1 Number of Rings
This option determines the number of rings detected on the line before the on-
board communicator answers.
2 Line Fail
The Galaxy 16 plus communicator continually monitors the telephone line that it
is connected to. This option allows the engineer to determine the line monitor-
ing conditions that result in a Line Fail event being reported and recorded in the
log.
The three line monitoring capabilities are:
1. Line Volts:
A line fail occurs if the voltage on the telephone line falls below three
volts.
2. Dial Tone:
A line fail occurs if the communicator cannot detect a dial tone on the
telephone line.
3. Pre Dial Ringing:
A line fail occurs if the communicator attempts to transmit an alarm while
there is an incoming call.
When one of these conditions is detected, a Line Fail message is sent to the
Galaxy 16 plus and is stored in the Event Log. If the system is unset, the
TELECOM FAILURE message appears on the keypad display and a local alarm
is sounded. If the system is set (Full or Part) when a line fail condition occurs,
the message TELECOM FAILURE will be displayed when the system is unset,
this will be accompanied by a local alarm.
The local alarm is only activated for the first line fail condition of each unset
period. Subsequent line fails are displayed as TELECOM FAILURE messages on
the keypad for the duration of the condition and are recorded in the event log.
If an alarm occurs during a Line Fail condition the Bell Delay is overridden.
