RDEPS120 Series switches are designed for use in dry pipe systems or pressure tanks and water pressure supplies of automatic water control valves.

The RDEPS120-1 has a single SPDT switch while the RDEPS120-2 model contains two SPDT switches. The RDEPS40 Series features field adjustable pressure sensitivity to provide an alarm response between 10 and 200 psi. The RDEPS120-1 is factory set to respond at 105 psi at decreasing pressure while the RDEPS120-2 is factory set to respond at 125 psi on rising pressure and 105 psi at decreasing pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the RDEPS120-2. The RDEPS120-1 and RDEPS120-2 supervisory pressure switches are NEMA 4 rated.
