Can I use a Freeze Alarm with my phone system? What type of phone systems do Freeze Alarms require?
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.
