The Chatterbox uses voice synthesis to report up to 32 on/off switch conditions and one analog condition via a standard telephone line. When an alarm is detected , the Chatterbox automatically dials up to 8 phone numbers, and then the user programmable messages tell you the exact nature and location of the alarm call.And you can call the Chattebox at anytime from your phone to hear a complete report of your monitors alarm status. We have these at our pump stations to warn us of flow and pump issues as well as power failures etc. They were in working order when recently replaced with a different system but are used and sold as is.
