The DPS*0 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 DPS*0 series pressure switches are factory set for use in
a normal *0psi system. The DPS***1 is factory set to respond at
*0psi at decreasing pressure and DPS***2 is factory set to respond
at *0psi at increasing pressure and *0psi at decreasing pressure

Operating Pressure DPS***1 operates at decreasing pressure at *0psi
                                DPS***2 operates at increasing pressure at *0psi
                                and at decreasing pressure at *0psi
