrace Detection/Actuation/Discharge Tubing
Firetrace® Detection/Actuation/Discharge Tubing The Firetrace® Automatic Detection tubing is the key part of the system and acts not only as the detector, actuator but also as the delivery method for a percentage of the ABC Powder. The correct installation of the tubing is important to achieve optimum performance from the system. The tubing must be mechanically protected outside the identified risk area and shall remain accessible to allow future servicing. - Page 11 The following models show both “Tyrap” and “P clip” methods of fixing all of which are acceptable: 8mm Firetrace Tubing shall be supported at maximum intervals of 200mm When the tubing is installed with a group of other cables/pipes it must be positioned on the underside of the loom...
