Water Sensing Alarms

The Honeywell water detecting alarm detects water through the entire length of the cable, not just at sensitive spots - so if there's a leak, you'll know. The alarm includes a 4 foot cable; with the extension cable (sold separately), it can be expanded to 240 feet - making this the only system that can cover the entire perimeter of a room or basement, protecting you from leaks from the outside. The alarm is a loud 80 decibels, so you'll be sure to hear it!
