4.0
System Operation
4.1
Communicator Operation
The FPT-DACT contains an integrated communicator
that sends reports to a monitoring station. The
communicator operates automatically.
When events occur, the communicator sends
corresponding reports to the monitoring station by
priority according to NFPA requirements. Fire and
waterflow alarms are sent first, followed by supervisory
alarms and trouble reports, and finally by all other
reports.
4.1. 1
Phone Line and Phone Number Selection
To comply with UL and NFPA standards,
program both a primary and an alternate
telephone number. The numbers must be
different.
The FPT-DACT can report to two telephone numbers
with full single, double, and backup reporting. It
communicates in Modem IIIa
4/2 formats.
To verify the delivery of critical reports, the FPT-
DACT can report over two telephone lines. Reports can
be directed to one or both of the two telephone numbers
using the report steering feature in the FPT-DACT
programming. Account Number 1 is used with Phone
Number 1 and Account Number 2 is used with Phone
Number 2.
Except for Test Reports, the FPT-DACT
automatically selects the telephone line to
use.
Report Routing
The two ways reports are routed:
1. Reporting routing starts using Phone Number 1 on
Phone Line 1, unless the line monitor shows Phone
Number 1 to be bad at the start of reporting. If the
report fails on Phone Number 1 on Phone Line 1,
the FPT-DACT automatically switches and uses
Phone Number 2 on Phone Line 1.
2. If the report still fails on either telephone number
on Phone Line 1, the FPT-DACT tries to send the
report on Phone Line 2 using Phone Number 1. If
this fails, it tries Phone Number 2 on Phone
Number 1.
The exception to these options occurs when sending
Test Reports (Manual or Auto). Test Reports are sent to
alternating telephone lines regardless of telephone
monitor or initial failure to report, allowing you to test
both telephone lines when sending two Manual Test
Reports. The first report uses one line, the second uses

, Contact ID, SIA, and
the other line. Auto Test automatically alternates
telephone lines. You determine which telephone line to
use for testing purposes in Manual Test (Phone 1, Phone
2, or alternating telephone lines).
Refer to Table 5 for the complete report routing pattern.

Because the FPT-DACT automatically
selects which line to use, both telephone
lines must use the same dialing sequences
for reporting. For example, a telephone line
that requires "9" for dialing an outside line
cannot be paired with a line that does not
require a "9." The PBX lines and ground start
telephone lines do not comply with NFPA
requirements for digital communication.
When an Automatic Test Report is received
by the central station every other day, and
the FPT-DACT is configured to send a Test
Report daily, it indicates that one telephone
line at the protected premises is inoperative.
Correct this condition immediately because
other critical reports might be delayed (up to
48 h) while the dialer is attempting to send
the test signal through the inoperative
telephone line.
4. 1 .2
Telephone Line Supervision
While the communicator is idle, the FPT-DACT
monitors the primary and alternate telephone lines by
sniffing the line for trouble.
The FPT-DACT sniffs each line every 12 secs. When a
trouble still exists after three samples (36 sec), the FPT-
DACT sends a Trouble Report and activates the yellow
telephone line LED and system trouble relay.
