This popular model calls up to 3 phone numbers and alerts you with a voice message if the temperature gets too low(or too high), if the power goes out for more than an hour, or if the back-up battery needs replacing.
Enjoy peace of mind with the Intermediate model because you can call your FreezeAlarm from any phone in the world and check the current temperature, find out if the power is on or off in your home or cabin, and even check the voltage of the back-up battery. You can also change the settings and phone numbers remotely
