    EPSA40 Supervisory Pressure Switch

    EPSA40 supervisory pressure switches are designed for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler.

    Overview

    EPSA40 supervisory pressure switches are designed for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler. They feature field adjustable pressure sensitivity that provides an alarm response between 10 and 100 psi. All models are factory-set for use in a nominal 40 psi system. Their pressure adjustment wheel requires no special tools and does not affect switch synchronization. The EPSA40 supervisory pressure switches are NEMA 4 rated.
