Common Concerns Answered
Some users find the 3-second delay slightly too long for immediate notification in critical situations, though it's designed to prevent nuisance alarms. Is this a concern?
The 3-second delay is a deliberate design feature to prevent spurious alarms caused by minor bilge fluctuations, thereby enhancing user confidence in the alarm's accuracy. For critical situations, this delay is minimal and still allows ample time for response before significant flooding occurs.
The price point is higher than basic float switch alarms. Is it worth the investment?
While the initial investment is higher than basic float switches, the Mires field effect technology ensures superior longevity and reliability by preventing corrosion and false alarms, leading to reduced maintenance and a greater sense of security over the lifespan of your vessel.
Can this alarm be affected by oil or debris in the bilge?
No, the Johnson Pump Bilge Alert utilizes patented Mires field effect technology with sealed fluid detectors that are completely isolated from bilge water, oil, and debris, preventing operational interference and false alarms.
Frequently Asked Questions
How does the Johnson Pump Bilge Alert High Water Alarm work?
It utilizes a patented Mires field effect with sealed fluid detectors that are isolated from bilge contaminants. When water reaches a specific level, it alters the Mires field, triggering the alarm without direct contact between the detector and the bilge contents.
What is the delay time before the alarm sounds?
The alarm features a 3-second delay before the audible signal is activated. This duration is engineered to prevent nuisance alarms from minor water surges.
Can this alarm be affected by oil or debris in the bilge?
No, the detector technology is completely isolated from the bilge water, oil, and debris, ensuring it will not be affected by such contaminants.
What is the voltage requirement for this alarm?
This high water alarm system operates on a 12V DC power supply.
How do I test the alarm functionality?
The alarm is equipped with a three-way rocker switch. Setting this switch to the 'Test' position will activate the alarm signal, allowing you to verify its operational readiness.
