3-3.7.6 Pressure Operated Trip, P/N 81-874290-000
Pressure Operated Trips are used to close off the hazard space upon system discharge. The
trips, operated by system pressure, are designed to release self-closing units for doors,
windows and dampers. The maximum load to be attached to a pressure trip is 100 lb (45.36
kg). This is based on a minimum pressure of 75 PSIG (5.17 bar gauge) at the pressure trip.

The Discharge Indicator may be installed in the discharge piping to visually indicate a system
