DV-5aAutomatic Water Control Valve, Single
Interlock Preaction, Electric Actuation, Fire Protec-
tion Systems 1 1/2 to 8 Inch (DN40 to DN200)
General
Description
The TYCO DV-5aAutomatic Water
Control Valve Single Interlock Preaction
Electric Actuation is a diaphragm type
valve that can be used in single inter-
lock preaction fire protection systems.
When properly trimmed, the double
seat design of the DV-5aValve also
provides actuation of fire alarms upon
system operation.
The diaphragm style design of the
DV-5aValve allows external resetting,
providing for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
The DV-5afeatures internal and exter-
nal coating of the valve to provide
corrosion resistance. The external cor-
rosion resistance of the epoxy coating
permits the use of the DV-5ain cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
The DV-5aSingle Interlock Preac-
tion Electric Actuation Valve is offered
with or without a System Main Control
Valve.
The DV-5aSingle Interlock Preaction
Electric Actuation Valve utilizes auto-
matic sprinklers and a supplemental
detection system, comprised of electric
detection comprised of heat detectors,
smoke detectors, and manual pull sta-
tions. Actuation of the detection system
automatically operates (releases) the
DV-5aValve, allowing water to flow
into the sprinkler piping system and to
be discharged from any sprinklers that
may subsequently open.

DV-5aVALVE OPERATION, PREACTION SYSTEMS

TFP1421
Page 4 of 18
Typically, the system designer selects
the detection components for a single
interlock preaction system that will
respond to a fire sooner than the auto-
matic sprinklers. Consequently, the
system will experience a minimal delay
in water delivery over that for a wet pipe
sprinkler system because the system
will have essentially filled with water
before a sprinkler operates. The DV-5a
Single Interlock Preaction Electric
Actuation Valve automatically super-
vises the integrity of the overall system.
Supervision is provided by monitoring a
relatively low air pressure in the system
via a low pressure alarm switch so as
to detect leaks in the system that oth-
erwise would result in unwanted water
discharge should the system operate in
a fire condition.
Supervised single interlock preac-
tion systems are generally used to
protect areas where there is danger
of serious water damage that might
result from damaged automatic sprin-
klers or piping. Typically, such areas
include computer rooms, storage
areas for valuable artifacts, libraries,
and archives.
Single interlock preaction systems are
also effectively used to protect proper-
ties where a pre-alarm of a possible fire
condition may allow time for fire extin-
guishment by alternate suppression
means, prior to a sprinkler discharge.
In the event the fire cannot otherwise
be extinguished, the preaction sprinkler
system will then perform as the primary
fire protection system.
NOTICE
The DV-5aSingle Interlock Preaction
Electric Actuation Valve described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the NATIONAL FIRE PRO-
TECTION ASSOCIATION (NFPA), in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

If the addition of an Alarm Control Valve
is desired or required by the local AHJ,
the Alarm Control Valve noted as Item
H in Figure 8 is to be a separately
ordered electronically supervised nor-
mally open valve.
External trim connections are NPT
threaded. EMEA trim is provided with
NPT x ISO 7-1 thread adapters.

Operation
The TYCO DV-5aValve is a diaphragm
style valve that depends upon water
pressure in the Diaphragm Chamber
(see Figure 2A) to hold the Diaphragm
closed against the water supply
pressure.
When the DV-5aValve is set for service,
the Diaphragm Chamber is pressurized
through the trim connections from the
inlet side of the system’s main control
valve.
Opening the Electric Actuation Trim
trips the Model MRA-1 Manual Reset
Actuator. Tripping the MRA-1 releases
water from the DV-5aDiaphragm
Chamber faster than it can be replen-
ished through a 1/8 in. (3,2 mm) restric-
tion located in the Diaphragm Chamber
Supply Connection. Release of water
through the MRA-1 results in a rapid
pressure drop in the DV-5aDiaphragm
Chamber. The force differential applied
through the Diaphragm to hold the
Diaphragm in the set position is then
reduced below the valve trip point. The
water supply pressure then forces the
Diaphragm open permitting water to
flow into the system piping, as well as
through the Alarm Port to actuate the
system alarms (see Figure 2B).
Upon opening of the DV-5aValve, the
Model MRA-1 Manual Reset Actuator
opens to constantly vent the DV-5aDia-
phragm Chamber to hydraulically latch
the DV-5ain the tripped position until
manually reset.
In standby mode, the integrity of the
system piping is supervised by a low
pressure alarm switch.
See the Electric Actuation section for
additional information.
Electric
Actuation
The Electric Actuation Trim forms a part
of the laboratory approval of the DV-5a
Valves and is necessary for their proper
operation.
The Electric Actuation Trim is required
for electric operation of the DV-5aValve
by a detection system consisting of
electrical devices such as heat sen-
sitive thermostats, smoke detectors,
and/or electric manual pull stations as
shown in Figure 4.
Note: For Single Interlock Preaction
Systems with Electric Actuation,the system
designertypicallyselects electric detection
devices that will operate sooner than the
automatic sprinklers chosen for use on the
sprinkler piping.
Dimensions are provided in Figure 7.
Notes:
The normally closed, de-energized,
Solenoid Valve is separately ordered and
selected based on the required laboratory
approval acceptable to the authority having
jurisdiction. Refer to Technical Data Sheet
TFP2180 for specific laboratory approvals.
Consult with the applicable standards of
the Approval agency regarding installation
criteria pertaining to electric actuation
circuitry.
Due to the functionality of the Model
MRA-1 Manual Reset Actuator, the
release circuit of the releasing panel
need only provide the typical 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 close (espe-
cially while operating under battery
back-up), the MRA-1 will have already
automatically opened, thereby pre-
venting the DV-5aDiaphragm Chamber
from becoming re-pressurized, and
preventing an inadvertent closing of
the DV-5aduring a fire event.

Installation
The TYCO DV-5ASingle Interlock Pre-
action Electric Actuation Trim Valve is
to be installed in accordance with this
section.
NOTICE
DV-5A Automatic Water Control Valves
are designed to be used in freshwater
systems. When the supply is from an
alternative source such as brackish
water, saltwater, or contains additives
such as foam, the limited warranty is
reduced to one year from the time of
installation. An increase in frequency of
inspections is required when the valve
is exposed to such supplies and other
corrosive conditions or chemicals that
could impact valve materials or the
operation of the assembly. The system
and all components must be designed
accordingly for the increased demand.
It is required to thoroughly flush the
valve and trim assembly with freshwa-
ter and reset to the set condition after
each operation.
Proper operation of the DV-5aSingle
Interlock Preaction Electric Actua-
tion Valve depends upon their trim
being installed in accordance with the
instructions given in this technical data
sheet. Failure to follow the appropriate
trim diagram may prevent the DV-5a
Valve from functioning properly, as well
as void approvals and the manufactur-
er’s warranties.
The DV-5aValve must be installed in a
readily visible and accessible location.
The DV-5aValve and associated trim
must be maintained at a minimum tem-
perature of 40°F (4°C).
Heat tracing of the DV-5aValve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits that are
capable of preventing proper operation.
Always open the system control valves
slowly to avoid a sudden rush of water
entering the system.
The DV-5aValve is to be installed in
accordance with the following criteria:
Step 1. All nipples, fittings, and devices
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-5aSingle Interlock Pre-
action Electric Actuation Valve must be
trimmed in accordance with the trim
illustration shown in Figure 5.
Note:If the addition of an Alarm Control
Valve is desired or required by the local
AHJ, the Alarm Control Valve noted as
Item H in Figure 8 is to be a separately
orderedelectronicallysupervised normally
open valve.
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
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 in.
(300 mm) below the Drip Funnel.
Step 6. Suitable provision must be
made for disposal of drain water. Drain-
age water must be directed such that
it will not cause accidental damage to
property or danger to persons.
Step 7. Connect the Diaphragm Supply
Valve to the inlet side of the System
Main Control Valve in order to facilitate
setting of the DV-5aValve (see Figure
8).
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 and set for
10 ± 2 psi (0,69 ± 0,14 bar).
Step 10. A desiccant dryer, when
required for the supervisory air supply,
is to be installed between a drip leg
and the Model AMD-1 Air Mainte-
nance Device or between the Model
G16AC812 Automatic Supervisory Air
Supply and the Preaction Trim.
Step 11. The Supervisory Low Pressure
Switch is to be wired to the supervisory

Step 12. Conduit and electrical con-
nections are to be made in accordance
with the applicable standards of the
approval agency.
Step 13. Before a system hydrostatic
test is performed, the DV-5aDiaphragm
Chamber is to be depressurized, the
Automatic Drain Valve is to be tem-
porarily replaced with a plug, and the
Diaphragm 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. See Table B in

Valve Setting
Procedure
Perform Steps 1 through 16 when ini-
tially setting the TYCO DV-5aElectric
Actuation Valve, after an operational
test of the fire protection system, or
after system operation due to a fire.
See Figure 8.
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P).
Step 3. Close the Supervisory Air
Supply Valve (S).
Step 4. Open the Main Drain Valve (D),
System Drain Valve (E), and all auxil-
iary drains in the system. Close the
auxiliary drain valves and the System
Drain Valve (E) after water ceases to
discharge. Leave the Main Drain Valve
(D) open.
At this time make certain that the
Pressure Gauge Valves and the Alarm
Control Valve (H), as applicable, are
open.
Step 5. Depress the plunger of the
Automatic Drain Valve (F) to verify that
it is open.
Step 6. Clean the Diaphragm Supply
Strainer (Q) by removing the clean-
out plug and strainer basket. The Dia-
phragm Supply Strainer (Q) may be
flushed out by momentarily opening
the Diaphragm Supply Valve (P).
Step 7. Replace any operated sprin-
klers on the system piping, as
applicable.
Step 8. Reset the automatic actuation
system. Reset the electric detection
system in accordance with the manu-
facturer’s instructions to de-energize
the solenoid valve.
Step 9. Operate (open) the Manual
Control Station (M) and then open
the Diaphragm Supply Valve (P). After
unaerated water ceases to discharge
from the Manual Control Station (M)
drain tube, slowly close the operating
lever by pushing it up. Do not close the
hinged cover at this time.
Step 10. After allowing water to flow
out of the Manual Reset Actuator (N)
drain tube until aerated water ceases
to discharge, reset the Manual Reset
Actuator (N) by pressing the Reset
Knob and hold until water stops flowing
from its drain tube and the pressure
builds and reaches approximately 15
psi (1,0 bar) on the Diaphragm Gauge
(K). Pressure will then build up in the
DV-5aDiaphragm Chamber.
Step 11. Verify the ability for the DV-5a
Diaphragm to hold pressure as follows:
• With the diaphragm chamber
pressurized per Step 10, tempo-
rarily close the Diaphragm Supply
Valve (P), and then observe the
Diaphragm Gauge (K) for a drop in
pressure.
• If a drop in pressure is noted, the
DV-5aDiaphragm is to be replaced
and/or any leaks must be corrected
before proceeding to the next step.
• If the Diaphragm Gauge (K)
indicates no drop in pressure,
re-open the Diaphragm Supply
Valve (P) and proceed to the next
step.
Step 12. Open the Supervisory Air
Supply Valve (S) to reestablish super-
visory system air pressure at nominally
10 psi (0,68 bar).
Step 13. Partially open the System
Main Control Valve (B). Slowly close the
Main Drain Valve (D) as soon as water
discharges from the Main Drain Valve
(D). Observe the Automatic Drain Valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem before proceeding.
NOTICE
When the System Main Control Valve
(B) is partially opened, the pressure on
the DV-5aDiaphragm Chamber may
increase. This increase in pressure is
normal, and if the pressure is greater
than 300 psi (20,7 bar), the pressure
is to be relieved by partially and tem-
porarily opening the Manual Control
Station (M); however, do not allow
the pressure as indicated on the Dia-
phragm Gauge (K) to drop below the
supply pressure shown on the Water
Supply Gauge (J), since this action may
result in tripping of the DV-5aValve.
Step 14. Close the hinged cover of the
Manual Control Station (M) and insert a
new break rod in the small hole through
the top of the enclosing box.
Step 15. Fully open the System Main
Control Valve (B).
Step 16. After setting a fire protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.

Care and
Maintenance
The following procedures and inspec-
tions must be performed as indicated,
in addition to any specific require-
ments of the NFPA and any applicable
standards recognized by the Approval
agency. Any impairment must be imme-
diately corrected. See Figure 8.
NOTICE
If the water supply needs to be shut off
to the DV-5avalve and trim and cannot
be shut off upstream of the system,
close the System Main Control Valve
(B), the Diaphragm Supply Valve (P),
and the Inverted Flare Shut-Off Valve
(R). This will allow any trim above the
System Main Control Valve (B) to be
taken apart for service if necessary.
The frequency at which the following
procedures and inspections are to be
performed are to be in accordance with
the NFPA and any applicable specific
requirements of the standards recog-
nized by the Approval agency.
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 systems
must first be obtained from the proper
authorities and all personnel who may
be affected by this action must be
notified.
The owner is responsible for the
inspection, testing, and maintenance
of their fire protection system and
devices in compliance with this docu-
ment, as well as with the NFPA and any
applicable standards recognized by the
Approval agency. Contact the install-
ing contractor or product manufacturer
with any questions.
Some procedures in this section result
in the operation of the associated
alarms. Notify the owner and the fire
department, central station, or other
signal station to which the alarms are
connected before performing the tests.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with the
NFPA and any applicable standards
recognized by the Approval agency.
Drop in Water Supply Pressure
Below Normal Range
NOTICE
If the water supply pressure is signif-
icantly reduced below the normally
expected static pressure range (as
could occur in the case of a water main
break or repair), and there is a subse-
quent drop in the diaphragm chamber
water pressure below its normal range
(for example, due to a leak in a piping
connection to or from the diaphragm
chamber or, a leak in the diaphragm
chamber check valve caused by dirt or
debris in the check valve seal area), a
deluge valve such as the DV-5acould
inadvertently trip, if its water supply
pressure is quickly restored.
A drop in the water supply pressure
to below its normal range (as in the
case of an interrupted water supply
condition) constitutes an emergency
impairment.
Should this condition occur, immedi-
ately close the System Main Control
Valve (B) and use the following proce-
dure to reset the system:
Step 1. Prior to the water supply pres-
sure being restored to the closed
System Main Control Valve (B), note the
pressure indicated by the Diaphragm
Gauge (K) and determine if the pres-
sure is within the normally expected
range.
Step 2. If the diaphragm chamber pres-
sure is below the normal range, check
for and correct any source of leakage
from the diaphragm chamber prior to
resetting the system.
Step 3. After the water supply pres-
sure is restored to the System Main
Control Valve (B), reset the DV-5aValve
in accordance with the Valve Setting
Procedure section.
NOTICE
For fire protection systems subject to
an emergency impairment caused by
an interrupted water supply condition,
it is recommended that consideration
be given to installing a low water supply
pressure switch with the appropriate
alarm/indications to monitor the water
supply pressure.
Waterflow Alarm Test Procedure
To test the waterflow alarm, open the
Alarm Test Valve (G), which will allow a
flow of water to the Waterflow Pressure
Switch (C) and/or Water Motor Alarm.
Upon satisfactory completion of the
test, close the Alarm Test Valve (G).
To ensure drainage of the alarm line,
depress the plunger on the Automatic
Drain Valve (F).
Supervisory Low Pressure Alarm
Test Procedure
Proper operation of the Supervisory
Low Pressure Switch (U) must be per-
formed as follows:
Step 1. Open the System Drain Valve
(E) just enough to slowly relieve super-
visory air pressure from the system.
Verify that the Supervisory Low Pres-
sure Switch (U) is operational and that
the low pressure set point is approxi-
mately 5 psi (0,34 bar).
Step 2. Close the System Drain Valve
(E) and allow the system supervisory
pressure of 10 ± 2 psi (0,69 ± 0,14 bar)
to be automatically re-established. The
Supervisory Low Pressure Switch (U)
should return to its normal condition.
Pressure Relief Valve Maintenance
Over pressurization of the system
piping with air will result in the opening
of the Supervisory Air Pressure Relief
Valve (T). If the Supervisory Air Pres-
sure Relief Valve (T) continues to bleed
air after the system pressure has been
reduced to its normal supervisory pres-
sure range of 10 ± 2 psi (0,69 ± 0,14 bar),
most likely debris became lodged in the
seating area. To help clean the seating
area, slowly pull up on the ring at the
top of the Supervisory Air Pressure
Relief Valve (T) to allow a full flow of air
through the Supervisory Air Pressure
Relief Valve (T), and then release the
ring to allow the Supervisory Air Pres-
sure Relief Valve (T) to snap closed.
Repeat the cleaning procedure as
necessary.
Electric Actuation Solenoid Valve
Test Procedure
Proper operation of the Solenoid Valve
(V) for electric actuation must be veri-
fied at as follows:
Step 1. Close the System Main Control
Valve (B).
Step 2. Open the Main Drain Valve (D).
Step 3. Test the deluge releasing panel
in accordance with the manufacturer’s
instructions to energize the solenoid
valve.
Step 4. Verify that there is a flow of
water from the Solenoid Valve drain
connection.
Step 5. Verify that the Diaphragm
Chamber pressure has decreased
to below 25% of the water supply
pressure.

TFP1421
Page 15 of 18
Step 6. Reset the electric detection
system in accordance with the manu-
facturer’s instructions to de-energize
the Solenoid Valve (V), and proceed as
follows:
• Water should cease draining from the
Solenoid Valve (V) but remain drain-
ing from the Manual Reset Actuator
(N).
• Press the Reset Knob on the Man-
ual Reset Actuator (N) and hold it a
few seconds until water stops flow-
ing from its drain tube.
• Pressure will then build up in the
DV-5aDiaphragm Chamber.
• After system pressure is restored
in the DV-5aDiaphragm Chamber,
inspect the Solenoid Valve (U) and
Manual Reset Actuator (N) for leaks
at the drain tube. Any leaks must be
corrected before proceeding to the
next step.
Step 7. Partially open the System Main
Control Valve (B). Slowly close the Main
Drain Valve (D) as soon as water dis-
charges from the Main Drain Valve (D).
Observe the Automatic Drain Valve
(F) for leaks. If there are leaks, deter-
mine/correct the cause of the leakage
problem. If there are no leaks, the
DV-5aValve is ready to be placed in
service and the System Main Control
Valve (B) must then be fully opened.
Internal Valve Inspection
Once every five years during the annual
operational test procedure and prior
to the DV-5aValve being reset and
with the DV-5aValve de-pressurized,
the interior of the DV-5aValve must
be cleaned and inspected for wear
and damage. Damaged or worn parts
must be replaced. (Replacement of the
Diaphragm every ten years is recom-
mended, or more frequently if inspec-
tions and/or wear and tear warrant
more frequent replacement.)
NOTICE
The Diaphragm Cover may be removed
between Steps 4 and 5 of the reset-
ting instructions, since at that point the
DV-5aValve should be de-pressurized
as evident by a zero gauge reading on
the Diaphragm Gauge (K) and Water
Supply Gauge (J), as well as no water
discharging from the Automatic Drain
Valve (F).
To perform internal valve inspection
between Steps 4 and 5 of the Valve
Setting Procedure remove the Dia-
phragm cover as follows:
Step 1. Close the Inverted Flare Shut-
Off Valve (R).
Step 2. Remove the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 3. Loosen the union securing the
Electric Actuation Trim and remove the
Electric Actuation Trim.
Step 4. Loosen and remove the union
between the Diaphragm Cover and the
MRA-1 Manual Reset Actuator (N) and
remove the MRA-1 Manual Reset Actu-
ator (N) subassembly.
Step 5. Remove the Diaphragm Valve
Cover hardware, then slowly remove
the Diaphragm Cover and perform
internal valve inspection. Clean the
valve interior and replace parts as
necessary.
After cleaning and inspecting valve
interior, and replacing parts as nec-
essary, reinstall the Diaphragm Cover
by completing the following steps to
assure the Diaphragm Cover Fasteners
are uniformly and securely tightened.
Step 1. With reference to Figure 1,
ensure that the Diaphragm is properly
oriented and that the proper hardware
arrangement is utilized when assem-
bling the Diaphragm Covers. The hard-
ware arrangements differ depending on
the size of the DV-5aValve.
Step 2. By first using the Long Hex
Bolts, support of the Diaphragm Cover
will be provided before installing the
Short Hex Bolts. Align Diaphragm in
proper orientation with Valve Body, and
then align Diaphragm Cover in proper
orientation with Valve Body. Hand-
tighten all fasteners.
Step 3. Using crossdraw sequence
to assure uniformity, wrench-tighten
Long Hex Bolts and Short Hex Bolts
to appropriate torque values. Repeat
crossdraw sequence two to three
times at incremental torque valves
until reaching the torque valves found
in Table B.
Step 4. Inspect to assure all Hex Bolts
are securely tightened.
Step 5. Using the union, secure the
MRA-1 Manual Reset Actuator (N) to
the Diaphragm Cover.
Step 6. Using the union, secure the
Electric Actuation Trim.
Step 7. Replace the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 8. Ensure that the unions and flare
fittings are securely tightened.
Step 9. With the Diaphragm Supply
Valve (P) closed, fully open the Inverted
Flare Shut-Off Valve (R) stainless steel
screw (approximately 1/2 in.) until resis-
tance is met so as not to break the
internal roll-pin. The internal roll-pin
stops the removal of the Inverted Flare
Shut-Off Valve (R) stainless steel screw.
Step 10. Proceed with Step 5 of the
Valve Setting Procedures section in this
data sheet.
NOTICE
If the water supply contains chemicals
which tend to attack a polyester fab-
ric-reinforced, EPDM rubber or the five
year inspection indicates a build-up of
debris within the DV-5aValve that could
affect its proper operation, then the
frequency of the internal valve inspec-
tion procedure must be appropriately
increased.
With reference to Figure 1, make
certain that the Diaphragm is correctly
oriented; otherwise, the DV-5aValve
cannot be properly set.
Under-tightening the Diaphragm Cover
Bolts can result in internal and external
leakage.
Use only TYCO replacement fasteners
as specified in Figure 1.
Do not apply adhesives, lubricants, or
other substances to the Diaphragm
Valve Body.
