The control panel monitors the phone line for voltage only. If the voltage drops low enough (between 1 and 3 V)
for 40 sec, it declares a phone line fault. If the phone line voltage remains above 3 V for at least 40 sec, it declares
the phone line restored. See the ”Phone Line Fault Requires Reset” option in Phone Line Options on page 14.
When enabled, the Phone Line Fault event appears at all keypads for all areas. The control panel sends a Phone
Line Restore {100} report when a phone line fault event restores.

1. System detects phone line fail and puts Event {99} in the log.
2. System starts dialing attempts if programmed for Phone Fail report.
3. Phone line restores before Comm fail event.
4. System sends phone line fail and phone line restore reports.
If the phone line fails (as described above), but restores after a Comm Fail event:

2. System starts dialing attempts if programmed for Phone Fail report.
3. Dialing attempts end with Comm fail event, phone fail report is flushed.
4. System detects phone line is restored and puts restoral report in buffer.
5. System starts dialing attempts and sends phone fail restoral and Comm restoral reports.
If an alternate communication path is enabled, the control panel can send a Phone Line Fail {99} report via the
alternate communication path when a phone line fault event occurs.
