The water defense water-sensing alarm detects leaks near major appliances around the home or office.
The water-sensing cable detects dampness along its entire 4-foot length and can be easily tucked away near appliances or hidden under baseboards around carpet. A separate RWD41-compatible 8-foot extension cable (the RWD80) is available for an even more comprehensive range. The base unit (powered by a 9-volt battery, not included) can be mounted on a wall or another flat surface and comes with a 6-foot leader cable. Installation is a cinch thanks to plug-and-play features built into the system: Just add batteries, plug in the leader cable and the water-sensing cable, and mount the base unit with two-sided tape (which the securing clips also employ to hold the water-sensing cable in place). An 80-decible alert sounds when water is detected, permitting for early discovery and intervention of leaks, and can be turned off by wiping the sensor cable with a dry cloth.
Leak Detection and Protection
Water damage is the second-leading cause of home insurance claims nationwide, and 80 percent of all home water claims are caused by plumbing and major appliances. A surprisingly large amount of water can escape from the smallest of cracks--a 1/8-inch crack in a pipe can release up to 250 gallons of water a day. Insurance companies recommend the installation of water-detection systems like the RWD41 as the best protection against the potentially expensive and stressful damage caused by leaks.
Honeywell is a Fortune 100 company that can trace its roots back to 1885, when inventor Albert Butz patented the furnace regulator and alarm. Today, Honeywell continues to innovate and manufacture technologies that address challenges linked to global macrotrends such as safety, security, and energy.
What's in the Box

The cable is very sensitive, and the alarm sounds within a couple of seconds of the cable getting wet. When you dry the cable, it takes less than a second for the alarm to go silent. The alarm is LOUD - loud enough to wake you up.
Like a smoke detector, this alarm just sits there silently, doing its thing, and you never know it's working until ... well, until it works. You should probably test it once a year by wrapping a wet cloth around the cable or dunking it in a cup of water.
And, if you open the plastic enclosure, it appears that their circuit design was meant to serve 2 purposes, one for the "low-end" model (the RWD41) and one for a "higher-end" model. You can see some components are not populated, 2 of which are a switch and a relay. By probing some of those points with a meter, it appears that, when water is detected the output (which is meant to drive a relay) goes high until the switch is closed. So, if you populated the parts, it would work great with an alarm panel. You would just connect the relay contacts to a N.C. loop (assuming the relay is an N.C. relay). When water is detected the alarm would beep and the contacts would open until someone comes and pushes the button to "clear" it.
Perhaps I can get some information out of honeywell on what the part numbers for these missing parts are, or just wire up a simple external circuit of my own with a relay. If anyone has done any hacking with this, please e-mail me! sfenwick at gmail dot com.
It went off the other day, we only heard it because someone went downstairs to get something out of the room where it lives. This is really, really, too quiet for practical use.
Installation was very easy and I was going to purchase a few of these units for my house so I purchased this one to see how I liked it. I really would have expected a better alarm from Honeywell. Honeywell should build a replacement box for this unit with an alarm that is as least as loud as a smoke alarm.
Off & on we've encountered water problems in our basement....at least 3 times when our water heater broke & a few other when there was exceptional flooding in our area. This cable would've alerted us to the problems...however, it's not loud enough to be heard upstairs. Our basement steps are located in the garage...so there's no basement door that can be left open to hear any 'basement sounds.' I've been known to put my ear to a register when I hear noises downstairs. Thankfully, we haven't had any water issues since I received this water sensor. So I put water on the cable myself, & dried the cable to stop the alarm. However to stop the alarm in a real-life situation, it might work better to disconnect the sensor/water detector cable from the unit, and if that doesn't work, you'll have to remove the battery.
Purchasing extension cable will make this unit more useful. Honeywell RWD80/T Water Defense Water Sensing Alarm Extension Cable
This sensor is easy to set-up and install. Double stick tape is included to mount the alarm unit on a dry wall & there's 6' of leader connection cable (we can mount the alarm close to the basement ceiling & possibly better hear the alarm in our living area.Read more ›

I put a brand new battery in it and nothing. Even having the sensor cord under running water doesn't make it sound the alarm. Don't waste your money on this.Published 15 days ago by David Naumowicz
