Our latest riser mount addition to the Whisper Quiet Series comes in three different configurations: S163, S253, & S418. The three models are only differentiated by the pressure switch presets, which are suited for specific dry pipe valves. The S163 model comes with a pressure switch set at 30-40 psi, which makes it compatible with all Standard Pressure Differential Dry Pipe Valves. Our S253 model is the perfect fit for Reliable’s DDX Low-Pressure Dry Pipe Valve due to its 23-28 psi preset pressure switch. The S418 model is specifically designed for Victaulic’s FireLock NXT Dry Pipe Valve with a pressure switch set at 13-18 psi. With their ultra-compact design and patented quick riser mount system, installation will be easier than ever. All three models are listed and NFPA 13 compliant for applications in the U.S. and Canada.
