Tyco DV-5 User manual

General
Description
The Model DV-5 Supervised Single In-
terlock Preaction System with Electric
Actuation (Fig. 1) utilizes automatic
sprinklers and a supplemental detec-
tion system. The supplemental detec-
tion system is typically comprised of
24 VDC heat detectors, smoke detec-
tors, manual pull stations, etc. Actua-
tion of the detection system automat-
ically operates (releases) the Model
DV-5 Deluge Valve, allowing water to
flow into the sprinkler piping system
and to be discharged from any sprin-
klers that may be open.
In accordance with the requirements
of the National Fire Protection Asso-
ciation, a preaction system employing
more than 20 automatic sprinklers is to
have the sprinkler piping automatically
supervised to monitor the overall in-
tegrity of the system. In the case of a
Supervised Single Interlock Preaction
System, a Riser Check Valve (that
does not require the use of priming
water) provides an air check so that
the system can be automatically pres-
surized with a nominal supervisory air
or nitrogen pressure of 10 psi (0,69
bar). A supervisory low pressure alarm
switch that is set to transfer its contacts
at nominally 5 psi (0,34 bar), on de-
creasing pressure, is utilized to indi-
cate whether there are any abnormal
leaks in the sprinkler system piping.
Loss of air pressure from the system
as a result of a damaged sprinkler or
broken piping will not cause the DV-5
Valve to open — the air pressure is for
supervisory alarm only.
Typically, the system designer selects
the detection components for a single
interlock preaction system that will re-
spond 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 begun to fill with
water before a sprinkler operates.
Supervised single interlock preaction
systems are generally used to protect
areas where there is danger of serious
water damage that might result from
damaged automatic sprinklers or pip-
ing. Typically, such areas include com-
puter rooms, storage areas for valu-
able 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
extinguishment by alternate suppres-
sion means, prior to a sprinkler dis-
charge. In the event the fire cannot
otherwise be extinguished, the preac-
tion sprinkler system will then perform
as the primary fire protection system.
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, such
as an O.S.&Y. gate valve or butterfly
valve (Fig. 1).
Operation of an electrical detection de-
vice such as a heat sensitive thermo-
stat, smoke detector, or electrical man-
ual control station signals the deluge
valve releasing panel to energize the
Solenoid Valve. In turn, the energized
Solenoid Valve opens to release water
from the Diaphragm Chamber faster
than it can be replenished through the
1/8 inch (3,2 mm) restriction provided
by the Model ASV-1 Automatic Shut-
Off Valve in the diaphragm supply con-
nection (Item 5 - Fig. 2A, also de-
scribed in Technical Data Sheet
TFP1384). This results in a rapid pres-
sure drop in the Diaphragm Chamber
to 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
pilot chamber of the Model ASV-1
Automatic Shut-Off Valve (Item 5 - Fig.
2A) becomes pressurized and the
ASV-1 automatically shuts off the dia-
phragm chamber supply flow to the
DV-5 Diaphragm Chamber. Shutting
off the diaphragm chamber supply flow
prevents the DV-5 Diaphragm Cham-
ber from becoming re-pressurized,
thereby preventing inadvertent closing
oftheDV-5duringafire(asmaybethe
case should the Solenoid Valve be-
come de-energized after its initial op-
eration).
WARNING

Valve Trim
The Supervised Single Interlock Pre-
action System With Electric 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 Supervisory
Switch
•Waterflow Pressure Alarm Switch
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.
Detection System
In order for a single interlock preaction
system to be hydraulically calculated
as a wet pipe system, as opposed to a
dry pipe sprinkler system, the detec-
tion system must be designed to oper-
ate sooner than the automatic sprin-
klers on the sprinkler piping.
The Supervised Single Interlock Pre-
action System With Electric Actuation
Trim provides for electric operation of
the DV-5 Valve by a detection system
consisting of electrical devices such as
heat sensitive thermostats, smoke de-
tectors, and/or electric manual pull sta-
tions. Information on the various types
of separately ordered Solenoid Valves
that may be used with this trim pack-
age is given in Technical Data Sheet
TFP2180. Nominal installation dimen-
sions for the Supervised Single Inter-
lock Preaction System With Electric
Actuation Trim are shown in Figure 3.
NOTES
Approval by Factory Mutual is contin-
gent on the use of an FM Approved
24VDC Solenoid Valve (P/N 52-287-1-
024 or P/N 52-287-1-124). FM only
approves solenoid valves for use in
non-hazardous locations.
Consult with the Authority Having Ju-
risdiction regarding installation criteria
pertaining to electric actuation cir-
cuitry.
The Supervised Single Interlock Pre-
action System With Electric Actuation
Trim is provided with a Model ASV-1
Automatic Shut-Off Valve (Item 5 - Fig.
2A); consequently, the release circuit
of the releasing panel need only pro-
vide the standard ten minutes of alarm
condition intended to energize the So-
lenoid Valve. After the ten minute du-
ration, should the Solenoid Valve be-
come de-energized and close
(especially while operating under bat-
tery back-up), the Automatic Shut-Off
Valve will have already automatically
closed thereby preventing the DV-5
Diaphragm Chamber from becoming
re-pressurized and preventing an in-
advertent closing of the DV-5 during a
fire event.
System Air Pressure Requirements
The supervisory air (nitrogen) pres-
sure is to be 10 plus or minus 2 psi
(0,69 plus or minus 0,07 bar). The use
of a higher supervisory pressure is
subject to approval by the Authority
Having Jurisdiction, and it should be
understood that the use of a higher
supervisory pressure may increase
water delivery time. The use of a lower
supervisory pressure may prevent
clearing the alarm of the Supervisory
Low Pressure Alarm Switch (Item P3 -
Fig. 2A), which is factory set to alarm
at5plusorminus1psi(0,34plusor
minus 0,07 bar) on decreasing pres-

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.
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 are ca-
pable of preventing 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
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 such
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 and set for
10 plus or minus 2 psi (0,69 plus or
minus 0,14 bar).
Step 10. A desiccant dryer, when re-
quired for the supervisory air supply, is
to be installed between a drip leg and
theModelAMD-1AirMaintenanceDe-
vice or between the Model G16AC812
Automatic Supervisory Air Supply and
the Preaction Trim.
Step 11. The Supervisory Low Pres-
sure Alarm Switch is to be wired to the
supervisory alarm initiating circuit of
an alarm panel.
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 (Item 4, Fig. 2A)
is to be temporarily replaced with a 1/2
inch NPT plug, the 3/32 inch Vent Fit-
ting (16 - Fig. 2A) is to be temporarily
replaced with a 1/4 inch NPT plug, and
the Diaphragm Cover Bolts must be
uniformly and securely tightened
using a cross-draw sequence. After
tightening, double-check to make cer-
tain that all of the Diaphragm Cover
Bolts are securely tightened.
Valve Setting
Procedure
Steps 1 through 12 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 Su-
pervisory 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.
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. 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 7. Open the Diaphragm Chamber
Supply Control Valve and allow time for
full pressure to build up in the Dia-
phragm Chamber.
Step 8. Operate (open) the Manual
Control Station to vent trapped air from
the Diaphragm Chamber. If necessary,
Page 11 of 14
TFP1420

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 9. Inspect the drain connections
from the Manual Control Station and
the Solenoid Valve. Any leaks must be
corrected before proceeding to the
next step.
Step 10. Verify the ability for the DV-5
Diaphragm to hold pressure as fol-
lows:
With the diaphragm chamber pressur-
ized per Step 8, temporarily close the
Diaphragm Chamber Supply Control
Valve, and monitor 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 11. Replace operated automatic
sprinklers on the system piping and
then open the Supervisory Air Supply
Control Valve and allow the system to
automatically re-establish its nominal
air pressure of 10 psi (0,69 bar). 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.
NOTE
In order to prevent the possibility of a
subsequent operation of an over-
heated solder type automatic sprin-
kler, any solder type automatic sprin-
klers that were possibly exposed to a
temperature greater than their maxi-
mum rated ambient must be replaced.
Step 12. Slowly open the Main Control
Valve. Close the Main Drain Valve as
soon as water discharges from the
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.
NOTES
Some of the procedures outlined in
this section will result in operation of
the associated alarms. Consequently,
notification must first be given to the
owner and the fire department, central
station, or other signal station to which
the alarms are connected.
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 no-
tified.
Annual Operation Test Procedure
Proper operation of the DV-5 Valve
(i.e., opening of the DV-5 Valve as dur-
ing a fire condition) must be verified at
least once a year as follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps.
•Close the Main Control Valve. Open
the Main Drain Valve.
•Open the Main Control Valve one
turn beyond the position at which
water just begins to flow from the
Main Drain Valve.
•Close the Main Drain Valve.
Step 2. Test the deluge releasing
panel in accordance with the manufac-
turer’s instructions to energize the So-
lenoid Valve.
NOTE
Be prepared to quickly perform Steps
3, 4, and 5, if water must be prevented
from flowing beyond the riser.
Step 3. Verify that the DV-5 Valve has
tripped, as indicated by the flow of
water into the system.
Step 4. Close the system’s Main Con-
trol Valve.
Step 5. Close the Diaphragm Cham-
ber Supply Control Valve and the Su-
pervisory Air Supply Control Valve.
Step 6. Reset the DV-5 Deluge Valve
in accordance with the Valve Setting
Procedure.
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.
Quarterly Solenoid Valve Test
Procedure For Electric Actuation
Proper operation of the Solenoid Valve
for electric actuation must be verified
at least quarterly as follows:
Step 1. Close the Main Control Valve.
Step 2. Open the Main Drain Valve.
Step 3. Test the deluge releasing
panel in accordance with the manufac-
turer’s instructions to energize the so-
lenoid valve.
Step 4. Verify that the flow of water
from the Solenoid Valve drain connec-
tion increases to a full flow.
Step 5. Verify that the Diaphragm
Chamber pressure has decreased to
below 25% of the water supply pres-
sure.
Step 6. Reset the electric detection
Page 12 of 14 TFP1420

system in accordance with the manu-
facturer’s instructions to de-energize
the solenoid valve. Check the Solenoid
Valve drain for leaks. Any leaks must
be corrected before proceeding to the
next step.
Step 7. Slowly open the Main Control
Valve. Close the Main Drain Valve as
soon as water discharges from the
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.
NOTE
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.
Quarterly Supervisory Low Pres-
sure Alarm Test Procedure
Proper operation of the Supervisory
Low Pressure Alarm Switch must be
performed quarterly as follows:
Step 1. Crack open the System Main
Drain Valve for the Riser Check Valve
(Item P7, Figure 2A) to slowly relieve
supervisory air pressure from the sys-
tem. Verify that the Supervisory Low
Pressure Alarm Switch is operational
and that the low pressure set point is
approximately 5 psi (0,34 bar).
Step 2. Close the System Main Drain
Valve (Item P7, Figure 2A) and allow
the system supervisory pressure of 10
plus or minus 2 psi (0,69 plus or minus
0,14 bar) to be automatically re-estab-
lished. The Supervisory Low Pressure
Alarm Switch should return to its “nor-
mal” condition.
Pressure Relief Valve Maintenance
Over pressurization of the system pip-
ing with air will result in the opening of
the Pressure Relief Valve (Item P4,
Fig. 2A). If the Relief Valve continues
to bleed air after the system pressure
has been reduced to its normal super-
visory pressure range of 10 plus or
minus 2 psi (0,69 plus or minus 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 Relief Valve to allow a
full flow of air through the Relief Valve,
and then release the ring to allow the
Relief Valve to snap closed. Repeat the
cleaning procedure as necessary
