The Sea & Sea Leak Alarm with Manual Pumpprevents water leakage into your underwater camera housing by creating negative pressure inside the housing and monitoring the change of pressure. The air pressure sensor checks the integrity of your housing's seal before you dive. The leak sensor reacts and issues alerts with an LED indicator if water leaks into the housing during the dive.

It monitors the air pressure inside the housing produced by the vacuum pump, and it displays the status three-color LED lighting/flashing and an alarm.

Measures air pressure and occurrence or nonoccurrence of water leakage in the housing every 0.2 seconds (200ms). It constantly monitors the inside of the housing.

Judges the air pressure value by converting the temperature to 68°F. It does not allow malfunction caused by pressure fluctuations due to heat generated by the camera or changes in water temperature.

Battery life is about 250 hours when the power is on. One battery charge enables long-term usage.

Q: 7. How do you turn off the alarm beeping after it has gone off? I pressed Alarm Reset, but I wasn't sure that was the best way. Thanks for any help,

A: Alarm reset button has the benefit of leaving the alarm on for the next day but silencing it now. The off button turns it off so it won't sound again until you turn it back to buzz or radio to set it. On Fridays, I turn the alarm off using the slider that says off buzz radio. Then turn it back on for Monday on Sunday night.
