TELEPHONE LINE FAULTS
The telephone line to which the system is connected is
continuously monitored for line break or “line fault”
conditions which could affect the integrity of the System.
If a telephone “Line fault” occurs during the Alarm Unset
(Daytime) period, the keypad bleeper, and any other
internal bleepers/sounders connected in the system, will
operate to warn the user of this condition, and the
Keypad will display:
The user can cancel the audible warning by entering
their normal ‘x’ digit user code, whilst the keypad will
continue to display the Line Fault condition.
If the “Line fault” condition is still present when the user
requires to set the system, the display will show:
The system can still be FULL or PART SET by the user but
will function as an audible (bells only) system. The alarm
activation in this instance will not be reported to the Alarm
Receiving Centre
