Installation
Figure 1 illustrates a typical installation
arrangement using the TYCO RAPID
RESPONSE Model RSV-1 Residen-
tial Shut-Off Valve. The arrangement
may need to be modifi ed to meet the
requirements of the authority having
jurisdiction. However, the Model RSV-1
Valve must be installed in accordance
with this section.
General Instructions
A fi re sprinkler water supply connec-
tion to a public water supply is usually
subject to local regulations concern-
ing metering and backfl ow prevention
requirements. Consult with the local
water authorities concerning local
requirements that may apply to the
arrangement of these components in
the fi re sprinkler system water supply.
For the 1 Inch (DN25) Valve, the
maximum water supply service line is
1 Inch (DN25).
Step 1.
Ensure that the water supply
to the Model RSV-1 Valve is free of
contaminants and particles of a size
greater than 1/8 inch (3,2 mm).
Step 2.
Install the Model RSV-1 Valve
vertically with the Supply Port at the
bottom, 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 fl ow.
A suitable clamp along the water
supply riser piping is recommended to
provide support for the weight of the
Model RSV-1 Valve.
Step 3.
Place a Domestic Control Valve
between 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.
Step 4.
The Drain and Flow Test Con-
nection (Ref. 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.
Step 5.
Install an Alarm Test Connec-
tion with a test orifi ce equal to or less
than the smallest K-factor sprinkler in
the system downstream of the Water-
fl ow Detector.
Step 6.
Apply pipe-thread sealant spar-
ingly 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 initially
fi lling the fi re sprinkler and domestic
system piping with water or after a fi re
sprinkler operation (Ref. Figure 1).
Step 1.
Close the Main Control Valve.
Step 2.
Close the Domestic Control
Valve and all water outlets in the
domestic piping system.
Step 3.
In addition to the Drain and
Flow Test Connection in the fi re sprin-
kler system, close all drain valves and
replace all operated sprinklers as
necessary.
Step 4.
Partially open the Main Control
Valve until the sound of fl owing water
just begins, then leave the Main Control
Valve in the partially open position.
