Nozzles
The Overlapping Female Nozzle(s) (p/n OL-F) are used for plenum, duct, overlapping appliance
protection, and dedicated appliance coverage (e.g., salamanders, upright broilers, chain broilers, and
appliance with upright obstructions). The nozzles include a cap (p/n 3074-1-1). The cap prevents
contamination from entering the pipe network and is designed to pop-off upon system discharge, allowing
the agent to flow to the protected hazard area. Refer to “Duct and Plenum Protection” on page 15.

Primary Actuator Kit (PAK)
The Primary Actuator Kit (PAK) (p/n 87-300030-001) is installed on each primary cylinder assembly to
pneumatically open the cylinder valve and provide actuation pressure for up to three secondary valve actu-
ators. A vent limiting orifice is present to allow easier resetting of SVA pistons during inspections.
The PAK consists of a pneumatic actuator, 24V DC solenoid valve, solenoid strainer (recommended by the
manufacturer), check valve, primary actuator hose, and associated fittings.
When activated, through automatic or manual system actuation, the control panel sends a momentary 24V
DC release signal. The solenoid strainer will filter out debris from entering the system. The PAK solenoid
will open, allowing pressure from the primary cylinder to pass through the solenoid and check valve. The
pressure flows into the primary actuator (actuating the primary cylinder), and into the interconnected sec-
ondary valve actuators (actuating the secondary cylinders).
The primary actuator has a 1/8” NPT inlet port for connection to the primary system cylinder, and a 1/8”
NPT outlet port for connection to the secondary cylinder actuation line or actuation line vent limiting orifice
for single cylinder system. The primary actuator includes a piston with a spring-loaded locking pin which
locks the piston in the discharge position, ensuring complete discharge of the cylinder contents. When
testing/inspecting, if a component fails inspection, replace the PAK assembly.

NOTE: The primary supervisory pressure switch is standard on primary tanks. Secondary
supervisory pressure switches are optional on secondary tanks.
