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.

Technical Data Approvals UL and C-UL Listed Certified to all requirements of NSF/ANSI 61, Annex G and NSF/ANSI 372 Note: The 1 Inch (DN25) Model RSV-1 Residential Shut-Off Valve is suitable for use in water supply arrangements for residential fire sprinkler systems designed per NFPA 13D. Note: The 2 Inch (DN50) Model RSV-1 Residential Shut-Off Valve is suitable for use in water supply arrangements for residential fire sprinkler systems designed per NFPA 13, 13D, or 13R.

2 Inch (DN50) Valve In order for the 2 Inch (DN50) Model RSV-1 Valve to operate automatically at sprinkler activation, the fire sprinkler system from the water supply main to the most hydraulically remote sprinkler must be designed to provide a minimum single sprinkler flow of 8 GPM (30,5 LPM) when the water supply pressure at the water supply main is at its minimum expected value. The minimum single sprinkler flow rate of 8 GPM (30,5 LPM), required for use with the 2 Inch (DN50) Model RSV-1 Valve, does not take precedence over any more hydraulically demanding single sprinkler flow rate specified for the residential sprinklers in use.
