Phone Line and Phone Number/IP Selection
To ensure the delivery of critical reports, the fire panel has two phone lines and two phone
numbers or IP addresses that can be used for reporting. Reports can be directed to one or
both of two phone numbers or IP addresses using the Report Steering feature in the control
panel programming.
To program reporting selections:
–
By keypad, use shortcut 6-7 for PROGRAMMING-DACT (see
Shortcuts, page 91
and/or
Menu Structure, page 92
)
–
By browser, use the Reporting screen
Note that Account Number 1 is used with Phone Number/IP 1, and Account Number 2 is used
with Phone Number/IP 2. Except for test reports, the control panel automatically selects the
phone line or IP address to use. If the phone line monitor shows that a line is bad, when a
report is sent, it automatically picks up the other line. If the report is not successful after the
defined number of attempts on Line 1, the control panel automatically switches and uses
Phone Line 2. The one exception is when test reports (manual or automatic) are sent. Auto
test reports are sent every 4 hours to 28 days. Each time a test report is sent, the control
panel alternates phone lines. If the user sends two manual test reports, both phone lines can
be tested. With the default auto test interval of 24 hours, the automatic test uses a different
line each time.
Notice!
Report received every other time
If the central station receives the automatic test report only every other time, this indicates
that one phone line at the protected premises is inoperative. Correct this condition
immediately, because other critical reports can be delayed when the communicator is trying
to send the test signal through the inoperative phone line.
Because the control panel automatically selects which line to use, both phone lines must use
the same dialing sequences for sending reports. For example, a line that requires a "9" to be
dialed for an outside line cannot be paired with a line that does not require a "9". PBX lines
and ground start phone lines do not comply with NFPA requirements for digital
communication.
While the communicator is idle, the FACP monitors the primary and alternate telephone lines
by testing the line for trouble. The FACP sniffs each line every 12 seconds. When a trouble still
exists after three samples (36 seconds), the FACP sends a trouble report and activates the
yellow trouble LED and the trouble relay.
Although two independent phone lines are required for UL 864 Central Station service, the
FACP can be configured with one phone line if the communicator is used only for
supplemental reporting on a local, remote station or auxiliary system.
!
Warning!
Communicator reports can be delayed if the dialer outputs are not connected together on an
installation where the control panel has only one phone line.
Phone Line Attempt Matrix
The maximum number for panel reporting attempts is programmable (range 5 to 10 for each
line). When the programmed number of attempts is reached, the panel indicates a
communication failure for the destination.
If both destinations (accounts) are programmed to PSTN, the attempts occur according to the
table below.
