General
Description
The TYCO DV-5aAutomatic Water
Control Valves are diaphragm type
valves that can be used in double inter-
lock preaction re protection systems.
When properly trimmed, the double
seat design of the DV-5aValve also
provides actuation of re 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-5aValves are offered with the
DV-5aValve and separately ordered
semi-assembled trim shown in Figures
6 and 7, or, for ease of installation, with
DV-5aValve completely trimmed with or
without a System Main Control Valve.
Double interlock preaction systems are
designed for use in applications, such
as refrigerated areas, requiring the
maximum degree of protection against
inadvertent ooding of the sprinkler
system piping. In order for a double
interlock preaction system to automat-
ically activate, two independent events
must occur. First, the electric detection
system must operate, and secondly,
an automatic sprinkler on the system
piping must operate. Typically, the
electric detection system is designed to
operate before any automatic sprinkler.
Operation of just the electric detection,
or just the opening of a sprinkler will
not allow the DV-5aValve to open and
permit water to ow into the normally
dry sprinkler system piping. However,
operation of just the electric detec-
tion system or the opening of a sprin-
kler (loss of system air pressure) will
result in a supervisory alarm to notify
the building occupants of a condition

needing attention so as to avoid inad-
vertent ooding of the system piping.
A solenoid valve is used in the Elec-
tric/Electric Actuation to hold the DV-5a
Valve closed by locking pressure in the
diaphragm chamber of the DV-5aValve.
In the event of a re, Zone 1 of a releas-
ing panel is initiated by a re detection
or electric manual pull station, and
Zone 2 of the releasing panel is initi-
ated by a low pressure alarm switch
triggered by loss of system air pres-
sure due to the opening of an auto-
matic sprinkler. Initiating of Zone 1 and
2 results in opening the solenoid valve
to operate the DV-5aValve.
NOTICE
The DV-5aValves described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
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.

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 of a solenoid valve for Electric/
Electric Actuation (see Figure 4) trips the
Model MRA-1 Manual Reset Actuator.
Tripping the MRA-1 releases water from
the DV-5aDiaphragm Chamber faster
than it can be replenished through the
1/8 in. (3,2 mm) restriction located in
the diaphragm chamber supply con-
nection. 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 Actua-
tor opens to constantly vent the DV-5a
Diaphragm Chamber to "hydraulically
latch" the DV-5ain the tripped position
until manually reset.

section for additional information.

System Design Considerations
Because a double interlock preac-
tion system requires time for a drop in
system air pressure to occur (concur-
rently with the response time for the
separate re detection system) before
it will allow water to enter the system
piping, this system has characteristics
similar to a dry pipe sprinkler system.
Therefore, the system design con-
siderations 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
capacities of 500 gallons (1890 liters)
or more; and, prohibition of gridded
system piping.
As an option, the DV-5aDouble Inter-
lock Preaction System with Electric/
Electric Actuation may be equipped
with the Model QRS Electronic Accel-
erator to reduce the time to valve actu-
ation following the operation of the
electric detection system and one or
more automatic sprinklers. Refer to
Technical Data Sheet TFP1100 for
details regarding installation require-
ments and pressure ratings.
Note: Use of the Model QRS Electronic
Accelerator can permit system volumes
of 750 gallons (2840 Liters) without
applying the minimum one minute
water delivery time.
In order to readily perform the System
Inspection Procedure described in
the Care and Maintenance section,
it is recommended that a System
Shut-Off Valve be installed above the
DV-5aValve, as shown in Figure 4. The
System Shut-Off Valve should be a
listed or approved (as appropriate) indi-
cating valve with a supervisory switch
to monitor the normally open position.
Detection System
The Double Interlock Preaction System
With Electric/Electric Actuation Trim
provides for electric operation of the
DV-5aValve by a detection system
consisting of electrical devices such
as heat sensitive thermostats, smoke
detectors, and/or electric manual pull
stations. Information on the various
types of separately ordered Solenoid
Valves that may be used with this trim
package is given in Technical Data
Sheet TFP2180. Nominal installation
dimensions for the Double Interlock
Preaction System With Electric/Electric
Actuation Trim are shown in Figure 7.
The cross-zone deluge valve releas-
ing panel (automatic control unit)
with battery back-up, re detection
devices, manual pull stations, and sig-
naling devices, that are utilized with the
Double Interlock Preaction System with
Electric/Electric Actuation must be UL
Listed, ULC Listed, C-UL Listed, or FM
Approved, as applicable.
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 authority having
jurisdiction 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 prevent-
ing the DV-5aDiaphragm Chamber
from becoming re-pressurized, and
preventing an inadvertent closing of
the DV-5aduring a re event.
WARNING
If the delay between electric actua-
tion and subsequent sprinkler activa-
tion is anticipated to be greater then
10 minutes, adjust the battery back-up
calculation accordingly. Inadequate
battery back-up may result in failure of
the system to operate in the event of a
fire during a power failure.
Releasing Circuit
The recommened arrangement is to
equip the releasing circuit with a Potter
RCDS-1 Releasing Circuit Switch, or
equivalent. The RCDS-1 provides for a
temporary disconnect (de-energized) of
the Solenoid Valve during Step 9 of the
Valve Resetting Procedure.
System Air Pressure Requirements
The recommended system air pres-
sure for the Double Interlock Preaction
System with Electric/Electric Actuation
is nominally 15 psi (1,0 bar), irrespective
of the water supply pressure. The use
of a higher system air pressure may or
may not adversely affect water deliv-
ery time, and the use of a lower system
air pressure may prevent clearing the
alarm of the Low Pressure Switch on
increasing pressure. The Low Pressure
Switch is eld set to alarm at nominally
12 psi (0,8 bar) on decreasing pres-
sure when using a nominal system air
pressure of 15 psi (1,0 bar). It is recom-
mended that the system air pressure
be maintained by either of the follow-
ing methods:
• A maximum 200 psi (13,8 bar) plant
air supply in combination with the
Model AMD-1 Air Maintenance
Device described in Technical Data
Sheet TFP1221
• A maximum 3000 psi (206,9 bar)
nitrogen cylinder in combination with
the Model AMD-3 Nitrogen Mainte-
nance Device described in Technical
Data Sheet TFP1241
NOTES:
It is recommended that the pressure
maintenance device be of a type that
maintains a constantsystem pressure, i.e.,
a pressure maintenance device that utilizes
a pressure regulator versus a pressure
switch (e.g., the AMD-1 or AMD-3). Use
of a pressure switch operated pressure
maintenance device with a cut-in/cut-
out differential may result in a delay in
the operation of the system due to a fire,
because of the cut-out pressure being
higher than the recommended nominal
system air pressure.
The dew point of the air or nitrogen
supply, for a system exposed to freezing
conditions, must be maintained below the
lowest ambient temperature to which the
system piping will be exposed. Introduction
of moisture into the system piping can
create ice build up which could prevent
proper operation of the system.
The Air Pressure Relief Valve is typi-
cally eld set to crack open at a pres-
sure of about 20 psi (1,4 bar) when
using a nominal system air pressure of
15 psi (1,0 bar).
Installation
The TYCO DV-5aValve 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-5aValves
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-5aValve
from functioning properly, as well as
void approvals and the manufacturer’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, ttings, 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-5aValve must be
trimmed in accordance with one of the
trim illustrations 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
orderedelectronicallysupervisednormally
open valve.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc., are installed with the ow
arrows in the proper direction.
Step 4. Drain tubing to the Drip Funnel
must be installed with smooth bends
that will not restrict ow.
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. An Inspector’s Test Connection
is to be located on the sprinkler system
at the most hydraulically demanding
location.
Step 9. A suitable automatic air (nitro-
gen) supply, as described in the appli-
cable Electric/Electric Actuation
sub-section, is to be installed in accor-
dance with the applicable technical
data sheet. The minimum air pressure
is to be in accordance with the refer-
enced sub-sections.
Step 10. A desiccant dryer, when spec-
ied, is to be installed between a drip
leg and the Air Maintenance Device.
Step 11. The Low Pressure Switch on
falling pressure in the Electric/Electric
Actuation is to be adjusted so that the
low pressure alarm setting is set at
3 psi (0,21 bar) below the system air
pressure.
Step 12. Unused Pressure Alarm
Switch connections must be plugged.
Step 13. The Pressure Relief Valve on
rising pressure is to be at 5 psi (0,34 bar)
higher than the required system air
pressure, or be reset in accordance
with the requirements of the authority
having jurisdiction.
To reset the Pressure Relief Valve, rst
loosen the jam nut and then adjust the

TFP1466
Page 8 of 18
cap accordingly, clockwise for a higher
pressure setting or counter clockwise
for a lower pressure setting. After ver-
ifying the desired pressure setting,
tighten the jam nut.
Step 14. Conduit and electrical con-
nections are to be made in accordance
with the applicable standards of the
approval agency.
Step 15. 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
the Care and Maintenance section for
torque specications.
Valve Setting
Procedure
Perform Steps 1 through 20 when ini-
tially setting the TYCO DV-5aValve,
after an operational test of the re pro-
tection system, or after system opera-
tion due to a re. See Figure 8.
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P) and Air Supply Valve (S).
Step 3. 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.
NOTICE
Do not open the Inspector’s Test Con-
nection and auxiliary drains if reset-
ting after a system test; otherwise,
system air pressure will be relieved
unnecessarily.
Step 4. Depress the plunger of the
Automatic Drain Valve (F) to verify that
it is open.
Step 5. Clean the Diaphragm Supply
Strainer (Q) by removing the clean-
out plug and strainer basket. The Dia-
phragm Supply Strainer (Q) may be
ushed out by momentarily opening
the Diaphragm Supply Valve (P).
Step 6. Inspect for and clear all ice
plugs where system piping has been
exposed to freezing conditions and
when there has been a ow of water
into the system.
Step 7. Replace all damaged or oper-
ated sprinklers. Replacement sprinklers
must be of the same type and tempera-
ture rating as those that operated.
NOTICE
In order to prevent the possibility of a
subsequent operation of an overheated
solder type sprinkler, any solder type
sprinklers possibly exposed to a tem-
perature 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. De-energize the Solenoid Valve
(V) via the Potter RCDS-1 Releasing
Circuit Disable Switch, or equivalent.
Step 10. 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 11. After allowing water to ow out
of the Manual Reset Actuator (N) drain
tube until aerated water ceases to dis-
charge, reset the Manual Reset Actua-
tor (N) by pressing the Reset Knob and
hold until water stops owing 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-5aDia-
phragm Chamber.
Step 12. Inspect the actuation device
drain connections. Any leaks must be
corrected before proceeding to the
next step. Electric/Electric Actuation
drain connection to be inspected are
from the Manual Control Station (M)
and Solenoid Valve (V) shown in Figure
4.
Step 13. Verify the ability for the DV-5a
Diaphragm to hold pressure as follows:
• With the diaphragm chamber pres-
surized per Step 11, temporarily
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 Dia-
phragm Supply Valve (P) and pro-
ceed to the next step.
Step 14. Open the Air Supply Valve
(S) and allow the system to automati-
cally re-establish its nominal system
air pressure. Observe the Automatic
Drain Valve (F) for leaks. If there are
leaks, determine/correct the cause of
the leakage problem.
• Nominal system air pressure for Elec-
tric/Electric Actuation is typically 15
psi (1,0 bar).
Step 15. Open the System Shut-Off
Valve (X), as will be the case when
resetting a system after performing an
operational test.
Step 16. Reset the electric detection
system in accordance with the man-
ufacturer's instructions. After setting
the releasing panel, return the Potter
RCDS-1 to "green light - releasing
circuit system normal".
Step 17. 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 18. Close the hinged cover on the
Manual Control Station (M) and insert a
new break rod in the small hole through
the top of the enclosing box.
Step 19. Fully open the System Main
Control Valve (B).
Step 20. After setting a re protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.

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.
It is recommended that the System
Inspection Procedure be performed
at least semi-annually by a quali-
ed Inspection Service. The Double
Interlock Preaction System Inspec-
tion Procedure may be followed in lieu
of performing any of the operational
tests recommended in the Technical
Data Sheets for the 24 VDC Solenoid
Valve and Model MC-1 Manual Control
Station.
It is recommended that the individuals
responsible for the care and mainte-
nance of the Double Interlock Preaction
System develop a working understand-
ing of the system, in general, prior to
performing inspection and/or mainte-
nance procedures. These instructions,
as well as individual instructions for
the 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 System.
Refer to the manufacturer’s instructions
and NFPA 25 for care and maintenance
procedures for all other devices (e.g.,

tion Procedure or Waterflow Alarm
Test Procedure, which will result in
operation of alarms, notify the proper
authorities and all personnel who may
be affected.
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 waterow alarm, open the
Alarm Test Valve (G), which will allow a
ow of water to the Waterow 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).

Electric/Electric Actuation
System Operation Procedure
Proper operation of the DV-5aValve for
both opening of the DV-5aValve in a
re condition, or not opening the DV-5a
Valve in a non-re condition, must be
veried as follows:
Step 1. Close the System Main Control
Valve (B) and then open the Main Drain
Valve (D).
Step 2. Manually operate Zone 1 of
the Releasing Panel, and verify the
following:
• The operation of the Releasing Panel
and its associated alarms
• That there is no leakage from the
Solenoid Valve (V)
NOTE: During this procedure, the Solenoid
Valve (V) should remain closed and the
DV-5aDeluge Valve Diaphragm Chamber
should remain pressurized.
This procedure is used to verify that the
DV-5aDeluge Valve will remain set if the
electric detectionsystem (Zone1) operates
but the sprinkler system (Zone 2) remains
in its normally pressurized condition.
Step 3. Restore the electric re detec-
tion system to a normal condition in
accordance with the manufacturer’s
instructions.
Step 4. Open the Inspector’s Test Con-
nection to relieve system air pressure,
and verify the following:
• That the Low Air Pressure Alarm
Switch (U) and Zone 2 of the Releas-
ing Panel, as well as its associated
alarms, operate properly. The Low
Air Pressure Alarm Switch (U) should
operate at the previously established
pressure (see Installation section,
Step 9).
• That there is no leakage from the
Solenoid Valve (V).
Step 5. Close the Inspector’s Test
Connection.
NOTE: During this procedure, the Solenoid
Valve (V) should remain closed and the
DV-5aValve Diaphragm Chamber should
remain pressurized.
This procedure is used to verify that the
DV-5aValve will remain set if the Low
Air Pressure Alarm Switch (U) (Zone 2)
operates due to loss of system air pressure
and the electric detection system (Zone 1)
remains in a normal condition.
Step 6. Restore the electric re detec-
tion system to a normal condition in
accordance with the manufacturer’s
instructions after the system air pres-
sure has automatically been restored
to normal.
Step 7. Close the System Shut-Off
Valve (W) after the system air pressure
has been restored to normal.
Step 8. Open the System Main Control
Valve (B) one turn beyond the position
at which water just begins to ow from
the Main Drain Valve (D).
Step 9. Close the Main Drain Valve (D).
Step 10. Close the Air Supply Valve (S).
Step 11. Manually operate Zone 1 of
the Releasing Panel, and then operate
Zone 2 of the Releasing Panel by par-
tially opening the System Drain Valve
(E) to relieve air pressure at the Low Air
Pressure Alarm Switch (U), and verify
the following:
• That the DV-5aValve operates as is
indicated by a discharge of water
from the System Drain Valve (E) and
the Automatic Drain Valve (F). The
Automatic Drain Valve (F) may or may
not close depending on the ow past
the partially open System Main Con-
trol Valve (B)
• That the Model MRA-1 Manual Reset
Actuator (N) has operated as is indi-
cated by water discharging into the
Drip Funnel from the 1/2 in. drain
tube connected to the Model MRA-1
Manual Reset Actuator (N)
• That the Waterow Pressure Switch
(C) and its associated alarms prop-
erly operate
• That the Water Motor Alarm, if appli-
cable, properly operates
NOTE: This procedure simulatesautomatic
system operation upon both electric
detection and loss of system air pressure.
Internal Valve Inspection
Once every ve 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/Electric Actuation Trim and
remove the Electric/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 rst 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/Electric Actuation Trim.
Step 7. Replace the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).

TFP1466
Page 16 of 18
Step 8. Ensure that the unions and are
ttings 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 fabric-
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 inspection 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.

1. Close System Main Con trol Valve (B), Diaphragm Supply Valve (P), and Air S upply Control
Valves (X) and ( Y).
2. Open Main Drain Valve (D), System D rain Valve (E), and all auxiliar y drains in system. Also,
remove plug from Air Sup ply Strainer (W ) to drain any water and ensu re it is clean and free
of debris. Close aux iliary drain valves , System Drain Valve (E), and reas semble Air Suppl y
Strainer (W ) after water stops dis charging. Leave Main Dra in Valve (D) open.
3. Ensure Pressure Ga uge Valves and Alarm Contro l Valve (H), as applicable, are open.
4. Depress plunge r of Automatic Drain Valve (F) to ver ify it is open.
5. Clean Diaphra gm Supply Strainer (Q). Flus h strainer by opening the D iaphragm Supply
Valve ( P).
6. Replace operate d automatic sprinkler s on system piping.
7. Reset D V-5AValve Releasing Panel in accordance with manufacturer instructions.
8. Re-estab lish system air pressu re to reset Model DP-1 Dry Pilot Actua tor (T) by openi ng Air
Supply Control Valve (X ). Do not open Air Supp ly Control Valve (Y) a t this time. Observe Dr y
Pilot Actuator (T ) air pressure on D ry Pilot Gauge (Z ).
9. Open Manual Cont rol Station (M), then open D iaphragm Supply Valve (P). After a erated
water stops discharging f rom Manual Control St ation (M) drain tube, slowly c lose operating
lever. Do not close hinged cover at this time.
10. After aera ted water stops discharging, re set Manual Reset Ac tuator (N) until water stops
owing from its drain tub e and pressure reac hes approximately 15 psi (1,0 bar) on Diaphragm
Gauge (K).
11. With diaphragm chamber pressurized, temporarily close Diaphragm Supply Valve (P), and
observe Diap hragm Gauge (K ) for a drop in pressure. If p ressure drop is noted, re place DV-5A
Diaphragm and co rrect any leaks befo re proceeding.
12. If Diaph ragm Gauge (K) i ndicates no drop in pres sure, re-open Di aphragm Supply Valve
(P) and procee d.
13. Open Air S upply Control Valve (Y ) to pressurize system pip ing.
14. Parti ally open System Main Co ntrol Valve (B). Slowly close Main Drai n Valve (D) as water
discharges from M ain Drain Valve (D). Obser ve Automatic Drain Valve (F) for le aks. If there
are leaks, correct the leakage problem.
15. Close hinge d cover of Manual Control St ation (M) and inser t new break rod in small ho le
through the top of the enclosing box.
16. Open System M ain Control Valve (B).
17. After sett ing re protection system, no tify proper autho rities and advise tho se responsible
for monitoring proprietary and/or central station alarms.
Waterflow Alarm Test Procedure
1. Open Alarm Test Valve (G), allowing water to ow to Waterow Press ure Switch (C) and/or
Water Motor Alarm. Close A larm Test Valve (G) when test is completed.
2. Depress plunge r on the Automatic Drain Valve (F ) to drain alarm line.
Solenoid Valve Test Procedure For Electric Actuation
1. Close System Main Co ntrol Valve (B) and open Main Drai n Valve (D).
2. Test deluge releasing panel in a ccordance with manu facturer’s instructions to en ergize
the Solenoid Valve (R).
3. Verify that water is owing fro m Solenoid Valve (R) drain conn ection.
4. Verify Diaphrag m Chamber pressure has decrea sed to below 25% of water supp ly pressure.
5. Reset electric d etection system in accord ance with manufacture r’s instruc tions to de-ener-
gize Solenoid Valve (R). Water should top draining from Solenoid Valve (R) but remain draining
from Manual Rese t Actuator (N).
