You are always connected and in control with the Cv3. With the touch of a button from any touch-tone phone, you can acknowledge voice alarm messages, control relay outputs, interrogate the status of any sensor input, and make programming changes. As an added convenience, SMS text messages can be sent directly to your cell phone. New wiring and configuration software makes installation and set-up quick and easy!

Protalk Plus

The Protalk Plus is a rugged, industrialized Alarm Dialer that connects to a regular RJ-11 phone line. To setup the Protalk Plus to monitor a remote site:

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

When an alarm occurs, the ProTalk Plus 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 Plus 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.
