Argonite
®
Engineered Fire Suppression System
5-1 INTRODUCTION
The cylinders are installed in racks available in single, dual or quadruple row configuration.
An Argonite
®
system may consist of one or more cylinders, connected through a common
discharge manifold arrangement (cylinder bank).
The cylinders in the bank are connected to a common release manifold arrangement via
high pressure hoses and a check valve assembly, one for each cylinder. The check valves
allow removal of one or more cylinders from the manifold.
The cylinder valves are constructed to be capable of releasing of 80 Liters at 2900 PSI
(200 bar) within 1 minute.
The system can be released manually by removing a safety pin and turning the actuator
handle. The manual release unit is mounted on the side of the pilot cylinder valve.
Note: The green handle on the top of the cylinder valve is NOT for manual operation and
should not be used for the operation of the system.
The cylinders are provided with a pressure gauge assembly and the pilot cylinder is also
provided with a solenoid valve/manual release/gauge assembly.
When energized, the solenoid valve will provide pressure for opening all of the
cylinder valves.
The pressure from the pilot cylinder is fed to pneumatic actuators on the slave cylinders.
The manifold arrangement is further equipped with restrictor(s), which reduce the
discharge piping pressure during the discharge.
Selector valves may be used to divert Argonite to the required hazard.
From the restrictor, Argonite is fed through a piping system to the nozzles, which distributes
the gas in the room.
An Argonite system is to be monitored and controlled by the building fire alarm and
control panel or a local fire alarm and control panel (depending on local approval and/or
requirements). Fire detectors for each hazard shall be selected based on the flammables
involved, their burning rate and the accepted response time.
The room should be evacuated before discharge in order to secure both the extinguishing
effect as well as human safety (secure the hazard during and after the release). The
control panel may be equipped with a time delay of 10 to 30 seconds (depending on
requirements of authorities having jurisdiction). The warning alarm shall start sounding
simultaneously with the start of the time delay period.
