Dialer Operation - ADEMCO VISTA-32FB Installation And Setup Manual

VISTA-32FB Installation and Set-Up Guide
DO NOT connect both outputs to the same telephone company line.
•
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 .

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.
