2-3 KIDDE IGS AGENT CYLINDERS AND RELEASE UNITS
The Agents are stored in high pressure cylinders having a filling pressure of 200 Bar (2900 PSI)
or 300 Bar (4351 PSI). The 80 Liter cylinders can be installed in single, double, and triple row
configurations.
Because the Agents are stored as a non-liquefied gas, dip tubes are not used, allowing the
cylinders to be installed either vertically or horizontally, as required. All rack configurations are
for vertical mounting only.
Note: Cylinders in a system must all be of the same size, pressure, and Agent.
2-3.1 Cylinder and Valve Assemblies
The Agent is stored in steel cylinders as a gas. The cylinder valve assembly is equipped with a
pressure gauge with a supervisory pressure switch connection for monitoring cylinder pressure
and a safety burst disc in compliance with DOT or TPED requirements.
Each cylinder valve assembly is fitted with an anti-recoil cap to prevent uncontrolled
discharge, in addition a safety transport cap, shroud or guard is provided to protect
cylinder valve during transportation or cylinder handling.
Each cylinder, manufactured in accordance with TPED and/or UN (DOT Recognized), ISO 9809-
2, is fitted with a pressure operated Kidde high pressure cylinder valve.
Standard cylinders are available in volumes of 80 liters filled with agent at pressures of 200
bar or 300 bar at a filling temperature of 15°C.
The cylinders are provided with the body painted red and green shoulder, with agency
markings where applicable.
Note: All cylinders are fitted with a valve protection device in accordance with the United Na-
tions ADR.
Figure 2-2 represents a typical cylinder assemblies. See Table 2-1 for cylinder dimensions.

WARNING
The safety cap must be installed on the discharge outlet whenever a charged
cylinder/valve assembly is not connected to the system piping. Failure to install
the safety cap could result in violent movement of the container in the event of
inadvertent actuation. Failure to follow these instructions could cause death,
personal injury and/or property damage.
