The CV2 is a rugged, industrialized Alarm Dialer that connects to any North American cellular network (see coverage map). It is setup in the same way as the Protalk Plus below except that it also has the ability to accept analog inputs. To setup the CV2:

  • Connect digital alarm inputs
  • Record voice alarm messages
  • Set phone numbers

When an alarm occurs, the Protalk CV2 automatically dials the Callout numbers in its directories, and annunciates the alarm in a clear, toll-quality recorded voice. The user can then acknowledge the alarm via touch tone keys. If an acknowledge code is not received, the Protalk CV2 keeps dialing through its stored list of telephone or pager numbers until the alarm is acknowledged. All input and output status can then be interrogated so that the appropriate action can be taken. Relays can also be operated remotely by entering codes from your telephone.
