Instead of relying on moving parts or a float switch, it uses field effect sensor technology to detect the presence of liquid directly, which keeps the design simple and reduces the chance of mechanical failure over time. Once the sensor is exposed to water for 8 seconds, the alarm activates a loud 100 db alert so it can be heard over engine noise, wind, and other onboard activity.\u003c\/p\u003e\u003cp\u003eThe alarm runs on a 12V DC power supply with a voltage rating of 10.5 to 14.4 V DC, matching standard marine electrical systems, and includes a switch panel with an integrated beeper so the audible warning is paired with a visible alert at the helm or panel location. The housing is made of black plastic for corrosion resistance in the marine environment typical of bilge installations. Because it has no moving parts, the Bilge Alert is a straightforward, low-maintenance way to add an extra layer of protection against unnoticed water intrusion, helping prevent bilge pump failures or slow leaks from going undetected until they become a serious problem.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson

Johnson Pump Bilge Alert (part 72303) is a 12V DC high water detection alarm that senses liquid in the bilge and sounds a 100 db alarm to warn the boat owner of rising water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long does it take for the alarm to activate once water is detected?\u003c\/strong\u003e Part 72303 activates its 100 db alarm after the sensor has been exposed to water for 8 seconds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the sensor detect water?\u003c\/strong\u003e It uses field effect technology to detect the presence of
