General
Description
The Model DV-5 Double Interlock Pre-
action System with Electric/Pneumatic
Actuation (Fig. 1) is designed for use
in applications, such as refrigerated
areas, requiring the maximum degree
of protection against inadvertent flood-
ing of the sprinkler system piping.
The Model DV-5 Double Interlock Pre-
action System with Electric/Pneumatic
Actuation utilizes a Model DV-5 Deluge
Valve and a Riser Check Valve. The
Riser Check Valve (that does not re-
quire the use of priming water) isolates
the Deluge Valve from the system air
pressure. The releasing trim for the
Deluge Valve utilizes a Solenoid Valve
and a Dry Pilot Actuator in a series
configuration. The system air pressure
holds the Dry Plot Actuator closed,
whereas the Solenoid Valve remains
closed until it is electrically energized
by a Deluge Valve Releasing Panel
(automatic control unit). The Releas-
ing Panel is operated by either a fire
detection device or manual electric
pull station.
In order for the Double Interlock Pre-
action System to automatically actu-
ate, two independent events must oc-
cur. The deluge valve releasing panel
must operate and open the Solenoid
Valve upon automatic operation of the
electric fire detection initiating circuit
or manual operation of the electric-
manual pull initiating circuit, and the
sprinkler system piping must lose air
pressure due to operation of one or
more sprinklers.
The Double Interlock Preaction Sys-
tem will automatically actuate only
when both the Dry Pilot Actuator and
the Solenoid Valve are open at the
same time. Accidental opening of just
the Dry Pilot Actuator (for example: a
lift truck accidentally dislodges a sprin-
kler), or just energizing the Solenoid
Valve (for example: an accidental op-
eration of an electric pull station), will
only cause an alarm, and will not actu-
ate the system or flood the sprinkler
system piping.
The Model DV-5 Deluge Valve (de-
scribed in Technical Data Sheet
TFP1305) is a diaphragm style valve
that depends upon water pressure in
the Diaphragm Chamber to hold the
Diaphragm closed against the water
supply pressure. When the DV-5 Valve
is set for service, the Diaphragm
Chamber is pressurized through the
trim connections from the inlet side of
the system’s main control valve, for
example an O.S.&Y. gate valve or but-
terfly valve (Fig. 1).
Operation of the Solenoid Valve and
Dry Pilot Actuator at the same time
releases water from the Diaphragm
Chamber faster than it can be replen-
ished through the 1/8 inch (3,2 mm)
Priming Supply Restriction (Item 7 -
Fig. 2A) in the diaphragm supply con-
nections. This results in a rapid pres-
sure drop in the Diaphragm Chamber
below the valve trip point. The water
supply pressure then forces the Dia-
phragm open permitting water to flow

into the system piping, as well as
through the Alarm Port to actuate the
system alarms.
As water flows into the system, the
Model FSV-1 Fail-Safe Valve (Item 5 -
Fig. 2A, also described in Technical
Data Sheet TFP1386) becomes pres-
surized and upon operation constantly
vents the DV-5 Diaphragm Chamber
so as to maintain the DV-5 Valve in the
open (operated) position until the sys-
tem is reset.
WARNING
The Model DV-5 Double Interlock Pre-
action System with Electric/Pneumatic
Actuation described herein must be
installed and maintained in compli-
ance with this document, as well as
with the applicable standards of the
National Fire Protection Association,
in addition to the standards of any
other authorities having jurisdiction.
Failure to do so may impair the per-
formance of the related devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or manufac-
turer should be contacted with any
questions.

Valve Trim
The Double Interlock Preaction Sys-
tem with Electric/Pneumatic Actuation
Trim (Fig. 2A/2B) forms a part of the
laboratory listings and approvals. The
trim is necessary for proper operation
of the DV-5 Valve.
Each package of trim includes the fol-
lowing items:
•Water Supply Pressure Gauge
•Diaphragm Chamber
Pressure Gauge
•Diaphragm Chamber Connections
•Manual Control Station
•Main Drain Valve
•System Drain Valve
•Alarm Test Valve
•Automatic Drain Valve
•System Air Pressure Gauge
•Air Supply Connections
•Low Air Pressure Alarm Switch
•Waterflow Pressure Alarm Switch
•Dry Pilot Actuator
•Pressure Operated Relief Valve
To ease field assembly of the trim ar-
rangement, the trim components are
provided partially assembled as
showninFigure2B.
The trim arrangement is provided with
galvanized or black nipples and fit-
tings. The galvanized trim is intended
for non-corrosive or corrosive condi-
tions, whereas the black trim is princi-
pally intended for use with AFFF sys-
tems.
NOTE
When the system pressure is greater
than 175 psi (12,1 bar), provision is to
be made to replace the standard order
300 psi (20,7 bar) Water Pressure
Gauges, shown in Figure 2A/2B with
separately ordered 600 psi (41,4 bar)
Water Pressure Gauges.
System Design Considerations
Because a double interlock preaction
system requires time for a drop in sys-
tem air pressure to occur (concurrently
with the response time for the separate
fire detection system) before it will al-
low water to enter the system piping,
this system has characteristics similar
to a dry pipe sprinkler system. There-
fore, the system design considerations
for a dry pipe system are normally
applied to a double interlock preaction
system — including a 30% increase in
design area; a maximum 1 minute
water delivery time for system capaci-
ties of 750 gallons (2800 litres) or
more; and, prohibition of gridded sys-
tem piping.
In order to readily perform the System
Inspection Procedure described in the
Care and Maintenance section, it is

TFP1386); consequently, the release
circuit of the releasing panel need only
provide the standard ten minutes of
alarm condition intended to energize
the Solenoid Valve to open. After the
ten minute duration, at which point
should the Solenoid Valve become de-
energized and closes (especially while
operating under battery back-up), the
Fail-Safe Valve will have already auto-
matically operated to constantly vent
the DV-5 Diaphragm Chamber,
thereby preventing the DV-5 Dia-
phragm Chamber from becoming re-
pressurized and preventing an inad-
vertent closing of the DV-5 during a fire
event.
System Air Pressure Requirements
The required system air pressure for
the Double Interlock Preaction System
with Electric/Pneumatic Actuation is
shown in Graph A as a function of the
anticipated water supply pressure. It is
recommended that the system air
pressure be maintained by one of the
following methods:
•A maximum 200 psi (13,8 bar) plant
air supply in combination with the
Model AMD-1 Air Maintenance De-
vice described in Technical Data
Sheet TFP1221.
•A dedicated air compressor in com-
bination with the Model AMD-2 Air
Maintenance Device described in
Technical Data Sheet TFP1231.
•A maximum 3000 psi (206,9 bar)
nitrogen cylinder in combination with
the Model AMD-3 Nitrogen Mainte-
nance Device described in Techni-
cal Data Sheet TFP1241.
NOTES
The dew point of the air or nitrogen
supply, for a system exposed to freez-
ing conditions, must be maintained be-
low the lowest ambient temperature to
which the system piping will be ex-
posed. Introduction of moisture into
the system piping can create ice build
up which could prevent proper opera-
tion of the system.
Friction Loss
The nominal pressure loss versus flow
data for the Model DV-5 Deluge Valve
plus Riser Check Valve is provided in
Graph B.
Installation
NOTES
1-1/2 inch (DN40) risers utilize a 2 inch
(DN50) Riser Check Valve in combina-
tion with the 1-1/2 inch (DN40) Model
DV-5 Deluge Valve.
Proper operation of the Model DV-5
Deluge Valves depends upon their trim
being installed in accordance with the
instructions given in this Technical
Data Sheet. Failure to follow the ap-
propriate trim diagram may prevent
the DV-5 Valve from functioning prop-
erly, as well as void listings, approvals,
and the manufacturer’s warranties.
Field adjustments of the Air Mainte-
nance Device, Low Pressure Alarm
Switch, and Pressure Relief Valve are
required.
When using compressed air as op-
posed to compressed nitrogen for re-
frigerated area service, alternate air
supply connections with an air dryer
may be required by the Authority Hav-
ing Jurisdiction. The “1/2 Inch NPT
Connection For System Air Supply”
showninFigure2Bistobeplugged
when using an alternate air supply
connection; the location of the Air
Pressure Maintenance is to be as
specified by the Authority Having Ju-
risdiction; and, Step 10 regarding the
adjustment of the Pressure Relief
Valve can be omitted, since the Pres-
sure Relief Valve in this case will be
ineffective.
The DV-5 Valve must be installed in a
readily visible and accessible location.
The DV-5 Valve and associated trim
must be maintained at a minimum tem-
perature of 40°F/4°C.
Heat tracing of the DV-5 Valve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits that can
prevent proper operation.
The Model DV-5 Deluge Valve is to be
installed in accordance with the follow-
ing criteria:
Step 1. All nipples, fittings, and de-
vices must be clean and free of scale
and burrs before installation. Use pipe
thread sealant sparingly on male pipe
threads only.
Step 2. The DV-5 Valve must be
trimmed in accordance with Figure
2A/2B.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc. are installed with the flow
arrows in the proper direction.
Step 4. Drain tubing to the drip funnel
Page 11 of 16
TFP1460

must be installed with smooth bends
that will not restrict flow.
Step 5. The main drain and drip funnel
drain may be interconnected provided
a check valve is located at least 12
inches (300 mm) below the drip funnel.
Step 6. Suitable provision must be
made for disposal of drain water.
Drainage water must be directed so
that it will not cause accidental dam-
age to property or danger to persons.
Step 7. Connect the Diaphragm
Chamber Supply Control Valve to the
inlet side of the system’s main control
valve in order to facilitate setting of the
DV-5 Valve (Fig. 3).
Step 8. Unused pressure alarm
switch connections must be plugged.
Step 9. A suitable automatic supervi-
sory air (nitrogen) supply, as described
in the Technical Data Section, is to be
installed in accordance with the appli-
cable Technical Data Sheet. Refer to
Graph A for the system air pressure
requirements.
An air dryer, when specified, is to be
installed as required by the Authority
Having Jurisdiction.
Step 10. The Pressure Relief Valve
(P6 - Fig. 2A) is factory set to relieve at
a pressure of approximately 45 psi (3,1
bar), which can typically be used for a
maximum system pressure of 40 psi
(2,8 bar). The Pressure Relief Valve
may be reset; however, it must be reset
to relieve at a pressure that is in ac-
cordance with the requirements of the
Authority Having Jurisdiction.
To reset the Pressure Relief Valve, first
loosen the jam nut and then adjust the
cap accordingly — clockwise for a
higher pressure setting or counter-
clockwise for a lower pressure setting.
After verifying the desired pressure
setting, tighten the jam nut.
Step 11. The Low Pressure Alarm
Switch (Item P4 - Fig. 2A) is to be
adjusted to operate on falling pressure
at approximately 6 psi (0,4 bar) below
the minimum Double Interlock Dry
System air pressure requirement
shown on Graph B.
Use the instructions provided with the
switch to adjust the pressure setting.
Step 12. Conduit and electrical con-
nections are to be made in accordance
with the requirements of the authority
having jurisdiction and/or the National
Electric Code.
Step 13. Before a system hydrostatic
test is performed in accordance with
NFPA 13 system acceptance test re-
quirements, the DV-5 Diaphragm
Chamber is to be depressurized; the
Automatic Drain Valve (4, Fig. 2A) is to
be temporarily replaced with a 1/2 inch
NPT plug, the 3/32 inch Vent Fitting (17
- Fig. 2A) is to be temporarily replaced
with a 1/4 inch NPT plug, and the Dia-
phragm Cover Bolts must be uni-
formly and securely tightened using
a cross-draw sequence. After tight-
ening, double-check to make certain
that all of the Diaphragm Cover Bolts
are securely tightened.
Valve Setting
Procedure
Steps 1 through 15 are to be per-
formed when initially setting the Model
DV-5 Deluge Valve; after an opera-
tional test of the fire protection system;
or, after system operation due to a fire.
Step 1. Close the Main Control Valve.
Step 2. Close the Diaphragm Cham-
ber Supply Control Valve and the Sys-
tem Air Supply Control Valve.
Step 3. Open the Main Drain Valve,
System Drain Valve, and all auxiliary
drains in the system. After water
ceases to discharge, close the System
Drain Valve and auxiliary drain valves.
Leave the Main Drain Valve open.
NOTE
Do not open the Inspector’s Test Con-
nection and auxiliary drains if resetting
after a system test; otherwise, system
air pressure will be relieved unneces-
sarily.
Step 4. Depress the plunger of the
Automatic Drain Valve to verify that it
is open and that the DV-5 Valve is
completely drained.
Step 5. Clean the Strainer in the Dia-
phragm Chamber Supply connection
by removing the clean-out plug and
strainer basket. The Strainer may be
flushed out by momentarily opening
the Diaphragm Chamber Supply Con-
trol Valve.
Step 6. Inspect for and clear all ice
plugs where system piping has been
exposed to freezing conditions and
when there has been a flow of water
into the system.
Step 7. Replace all damaged or oper-
ated sprinklers. Replacement sprin-
klers must be of the same type and
temperature rating as those that oper-
ated.
NOTE
In order to prevent the possibility of a
subsequent operation of an over-
heated solder type sprinkler, any sol-
der type sprinklers possibly exposed
to a temperature greater than their
maximum rated ambient must also be
replaced.
Step 8. Service the air dryer, if appli-
cable, in accordance with the manu-
facturer’s instructions.
Step 9. Open the System Air Supply
Control Valve and allow the system to
automatically re-establish its nominal
system air pressure per Graph A. Ob-
serve the Automatic Drain Valve for
leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem within the Riser Check Valve.
Step 10. Reset the actuation system.
Manual Actuation — Push the operat-
ing lever up; however, do not close the
hinged cover at this time.
Electric Actuation — Reset the electric
detection system in accordance with
the manufacturer’s instructions to de-
energize the Solenoid Valve.
Step 11. Open the Diaphragm Cham-
ber Supply Control Valve and allow full
pressure to build up in the Diaphragm
Chamber.
Step 12. Operate (open) the Manual
Control Station to vent trapped air from
the Diaphragm Chamber. If necessary,
first open the hinged cover, and then
fully pull down on the operating lever.
SLOWLY close the operating lever, by
pushing it up, after aerated water
ceases to discharge from the Manual
Control Station drain tubing. Close the
hinged cover and insert a new break
rod in the small hole through the top of
the enclosing box.
Step 13. Inspect the drain connections
from the Manual Control Station and
the Dry Pilot Actuator. Any leaks must
be corrected before proceeding to the
next step.
Step 14. Verify the ability for the DV-5
Diaphragm to hold pressure as fol-
lows:
With the diaphragm chamber pressur-
ized per Step 12, temporarily close the
Diaphragm Chamber Supply Control
Valve and observe the Diaphragm
Chamber Pressure Gauge for a drop in
pressure.
If a drop in pressure is noted, the DV-5
Diaphragm is to be replaced and/or
any leaks must be corrected before
proceeding to the next step.
If the Diaphragm Chamber Pressure
Gauge does not indicate a drop in
pressure, re-open the Diaphragm
Chamber Supply Control Valve and
proceed to the next step.
Step 15. Slowly open the Main Control
Valve. Close the Main Drain Valve as
soon as water discharges from the
Page 12 of 16 TFP1460

drain connection. Observe the Auto-
matic Drain Valve for leaks. If there are
leaks, determine/correct the cause of
the leakage problem. If there are no
leaks, the DV-5 Valve is ready to be
placed in service and the Main Control
Valve must then be fully opened.
NOTES
When the Main Control Valve is
opened, the pressure on the Dia-
phragm Chamber may increase. This
increase in pressure is normal, and if
the pressure is greater than 250 psi
(17,2bar),thepressureistobere-
lieved by partially and temporarily
opening the Manual Control Station;
however, do not allow the pressure as
indicated on the Diaphragm Chamber
Pressure Gauge to drop below the
supply pressure shown on the Water
Supply Pressure Gauge, since this ac-
tion may result in tripping of the DV-5
Valve.
After setting a fire protection system,
notify the proper authorities and ad-
vise those responsible for monitoring
proprietary and/or central station
alarms.
Care and
Maintenance
The following procedures, inspections,
and maintenance must be performed
as indicated, in addition to any specific
requirements of the NFPA, and any
impairment must be immediately cor-
rected.
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association (e.g., NFPA 25), in
addition to the standards of any
authority having jurisdiction. The in-
stalling contractor or product manufac-
turer should be contacted relative to
any questions.
It is recommended that automatic
sprinkler systems be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
It is recommended that the System
Inspection Procedure be performed at
least semi-annually by a qualified In-
spection Service. The Double Interlock
Preaction System Inspection Proce-
dure may be followed in lieu of per-
forming any of the operational tests
recommended in the Technical Data
Sheets for the Model DV-5 Deluge
Valve, Riser Check Valve, 24 VDC So-
lenoid Valve, Dry Pilot Actuator, and
Model MC-1 Manual Control Station.
NOTES
It is recommended that the individuals
responsible for the care and mainte-
nance of the Double Interlock Preac-
tion System develop a working under-
standing of the system, in general,
prior to performing inspection and/or
maintenance procedures. These in-
structions, as well as individual in-
structions for the deluge valve, riser
check valve, solenoid valve, dry pilot
actuator, manual control station,
switches, and pressure maintenance
device should be reviewed.
The following procedures pertain to
the automatic control valve portion of
the Double Interlock Preaction Sys-
tem. Refer to the manufacturer’s in-
structions and NFPA 25 for care and
maintenance procedures for all other
devices (e.g., electric detection, main
control and system shut-off valves, su-
pervisory devices, sprinklers, etc.).
Before performing the System Inspec-
tion Procedure, which will result in op-
eration of alarms, notify the proper
authorities and all personnel who may
be affected.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
System Inspection Procedure
Step 1. Close the Main Control Valve
(Fig. 1) and then open the DV-5 Main
Drain Valve (Fig. 2B).
Step 2. Manually operate Deluge
Valve Releasing Panel, and verify the
following:
•Verify the operation of the Releasing
Panel and its associated alarms.
•Verify that there is no leakage from
the Dry Pilot Actuator (Fig. 2B).
NOTES
During this procedure, the Solenoid
Valve is opened; however, the Dry Pi-
lot Actuator should remain closed and
the DV-5 Deluge Valve Diaphragm
Chamber should remain pressurized.
This procedure is used to verify that
the DV-5 Deluge Valve will remain set
if the electric detection system oper-
ates but the sprinkler system remains
in its normally pressurized condition.
Step 3. Open the Inspector’s Test Con-
nection but be prepared to close it im-
mediately after verifying that the Low
Pressure Alarm Switch (Fig. 2B) and
its associated alarms operate properly.
The Low Pressure Alarm Switch
should operate at the previously estab-
lished pressure (refer to Installation
section, Step 11).
Close the Inspector’s Test Connection.
Step 4. Close the Diaphragm Chamber
Supply Control Valve (Fig. 2B).
Step 5. Close the System Shut-off
Valve (Fig. 1) after the system air pres-
sure has been restored to normal.
Step 6. Manually restore the electric
fire detection system to a normal con-
dition in accordance with the manufac-
turer’s instructions.The Solenoid Valve
will then be de-energized and returned
to its normally closed position.
Step 7. Open the Diaphragm Chamber
Supply Control Valve (Fig. 2B).
Step 8. Open the Main Control Valve
(Fig. 1) one turn beyond the position at
which water just begins to flow from
the Main Drain Valve.
Page 13 of 16
TFP1460

Step 9. Close the Main Drain Valve
(Fig. 2B).
Step 10. Close the Air Supply Control
Valve (Fig. 2B).
Step 11. Open the Dry Pilot Actuator
by partially opening the System Main
Drain Valve (Fig. 2B) to relieve air pres-
sure at the inlet to the Actuator. Verify
that there is no leakage from the Dry
Pilot Actuator.
NOTES
During this procedure, the Dry Pilot
Actuator is opened; however, the So-
lenoid Valve should remain closed and
the DV-5 Deluge Valve Diaphragm
Chamber should remain pressurized.
This procedure is used to verify that
the DV-5 Deluge Valve will remain set
if the Dry Pilot Actuator operates due
to loss of system air pressure and the
electric detection system remains in a
normal condition.
Step 12. Open (energize) the Solenoid
Valve by operating the deluge valve
releasing panel, and verify the follow-
ing:
•Verify that the DV-5 Valve operates,
as is indicated by a discharge of
water from the System Main Drain
Valve and the Automatic Drain
Valve. The Automatic Drain Valve
may or may not close depending on
the flow past the partially open Main
Control Valve.
•Verify that the Model FSV-1 Fail-
Safe Valve has operated as is indi-
cated by water discharging into the
Drip Funnel from the 1/2 inch drain
tube connected to the Model FSV-1
Fail-Safe Valve.
•Verify that the Waterflow Pressure
Alarm Switch (Fig. 2B) and its asso-
ciated alarms properly operate.
•Verify that the Water Motor Alarm, if
applicable, properly operates.
NOTE
This procedure simulates opening of
both the Dry Pilot Actuator (loss of
system air pressure) and Solenoid
Valve (operation of the deluge valve
releasing panel) to verify automatic
system operation.
Step 13. Reset the Double Interlock
Preaction System in accordance with
the Resetting Procedure section.
Fail-Safe Valve
If water does not discharge from the
1/2 inch tube connected to the Model
FSV-1 Fail-Safe Valve during Step 12
of the System Inspection Procedure,
the Model FSV-1 Fail-Safe Valve is to
be disassembled, cleaned, and in-
spected as follows:
Step 1. Take the sprinkler system out
of service by using Steps 1 through 4
of the Resetting Procedure.
Step 2. Remove the FSV-1 from the
Double Interlock Preaction Trim.
Step 3. Refer to Technical Data Sheet
TFP1386 and completely disassem-
ble the FSV-1.
Step 4. Clean all parts, and replace
worn or damaged parts as necessary
Step 5. Reassemble the FSV-1 in ac-
cordance with Technical Data Sheet
TFP1386 and then reinstall the FSV-1
into the Double Interlock Preaction
Tr i m .
Step 6. Place the system into service
in accordance with the Resetting Pro-
cedure section and then perform the
System Inspection Procedure to verify
proper operation of the system, as well
as the FSV-1 Fail-Safe Valve.
Quarterly Waterflow Alarm Test
Procedure
Testing of the system waterflow alarms
must be performed quarterly. To test
the waterflow alarm, open the Alarm
Test Valve, which will allow a flow of
water to the Waterflow Pressure Alarm
Switch and/or Water Motor Alarm.
Upon satisfactory completion of the
test, close the Alarm Test Valve.
