Installation
Figure 1 illustrates a typical installation
arrangement using the TYCO Model
RSV-1 Residential Shut-Off Valve. The
arrangement may need to be modified
to meet the requirements of the author-
ity having jurisdiction. However, the
Model RSV-1 Valve must be installed
in accordance with this section.
General Instructions
A fire sprinkler water supply connec-
tion to a public water supply is usually
subject to local regulations concern-
ing 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.
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 flow.
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 orifice equal to or less
than the smallest K-factor sprinkler in
the system downstream of the Water-
flow 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.
