Argonite
®
Engineered Fire Suppression System
38-KFSARG-000
4-4 RESTRICTOR
The purpose of the restrictor is to reduce the pressure of the gas from the cylinder before it enters
the piping system. The pressure is reduced from the storage pressure of 2900 PSI (200 bar).
Note: The Kidde Fire Systems Argonite flow calculation software is required to determine
restrictor orifice sizes and pressure up and down stream of the restrictor.
4-5 RELEASE MODES
The system is capable of electric, pneumatic and manual actuation and can be released by one
or more of the following methods.
4-5.1 Automatic Release
When a fire condition is detected and the control panel goes into an alarm state, the
panel will annunciate a visual and/or audible alarm, activate the alarm relay and energize
the high-pressure solenoid valve on the pilot cylinder. In a selector valve system, the
low-pressure solenoid valve at the selector valve is also energized.
4-5.2 Manual Remote Release, Electrical
Remote release is accomplished by actuation of a switch at a manual release station (if
required). Once the station has been actuated, the alarm and control panel will operate
the system as described above.
4-5.3 Manual Emergency Release
In the unlikely event of total power failure and expiration of the emergency batteries, the
system may be activated by pulling the pin and rotating the actuator handle. In a selector
valve system, the manual override on the selector valve for the desired area must also
be operated.
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.
4-6 CYLINDERS
Each cylinder is fitted with a pressure operated Argonite cylinder valve. The cylinders are available
in 15.9, 66.7 or 80 Liter capacity and filled with Argonite at a pressure of 2900 PSI (200 bar) at 70°F
(21.1°C). The cylinders are provided with a protective cap and green shoulder markings.
4-6.1 Cylinder Valves
Each valve is to be provided with a pneumatic operator to open the valve; one of the
cylinder valves in the bank must be fitted with a manual/pneumatic actuator. A pressure
gauge with supervisory pressure switch is provided for local and/or remote monitoring of
cylinder pressure.
The pilot cylinder in a bank is provided with a pressure gauge/solenoid valve actuator
unit allowing for electrical release. In event of release by the use of pressure through the
manual/ pneumatic actuators on the slave cylinders, the pilot cylinder will provide pressure
for their opening. The interconnection between pilot and slave cylinders is accomplished
using high pressure flexible hoses.
After a discharge, the cylinder valve will automatically close when the pressure decreases
to approximately 45 PSI (3 bar), maintaining a positive pressure as well as preventing
moisture from entering the cylinder and thus ensuring corrosion protection of the interior
of the cylinder.
