General
Description
The TYCO RAPID RESPONSE Model
RSV-1 Residential Shut-Off Valves
are intended for use in dual-purpose
residential water supply piping that
serves both domestic and residential
re protection sprinkler system needs.
The 1 Inch (DN25) Valve is intended
for NFPA 13D system needs, whereas
the 2 Inch (DN50) Valve is intended for
systems designed in accordance with
either NFPA 13D or NFPA 13R.
When a re sprinkler operates, the
Model RSV-1 Residential Shut-Off
Valve automatically shuts off water
ow to the domestic system and di-
verts the available water supply to the
re sprinkler system. Consequently,
when the Model RSV-1 Valve is uti-
lized, the system designer does not
need to add the domestic ow de-
mand to the re sprinkler system ow
demand, as would otherwise be re-
quired by NFPA 13R.
Consider use of the Model RSV-1
Residential Shut-Off Valve when either
the water supply cannot adequately
provide for both the domestic design
demand and the re sprinkler ow de-
mand, or it is necessary to increase
the effectiveness of the re sprinkler
system by automatically shutting off
the domestic ow.
The Model RSV-1 Residential Shut-
Off Valve maximizes the effective use
of an existing water supply. Therefore,
in areas with limited water supplies, it
may eliminate the need to add costly
pumps, pressurized reservoirs, or elec-
trically operated domestic shut-off
valves. The Model RSV-1 Valve has a
built-in check valve in the re sprinkler
system outlet that eliminates the need
for a separate check valve. Also, the
Model RSV-1 Valve automatically re-
sets, thereby eliminating the need for
valve disassembly after a re sprinkler
system test or operation.
NOTICE
The Model RSV-1 Residential Shut-Off
Valves 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, in addition to the standards
of any authorities having jurisdiction.
Failure to do so may impair the integrity
of this device.
The owner is responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.

Design Criteria
The TYCO RAPID RESPONSE Model
RSV-1 Residential Shut-Off Valve
must be installed vertically with the
Water Supply Port at the bottom, the
Fire Sprinkler Port at the top, and the
Domestic Port at the side (Figures 7
and 8). Figure 1 shows the typical in-
stallation arrangement. Refer to the
Installation section for additional de-
sign considerations.
Local regulations concerning pub-
lic water supplies may require a
backow prevention device. The de-
sign of the Model RSV-1 Residential
Shut-Off Valve anticipates that the
backow prevention device will be
located in the water supply upstream
of the Model RSV-1 Valve as shown
in Figure 1. Should local regulations
require the backow prevention de-
vice to be located in the re sprinkler
line downstream of the Model RSV-1
Valve, a by-pass per Figure 2 must be
installed.
NOTICE
Do not install a check valve between the
Model RSV-1 Residential Shut-Off Valve
and the fire sprinklers unless a by-pass
per Figure 2 is installed. Installing a by-
pass disables performance of the Model
RSV-1 Valve as a check valve.
Water Supply Requirements
• 1 Inch (DN25) Valve
In order for the 1 Inch (DN25) Model
RSV-1 Valve to operate automati-
cally upon sprinkler operation, the
re sprinkler system from the water
main to the most hydraulically re-
mote sprinkler must be designed to
provide a minimum single sprinkler
ow of 12.5 GPM (47,3 LPM) when
the supply pressure at the main is at
its minimum expected value.
The minimum single sprinkler ow
rate of 12.5 GPM (47,3 LPM), re-
quired for use with the 1 Inch (DN25)
Model RSV-1 Valve, does not take
precedence over any more hydrau-
lically demanding single sprinkler
ow rate specied for the residential
sprinklers in use.
When performing hydraulic design
calculations for the re sprinkler
system, you need not account for
the trickle ow through the 1 Inch
(DN25) Model RSV-1 Valve By-
Pass Restriction into the domestic
system.
For the 1 Inch (DN25) Model RSV-1
Valve, the maximum water supply
service line is 1 inch (DN25).
• 2 Inch (DN50) Valve
In order for the 2 Inch (DN50) Model
RSV-1 Valve to operate automati-
cally at sprinkler activation, the re
sprinkler system from the water
supply main to the most hydrauli-
cally remote sprinkler must be de-
signed to provide a minimum single
sprinkler ow of 8 GPM (30,5 LPM)
when the water supply pressure at
the water supply main is at its mini-
mum expected value.
The minimum single sprinkler ow
rate of 8 GPM (30,5 LPM), required
for use with the 2 Inch (DN50) Model
RSV-1 Valve, does not take prece-
dence over any more hydraulically
demanding single sprinkler ow rate
specied for the residential sprin-
klers in use.

Operating
Principles
When a re sprinkler activates dur-
ing domestic usage, the TYCO RAPID
RESPONSE Model RSV-1 Residential
Shut-Off Valve automatically shuts off
ow to the domestic system and di-
verts the available water supply to the
re sprinkler system, thereby eliminat-
ing a reduced ow condition in the
sprinkler system that might otherwise
be caused by possible signicant do-
mestic water usage.
When the Model RSV-1 Valve is in the
normal standby position as shown in
Figures 7 and 8, the Piston Assembly,
assisted by its Spring, is in the down
position. With the Piston Assembly in
the down position, the Fire Sprinkler
Seal permits the Model RSV-1 Valve
to perform as a conventional check
valve. Also, with the Piston Assembly
in the down position, water is avail-
able on demand through the Domestic
Flow Passage and out the Domestic
Port.
Upon operation and with a minimum
design water ow (e.g., 12.5 GPM (47,3
LPM) for the 1 inch Valve or 8 GPM
(30,5 LPM) for the 2 Inch Valve) to the
automatic residential re sprinkler
system, the Piston Assembly moves
upward. With the Piston Assembly in
the up position, any water ow to the
Domestic Port is diverted to the Fire
Sprinkler Port.
The contours of the Piston Assembly
are specically congured to minimize
its upward movement except under
the level of sustained re sprinkler
system ow resulting from operation
of one or more re sprinklers. How-
ever, because most re sprinkler sys-
tems contain air pockets, the Piston
Assembly tends to move momentarily
upward when there is a surge in sup-
ply pressure.
The momentary opening and re-clos-
ing of the Piston Assembly at the Fire
Sprinkler Line Seal traps a portion
of the pressure increase within the
re sprinkler system. Trapped pres-
sure increases within the re sprinkler
system help to prevent a subsequent
surge in the supply pressure from
causing the water-ow detector to sig-
nal a false alarm (unless a by-pass is
installed per Figure 2).

As indicated above, domestic system
usage can reduce the pressure avail-
able to the re sprinkler system. How-
ever, when utilizing the Model RSV-1
Valve, you do not need to include ad-
ditional hydraulic ow of the domestic
system, when otherwise required by
NFPA standards (NFPA 13R), to deter-
mine the minimum possible residual
(owing) pressure available to the re
sprinkler system.
For operation of the Model RSV-1 Res-
idential Shut-Off Valve, you need only
design the re sprinkler system from
the water supply main to the most hy-
draulically remote sprinkler. Domestic
ow does not require consideration.
As long as the single sprinkler ow
is equal to or greater than 12.5 GPM
(47,3 LPM) for the 1 Inch Valve or 8
GPM (30,5 LPM) for the 2 Inch Valve
when the supply pressure at the main
is at its minimum expected value,
the Model RSV-1 Valve automatically
shuts off the domestic ow.
After the Piston Assembly has moved
to the full up position, only a small
amount of water is permitted to trickle
through the Internal By-Pass Restric-
tion to the Domestic Port (Figures 7
and 8). The trickle ow through the
Internal By-Pass Restriction permits
the Model RSV-1 Valve to reset auto-
matically after a sprinkler operation or
test without draining the re sprinkler
system.
When the Domestic Control Valve is
closed, the Internal By-Pass Restric-
tion allows the Supply and Domestic
Port pressures to equalize and the
Piston Assembly to move back down
to the standby position.
The maximum ow rate through the
Internal By-Pass Restriction, when
the Model RSV-1 Valve is in the op-
erated position, is less than 1/4 GPM
(0,9 LPM) for a typical residual (ow-
ing) pressure of 40 psi (2,8 bar) at the
inlet. Consequently, when performing
hydraulic design calculations for the
re sprinkler system, you do not need
to consider trickle ow through the
Model RSV-1 Valve Internal By-Pass
Restriction into the domestic system.

Installation
NOTICE
A fire sprinkler water supply connection
to a public water supply is usually subject
to local regulations concerning metering
and backflow prevention requirements.
Consult with the local water authorities
concerning local requirements that
may apply to the arrangement of these
components in the fire sprinkler system
water supply.
Figure 1 illustrates a typical installation
arrangement using the TYCO RAPID
RESPONSE Model RSV-1 Residential
Shut-Off Valve. The arrangement may
need to be modied to meet the re-
quirements of the authority having ju-
risdiction. However, the Model RSV-1
Valve must be installed in accordance
with the following criteria.
Note: For the 1 Inch (DN25) Valve, the
maximum water supply service line is
1 Inch (DN25).
1. Ensure that the water supply to the
Model RSV-1 Valve is free of contami-
nants and particles of a size greater
than 1/8 inch (3,2 mm).
2. Install the Model RSV-1 Valve verti-
cally with the Supply Port at the bot-
tom, the Fire Sprinkler Port at the top,
and the Domestic Port at the side.
Ensure that the arrows cast on the
Body point in the direction of ow.
A suitable clamp along the water
supply riser piping is recommended
to provide support for the weight of
the Model RSV-1 Valve.
3.
Place a Domestic Control Valve be-
tween the Model RSV-1 Valve and
the domestic system. Position the
inlet to the Domestic Control Valve
within 12 inches of the Domestic Port
of the Model RSV-1 Valve.
4.
The Drain and Flow Test Connection
(Figure 1) is recommended to be a
minimum 1/2 inch (DN15) size for
systems per NFPA 13D, and it must
be a minimum 1 inch (DN25) size for
systems per NFPA 13R.
5.
Install an Alarm Test Connection
with a test orice equal to or less
than the smallest K-factor sprinkler
in the system downstream of the
Waterow Detector.
6.
Apply pipe-thread sealant sparingly
only to the male pipe threads that are
to be assembled to the three ports of
the Model RSV-1 Valve. The use of a
non-hardening pipe-thread sealant
such as TEFLON is recommended.
Valve Setting
Procedure
Perform steps 1 through 9 when initial-
ly lling the re sprinkler and domestic
system piping with water or after a re
sprinkler operation (Figure 1).
1. Close the Main Control Valve.
2.
Close the Domestic Control Valve
and all water outlets in the domestic
piping system.
3.
In addition to the Drain and Flow
Test Connection in the re sprinkler
system, close all drain valves and
replace all operated sprinklers as
necessary.
4.
Partially open the Main Control Valve
until the sound of owing water just
begins, then leave the Main Control
Valve in the partially open position.
5. After the re sprinkler system pres-
sure gauge indicates approximately
the same pressure as the supply
pressure gauge, fully open the Main
Control Valve.
6.
Open the highest elevation outlet on
the domestic system.
7.
Partially open the Domestic Control
Valve until the sound of owing water
begins. Allow the domestic piping to
ll slowly with water.
8.
Close the highest elevation water
outlet on the domestic system when
unaerated water begins to ow.
9.
Completely open the Domestic Control
Valve, then check that the domestic
system is properly pressurized by
verifying that at least three water
outlets in the domestic system can
ow full at the same time.
•
If the water outlets ow fully, the
Model RSV-1 Valve is set and ready
for service. Close the water outlets
on the domestic system.
•
If the water outlets do not ow
fully, re-close the Domestic Con-
trol Valve, wait a minimum of ten
seconds, and ensure that there is
no ow from the re sprinkler sys-
tem piping. Reopen the Domestic
Control Valve, then recheck that
the water outlets are owing fully.
Care and
Maintenance
The following inspection procedure for
the TYCO RAPID RESPONSE Model
RSV-1 Residential Shut-Off Valve
must be performed as indicated, in
addition to any specic requirements
of the NFPA. Any impairment must be
immediately corrected.
NOTICE
Make no attempt to repair any Model
RSV-1 Valve component in the field. The
Model RSV-1 Valve is not field-repairable.
If malfunction occurs, the entire unit
must be replaced.
The operational test and flow test
procedures result in operation of
the associated alarms, as well as an
interruption of the domestic water
supply service. You must notify the
owner, building occupants, and the fire
department, central station, or other
signal station to which the alarms are
connected.
Before closing a fire protection system
control valve for inspection or maintenance
work on the fire protection system that
it controls, obtain permission to shut
down the affected fire protection system
from the proper authorities and notify
all personnel who may be affected by
this action.
After placing a fire protection system in
service, notify the proper authorities and
advise those responsible for monitoring
proprietary and/or central station alarms.
The owner is responsible for the in-
spection, testing, and maintenance of
their re protection system and devic-
es in compliance with this document,
as well as with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addition
to the standards of any authority hav-
ing jurisdiction. Contact the installing
contractor or product manufacturer
regarding any questions.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualied Inspec-
tion Service in accordance with local
requirements and/or national codes
and standards.

TFP980

Operation Test Procedure
1. Fully open two or three water outlets
in the domestic piping system.
2.
To simulate a sprinkler operation,
open the Alarm Test Connection of
the re sprinkler system.
3.
Verify that any alarms are operating
and that the ow from the domestic
water outlets decreases to no more
than a trickle.
4.
Reset the Model RSV-1 Valve in ac-
cordance with the Valve Setting Pro-
cedure described in this data sheet.
Flow Test Procedure
1. While there is no water owing in the
domestic system, completely open
the Drain and Flow Test Connection.
2. While water is owing, record the
pressure reading on the re sprin-
kler system pressure gauge and
then compare this reading to previ-
ous readings.
If there is a signicant decrease
in pressure since the last time the
pressure reading was taken and this
decrease is not due to a normally
expected drop in the water supply
pressure, an impairment may exist
that should be immediately identied
and corrected.
3.
Close the Drain and Flow Test Con-
nection to allow the Model RSV-1
Valve to reset automatically. Automatic
resetting occurs within ten seconds.
4. After waiting ten seconds, completely
open at least three water outlets in
the domestic system and allow these
outlets to ow simultaneously.
If the water outlets ow fully, the
Model RSV-1 Valve is set and ready
for service. Close the water outlets
on the domestic system.
If the water outlets do not ow fully,
close the Domestic Control Valve
and verify that there is no ow from
the re sprinkler system piping, such
as at the Inspector’s Test Connec-
tion. Wait a minimum of ten seconds.
Re-open the Domestic Control Valve
and then recheck that the domestic
system water outlets are owing full.
