Tyco Wet Pipe Sprinkler Systems Retard Chamber

Model RC-1 Retard Chamber For Variable Pressure Wet Pipe Sprinkler Systems 300 psi (20,7 bar) 

General    Description
The Tyco® Model RC-1 Retard Chamber is required in installations that will be subject to pressure variations, as are generally associated with public water supplies, in order to help prevent false alarms. The RC-1 is specifically intended for use as a separately ordered item for the Model AV-1-300 Alarm Check Valve (TFP910). It can, however, also be used as a separately ordered item for changing out older style Retard Chambers used with the Central Model F/G, Gem Model A, or Star Model E/F Alarm Check Valves. 

The Model RC-1 Retarding Chamber is a re-designation for the Gem Model F211 for use with Gem Model F20/ F200/F2001 Alarm Check Valves, as well as the Star Model S310 for use with Star Model S30/S300/S3001 Alarm Check Valves.


Technical  Data
Approvals

UL and ULC Listed, as well as FM, LPCB, and VdS Approved for use with the following Alarm Check Valves:

    Model AV-1-175 Gem 
    Model F20/F200/F2001 Gem 
    Model A Star 
    Model S30/S300/S3001

Working Water Pressure 
300 psi (20,7 bar)

Construction 
The Model RC-1 Retard Chamber shown in Figure 1 is cast iron, and a 3/4" x 1/2" x 3/4" Tee is provided at the outlet (top) for connection of a pressure alarm switch and/or water motor alarm. The Restriction Assembly shown in Figure 2 is provided with the AV-1-300 trim or ordered separately for retrofitting other valves. This assembly is comprised of brass restrictions assembled to a cast iron or malleable iron threaded tee fitting. The screen is stainless steel. 


Operation 

When water flows steadily into the sprinkler system due to sprinkler operation, the Waterway Clapper in the Alarm Check Valve opens as shown in Figure 3. Water is then permitted to flow into the centrally located groove in the Seat Ring and out through the Alarm Port towards the Restriction Assembly. 

When the flow through the Inlet Restriction of the Restriction Assembly exceeds the flow out through the Outlet Restriction, the Retard Chamber begins to fill. Subsequently, the Water Motor Alarm and/or the Pressure Alarm Switch activate. The alarms continue to operate as long as the Waterway Clapper remains open. When the Clapper closes as a result of discontinued water flow, water in the alarm lines automatically drains out through the 1/8 inch (3,2 mm) drain orifice in the Restriction Assembly. In the case of variable pressure systems, a transient surge in supply pressure that is sufficient only to open the Clapper momentarily will not cause a false alarm. The volume of the Retard Chamber is sufficiently large enough that it will not fill to operate the connected alarm devices. Any water in the alarm line is then automatically drained, further reducing the possibility of a false alarm due to a successive transient surge in supply pressure.
