8-6 TESTING
8-6.1 Solenoid Valve, High Pressure
The operation of the solenoid valve unit on the Argonite cylinder shall be verified as
follows:
1. Mechanically disconnect the pressure gauge solenoid valve unit from the Argonite
cylinder valve.
2. Connect a pressure supply to the inlet of the unit.
3. Energize the solenoid valve (24 Vdc 13 w).
4. Confirm operation.
5. Reinstall the pressure gauge solenoid valve unit. (Remember to install a new O-ring).
Before connecting the hose to the pneumatic actuator, ensure that there is no leakage
from the hose end.
8-6.2 Pneumatically Operated Selector Valves
Check the operation of the pneumatically operated selector valves as follows:
1. Disconnect the instrument tubing from the pneumatic actuator on the selector valve.
2. Apply a pressure of 85 to 125 PSI (6 to 8 bar) to the inlet port of the actuator.
3. Supply 24 Vdc to the actuator solenoid; the valve should open.
4. Remove the 24 Vdc power; the valve should close.
5. Remove the pressure from the actuator.
6. Close the valve using the handle on top of the valve. (The valve will not
close automatically.)
7. The handle can also be used to open the valve during emergency conditions.
8-6.3 Pressure Regulator, Selector Valve Systems
Check the operation of the pressure regulator. If no full discharge test is performed, the
operation/adjustment of the pressure regulator can be performed as follows:
1. Remove the regulator and install it in a test bench consisting of a pressure source of
2900 PSI (200 bar), a calibrated pressure gauge 0 to 4000 PSI (0 to 300 bar) upstream,
and a calibrated pressure gauge 0 to 300 PSI (0 to 20 bar) downstream of the
reducing valve.
2. Correct operation of the regulator will be indicated on the downstream pressure gauge,
which should read approximately 85 to 125 PSI (6 to 8 bar). The relief valve will open
if the regulator outlet pressure exceeds 145 PSI (10 bar).
3. If pressure is out of range, remove the cover and adjust by turning the internal screw
clockwise to increase the pressure and counterclockwise to decrease the pressure
until the required settings are achieved.
No further dismantling of the regulator shall be done. Should the regulator be faulty,
return to Kidde Fire Systems for factory repair or replacement.
