Honeywell's RWD41 water defense water-sensing alarm offers superior protection against leaks and water damage near potential trouble spots close to plumbing around the home or office. Patented 4-foot cable solution extends the detection zone offered by traditional spot detetectors by 3100%. Water Sensing Cable detects water on entire length of cable. Place the cable in spots where you do not usually observe, water heaters, sump pumps, under sinks, around toliets, behind wahing machines and dishwashers. 6 feet of Leader Cable allows the alarm unit to be mounted on walls or another room and 4 feet of sensing cable is included which is expandable up to 250 feet - the only system that can run around the entire perimeter of a room or basement. This unit also gives off a chirp sound when the battery is low.
