Multi-channel manifold RM-2 Riser

The TYCO Model RM-2 Riser Manifold features the necessary waterflow alarm, pressure gauge, alarm test orifice, drain, sight glass and check valve equipment in a single assembly for use in National Fire Protection Association (NFPA) standard NFPA 13* compliant commercial sprinkler systems. The riser manifold is available in a 2 in. to 6 in. range of sizes, and provides a cost effective and easy transition arrangement to control valves and system piping. The riser manifold may be installed in either a horizontal or vertical orientation, for both single sprinkler rises and floor control in high-rises. A TYCO Model TD-2 Test and Drain Valve installed on the riser manifold as shown in Figure 2 provides a simplified means for testing of waterflow alarm devices and draining for feed mains. The pressure relief valve, integrated in the TYCO Model TD-2 Test and Drain Valve, has an adjustable range of 100 psi (6,9 bar) to 310 psi (21,4 bar). Excess system pressure is exhausted internally through the TD-2 valve’s drain outlet. For more information about the Model TD-2 Test and Drain Valve, refer to Technical Data Sheet TFP965.
