Johnson Pump Ultima 12V Bilge High Water Alarm

The Johnson Pump Ultima 12V Bilge High Water Alarm gives an early warning when bilge water rises to an abnormal level. Its sealed electronic water detector senses the presence of water and sends a signal to the panel-mounted alarm, helping alert the operator that normal bilge pumping may not be keeping up.

Because the detector is sealed and does not rely on exposed electrical contacts in the water, it is built to resist corrosion and interference from common bilge contamination. The control includes a test, off, and armed selection so the alarm circuit can be checked and placed in the appropriate operating mode.

Install the detector above the normal bilge-pump activation level and confirm electrical supply, circuit protection, panel visibility, alarm audibility, and wiring routing. Test the warning system after installation and during routine maintenance. A high-water alarm supplements properly sized primary and backup pumps rather than replacing them.

• The detector triggers an alarm when water reaches the selected high-level point.
• Sealed electronic detection helps resist corrosion and contamination.
• The panel control gives a dedicated test function.
• The alarm helps draw attention when bilge conditions require operator action.
