Automated Voice Message Delivery System. Model K-6000-DVA can automatically notify up to 1000 people of an event or an event cancellation, school or business closing or delayed opening. The K-6000-DVA is designed to connect to a standard analog CO line, PABX station or VoIP ATA or FXS port. To activate the unit, an authorized official calls the K-6000-DVA, dials a 6 digit access code, selects a pre-recorded message or records a live message up to 1 minute, then activates the unit via a touch tone command to automatically call all the phone numbers in a pre-programmed group. Up to 6 groups of phone numbers can be pre-programmed into the unit. Alternatively, activating an All Call command calls all pre-programmed numbers. The K-6000-DVA can also be activated (or cancelled) by up to 8 external momentary push buttons (not included). In the event any called number is busy or doesn t answer, the unit will retry the unanswered numbers several times (programmable 1-9) after all other numbers are called. The maximum number of rings before calling the next number is programmable 1-8 rings (6-48 seconds). The unit waits 2 seconds for touch tones after the message is delivered, if a is detected, the message is replayed once. For critical applications, the K-6000-DVA can be programmed to require a positive confirmation - the called party must send a pre-determined touch tone to confirm that the message was received. The K-6000-DVA can be programmed from your PC s USB or RS-232 port.
