Ideal for homeowners who go on business trips, vacations, own a second home, or live in areas that go below freezing. Helps avoid frozen and broken pipes. Simply plug the telephone into the Home Freeze Alert, plug the Home Freeze Alert into the telephone wall jack, and test the telephone for a dial tone. The homeowner just calls their home - if the phone rings the temperature is above 42, if they get a tone their heat has dropped below 42 and they should contact a designated person to repair the system before pipes freeze and break. Carded.
