SERIES776LOW-PRESSUREACTUATOR
The Series 776 Low-Pressure Actuator is located in the trim of Series
764 FireLock NXT Alternate Wet/Dry Valves and acts as the trigger for
the system when it is set in the dry configuration.
Diaphragms separate the low-pressure actuator into three chambers.
The upper air chamber controls activation, while the middle and lower
chambers act as the water valve.
During setup, system air is applied to the upper chamber of the low-
pressure actuator. When the Auto Vent Sleeve of the low-pressure
actuator is pulled up, the upper chamber manually sets. Air pressure in
the upper chamber holds the Auto Vent closed, while it exerts force on
the water seal of the middle chamber.
When the diaphragm charge line is opened, water enters the lower
chamber of the low-pressure actuator. Water that enters the low-pres-
sure actuator flows to the middle chamber through the inlet eyelet,
which is pressurized by system air pressure in the upper chamber.
Since the area of the lower diaphragm (exposed to water pressure in
the middle chamber) is greater than the area of the lower chamber, the
lower chamber seals off. Water does not flow to the outlet of the low-
pressure actuator, and the supply water pressure creates the water seal.
When system air pressure decays to 0.5 Bar/48 kPa/7 psi, the force
exerted by the compression spring in the Auto Vent is greater than the
force exerted by air in the upper chamber. The Auto Vent opens, and all
air pressure in the upper chamber evacuates.
The upper diaphragm releases water pressure in the middle chamber
of the low-pressure actuator, which allows the lower diaphragm to lift
and water to flow from the inlet to the outlet. This flow of water releases
pressure from the diaphragm charge line of the Series 764 FireLock
NXT Alternate Wet/Dry Valve, thus allowing the diaphragm to retract.
The clapper opens, and water flows into the sprinkler system.

SERIES746-LPADRYACCELERATOR
The Series 746-LPA Dry Accelerator is a quick-opening device, which
exhausts air from the Series 776 Low-Pressure Actuator to speed valve
operation.
A diaphragm separates the Series 746-LPA Dry Accelerator into two
chambers. The closing chamber contains a compression spring, which
maintains the chamber in the closed position. The closed position is
maintained as long as the pressure differential between the opening and
closing chambers is less than 0.2 Bar/21 kPa/3 psi.
When the system introduces air pressure into the dry accelerator, air
enters the closing chamber and passes through a check valve to the
opening chamber. The check valve, which allows flow into the open-
ing chamber, prevents pressure from escaping the opening chamber.
Therefore, air can escape only through the restrictor.
When a rapid loss of system air pressure occurs, such as an open
sprinkler, air escapes from the closing chamber faster than it escapes
from the opening chamber. As the sprinkler system’s pressure continues
to decay, a differential pressure develops across the diaphragm. When
this differential pressure reaches 0.2 – 0.3 Bar/21 – 34 kPa/3 – 5 psi,
the opening chamber’s pressure overcomes the compression spring’s
closing force, causing the closing chamber to open to the atmosphere.
The closing chamber opens immediately and releases pressure from the
actuator, resulting in valve operation.

AIRSUPPLYREQUIREMENTS
The required air pressure for Series 764 FireLock NXT Alternate Wet/
Dry Valves is 0.9 Bar/90 kPa/13 psi minimum, regardless of the system
supply pressure. Normal air pressure should not exceed 1.2 Bar/
124 kPa/18psi. Failure to maintain air pressure within the 0.9 Bar/
90 kPa/13psi to 1.2 Bar/124 kPa/18psi range could delay system
operation response time.
Systems with air pressure higher than 1.2 Bar/124 kPa/18 psi may
require the addition of a Series 746-LPA Dry Accelerator. NOTE: The
Series 746-LPA Dry Accelerator must be used only on systems operat-
ing below 2.1 Bar/207 kPa/30 psi of air. If air pressure higher than
2.1 Bar/207 kPa/30 psi is required, the Series 746 Dry Accelerator
should be used.
If multiple Series 764 FireLock NXT Alternate Wet/Dry Valves are
installed with a common air supply, isolate the systems with a spring-
loaded, soft-seated ball check valve to ensure air integrity for each sys-
tem. Good practice is to include a ball valve for isolation and service of
each individual system.
Set the air pressure to the required system air pressure. Air pressure
differing from the required system air pressure could delay system
operation response time.
The engineer/system designer is responsible for sizing the compressor
so that the entire system is charged to the required air pressure within
30 minutes. DO NOT oversize the compressor to provide more airflow.
An oversized compressor will slow down or possibly prevent valve
operation.
If the compressor fills the system too fast, it may be necessary to
restrict the air supply. Restricting the air supply will ensure that air
being exhausted from an open sprinkler or manual release valve is not
replaced by the air supply system as fast as it is being exhausted.

BASEORRISER-MOUNTEDAIRCOMPRESSORS
For base or riser-mounted air compressors, the recommended air
pressure of 0.9 Bar/90 kPa/13 psi is the “on” or “low” pressure setting
for the compressor. The “off” or “high” pressure setting should be
1.2 Bar/124 kPa/18psi.
When a base or riser-mounted air compressor supplies air to a Series
764 FireLock NXT Alternate Wet/Dry Valve, it is not necessary to install
the Victaulic Series 757 Regulated Air Maintenance Trim Assembly
(AMTA). In this case, the air line of the compressor connects to the trim
at the fitting where the Series 757 Regulated AMTA is normally installed
(refer to the applicable trim drawing). If the compressor is not equipped
with a pressure switch, the Series 757P Air Maintenance Trim Assembly
with Pressure Switch should be installed.
SHOPAIRORTANK-MOUNTEDAIRCOMPRESSORS
In the event a compressor becomes inoperative, a properly sized tank-
mounted air compressor provides the greatest protection for systems.
When shop air or a tank-mounted air compressor is used, the Series
757 Regulated AMTA must be installed. The Series 757 Regulated
AMTA provides proper air regulation from the air reservoir to the
sprinkler system. For tank-mounted air compressors, the recommended
air pressure of 0.9 Bar/90 kPa/13 psi should be used as the set point
for the air regulator. The “on” pressure of the compressor should be at
least
0.3 Bar/24 kPa/5 psi above the set point of the air regulator.

In the event a compressor becomes inoperative, a properly sized tank-
mounted air compressor provides the greatest protection for systems
installed with a Series 746-LPA Dry Accelerator. In this situation, air can
be supplied continuously to the sprinkler system for an extended time
period. NOTE: The Series 757 Regulated AMTA should be used with
a tank-mounted air compressor to supply air to a Series 764 FireLock
NXT Alternate Wet/Dry Valve when the Series 746-LPA Dry Accelerator
is used. The use of an air regulator with a base or riser-mounted air
compressor could cause short cycling, resulting in premature wear of
the compressor.
The air regulator of the Series 757 Regulated AMTA is a relief-type
design. Any pressure in the system that is above the set point of the air
regulator will be released. Therefore, charging the air regulator above
the set point could cause premature operation of a valve installed with a
Series 746-LPA Dry Accelerator.

ALARMPRESSURESWITCHES
Air supervisory pressure switches are required for dry systems and must
be set according to the following notes:
Wire the air supervisory pressure switches to activate a low-1.
pressure alarm signal. NOTE: In addition, the local authority having
jurisdiction may require a high-pressure alarm. Contact the local
authority having jurisdiction for this requirement.
1a. Set the air supervisory pressure switches to activate at
0.1 – 0.3 Bar/14 – 28 kPa/2 – 4 psi below the minimum air
pressure required (but not lower than 0.7 Bar/69 kPa/10psi).
1b. Wire the alarm pressure switch to activate a water flow alarm.
1c. Set the alarm pressure switch to activate on a pressure rise of
0.3 – 0.6 Bar/28 – 55 kPa/4 – 8psi.
REMOTESYSTEMTESTVALVEREQUIREMENTS
The remote system test station (inspector’s test connection) contains a
valve, which can be opened to simulate the operation of a sprinkler.
The remote system test valve (inspector’s test connection) should be
located at the most hydraulically demanding location in the release
system. NOTE: Multiple restrictions on the remote system test valve
(inspector’s test connection) may slow the air decay rate and cause the
system to respond slower than required.
The remote system test valve (inspector’s test connection) should termi-
nate with an orifice equal to the smallest orifice in the releasing system.
The remote system test valve (inspector’s test connection) is used to
ensure that water reaches the most remote part of the system within 60
seconds.

IMPORTANTINSTALLATIONINFORMATION
1. For proper operation and approval, the Series 764 FireLock NXT
Alternate Wet/Dry Valve must be installed in accordance with the
specific trim diagrams included with the shipment. NOTE: Victaulic
provides specific trim diagrams for vertical installations and instal-
lations involving a Series 746-LPA Dry Accelerator.
2. Before installing the Series 764 FireLock NXT Alternate Wet/Dry
Valve, flush the water supply piping thoroughly to remove all
foreign material.
3. Series 764 FireLock NXT Alternate Wet/Dry Valves MUST NOT
be located in an area where the valve can be exposed to freezing
temperatures. In addition, the Series 764 FireLock NXT Alternate
Wet/Dry Valve MUST NOT be located in an area where physical
damage may occur.
4. It is the system designer’s responsibility to confirm material
compatibility of the Series 764 FireLock NXT Alternate Wet/Dry
Valve, trim, and associated accessories when a corrosive environ-
ment or contaminated water is present.
5. SERIES764FIRELOCKNXTALTERNATEWET/DRYVALVES
MUSTBEINSTALLEDONLYINTHEVERTICALPOSITIONWITH
THEARROWONTHEBODYPOINTINGUPWARD.
6. Air or nitrogen supply to the dry piping system must be clean, dry,
and oil-free.
7. Air supplies must be regulated, restricted, and continuous.
8. When the Series 764 FireLock NXT Alternate Wet/Dry Valve is
used with a water motor alarm, Victaulic recommends the use
of an uninterrupted, low-pressure alarm that is installed on the
diaphragm charge line downstream of the strainer/check restric-
tor. Another option is to install a Series 75B Supplemental Alarm
Device.
9. Piping must be pitched so that systems can drain properly. For
areas that are subject to high levels of condensation, or where
piping is not properly pitched, an optional Series 75D Water
Column Device kit is available to assist in automatically draining
water out of the riser when the valve is in the “dry configuration.”
NOTE: When the Series 75D Water Column Device kit is installed
in the trim of a Series 764 FireLock NXT Alternate Wet/Dry Valve,
a ball valve must be added to the inlet of the Series 75D. This inlet
ball valve must be closed while the valve is in the “wet configura-
tion” to prevent water from continuously draining from the system.
