The Winland WBTX319 is a wireless WaterBug RF flood sensing probe married to a 319.5 MHz wireless transmitter. The sensing probe can be mounted horizontally or vertically in relation to the area to be monitored. It is connected to the transmitter by a cable that is 6' (1.8m) in length.

Water leaks cause millions of dollars in damage to homes and businesses each year. More and more, insurance companies are requiring environmental protection, such as with flood and low-temp sensors when an alarm system is in use, and in exchange for this type of coverage, there is usually a discount associated with the homeowner's or commercial insurance.

The flood sensing probe of the WBTX319 works by signaling an alarm when the two metal prongs of the probe are shorted together by water. This means that if water touches one probe, but not the other, there will be no alarm. However, if water rises enough to bridge the gap between both metal prongs, and this bridge, also called a short, lasts for more than three (3) seconds, then an alarm condition will be indicated. The probe is constantly sensing for water, and it must get two positive indications within the three (3) second window before an alarm will be activated.

The WBTX319 is not a stand-alone unit. In order to notify anyone of a flood condition, it must be used in conjunction with an alarm panel such as a Qolsys IQ Panel 4, Interlogix SimonXT, SimonXTi, SimonXTi5, or Qolsys IQ Panel 2 Plus w/AT&T LTE or Qolsys IQ Panel 2 Plus w/Verizon LTE. When using this product with a Qolsys panel, be sure that it is a version that supports 319.5 MHz sensors, as not all Qolsys variations do. You can tell your panel supports 319.5 MHz sensors if it comes in a box with a Gold band on one end of the box.

The sensing probe should be mounted where a flood condition is most likely, such as in laundry areas, bathrooms, basements, near a sump pump, water heater, under sinks or dishwashers. The probe can either be mounted to the floor horizontally, or on the wall, with the probes pointed down toward the area where water will gather. Be careful mounting where the probes may come in contact with concrete, as it can be somewhat conductive, and may cause false alarms.

The transmitter portion of the sensor can be mounted up to six (6) feet (1.8m) from the probe. It should be mounted where it can get a signal to the receiver for the alarm panel. Avoid mounting it on metal, or where a large metal object, such as a refrigerator, large metal duct work, large mirror, etc. may block the signal from the transmitter from reaching the receiver.

To test the sensor, and to learn it into the alarm panel, use a wet cloth, or even your finger to make contact between the two metal prongs on the probe. Within about three (3) seconds, the transmitter should send a signal to the alarm panel. You can use this to learn the serial number into the zone you will use to monitor this device. Once programming is done, test in the same way to be sure the unit is working properly. Consult the installation instructions for your alarm panel to determine what the best response type for the zone is. Generally speaking, it should be a 24-hour response, and can indicate either an alarm, or a trouble condition or in some cases a trouble condition if the system is disarmed at the time the alarm occurs, and an alarm if it occurs when the system is armed.
