Keep Your Home Protected From Water Damage and Frozen Pipes

Keep your home protected from water damage and frozen pipes with the Ecolink Flood/Freeze Sensor, 319.5 Mhz. This flood/freeze sensor alerts you when it detects water in a monitored area or when the temperature drops below 41F° (5°C). It has a flat, simple design that allows for easy placement in high-risk areas such as under a sink, toilet, hot water tank, or near water supply lines in unheated locations like basements, attics, and kitchen cabinets. As soon as water or an extreme temperature drop is detected, the sensor will transmit an alarm, notifying you of an event that can cause expensive repairs due to a flood or frozen pipes. The Ecolink Flood/Freezer Sensor is compatible with Qolsys, GE, and Interlogix receivers and can work with other systems utilizing the 319.5 Mhz frequency.
