General
Description
The TYCO Model RSV-1 Residen-
tial Shut-Off Valves are intended for
use in dual-purpose residential water
supply piping that serves both domes-
tic and residential fire protection sprin-
kler 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 avail-
able water supply to the fire sprin-
kler 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 Res-
idential 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. There-
fore, in areas with limited water sup-
plies, it may eliminate the need to add
costly pumps, pressurized reservoirs,
or electrically operated domestic shut-
off valves. The Model RSV-1 Valve has
a built-in check valve in the fire sprin-
kler 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.
NOTICE
The Model RSV-1 Residential Shut-
Off Valves described herein must be

tion to the standards of any authorities

impair the integrity of this device.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
