Essential Info

Protect your home from water damage before it happens with Water Defense Water Alarm from Honeywell. The Water Alarm comes with a 4 foot long water sensing cable which is able to detect water along the entire length of the cable. If the cable detects water it will instantly emit an audible alarm to alert those around that there is a leak in the appliance(s) it is setup to monitor. An added feature with the Water Defense Water Alarm is that it is an expandable system. While it comes with a 4 foot long cable it is not limited to this if you want to use it to monitor a larger area. Water sensing cable extensions for this system can be added making it expandable up to 250 feet, expandable cable sold separately. The Water Alarm will also provide peace of mind when setup in areas that are not frequently observed such as water heaters and basement perimeters which could potentially go unnoticed for a time if a small leak were to start. The Water Defense Water Alarm base unit is powered by a 9V battery, sold separately, and the unit will emit an audible chirp to alert when the battery needs to be replaced.
