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.
Contact the installing contractor
or product manufacturer with any
questions.
The TYCO Model RSV-1 Residential
Shut-Off Valves are intended for
use in dual-purpose residential water
supply piping that serves both domestic
and residential fire 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 13, 13D,
or 13R.
When a fire sprinkler operates, the
Model RSV-1 Residential Shut-Off
Valve automatically diverts the available
water supply to the fire sprinkler
system. Consequently, when the
Model RSV-1 Valve is utilized, the
system designer does not need to
add the domestic flow demand to the
fire sprinkler system flow demand, as
would otherwise be required by NFPA
13D or 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 fire sprinkler flow
demand, or it is necessary to increase
the effectiveness of the fire sprinkler
system by automatically diverting the
domestic flow.
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 electrically operated domestic shutoff
valves. The Model RSV-1 Valve has
a built-in check valve in the fire sprinkler
system outlet that eliminates the
need for a separate check valve. Also,
the Model RSV-1 Valve automatically
resets, thereby eliminating the need for
valve disassembly after a fire sprinkler
system test or operation.

Water Supply Requirements:
1 Inch (DN25) Valve:
In order for the 1 Inch (DN25) Model
RSV-1 Valve to operate automatically
upon sprinkler operation, the fire
sprinkler system from the water main
to the most hydraulically remote sprinkler
must be designed to provide a
minimum single sprinkler flow of 12.5
GPM (47,3 LPM) when the supply
pressure at the main is at its minimum
expected value.
The minimum single sprinkler flow
rate of 12.5 GPM (47,3 LPM), required
for use with the 1 Inch (DN25) Model
RSV-1 Valve, does not take precedence
over any more hydraulically demanding
single sprinkler flow rate specified for
the residential sprinklers in use.
When performing hydraulic design calculations
for the fire sprinkler system,
you need not account for the trickle
flow 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).
