Supervisory pressure switch DPS40

The DPS40 series pressure type supervisory pressure switches shall be installed on system piping as designated on the drawing and/or as specified herein. Switched shall be provided with 1/2” NPT male pressure connection and to detect an increase and/or decrease from normal system pressure in automatic fire sprinkle system. Typical applications are: Dry pipe valves, Pre-action valves, or pressure tanks. The DPS40 series pressure switches are factory set for use in a normal 40psi system. The DPS40-1 is factory set to respond at 30psi at decreasing pressure and DPS40-2 is factory set to respond at 50psi at increasing pressure and 30psi at decreasing pressure

? Maximum System Pressure:  300PSI (2.07MPa)

? Factory Setting:       DPS40-1 operates at decreasing pressure at 30psi

                                   DPS40-2 operates at increasing pressure at 50psi

                                         and at decreasing pressure at 30psi

? Differential:             Approximately 3psi@10psi, 6psi@100psi

? Maximum Adjustment  Pressure Range:             10 to 60psi

? Contact Ratings:                   DPS40-1: One set SPDT (Form C)

                      DPS40-2: Two sets of SPDT (Form C)
