Smart Shield Systems

Flood/freeze Sensor

Catch leaks early and get alerted before pipes freeze. Our Flood/Freeze Sensor uses a low-profile transmitter with a floor-level water probe plus built-in temperature monitoring. When the probe detects standing water or the room drops toward freezing, your system sends instant alerts and can trigger automations (like shutting off a smart water valve).

Why Choose This with Smart Shield Systems


  • Pro placement: we mount the probe at the right floor point (under sinks, near water heaters, by sump pumps) and test reporting/timing.

  • Actionable automations: pair with Alarm.com scenes—text/push alerts, siren rules, and optional valve shutoff.

  • Ongoing support: battery reminders, range checks, and seasonal testing.


Key Features


  • Water leak detection: probe reports a wet alarm after a short confirmation window, and sends a restore when dry—avoids nuisance trips. (Example: wet/dry confirmed after ~3 minutes.)

  • Freeze protection: built-in temperature sensing can alert on low-temp and high-temp conditions (e.g., ≤ 41°F freeze, ≥ 95°F heat, each confirmed ~5 minutes).

  • Wireless, supervised: periodic “check-in,” tamper reporting, and low-battery notifications to the panel/app.

  • Fresh/salt/tap water compatible detection.


Product Specifications (Representative Class)


Exact details vary by model/brand; we’ll confirm on your quote.

  • Wireless: Security-grade RF to your panel (e.g., 345 MHz or 319.5 MHz families).

  • Temperature alarms: Freeze ~41°F (5°C) and Heat ~95°F (35°C), each after ~5 min (panel logs “clear” after temps recover).

  • Water alarm logic: Wet after ~3 min of detection; Dry after ~3 min clear.

  • Power: Long-life lithium battery (e.g., CR2 on 345-MHz models), ~5-year typical life.

  • Operating range (env.): around 32–120°F; 5–95% RH, non-condensing.

  • Example models we deploy: 2GIG-FT1-345 / FT1e-345 (encrypted), IQ Flood-S for 319.5-MHz systems.


Compatibility Notes


  • Works with Alarm.com-enabled systems for mobile alerts, activity history, and automation (e.g., smart valve shutoff).

  • We’ll match the radio family (345 or 319.5 MHz, etc.) to your panel for seamless enrollment.


Popular Use Cases


  • Under kitchen/bath sinks, behind toilets, by water heaters, washers, or HVAC pans

  • Near sump pumps and low points where water accumulates

  • Vacation homes or unoccupied areas prone to freezing/leaks


Frequently Asked Questions


How fast will it alert me to a leak?


To prevent false alarms from splashes, the probe typically confirms water for about 3 minutes before signaling “wet.” You’ll get an alert, and the sensor reports “dry” once water clears for ~3 minutes.


What counts as “freeze”?


Many units report freeze when ambient temperature stays at or below 41°F (5°C) for about 5 minutes (and report a clear once above 41°F for ~5 minutes). We can also enable a high-temp alert (e.g., 95°F / 35°C).


Will it work with a smart water shutoff?


Yes—on Alarm.com, leak events can close a smart valve and notify you immediately.


Where should we place it?


At the lowest point near likely leak sources (under sinks, water heater base, washing machine pan). We secure the probe right at floor level for fastest detection.


What kind of water does it detect?


Fresh, tap, or salt water—the probe senses conductivity either way.


Ready to Catch Leaks Early?


Smart Shield Systems will specify the right Flood/Freeze Sensor, install and enroll it, and set up smart alerts/automations—so small leaks don’t turn into big repairs.
