Freeze Alarm models FAI and FAD2 and all Sensaphone dialers work well with voice mail and answering machines. If you have voice mail or an answering machine at your dialer location, messages can be recorded and retrieved as normal. As well you can access your Freeze Alarm through a simple procedure of calling, hanging up and calling back. If the Freeze Alarm or Sensaphone is calling locations that have voice mail or answering machines, all or a portion of the alarm message will be recorded.
