Freeze Alarms and all of our other alarm dialer units require a phone line. However this phone line does not have to be a classic analog style land line. As a general rule of thumb, if your phone service has an RJ11 (normal phone jack) jack which you can plug a normal telephone or fax machine into and they will operate than any of our alarm dialers will also work on your phone service.

    The Freezealarm dialer does not seem to work with AT&T uverse systems. What is the solution?

      Hi, I’m sorry but we’re never sure how the dialers will interact with every type of phone system available now. If you have a phone jack that you can plug a fax machine or a regular telephone into than the Freeze Alarm should work.
