and AutoConvert Dry Trim
The patented Victaulic Series 769 FireLock NXTw Preaction Valve controls the water sup-
ply entry into the Preaction system piping and sprinklers. The preaction system is normally
supervised with pressurized air or nitrogen in order to detect any leaks in the system. The
Series 769 valve is a low differential, latched clapper valve that uses a unique, direct -acting
diaphragm to separate system water supplies from Preaction pipe sprinkler systems. The posi-
tive latching mechanism uses the supply water pressure from upstream (city side) of the main
control valve to hold the clapper shut. When the water pressure in the diaphragm chamber is
released the latch retracts from the clapper and the valve actuates. The low differential and
unique latch and actuator design of the valve allow the valve to be self -resetting; therefore it is
not necessary to remove the cover. The low differential design is not subject to water columns.
AutoConvert Dry Trim Option: Recommended for Preaction applications where reliability of
power supply is a concern. In the event of an AC power loss, the AutoConvert module latches
from Closed to Open with a quick electrical pulse. To stay open, no further current draw is
required as would be needed in a normally -open solenoid. This opened pathway allows the
included Series 776 Low Pressure Actuator to operate as a dry actuator, putting the preaction
system into a Non -Interlocked condition. In this case, an air loss in the system piping or an
electrical release from the Fire Alarm Control Panel (FACP) would allow the Series 769 valve
to actuate, filling the piping with water. Upon an AC power return, the Auto -Convert module
senses the restoration and latches the path from the Series 776 Low Pressure Actuator closed,
returning the preaction valve to its standard release method.

The valve allows the water to operate a water motor alarm and/or electric pressure alarms, which
continue until the flow of water stops.
The valve is rated to 30Opsi/2065kPa water working pressure and is factory tested hydrostatically to
6OOpsi/4135kPa for sizes 144-8740-200mm. Required air pressure is 13psi/90kPa. The Series
769 is available grooved x grooved. Standard grooved dimensions conform to ANSI/AWWA C606.
Victaulic Series 769 Preaction valves do NOT require a separate check valve in the preaction system
and feature a straight -through valve body design that provides superior flow and low-pressure drop.
The valve body is tapped with a special drain for a complete system. The valve has simple access to
all internal parts for easy maintenance. All internal parts are replaceable.
Maintenance and service can be performed from the installed position. The rubber clapper seal is
replaced easily without removing the clapper from the valve. The body is tapped for main drain and
all available trim configurations. The valve is painted inside and out to increase corrosion resistance.
The Victaulic Series 769 FireLock NXT Preaction valve trim includes an alarm test valve, which
allows testing of the alarm system without reducing the system pressure.
NOTE: The bare value carries VdS approvals for deluge applications only. There is no Vol recognition
of the preaction configurations. The AutoConvert trim configurations are FM and LPCB Approved
only.

INSTALLATION OPTIONS Vic -Quick Riser
The Vic -Quick Riser comes completely pre -trimmed and includes a shut off valve (uses a Series
705W or Series 705 Firel-ock Butterfly valve — request publication 10.18 or 10.81. For 1 V2 and 2740 `x!
and 50mm sizes, the Vic -Quick Riser may come with a Series 728 Ball Valve — request publication
10.17) for system shut off, pre-set pressure switches, and a drain kit for ease of installation.
RELEASE MECHANISM OPTIONS Single Interlocked
Single -interlocked systems are designed so that either an event detection by the release mechanism
or loss of supervisory air in the sprinkler system will cause the valve to operate. When the valve oper-
ates, water will enter the sprinkler system and flow from any open sprinklers or other openings in the
system.
PneumaticlElectric Release: The Victaulic electric release system uses an electric solenoid valve,
approved electric panel and a compatible detection system. When EITHER an electric 54ction or a
system sprinkler operates, the water in the diaphragm chamber is released and the alve operates. If
there is an electric detection and a system sprinkler does not operate, water will ill the sprinkler sys-
tem, alarms will be activated and the Victaulic Series 769 Actuated Valve will Was an Alarm Check
Valve. If the valve is actuated by the activation or damage of a sprinkler sy m sprinkler, water will
enter the system and flow from any open sprinklers. Alarms will activate,' ue to water entering the
intermediate chamber of the valve.
Electric Release: The Victaulic Electric Release System uses an electric solenoid valve, approved
electric panel and a compatible detection system. Only when.X release system event occurs, will the
water in the diaphragm chamber be released and the vale operate. Pneumatic pressure is main-
tained in the sprinkler system only for supervisory purposes and a low pressure alarm is installed in
the sprinkler system in order to detect any leaks in tWsystem. If there is an electric release activa-
tion and a sprinkler system sprinkler does not operate, the valve will operate and water will fill the
sprinkler system, alarms will be activated andjhe Victaulic Series 769 Actuated Valve will act as an
Alarm Check Valve. If a system sprinkler is damaged or activates and there is no release mechanism
detection, the low pressure alarm in the system will activate but the valve will not operate and no
water will flow until there is a release detection.
AutoConvert Trim: In the event of aKAC power loss, the AutoConvert module latches from Closed
to Open with a quick electrical pulse. To stay open, no further current draw is required as would
be needed in a normally open'solenoid. This opened pathway allows the included Series 776 Low
Pressure Actuator to operate as a dry actuator, putting the preaction system into a Non -Interlocked
condition. In this case„an air loss in the system piping or an electrical release from the FACP would
allow the Series 769'valve to actuate, filling the piping with water. Upon an AC power return, the
Auto -Convert module senses the restoration and latches the path from the Series 776 Low Pressure
Actuator closed, returning the preaction valve to its standard release method. This automatic sensing
and automatic action allows continuous fire protection in the event of an AC power loss and possible
batterybackup failure.

RELEASE MECHANISM OPTIONS Double Interlocked /
Double interlocked systems are designed so that the valve will actuate only in the event of multiple
fire detections by the release mechanisms. If a single release event occurs alarms will sound but the
valve will not operate and water will not flow until a second release event is detected. Double inter-
locked systems are commonly used in refrigerated systems and in systems where water entering the
sprinkler system is critical as well as when accidental discharge of water is critical.
Pneumatic/Electric Release: The electric/pneumatic preaction system uses both an electric release
system, (composed of an approved solenoid valve, electric panel and an appropriate sensor), and
pneumatically pressurized sprinkler system. The Victaulic Series 769 Actuated Valve will activate
ONLY when there is a pressure loss in the sprinkler system AND the electric detection of a release
event. In the event of a loss of pressure in the sprinkler system without an electric detection the valve
will not actuate until a second release event is detected. In this way if there is accidental damage to
the sprinkler system no water will flow. Additionally, if there is an electric detection and no pressure
loss in the sprinkler system the valve will not actuate. Alarms will activate in both cases alerting the
user of a detection condition.
Electric-Pneumatic/Electric: The electric-pneumatic/electric release uses two electric detection
devices, a fire detection device and a low pressure switch installed in the sprinkler system. Both
electric detection devices are wired into an approved control panel in a "cross -zoned" configuration.
The electric control panel controls a solenoid valve piped to the Victaulic Series 769 Actuated Valve
piston. In the event of a fire detection device activation and no pressure toss in the sprinkler system
the control panel will not trigger the solenoid valve and the valve will not actuate. If there is a loss
of pressure in the sprinkler system due to damage or a sprinkler activating and no fire detection the
control panel will not trigger the solenoid and the valve will not actuate. The valve will actuate ONLY
when BOTH a fire detection event and loss of system pressure occurs. When BOTH signals are
received by the control panel the panel triggers the solenoid valve. This allows the water supply pres-
sure in the Series 769 diaphragm chamber to be released and the valve will actuate allowing water
into the system.
Electric/Electric: The electric/electric release uses two zones of electric detection devices Installed
in the sprinkler system. Both zones of electric detection devices are wired into an approved control
panel in a "cross -zoned" configuration. The electric control panel controls a solenoid valve piped to
the Victaulic Series 769 Actuated Valve diaphragm charge line. In the event of a single electric fire
detection device activation, the control panel will not trigger the solenoid valve and the valve will not
actuate. If there is a loss of pressure in the sprinkler system due to damage or a sprinkler activating
and no fire detection the control panel will not trigger the solenoid and the valve will not actuate.
The valve will actuate ONLY when BOTH zones of electric fire detection devices are activated. When
BOTH signals are received by the control panel, the panel triggers the solenoid valve. This allows the
water supply pressure in the Series 769 diaphragm chamber to be released and the valve will actuate
allowing water into the system. In this configuration, a minimum air pressure is required to maintain
supervisory alarms and low pressure switches.
AutoConvert Trim: In the event of an AC power loss, the AutoConvert module latches from Closed
to Open with a quick electrical pulse. To stay open, no further current draw is required as would
be needed in a normally open solenoid. This opened pathway allows the included Series 776 Low
Pressure Actuator to operate as a dry actuator, putting the preaction system into a Non -Interlocked
condition. In this case, an air loss in the system piping or an electrical release from the FACP would
allow the Series 769 valve to actuate, filling the piping with water. Upon an AC power return, the
Auto -Convert module senses the restoration and latches the path from the Series 776 Low Pressure
Actuator closed, returning the preaction valve to its standard release method. This automatic sensing
and automatic action allows continuous fire protection in the event of an AC power loss and possible
battery backup failure.

AIR SUPPLY REQUIREMENTS The required air pressure for Series 769 FireLock NXT Preaction Valves is 13 psi/9OkPa minimum,
regardless of the system supply pressure. Air pressures should be kept below 18psi/124kPa, unless
a Series 746 -LPA Dry Accelerator is installed. Systems with air pressures higher than 18psi/124kPa
may require the addition of a Series 746 -LPA Dry Accelerator.
If multiple Series 769 FireLock NXT Preaction 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 system.
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 Sys-
tem air pressure could reduce 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.

COMPRESSOR REQUIREMENTS
A tank -mounted air compressor with a Series 757 Regulated AMTA must be used to supply air to
AND SETTINGS FOR SERIES 769
a Series 769 FireLock NXT Preaction Valve installed with a Series 746 -LPA Dry Accelerator. In the
FIRELOCK NXT PREACTION VALVES
event a compressor becomes inoperative, a properly sized tank -mounted air compressor provides the
INSTALLED WITH SERIES 746 -LPA
greatest protection, since air can be supplied continuously to the sprinkler system for an extended
DRY ACCELERATORS
time period. In addition, a properly -sized tank -mounted air compressor prevents clogging of the dry
accelerator's orifice.
Set the air regulator of the Series 757 Regulated AMTA to a minimum of 0.9 Bar/13 psi. 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.
SETTINGS FOR AIR SUPERVISORY 1. Air supervisory pressure switches are required for preaction systems and must be set according
PRESSURE SWITCHES AND ALARM to the following notes. NOTE: Switches for Vic -Quick Risers are pre-set at the factory.
PRESSURE SWITCHES • a. Wire the air supervisory p y pressure switches to activate aloes -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.
• b. Set the air supervisory pressure switches to activate at
0.1— 0.38ar/2 — 4psi below the minimum air pressure required (but not lower than
0.7 Bar/lOpsi).
• c. Wire the alarm pressure switch to activate a water flow alarm.
• d. Set the alarm pressure switch to activate on a pressure rise of 0.3 — 0.6 Bar/4 — 8psi
above the pressure required.
• e. System also includes a low water alarm pressure switch that is factory set and trips on
falling pressure of less than 124 kPa/18 psi. Trip level can be field adjusted higher if
necessary.
REMOTE SYSTEM TEST VALVE The remote system test valve (inspector's test connection) should contain a normally closed valve,
REQUIREMENTS 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 hydrauli-
cally 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 terminate 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 the required time.
