What signal does the discharge pressure switch provide?

Explanation:
The main idea is that the discharge pressure switch serves as a verification that agent is actually flowing in the system. When the pressure in the discharge piping rises to its set point after actuation, the switch closes and sends an alarm-initiating signal to the releasing panel. That panel then starts the release sequence and annunciates the event as part of the system’s response. This signal is a control communication to the releasing panel, not a local alarm or a maintenance notice, which is why it’s described as an alarm-initiating signal to the releasing panel.
