Home Security Systems: What You Need To Know About Freeze Sensors

Freeze sensors are small devices which detect low temperature conditions in the home and provide early warning of this. These are ideal for homes situated in cold climate regions where temperatures could drop to below freezing point at certain periods of the year.

The primary purpose of freeze sensors is preventative. Freezing temperatures make water inside the pipes harden and expand, causing the pipes to freeze and then to leak or burst which, in turn, can result to flooding, problems with the plumbing and water system, or even structural and electrical damage, especially in older houses.

Repairing burst or frozen pipes can be very tedious and costly, requiring the services of plumbers and contractors. Investing in a freeze sensor then can warn of and prevent household freezing which saves the homeowner a large amount of money which would otherwise be spent on expensive repairs. The sensor can also warn of other issues such as a malfunctioning furnace.

The freeze sensor has a bimetallic thermal switch which is connected to a built-in transmitter ( When the temperature dips to below 41-45 degrees Fahrenheit, the freeze sensor is triggered, setting off an alarm which prompts the homeowner to adjust the temperature before it drops further to a criticallylow level. The sensor also transmits a restore signal when the temperature climbs back to 55-60 degress Fahrenheit.

If linked with a monitoring plan, the homeowner will be alerted of low temperature events andof restored signals via call, text or email.

Complementing the freeze sensor is the remote thermostat control which is sold separately or integrated in home energy management systems — permitting the homeowner to changetemperature settings inside the home even when they are away through mobile devices.

The freeze sensor should be installed in areas of the home which are susceptible to low temperatures such as near a furnace or exposed pipes. It is best installed on an interior wall where there is no air movement.
