Dialer Operation

When only the main dialer is enabled ([1,0] in field 3 30), the VISTA-32FB will attempt to
route all calls over the main output. When both main and backup dialers are enabled ([1,1]
in field 3 30), the VISTA-32FB will attempt to route all calls over the main output until a
fault is detected, at which time it will attempt to use the backup output. Line faults will
result in a zone 974-DIALER 1 FAULT or a zone 975-DIALER 2 FAULT display. The
communicator will make up to eight attempts to transmit a report to one or both telephone
numbers, depending upon the report routing option programmed. After the eighth attempt,
the communicator will hang up and a COMM FAIL will be displayed at the keypad. The
number of dialer attempts are programmed in field 3 21 (default = 8; must be restricted to 3,
4, or 5 attempts if a secondary phone number is programmed).
Periodic test reports will be alternated between the main and back-up telephone lines in an effort
to continually use and check both lines.
The VISTA-32FB will transmit reports in the following order: Alarms (fire, medical/panic,
burglary), Fire Supervisories and Troubles, remaining types of messages. See Section 26:
System Communication for a description of communication formats, the types of messages
transmitted by the panel, and for the dialer programming defaults.

To prevent the risk of shock, disconnect phone lines at the telco jack before servicing the
panel.
If the communicator is connected to a telephone line inside a PABX, be sure the PABX has a
backup 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 .
