at premises receptacle on the VIS-4. Connect
the other end of the cable to the phone
connection to the whole premises.

Testing
1. On power-up the unit is in Digital Voice Mode.
The LED should start flashing within a few
seconds of powering up (Figure 3).
2. The VIS-4 will automatically switch to DAS /
Intercom Mode when the Local Digital Voice
Service power is disconnected.
3. When the DAS / Intercom rings and the Digital
Voice line is on hook, the VIS-4 will switch to
the DAS / Intercom. After answering the
intercom or the ringing has stopped, the VIS-4
will switch back to Local Digital Voice Service
mode.
4. To answer the DAS / Intercom when the
Digital Voice line is in use, press the flash
hook switch momentarily, this will hold the
Digital Voice line and at the same time switch
the VIS-4 to DAS / Intercom mode.
5. When finished with the DAS / Intercom call,
press the flash hook switch momentarily to
recover the Voice line. In some case the flash
switch may need to be activated twice to
recover the voice line.
6. The VIS-4 is programmed to switch to Digital
Voice Mode when not in use.
7. To test the VIS-4 switch to DAS / Intercom in
the event of power loss on the Voice service,
pull the RJ-11 plug from the Voice service
jack. The VIS-4 will switch over to the
Intercom side within a few seconds.
DIAL DOWN FEATURE TEST
1. Lift the hand set of the local phone. You will
hear dial tone from the Local Digital Voice
Service.
2.
Dial “#” on the phone. While dialing this code,
ignore voice messages from the voice phone
service. As soon as the proper dialing
sequence is completed, the VIS-4 will switch
to the DAS / Intercom line. Dialing the code
must commence within 5 seconds of going off
hook, after that the Dual Tone Multi-frequency
detection chip function is disabled.
3. Dial out desired function numbers on the
Intercom line. The VIS-4 will switch back to
Voice service as soon as you hang up the
phone or activate the flash button.
