3.Close the Alarm Test Valve. All local
alarms should stop sounding and
pressure switch is reset.
4.Verify that the supply piping to the
alarm drains properly .
Deluge Trim Testing
A
semi-annual
Deluge Trim Testing
is recommended. Testing of the control
trim is conducted with no flow of water
to the system.
1. Open the Flow Test Valve to flush
away debris or foreign particles
which may have accumulated in the
Inbal
Deluge Valve inlet.
2. Close the Flow Test Valve.
3. Close the Water Supply Valve
installed in the inlet of the
Inbal
Deluge Valve.
4. Open the inspector's test valve in the
hydraulic release system. Water
should be drained from the deluge
trim. Verify that the pressure reading
on the System Pressure Gauge drops
to zero which simulates an open
position of the
Inbal
Deluge Valve.
5.Reset the valve by performing the
instructions in Resetting.
Trip Testing
An
annual
Trip Testing is recommended.
Performing the Trip Testing will cause
water to flow from all open sprinklers
and/or nozzles. Prevent damage by
taking necessary precautions.
1. Open the Flow Test Valve to flush
away any debris or foreign particles
which may have accumulated in the
Inbal
Deluge Valve inlet.
2.Close the Flow Test Valve.
3. Trip the
Inbal
Valve to open by either:
a) Opening the inspector’s test valve.
b) Opening the Emergency Release
Valve.
The water in the
Inbal
Valve Control
Chamber is released to the atmos-
phere. The
Inbal
Deluge Valve will
open wide and water will flow to the
system. All the water flow alarms
should operate. Verify that the whole
system is working properly.
4. Close the inspector's test valve or the
Emergency Release Valve.
5. Reset the valve by performing the
instructions in Resetting.
Removal
To remove the
Inbal
Deluge Valve:
1.Close all the pressure supplies:
a) Water Supply Valve.
b) Trim Shutoff Valve.
2. Open the Emergency Release Valve to
release the water pressure from the
Inbal
Valve Control Chamber.
3.Open the Flow Test Valve and Drain
Valve to allow all the water to drain.
4. Disconnect th e union and remove the
trim from the valve.
5. Remove the
Inbal
Valve from the line
for inspection.
6. To reinstall, follow the Installation
procedure (use new gaskets for
flanged or wafer valve).
Inquiries/Orders
The Data Sheet For Inquiries/Orders
(bulletin F01-05-01) should be
submitted.

3.Verify that the Trim Shutoff Valve,
Alarm Test Valve, Emergency Release
Valve, Pressure Gauge Valves, Flow
Test Valve, and Drain Valve are in set
position.
4.The Supply and System Pressure
Gauges should be checked for
accuracy.
5.Visually inspect for broken or
missing parts, or other evidence
of impaired protection.
