4.1.2 Telephone Line Supervision
While the communicator is idle, the D9068P monitors the primary and alternate telephone lines by “sniffing” the line
for trouble.
The D9068P sniffs each line every 12 sec. When a trouble remains after three samples, 36 sec, the D9068P sends
a Trouble Report and activates the yellow phone line LED in addition the AX Series FACP will indicate a DACT
trouble condition.
The yellow telephone line LED indicates active communication and shows line fault conditions. It flashes once
every second during active communication. The LED(s) lights steadily for a line fault condition. All line faults are
reported and displayed on the AX Series fire alarm control panel.
4.1.3 Wait for Dial Tone
When enabled, the Wait for Dial Tone feature verifies a dial tone is present before dialing. When there is no dial
tone present after 7 sec, the D9068P hangs up and tries again after a 30-sec wait. When no dial tone is detected on
the second try, the D9068P dials again. When this feature is not enabled, the D9068P waits 7 sec after
disconnecting and then re-dials whether or not a dial tone is present.
4.1.4 Call
Routing
Each type of event (non-supervisory alarms, supervisory alarms, alarm restoral’s, supervisory restoral’s, test and
trouble, and trouble restoral’s) can be programmed with a different call routing. For example, the alarms messages
can be set for Phone 2 backup while supervisory restoral’s are sent to Phone 2 only.
Because the D9068P 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 D9068P 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.
Phone 2 Backup is the default and recommended setting for all event types. Changing this setting can
cause messages to transmit to the central station.
