Description
Johnson Pump High Water Alarm 12V | Boat Supply Store
Mitigate rapid bilge flooding with a proactive early warning system designed for continuous operational integrity. This 12V alarm utilizes a patented Mires field effect with completely sealed fluid detectors, ensuring zero contact with bilge water, oil, or debris for unparalleled corrosion resistance. The system incorporates a deliberate 3-second delay to prevent nuisance alarms from minor bilge activity while still providing critical notification for serious water intrusion, a vital feature for vessels operating offshore or with diesel engines where bilge contamination is a known risk.
Key Features
- Detects high water levels with patented Mires field effect technology.
- Guarantees corrosion-free operation via totally sealed fluid detectors.
- Eliminates false alarms as detectors never contact bilge contaminants.
- Ensures reliable performance unaffected by oil or debris accumulation.
- Provides a 3-second delay to prevent nuisance alarms.
- Offers versatile control with a three-way rocker switch (Test, Off, Armed).
- Operates efficiently on standard 12V DC systems.
- Delivers peace of mind through advanced, reliable detection.

Common Concerns Answered
Is the 3-second delay too long for immediate notification?
The 3-second delay is intentionally incorporated to prevent nuisance alarms caused by normal bilge activity such as water movement during vessel operation or minor pump cycles, while still ensuring timely notification of significant flooding events.
Why is this alarm more expensive than basic float switch alarms?
The higher price reflects the advanced, patented Mires field effect technology, sealed, non-corrosive fluid detectors, and immunity to oil and debris, which significantly increases long-term reliability and reduces maintenance compared to traditional float switches.
How does the Johnson Pump Bilge Alert differ from a standard float switch?
Unlike standard float switches that are directly exposed to bilge water and contaminants, potentially leading to corrosion and false alarms, the Bilge Alert uses sealed Mires field effect sensors that are isolated from the bilge environment, providing superior reliability and longevity.
Frequently Asked Questions
How does the Johnson Pump Bilge Alert High Water Alarm work?
It employs a patented Mires field effect technology where sealed fluid detectors are positioned in the bilge; when water reaches a predetermined level, it activates the field effect, triggering the alarm without the detector physically contacting the water or contaminants.
What is the delay time before the alarm sounds?
The alarm incorporates a 3-second delay before activating the signal to prevent nuisance alarms from minor water fluctuations.
Can this alarm be affected by oil or debris in the bilge?
No, the totally sealed fluid detectors are completely isolated from bilge water, oil, and debris, ensuring unaffected and reliable operation even in contaminated bilge environments.
What is the voltage requirement for this alarm?
This high water alarm system is designed for 12V DC electrical systems commonly found on recreational and commercial vessels.
How do I test the alarm functionality?
The included three-way rocker switch has a 'Test' position which, when activated, simulates a high water condition and verifies the alarm and its associated indicator are functioning correctly.
