Step 2. Open the Inspector’s Test
Connection.
NOTE
Be prepared to quickly perform Steps
3, 4, and 5, if water must be prevented
from flowing beyond the riser.
Step 3. Verify that the DV-5 Valve has
tripped, as indicated by the flow of wa-
ter into the system.
Step 4. Close the Main Control Valve
(D).
Step 5. Close the Diaphragm Supply
Valve (P).
Step 6. Reset the DV-5 Deluge Valve
in accordance with the Valve Setting
Procedure.
Electric Actuation
Operation Test Procedure
Proper operation of the DV-5 Valve
(i.e., opening of the DV-5 Valve as dur-
ing a fire condition) must be verified as
follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps.
• Close the Stop Valve (B). Open the
Alarm Test Valve (G) and System
Drain Valve (E).
• Open the Stop Valve (B) one turn
beyond the position at which water
just begins to flow from the System
Drain Valve (E).
• Close the Alarm Test Valve (G) and
then close the System Drain Valve
(E).
Step 2. Test the deluge releasing panel
in accordance with the manufactur-
er’s instructions to energize the sole-
noid valve.
NOTE
Be prepared to quickly perform Steps
3, 4, and 5, if water must be prevented
from flowing beyond the riser.
Step 3. Verify that the DV-5 Valve has
tripped, as indicated by the flow of wa-
ter into the system.
Step 4. Close the system’s Main Con-
trol Valve (D).
Step 5. Close the Diaphragm Cham-
ber Supply Control Valve (P).
Step 6. Reset the DV-5 Deluge Valve
in accordance with the Valve Setting
Procedure.
Dry Pilot Actuator Test Procedure
For Dry Pilot Actuation
Proper operation of the Dry Pilot Ac-
tuator for dry pilot actuation must be
verified as follows:
Step 1. Close the Stop Valve (B).
Step 2. Open the Alarm Test Valve (G)
and the System Drain Valve (E).
Step 3. Open the Inspector’s Test
Connection on the Dry Pilot Line.
Step 4. Verify that the flow of water
from the Dry Pilot Actuator (R) drain
connection increases to a full flow.
Step 5. Verify that the Diaphragm
Chamber pressure has decreased
to below 25% of the water supply
pressure.
Step 6. Close the Inspector’s Test
Connection and allow the dry pilot line
pressure to re-establish. Check the
Dry Pilot Actuator (R) drain for leaks.
Any leaks must be corrected before
proceeding to the next step.
Step 7. Partially open the Stop Valve
(B). Close the Alarm Test Valve (G) as
soon as water discharges from the
System Drain Valve (E) and then close
the System Drain Valve (E) after water
ceases to drain. Observe the Automat-
ic Drain Valve (F) for leaks. If there are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-5 Valve is ready to be
placed in service and the Stop Valve
(B) must then be fully opened.
Low Pressure Alarm Test Proce-
dure And Condensate Drain Proce-
dure For Dry Pilot Actuation
For Dry Pilot Actuation, testing of the
Dry Pilot Low Pressure Switch (S) and
drainage of the pilot line condensate
must be performed as follows.
Step 1. Close the Stop Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P).
Step 3. Open the Alarm Test Valve (G)
and the System Drain Valve (E).
Step 4. Open the Inspector’s Test Con-
nection, and slowly relieve pneumatic
pressure. Verify that the Dry Pilot Low
Pressure Switch (S) is operational and
that the low pressure set points are as
follows:
• Low pressure alarm setting at ap-
proximately 0,4 bar below the mini-
mum pilot line service pressure re-
quirement shown in Graph B.
• Fire alarm setting at approximately
1,0 bar below the minimum pilot line
service pressure requirement shown
in Graph B.
Step 5. Close the Inspector’s Test
Connection and allow the Dry Pilot
Line to automatically repressurize.
Step 6. Individually open each low
point drain and then close after dis-
charge of any trapped condensate.
Step 7. Allow the Dry Pilot Line to au-
tomatically repressurize.
Step 8. Open the Diaphragm Supply
Valve (P).
Step 9. Partially open the Stop Valve
(B). Close the Alarm Test Valve (G) as
soon as water discharges from the
System Drain Valve (E) and then close
the System Drain Valve (E) after water
ceases to drain. Observe the Automat-
ic Drain Valve (F) for leaks. If there are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-5 Valve is ready to be
placed in service and the Stop Valve
(B) must then be fully opened.
Solenoid Valve Test Procedure
For Electric Actuation
Proper operation of the Solenoid Valve
for electric actuation must be verified
at as follows:
Step 1. Close the Stop Valve (B).
Step 2. Open the Alarm Test Valve (G)
and the System Drain Valve (E).
Step 3. Test the deluge releasing pan-
el in accordance with the manufactur-
er’s instructions to energize the sole-
noid valve.
Step 4. Verify that the flow of water
from the Solenoid Valve drain connec-
tion increases to a full flow.
Step 5. Verify that the Diaphragm
Chamber pressure has decreased
to below 25% of the water supply
pressure.
Step 6. Reset the electric detection
system in accordance with the manu-
facturer’s instructions to de-energize
the solenoid valve. Check the Solenoid
Valve drain for leaks. Any leaks must
be corrected before proceeding to the
next step.
Step 7. Partially open the Stop Valve
(B). Close the Alarm Test Valve (G) as
soon as water discharges from the
System Drain Valve (E) and then close
the System Drain Valve (E) after water
ceases to drain. Observe the Automat-
ic Drain Valve (F) for leaks. If there are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-5 Valve is ready to be
placed in service and the Stop Valve
(B) must then be fully opened.
