General Information
The VISTA-128B provides one main built-in dialer for communication to the central station.
The communicator will make up to 8 attempts to transmit a report to one or both telephone
numbers, depending upon the report routing option programmed. The control panel will
transmit reports in the following order: alarms (fire, medical/panic, and burglary), remaining
types of messages.
Telephone Line Connections
Connect the main dialer output to telephone company lines which provide loop start service
using the RJ31X cables supplied. Do not connect to telephone company lines which provide
ground start service.
TERMINALS
ON CONTROL
•
To prevent the risk of shock, disconnect phone lines at telco jack before servicing the panel.
•
If the communicator is connected to a telephone line inside a PABX, be sure the PABX has a
back-up power supply that can support the PABX for 24 hours (Central Station usage) or 60
hours (Remote Station usage). Many PABXs are not power backed up and connection to
such a PABX will result in a communication failure if power is lost .
The telephone line inputs have overvoltage protection in accordance with UL1459 as specified in
U L
UL985/UL1023.
