Discharge Pressure Switch, P/N 02-12534, is used to provide a positive pneumatic confirmation to the control system that the Fike Fire Suppression system has been discharged. When a system is discharged, the discharge pressure switch is required to provide the input to the control system needed to activate various audio/visual warning devices and auxiliary relays. The switch is operated pneumatically using the agent pressure in the discharge piping network. The unit has a single-pole, double-throw switch that can be wired for normally open or normally closed operation. The minimum pressure required to activate this switch is 2 bar.
