5. Operation

Once the K-202-DVA is properly installed and programmed, it operates automatically. Ensure the NORM / PROG switch is set to NORM for normal operation.

5.1. Triggering Announcements

When an input (INPUT 1 or INPUT 2) is activated by a connected device or sensor, the K-202-DVA will initiate its pre-programmed sequence. This typically involves:

Dialing the pre-programmed telephone numbers.
Playing the associated voice message for the activated input.
Repeating the message or dialing sequence as configured during programming.

5.2. Adjusting Volume

Use a small screwdriver to carefully adjust the VOLUME potentiometer on the unit to achieve the desired announcement volume.

6. Programming

The K-202-DVA requires programming to define the telephone numbers to dial and the voice messages to announce for each input. Refer to the detailed programming guide (often provided separately by Viking Electronics or available on their website) for specific steps. Generally, programming involves:

Switching the NORM / PROG switch to PROG.
Connecting a telephone or programming device to the unit.
Following a sequence of button presses or voice prompts to record messages and enter phone numbers.
Adjusting settings like dial attempts, message repetition, and input sensitivity (possibly using LEARN INPUT SENS).
Switching the NORM / PROG switch back to NORM after programming is complete.

Periodically test the system to confirm proper operation, especially for emergency notification applications.

8. Troubleshooting

If you encounter issues with your K-202-DVA, try the following troubleshooting steps:

Problem	Possible Cause	Solution
Unit does not power on.	No power, incorrect power supply, faulty connection.	Verify 12 VDC power supply is connected and functional. Check power outlet.
No dialing or announcement when input is triggered.	Unit in PROG mode, incorrect wiring, no phone line, programming error.	Ensure NORM / PROG switch is in NORM. Check input wiring. Verify phone line connection. Re-program the unit.
Voice announcement is too quiet or distorted.	Volume setting too low, poor recording quality.	Adjust the VOLUME potentiometer. Re-record the voice message if necessary.
Unit dials but no message is heard.	Message not recorded or corrupted.	Re-record the voice message for the corresponding input.

If the problem persists after attempting these solutions, contact Viking Electronics technical support.
