12V bilge pump control and alarm panel

The SEAFLO SFASP1-01 combines a three-position AUTO–OFF–MAN rocker switch, warning LED and ≥85 dB piezo buzzer in one marine panel. Wired with a compatible float or electronic-field bilge switch, it provides manual pump control, automatic pump mode and high-water warning functions in a 12V circuit.

Water detection requires an external switch; the panel itself is not a sensor.

Suitable boats and systems

  • 12V RIBs, fishing boats, sailing boats, day boats and small cruisers with a DC bilge pump drawing no more than 20 A.
  • New installations needing a clear AUTO–OFF–MAN control at the helm or electrical panel.
  • Replacement panels where the cut-out, current rating, wiring arrangement and external sensor are compatible.
  • Can be used with a float switch or SEAFLO electronic-field bilge switch.
  • The OFF/alarm behaviour must be understood before use; never leave a safety pump unintentionally disabled.

Check before ordering and installing

  • Confirm the system is 12V DC and the bilge pump's maximum/stall current does not exceed the panel rating.
  • Check the dashboard cut-out, rear clearance and moisture exposure before drilling.
  • Use a compatible water-level switch; the panel cannot detect bilge water without it.
  • Size fuse and cable for the pump load and cable length, not only for the short panel leads.
  • Label and test AUTO, OFF and MAN functions, the warning LED and buzzer after wiring and at regular intervals.
  • Package: one SEAFLO alarm switch panel. Pump, sensor, fuse, cable and mounting cut-out hardware are separate unless specifically pictured.

Frequently asked questions

Does the panel include a float switch?

The panel requires an external sensor. Check the product photographs for the exact supplied components.

Can it control any 12V bilge pump?

Only when the pump current, wiring and protection are within the panel's 20 A maximum rating.

What do AUTO, OFF and MAN do?

AUTO lets the external sensor control the pump, OFF disables normal pump operation, and MAN runs the pump manually while selected.

Can I use it on 24V?

No. SFASP1-01 is the 12V/20 A version; the 24V system requires the corresponding 24V panel.
