QolsysQS5536-840 IQ Wireless S-Line Flood Sensor

Product has scuff marks and looks used. The pull tabs to activate the devices were missing as well.

I wasted time and even returned one of these because it kept giving me false positives. However, when the second one was doing the same thing, I changed my settings that mange the sensor in a way that counters common sense (can't remember the setting). It would have saved a ton of time if the box told me to set up the sensor in that fashion, to begin with.

I purchased this addition to my Qolsys alarm system after a basement flood due to an AC condenser coil freeze up. I installed this just in time, as the coil froze up an hour after its installation! I was alerted immediately to address the issue with minimal flooding! Great product and NO falses either!

Works perfectly with my alarm system

Great product, easy to install

Easy to set up with Zwave alarm system

Added sensor in less than a minute on a qolsys iq2+ panel. Just go to advanced settings, enter installer code, add sensor, security sensor, auto learn sensor. After pulling the battery tabs, just open the cover to trigger a 'tamper' and the sensor will add to the panel. Name it and place it where you please. I tested mine right away, sent a alarm to the panel within a second or two and ADT was calling me within 5 seconds, woops! But all things considered, I am very happy with these sensors. Placed one in my basement next to my water heater and one in a guest bathroom behind the sink. You can literally add one below every faucet in your house and it'd probably be a good idea.. Alarm.com also makes a water shut off valve so when flood sensors are triggered, it will turn off the main water valve, how cool is that!?
