6.1 Dry-pipe Vacuum Sprinkler System
Note: Numbers indicated between brackets refer to items
on the TRIM SCHEMATICS from section B MECHANICAL and
section D VACUUM SUPPLY.
The vacuum sprinklers piping network is under vacuum
pressure. This dry-pipe vacuum sprinkler system utilizes a
Viking deluge valve (A1) which opens by the operation of
the solenoid valve (F1) or the manual emergency release
valve (B10).
The vacuum level inside the piping network is supervised
by the FLX-PC® VACUUM / PRESSURE CONTROLLER for low,
high and alarm vacuum levels. One objective of this
device is to perform the opening of the deluge valve in less
than 5 seconds following the opening of a vacuum
sprinkler, thereby permitting a more rapid fire attack.
The electric release system operates by the alarm
pressure of the FLX-PC® VACUUM / PRESSURE CONTROLLER.
If a vacuum sprinkler is fused, or damage to a vacuum
sprinkler or to piping network occurs, the FLX-PC® will
operate and the deluge valve (A1) will open, flowing water.
The electric release system also operates when a manual
pull station is triggered, opening the deluge valve (A1).
Water will be contained in the piping network until the
opening of a vacuum sprinkler.
In the event of no operation of the electric release system
or if the release control panel is no more powered from AC
power and batteries, the dry-pipe vacuum sprinkler system
can be manually trip by triggering the manual emergency
release valve (B10), causing the deluge valve (A1) to
open. Water will be contained in the piping network until
the opening of a vacuum sprinkler.
7- System release
7.1 Electric release
Electric release trim for dry-pipe vacuum sprinkler system
utilizes an electric solenoid valve (F1) controlled by the
approved release control panel provided with this system
(see section E CONTROLS and VFR-400 manual for
details).
In fire condition, when a vacuum sprinkler is fused, or
damage to a vacuum sprinkler or to piping network occurs,
an alarm pressure signal from the FLX-PC® VACUUM /
PRESSURE CONTROLLER to the release control panel
energizes the solenoid valve (F1), causing the deluge
valve (A1) to open. Water will flow from the previous
opening.
When a manual pull station is triggered, the release control
panel energizes the solenoid valve (F1), causing the
deluge valve (A1) to open. Water will be contained in the
piping network until the opening of a vacuum sprinkler.

1.4 System Operation
1.4.1 In the SET condition
System water supply pressure enters the priming chamber
of the deluge valve (A1) through the priming line which
includes a normally open priming valve (B1), strainer (B2),
restricted orifice (B3) and spring loaded check valve (B4).
Water supply pressure is trapped in the priming chamber
of the deluge valve (A1) by spring loaded check
valve (B4), normally closed solenoid valve (F1), manual
emergency release valve (B10) and PORV (B9)
(pressure operated relied valve). The pressure in the
priming chamber holds the deluge valve clapper closed,
keeping the outlet chamber and vacuum sprinklers piping
dry.
1.4.2 In a fire condition
When the FLX-PC®alarm condition is satisfied, the
release control panel activates an alarm and energizes the
normally closed solenoid valve (F1) to open.
Pressure from the priming chamber of the deluge
valve (A1) is released to the open drain manifold faster
than it is supplied through the restricted orifice (B3). The
deluge valve clapper opens to allow water to flow into the
piping network and alarm devices, causing water flow
alarms connected to the alarm pressure switch (C1) and
the optional water motor alarm (C2) to activate. When a
vacuum sprinkler head opens, water will flow from the
vacuum sprinklers piping network.
When the deluge valve (A1) operates, the sensing end of
the PORV (B9) (pressure operated relief valve) is
pressurized, causing it to open, draining the priming
chamber, preventing the deluge valve from resetting, even
if the open releasing devices close. The vacuum pump will
be automatically disabled. The deluge valve can only be
reset after the system is taken out of service, and the
outlet chamber of the deluge valve and associated trim
piping is depressurized and drained.
1.4.3 Manual operation
Anytime the handle of the manual emergency release
valve (B10) is triggered, pressure is released from the
priming chamber of the deluge valve (A1) causing deluge
valve to open. Alarm devices (C1 and C2) will operate.
When a vacuum sprinkler opens, water will flow through
the piping network.
1.4.4 Vacuum loss condition
If a vacuum sprinkler opens or any time vacuum is lost in
piping network, the FLX-PC® (G18) will display LOW
PRESSURE followed by ALARM PRESSURE, and the release
control panel will receive supervisory and alarm signals.
Pressure is then released from the priming chamber of the
deluge valve (A1) causing deluge valve to open. Alarm
devices (C1 and C2) will operate.When a vacuum
sprinkler opens, water will flow through the piping network.
1.5 Emergency instructions
To take system out of service
WARNING ! Placing a control valve or detection system out
of service may eliminate the fire protection capabilities of
the system. Prior to proceeding, notify all local
AUTHORITIES HAVING JURISDICTION. Consideration should
be given to employ a fire patrol in the affected areas.

1.8 Maintenance
NOTICE:The owner is responsible for maintaining the fire
protection system and devices in proper operating
condition.
The system shall be maintained in full operation condition
at all times.
All troubles or impairments shall be corrected promptly
consistent with the hazard being protected.
Refer to MAINTENANCE INSTRUCTIONS provided in Viking
Technical Data describing individual components of the
system used.
The vacuum pump system shall be maintained in full
operating condition at all times (refer to section D
VACUUM SUPPLY).
Refer to NFPA-25 for a full description of maintenance.
1.8.1 FLX-PC®vacuum pump monitoring
The monitoring of the vacuum pump operation time is
useful because it notified you about a minor leak in the
piping system. If there is a leak in the piping system, the
pump will operate much more than it would normally do.
Moreover, the operating time will change if there is water
in the piping system (the system must be properly
drained).
To access the vacuum pump operation time, press and
hold the push-button of the FLX-PC®(G18)unit for
3 seconds then release the push-button.
***VER: 1.0.0***
1000:45:33 HRS
The second line shows the total operating time of the
vacuum pump.
The display will automatically return to its normal condition
after 10 seconds of inactivity of the push-button.
For more information, refer to FLX-PC®VACUUM /
PRESSURE CONTROLLER at section E ELECTRICAL.
Records
Records of inspections, tests and maintenance of the
system and its components shall be made available to the
AUTHORITY HAVING JURISDICTION upon request. Typical
records include, but are not limited to: valves inspection;
flow, drain, and pump tests, and trip test of the deluge
valves.
Acceptance test records should be retained for the life of
the system or its special components. Subsequent test
records should be retained for a period of one (1) year
after the next test. The comparison determines
deterioration of system performance or condition and the
need for further testing or maintenance.
Monthly
1. Inspection of gauges (water supply and system
pressure) to ensure good condition and normal water
supply pressure.
2. Control valve shall be externally inspected. The valve
inspection shall verify the following:
a) The gauges indicate that normal supply water
pressure is being maintained.
b) The valve is free of physical damage.
c) All valves are in the appropriate open or closed
position.
d) There is no leakage from the alarm drains.

figures 1 and 2 SIMPLIFIED and DETAILED SYSTEM TRIM
SCHEMATICS from this section and section D VACUUM
SUPPLY.
2.1 Description
The FIREFLEX®VACTEC®system with the dry-pipe vacuum
sprinkler trim utilizes a Viking deluge valve (A1) to control
water flow into piping network equipped with closed
vacuum sprinklers. Under normal operating conditions,
the piping network is supervised with vacuum to ensure
against undetected leaks.
Electric release system requires an electrically operated
solenoid valve (F1) controlled by an approved release
control panel.
If a vacuum sprinkler is fused, or damage to a vacuum
sprinkler or to piping network occurs, a low pressure
supervisory signal from the FLX-PC®(G18) VACUUM /
PRESSURE CONTROLLER will be sent to the release control
panel followed by an alarm pressure signal.
Dry-pipe vacuum sprinkler system is designed so the
deluge valve (A1) will open by the operation of the
solenoid valve (F1) when the FLX-PC®(G18) alarm
pressure signal operates, or when a manual pull station is
triggered. When the deluge valve (A1) opens, water will
flow into the piping network and out of any open vacuum
sprinklers or any opening on the piping network.
Note: The FIREFLEX®VACTEC®trim is provided with a
contractor's hydrostatic test water supply port handily
located on the priming trim. Simply remove the plug of the
connection and connect the test pump between this port
and the system side port located on the riser trim. Refer to
figure 2 DETAILED SYSTEM TRIM SCHEMATIC of this section
for exact location of these connections.

1- Vacuum supply
Note: Numbers indicated between brackets refer to items
on the TRIM SCHEMATICS from this section and section B
MECHANICAL.
Vacuum sprinkler system uses negative vacuum pressure to
supervise the piping network. The vacuum supply is
provided within the FIREFLEX®VACTEC® unit. The vacuum
supply trim is factory assembled in the system cabinet,
calibrated and pressure tested.
The vacuum supply system trim includes a liquid ring
vacuum pump (G1), all regulating devices to control flow of
water and pump motor shut off electrical components.
The vacuum pump (G1) power requirement is specified at
220/240VAC, 50/60Hz, 1.5HP, 1phase.
The vacuum pump (G1) is able to establish the total required
vacuum pressure in 30 minutes for system capacity up to
4000 gallons.
1.1 Operation
The start and stop adjustments of the vacuum pump (G1)
are factory set and require no further adjustments. The
pump motor is controlled by a contactor (G17) which is
activated on and off by the FLX-PC® (G18) VACUUM /
PRESSURE CONTROLLER.
The liquid ring of the vacuum pump (G1) is generated by a
water line composed by a water ring control valve (G13), a
solenoid valve (G2), a pre-regulator (G3), a fine-adjust
regulator (G4) and a restricted orifice (G5). A float check
valve (G6) and a reversed check valve (G11) prevent flood
through possible water coming from drain collector.
Vacuum is sucked from the piping network through the
2-way check valve (G7). This check valve allows vacuum to
be sucked, but will prevent water to enter the vacuum
pump (G1) when deluge valve (A1) is opened.
When the piping network has been drained after operation,
the remaining water inside the deluge valve (A1) will be
drained out by the operation of the vacuum pump (G1).
To apply vacuum supply:
Switch ON the vacuum pump (G1) On/Off switch (G16).
To close vacuum supply:
Switch OFF the vacuum pump (G1) On/Off switch (G16).
1.2 Pressure settings
All pressure settings are factory set and do not need further
calibration unless malfunction.
a) FLX-PC® (G18) set to -140 mBAR (-14 kPa) for LOW
PRESSURE supervisory condition.
b) FLX-PC® (G18) set to -220 mBAR (-22 kPa) for HIGH
PRESSURE supervisory condition.
c) FLX-PC® (G18) set to -130 mBAR (-13 kPa) for ALARM
PRESSURE condition.
d) FLX-PC® (G18) set to -150 mBAR (-15 kPa) for vacuum
pump (G1) start.
e) FLX-PC® (G18) set to -180 mBAR (-18 kPa) for vacuum
pump (G1) stop.
f) Pre-regulator (G3) set to 50 PSI (344 kPa) via pre-
regulator pressure gauge (G14).
g) Fine-adjust regulator (G4) set to 10 PSI (69 kPa) via
fine-adjust regulator pressure gauge (G15).
h) Vacuum breaker valve (G9) set to -300 mBAR (-30 kPa)
i) Vacuum breaker valve (G12) set to -200 mBAR (-20 kPa)
1.3 Maintenance and inspection
If the vacuum pump (G1) is hard to start, too much water
could be present in the deluge valve (A1) system. To fix this
problem, close vacuum system and open system drain
valve (G10) until all water has been drained out. Close the
system drain valve and apply vacuum supply.
If the vacuum pump (G1) doesn't start at all, contactor (G17)
may have tripped. Open the junction box cover of the
vacuum pump controller and reset the contactor (refer to
section E CONTROLS). Reinstall the junction box cover.
The FLX-PC® (G18) VACUUM / PRESSURE CONTROLLER is
equipped with an hour counter which reveals the operating
time of the vacuum pump (G1). During regular maintenance,
verify the counter to see if the vacuum pump (G1) is
activated often. If so, this could point to an excessive leak in
the piping network.
The vacuum pump (G1) is fitted with "sealed for life" bearing
and should provide maintenance free life.
The vacuum pump (G1) is fitted with single acting
mechanical seals. These seals should be replaced when
worn, scratch or cracked. Replacement is also necessary
when rotating portion of the seal does not firmly grip the
shaft.
If the vacuum pump (G1) is to be out of service for extended
period of time, it should be internally protected from rusting
by using a suitable water soluble rust inhibitor, available from
Busch GVT. This will give protection for up to twelve (12)
months. Rotate the pump by hand to coat the interior of the
pump surfaces with the fluid. The pump should be revolved
periodically to prevent bearing indentation.
