TRIM COMPONENTS Trim components are required to operate the clean agent cylinder(s). 1/2" (15 mm) NPS Female \ Conduit Hub Knurled with 40" (1016 mm) leads Swivel Nut Emergency Release Button Electric Valve Actuator w/ Supervisory Limit Switch' (P/N 20722) The electric valve actuator attaches to the primary cylinder at the valve actuation connection and is utilized to automati- cally open the cylinder valve upon receipt of a signal from the control panel or other source. It operates between 17 and 30 VDC and consumes 500 mA (.5 Amps) at 24 VDC nominal with a maximum supervisory current of 30 mA (0.03 Amps). The electric valve actuator body is steel construction with a brass knurled swivel nut and a stainless steel actuation pin that depresses the valve core when energized. The limit switch contacts are normally closed when the actuator is not installed onto the cylinder valve and open when the actuator is fully installed onto the valve actuation connection at the top of the cylinder valve. Manual Valve Actuator (P/N 17001) An optional manual valve actuator attaches to the top of the electric valve actuator and provides a means to manually open the cylinder valve. The manual valve actuator consists of a brass body, stainless steel actuation pin, and steel safety ring pin. To discharge the primary cylinder manually, the ring pin is re- moved and the emergency release button is depressed forc- ing the pin in the electric valve actuator to depress the valve core of the cylinder valve. All other connected cylinders will be opened pneumatically. MULTI -CYLINDER ARRANGEMENT COMPONENTS Up to 16 cylinders (1 primary and 15 secondary) may be installed in a single arrangement, with a maximum length of 100 ft (30.48 m) of pilot actuation hose or tubing extending from the primary cyl- inder in either direction. Atypical arrangement is shown below.
