2-3.5 Actuation Hoses
The Actuation Hoses are used in multiple cylinder systems. Pressure is directed to the valve on
each agent cylinder using an actuation hose (see Figure 2-7, Figure 2-8, and Table 2-5). These
hoses include Quick Connect fitting for ease of installation and maintenance.
Note: During discharge, a continuous pressure of 8 bar is required in the actuation hose. This
pressure is supplied from the Agent cylinder.
