Description
EPSA10 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. They are factory-set to respond at 4 to 8 psi on rising or falling pressure. The switch’s pressure adjustment wheel requires no special tools and does not affect the switch. The EPSA10 Series switches are NEMA 4 rated.
