Pressure Switch (200 psi) Saiginomiya (SYS-C120X24) is a single-function pressure switch that monitors fluid (water or air) pressure in piping systems. In fire-fighting applications, it can be used to detect pressure drops or rises in fire-pump discharge lines, sprinkler risers, deluge system pilot lines, or other critical fire-suppression pipelines. Upon reaching a preset pressure setpoint, it toggles an electrical contact which can trigger alarms, start or stop pumps, or initiate control sequences.
| Fire Pump Control | Monitor the main fire-pump discharge or jockey pump line - when pressure falls below a threshold (due to sprinkler activation or leakage), the switch closes to start pump | ||||||||||||||||
| Sprinkler riser monitoring (wet-pipe system) | When a sprinkler head opens and pressure drops, the switch signals the fire-alarm control panel or activates a supervisory signal. | ||||||||||||||||
| Deluge or pre-action system | Sense pilot-line pressure drop or water-fill pressure; activate deluge valve or open control circuit. | ||||||||||||||||
