PRELIMINARY INSPECTION BEFORE
PLACING THE SYSTEM IN SERVICE
1. Open door to mechanical section. Main Water Supply
Control Valve (D1) should be CLOSED. Priming
valve (B1) must be CLOSED. Flow Test Valve (B6)
and main drain valve (D3) must be CLOSED. Alarm
test valve (B5) must be CLOSED. All gauges (B11,
B12 and E3) should show 0 psi pressure.
2. Connect all detection and alarm audible devices
according to electrical schematics (see TBA field wiring
diagram in PROGRAMMING SECTION).
3. Connect the AC power for the control panel (L1) on a
separate breaker in the electric distribution panel (see
TBB field wiring diagram in PROGRAMMING
SECTION).
Note: Do not use these circuit breakers for other parallel
applications. If necessary, equip each circuit breaker with
a security seal in order to avoid accidental closing.
4. After the Flow Control Valve is set, operation of the
valve requires the release of priming water from the
priming chamber. This may be by automatic or manual
operation of one of the release systems described
above. For specific trim arrangement, refer to the
MECHANICAL TRIM DESCRIPTION.
Note: Electric Release: Solenoid valves, system control
panels and electrical detectors must be compatible.
Consult the CONTROLS SECTION for compatibility charts.
PLACING THE SYSTEM IN SERVICE:
(Refer to mechanical trim description and TRIM
SCHEMATIC)
1. Verify the following:
a) The system Main Water Supply Control Valve (D1) is
CLOSED.
b) The system has been properly drained.
c) Flow Test Valve (B6) is OPEN.
d) The Emergency Release Valve (B10) is CLOSED.
e) The system water supply piping is pressurized up to
the CLOSED Main Water Supply Valve (D1) and the
priming line is pressurized up to the CLOSED
Priming Valve (B1).
2. Verify that all releasing devices are set and that any
Inspector's test Valve and/or auxiliary drain valves are
CLOSED.
a) OPEN Priming Valve (B1).
3. OPEN Flow Test Valve (B6).
4. PARTIALLY OPEN Main Water Supply Control Valve
(D1).
5. When full flow develops from the Flow Test Valve (B6),
CLOSE the Flow Test Valve.
a) Verify that there is no flow from the open Flow Test
Valve (B6).
6. CLOSE Flow Test Valve (B6).
7. FULLY OPEN and secure the Main Water Supply
Control Valve (D1).
8. Verify that the Alarm Test Valve (B5) is CLOSED and
that all other valves are in their "normal" operating
position (Refer to TRIM SCHEMATIC for details).
9. Depress the plunger of the Drip Check Valve (B7). No
water should flow from the Drip Check when the plunger
is pushed.
10. Check and repair any leaks.
11. On new installations, systems that have been placed out
of service, or where new equipment has been installed,
trip test system to verify that all equipment functions
properly. Refer to MAINTENANCE – ANNUALLY for
instructions.
CAUTION ! Performing a trip test results in operation of the
Deluge/Flow Control Valve. Water will flow into the sprinkler
piping. Take necessary precautions to prevent damage.
12. After completing the trip test, perform MAINTENANCE –
SEMI-ANNUALLY.
Note: When a valve has been removed from service and is
subject to freezing or will be out of service for an extended
period of time, all water must be removed from the priming
chamber, trim piping, water supply piping and any other
trapped areas.
13. Notify the Authority Having Jurisdiction, remote station
alarm monitors, and those in the affected area that the
system is in service.
MECHANICAL TRIM SECTION
1. System Operation
In the SET condition:
System water supply pressure enters the priming chamber
of the Flow Control Valve (A2) through the priming line
which includes a normally open priming valve (B1), strainer
(B2), restricted orifice (B3) and spring loaded check valve
(B4).
System water supply pressure enters the priming chamber
of the Flow Control Valve. In the SET condition, water
supply pressure is trapped in the priming chamber by a
spring loaded check valve (B4) and normally closed
Solenoid valve (F2). The pressure in the priming chamber
holds the Flow Control Valve clapper closed, keeping the
outlet chamber and system piping dry.
In a fire condition:
When the detection condition is satisfied, system Control
Panel activates an alarm and energizes normally closed
Solenoid valve (F2) open and normally open solenoid
valve (F1) closed.
Pressure is released from the priming chamber of the Flow
Control Valve (A2) to the open drain manifold faster than it
is supplied through the restricted orifice (B3). The Flow
Control Valve clapper opens to allow water to flow into the
system piping and alarm devices, causing the optional
Water Motor Alarm (C2) and water flow alarms connected
to the Alarm Pressure Switch (C1) to activate.
When the Flow Control valve operates, the PORV (B14) is
pressurized, causing it to latch open.
