ELK-319WA Water Alarm Sensor – A wireless flood sensor designed to detect the presence of water leaks or flooding. The ELK-319WA comes in two parts: a small transmitter box and a remote water probe on a 6-foot cable. The transmitter mounts on a wall or above the floor, while the low-profile probe is placed at the lowest point where water would collect (sump pit, under a water heater, beneath a sink, etc.). When water forms a bridge between the contacts on the probe, the sensor signals an alarm condition immediately. To prevent false alarms from condensation or humidity, the probe’s contacts are elevated slightly off the floor. The ELK-319WA continuously monitors for water and even double-checks before triggering (it requires two positive confirmations of water presence). It also checks its battery status hourly and sends supervision signals so the panel knows it’s active. This sensor allows early detection of leaks – potentially saving thousands in water damage by alerting you or triggering a water shutoff when a leak is detected. It’s fully wireless and battery powered, making it easy to install in basements, laundry rooms, or bathrooms.

Key Features:

  • Early Leak Detection: Senses water leaks or flooding at the very start – place the probe by sump pumps, washing machines, water tanks, pipes, or basement floors to catch leaks before catastrophic damage occurs
  • Remote Sensing Probe: 6′ cable lead lets you put the detector’s probe in hard-to-reach spots or low-lying areas, while the transmitter can be mounted up higher on a wall (keeping electronics dry) 
  • False Alarm Prevention: Probe contacts are raised slightly above floor level to avoid alarms from mere condensation or damp concrete. The sensor also requires two consecutive water confirmations, ensuring it truly senses liquid water before triggering
  • Hourly Self-Check: Performs hourly battery and supervision checks, alerting the panel of any issues – so you know the sensor is always ready
  • Easy Install & Integration: Mount transmitter with screws or adhesive (above flood line), drop the probe end at floor or in drain pan. Enrolls like any door/window sensor (319.5 MHz) – when water is detected, it transmits an alarm to the panel to initiate alerts or automation (like a smart water shutoff valve)

Technical Specifications:

  • Detection Method: Gold-plated water sensor probe (two contacts). When water bridges the contacts, electrical conductivity triggers the alarm. Probe can be reused indefinitely – simply dry it after an alarm event
  • Cable Length: 6 feet (approx. 1.8 m) flexible cable between probe and transmitter. Allows placement in sump pits or under appliances while mounting the radio unit at a convenient location
  • Battery: Two (2) CR2032 coin-cell batteries in transmitter. Designed for multi-year operation; panel receives a low battery signal when replacement needed
  • Wireless Specs: 319.5 MHz one-way signal, compatible with ELK’s 319 series receivers and any Interlogix/ITI 319.5 system. Supervised and tamper-protected (tamper triggers if transmitter cover removed)
  • Operating Conditions: 32°–122°F (0°–50°C), up to 95% RH. Meant for indoor use (or areas like covered valve boxes – transmitter is not waterproof). Note: Do not submerge the transmitter – only the probe is water-resistant
