1.7 Inspections & Tests
It is imperative that the system be inspected on a regular
basis. Refer to INSPECTIONS and TESTS recommended
in current Viking technical Data describing individual
components of the Viking Deluge System used.
The frequency of the inspections may vary due to
contaminated water supplies, corrosive or humid
atmospheres as well as the condition of the air supply to the
system. In addition to the instructions herewith, local
Authority Having Jurisdiction may have additional
maintenance, testing and inspection requirements which
must be followed.
Warning ! Any system maintenance which involves placing
a control valve or detection system out of service may
eliminate the fire protection capabilities of that system.
Prior to proceeding, notify all Authorities Having
Jurisdiction. Consideration should be given to employment
of a fire patrol in the affected areas.
1.7.1 Pneumatic Release System Low Air Pressure
Alarm Test:
Quarterly testing of low air alarms is recommended.
To test Pneumatic Release System "Low Supervisory
Air" Alarm:
1. To prevent operation of the Deluge Valve and filling the
system with water during the test, close the Main Water
Supply Control Valve (D1).
2. Fully open the releasing system Inspectors Test Valve
to simulate operation of a releasing device.
3. Verify that low air alarms operate within an acceptable
time period and continue without interruption.
4. Close the Inspectors Test Valve.
5. Close the Priming Valve (B1).
6. Establish recommended pneumatic supervisory
pressure to be maintained.
7. Alarms should stop.
8. Open the Priming Valve (B1).
When testing is complete, return the system to service
following steps 1 through 8 below.
CAUTION ! This procedure applies only when done in
conjunction with "Low Air" Alarm testing described above.
1. Verify that the pressure indicated on Priming Pressure
Water Gauge (B11) indicates that the priming chamber
is pressurized with System Water Supply Pressure
(B12).
2. Depress the plunger of Drip Check (B7). No water
should flow from the Drip Check when the plunger is
pushed.
3. Open Flow Test Valve (B6).
4. Partially open Main Water Supply Control Valve (D1).
5. When full flow develops from Flow Test Valve (B6),
close the Flow Test Valve.
6. Fully open and secure the Main Water Supply Control
Valve (D1).
7. Verify that the Alarm Test Valve (B5) and all other
valves are in their NORMAL operating position.
8. Depress the plunger of the Drip Check (B7). No water
should flow from the Drip Check when the plunger is
pushed.
1.7.2 Full Flow Trip test:
Performance of a Trip Test is recommended annually
during warm weather. Consider coordinating this test with
operation testing of the detectors.
CAUTION ! Performing this test will cause the Deluge Valve
to open. Water will flow into the sprinkler piping and from
any open sprinkler and/or nozzles unless the Optional
Shut-Off Valve is installed and closed prior to the test.
Take necessary precautions to prevent damage.
To test the operation of the hydraulically released
Deluge system:
1. Fully open the hydraulic release system Inspectors
Test Valve to simulate operation of a releasing device.
2. The Deluge Valve should open.
a. Water flow alarms should operate.
b. Water should fill the sprinkler piping and flow from
any open sprinklers and/or nozzles.
3. Close Inspectors Test Valve.
When testing is complete, return the system to service:
1. Close Water Supply Valve (D1).
2. Open System Main Drain Valve (D3).
3. Perform steps 1 through 10 of section 1.3 Placing the
system in service.
1.7.3 Drain Test:
A main drain test shall be conducted to determine whether
there has been a change in the condition of the water supply
piping and control valves.
Test procedure:
1. Record the pressure indicated by the supply water gauge.
2. Close the alarm control valve (if applicable)
3. Fully open the flow test valve.
4. Record residual pressure.
5. Close the flow test valve slowly.
6. Record the time taken for supply water pressure to return
to the original pressure.
7. Open the alarm control valve (if applicable)
