About the ProTalk Cv3

The ProTalk Cv3 is a device used to notify an end user of alarm conditions at an unattended local or remote site.

Alarm conditions are defined by the user and can include such things as pump failures, tank levels and pressure changes. Inputs can be defined as alarming or monitor only, allowing you to define which changes are most critical and require immediate notification.

When an alarm condition occurs, the ProTalk Cv3 will announce the alarm using the internal cellular module. The unit will continue to call out using the predefined directory until such time as the alarm is acknowledged.

The B1277 ProTalk Cv3 is very versatile and can be programmed to perform many more functions at the discretion of the user. It can:

  • announce alarms over telephone, text, radio, PA, email or any combination thereof.
  • be programmed to send coded tones along with the voice messages to activate such devices as radio pagers, relay and annunciator panels.
  • perform remote control functions using the 4 relay outputs automatically or by receiving user defined DTMF codes.
  • use up to 4 alarm groups and shifts to create custom directories based on common alarms or time of day.
  • email a daily activity summary report to notify you of all recorded activity
  • email and/or text notifications when alarms are announced, cleared and/or acknowledged (for informational purposes only).
  • email, text and/or phone regular status reports including alarm status and enabled point values
  • define security levels for incoming calls and text messages.
  • require an access code for phone or text access to programming.
  • interact with you in French (limitations apply, contact us for details).
  • be installed in hazardous locations requiring Class I, Div 2 rating.
  • function in extreme temperatures of -40°C to +60°C (-40°F to 140°F).

The ProTalk Cv3 is the industry standard in cellular alarm dialing and SMS notification and is designed to operate in urban, rural and remote sites across North America.
