About This Item

EXPANDED DETECTION: Detect water with sensors on the unit or expand coverage with the included 5 ft. water sensing cable. The additional length makes this alarm ideal for surrounding appliances or use in larger areas such as utility rooms.

EXTENDED AREA: The entire cable senses water allowing you to surround water heaters and sump pits, run under sinks, behind refrigerators and under dishwashers. Expand coverage by purchasing additional cables to cover an even larger area - up to 250 ft.
SIMPLE USE: Easy to use - once batteries are installed, insert the sensing cable into the cable sensor jack on the bottom of the detector, place detector so the cable is positioned where leaks are most likely to occur.

LOW BATTERY REMINDER: The water leak alarm provides a chirp alert to remind you it's time to change the 2 AA batteries (not included).
