What is a Cellular Freeze Alarm?


A freeze alarm is a device that monitors the temperature inside your home and sends out a warning to you if the temperature drops dangerously low — before your pipes freeze and burst.  A cellular freeze alarm uses a cellular telephone signal to send out the alerts, whereas traditional freeze alarms communicate via a landline phone connection and Internet/WiFi freeze alarms communicate via the Internet.

Just a few years ago, you needed to combine a traditional freeze alarm with another piece of equipment called a “cellular terminal” to create a home freeze alarm that communicates via a cellular signal. Today, you can opt for one of these standalone cellular freeze alarms that are simple to install and less expensive to buy and operate.


Advantages of a Standalone Cellular Freeze Alarm


1.  Low cost to operate – No need for a landline phone or 24/7 Internet service to support your freeze alarm.

2.  Monitor from your smartphone, tablet or computer – Receive freeze alarm alerts wherever you are as a text message, email and/or phone call (depending upon which model you pick).

3.  Easy to set up – Just plug it in!

4.  Portable – If you move around a lot and want to use your cellular freeze alarm in various locations, just unplug it and bring it with you.

5.  Adjustable temperature set points – You program the high and low temperature thresholds.

6.  Monitor for power outages, heat and other conditions – The freeze alarms shown here also monitor for power outages and high temps. Add optional sensors to monitor for other conditions, including water leaks or humidity.
