Furnace Freeze Alarm

If a homeowner is away from home this "Furnace Freeze Alarm System" will call the number programmed and leave a message that the temperature in your home has dropped below 45 degrees.

It plays a recorded message and continues to do so until the call is acknowledged, and even during a power outage. This allows the Homeowner to take action to prevent the home from reaching freezing temperatures. I have also noticed that the install instructions are available on the website and very easy to follow

A new 9V Energizer Battery is included. I am asking $20.00 cash.
