General

Description

The Rapid Response

, Model RSV-1

Residential Domestic Shutoff Valves

are intended for use in dual-purpose

residential water supply piping that

serves both domestic and NFPA 13D

residential fire protection sprinkler

system needs.

When a fire sprinkler operates, the

RSV-1 Valve will automatically shut off

water flow to the domestic system and

divert the available water supply to the

fire sprinkler system. Consequently,

when the RSV-1 is utilized, the system

designer need not add the domestic

flow demand to the fire sprinkler sys-

tem flow demand.

Use of the Model RSV-1 Residential

Domestic Shutoff Valve shouldbe con-

sidered when either the water supply

cannot adequately provide for both the

domestic design demand and fire

sprinkler flow demand, or it is desir-

able to increase the effectiveness of

the fire sprinkler system by automat-

ically shutting off domestic flow.

The RSV-1 maximizes the effective

use of an existing water supply and,

therefore, in areas with limited water

supplies, it may eliminate the need to

add costly pumps, pressurized reser-

voirs, or electrically operated domestic

shutoff valves. The RSV-1 has a built-

in check valve in the fire sprinkler sys-

tem outlet that eliminates the need for

a separate check valve. Also, the

RSV-1 automatically resets, thereby

eliminating the need for valve disas-

sembly after a fire sprinkler system

test or operation.

The Model RSV-1 Residential Domes-

tic Shutoff Valve is a redesignation of

the Gem Model F540 and Star Model

S370 Residential Domestic Shutoff

Valves.

tic Shutoff Valves described herein

The Tyco Rapid Response Model RSV-1 Residential Domestic Shutoff Valve is a crucial component in dual-purpose residential water supply systems, designed to serve both domestic water needs and NFPA 13D residential fire protection sprinkler system requirements. Its primary function is to automatically divert water flow from the domestic system to the fire sprinkler system when a fire sprinkler operates, ensuring that the available water supply is prioritized for fire suppression. This eliminates the need for system designers to add domestic flow demand to the fire sprinkler system's flow calculations.

Function Description:

The RSV-1 Valve operates by automatically shutting off water flow to the domestic system and diverting the entire available water supply to the fire sprinkler system upon sprinkler activation. This is particularly beneficial in areas with limited water supplies, as it maximizes the effective use of the existing water supply and can negate the need for costly pumps, pressurized reservoirs, or electrically operated domestic shutoff valves. A key feature is its automatic resetting capability, which means the valve returns to its normal standby position after a fire sprinkler system test or operation without requiring manual disassembly. The valve also incorporates a built-in check valve in the fire sprinkler system outlet, eliminating the need for a separate check valve.

In its normal standby position, the Piston, assisted by a Spring, is in the down position. This allows the Fire Sprinkler Seat to function as a conventional check valve and ensures water is available on demand through the Domestic Flow Passage and out the Domestic Port for domestic use. When a fire sprinkler operates and a minimum design water flow (12.5 GPM) is achieved, the Piston moves upward. In this "up" position, water flow to the Domestic Flow Port is diverted to the Fire Flow Port, prioritizing the fire sprinkler system.

The valve's design minimizes the Piston's upward movement unless sustained fire sprinkler system flow occurs. However, due to air pockets in most fire sprinkler systems, the Piston may momentarily move upward during a supply pressure surge. This momentary opening and reclosing traps a portion of the pressure increase within the fire sprinkler system, which helps reduce the possibility of a subsequent surge causing a waterflow detector to signal a false alarm (unless a by-pass is installed as per Figure 2).

- ISO: ISO Rc1 (DN25) Model RSV-1, P/N 52-540-1-011.
Minimum Water Supply Requirements: To automatically operate, the fire sprinkler system 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. This minimum flow rate does not supersede higher hydraulically demanding single sprinkler flow rates specified for the residential sprinklers being used.
By-Pass Restriction: A small amount of water trickles through the By-Pass Restriction to the Domestic Port when the Piston is in the full up position. This trickle flow (less than 1/4 GPM or 0.9 LPM for a typical residual pressure of 40 psi or 2.8 bar) allows for automatic resetting of the RSV-1 Valve without draining the fire sprinkler system after an operation or test. It also equalizes Supply and Domestic Port pressures when the Manual Domestic Shutoff Valve is closed, allowing the Piston Assembly to return to standby.

Usage Features:

Vertical Installation: The RSV-1 must be installed vertically with the Water Supply Port at the bottom, the Fire Sprinkler Port at the top, and the Domestic Port at the side.
Backflow Prevention: If local regulations require a backflow prevention device in the fire sprinkler line downstream of the RSV-1, a by-pass (as shown in Figure 2) must be installed. However, installing the by-pass defeats the RSV-1's ability to perform as a check valve.
Contaminant-Free Water Supply: The water supply to the RSV-1 Valve must be free of contaminants and particles larger than 1/8 inch (3.2 mm).
Flow Direction: The valve must be installed so that the arrows cast on the Body point in the direction of flow.
Domestic Control Valve Placement: A Domestic Control Valve should be located between the RSV-1 Valve and the domestic system, with its inlet within 12 inches of the Domestic Port of the RSV-1 Valve.
Drain and Flow Test Connection: A minimum 1/2 inch (DN15) connection is recommended for systems per NFPA 13D.
Alarm Test Connection: An Alarm Test Connection with a test orifice equal to or less than the smallest K-factor sprinkler in the system should be located downstream of the Waterflow Detector.
Pipe Thread Sealant: Apply sparingly only to male pipe threads assembled to the three ports of the RSV-1 Valve, with Teflon-based sealant recommended.

Maintenance Features:

Inspection and Maintenance: The owner is responsible for maintaining the fire protection system and devices in proper operating condition, in compliance with the document, applicable NFPA standards (e.g., NFPA 25), and any other authority having jurisdiction.
Qualified Service: It is recommended that automatic sprinkler systems be inspected, tested, and maintained by a qualified Inspection Service.
No Field Repair: No attempt should be made to repair any RSV-1 valve component in the field.
Notification Procedures: Before closing a fire protection system control valve for maintenance, permission must be obtained from proper authorities, and all affected personnel must be notified. After placing the system back in service, authorities and those monitoring alarms must be advised.
Valve Setting Procedure: A detailed procedure is provided for initially filling the fire sprinkler and domestic system piping with water or after a fire sprinkler operation. This involves closing control valves, opening outlets, partially filling, and verifying proper pressurization and flow.
Operation Test Procedure: This involves fully opening domestic water outlets, opening the Alarm Test Connection to simulate a sprinkler operation, verifying alarm activation, and observing the decrease in domestic water flow. The valve is then reset using the Valve Setting Procedure.
Flow Test Procedure: This involves completely opening the Drain and Flow Test Connection (with no domestic flow), recording the fire sprinkler system pressure gauge reading, and comparing it to previous readings to identify any significant pressure decrease. The valve automatically resets within ten seconds after closing the Drain and Flow Test Connection. After resetting, domestic water outlets are opened to verify full flow.
