Enabling the Dialer Outputs
To enable the dialer outputs, entries must be made in field 3*30. Enter 1 in the
first entry space to enable Dialer 1 (main dialer). Enter 1 in the second entry
space to enable Dialer 2 (5140DLM backup dialer).
Supervision for the existing dialers is enabled in #93 Zone Programming mode
for zones 974 (Dialer 1) and 975 (Dialer 2).
Dialer Operation
When only the main dialer is enabled ([1,0] in field 3*30), the VISTA-100 will
attempt to route all calls over the main output. When both main and back-up
dialers are enabled ([1,1] in field 3*30), the VISTA-100 will attempt to route all
calls over the main output until a fault is detected, at which time it will attempt to
use the back-up 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 8
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).
The system will not switch to the backup dialer unless it detects a fault (low
voltage and low current) on the main telephone line. This means that if a report
does not go through on the main phone line due to a programming error, the
backup dialer will not be activated.
The VISTA-100 will transmit reports in the following order: alarms (fire,
medical/panic, burglary), fire supervisories and troubles, remaining types of
messages. See the
SYSTEM COMMUNICATION section for a description of
communication formats, the types of messages transmitted by the panel, and for
the dialer programming defaults.
