Troubleshooting
The calculated difference to the current
line resistance is ≤0 Ω. In an alarm
scenario, individual devices may fail if a
cable break occurs at the same time
and/or a thermal drift increases the line
resistance.
●
The conductor cross-section is too
low in relation to the laid length of
line.
●
Faulty wiring between two line
devices.
–
Check the operating voltage of
the individual devices in the
calibration report.
●
Too many line devices are
connected to the line card.
●
The configured settings for the
'Volume' and 'Beacon Intensity'
properties are too high.
–
Reduce the sound level of the
alarm device or the intensity of
the beacons on the affected
loop. You will find information on
the configuration of the sound
level of the alarm sounder or the
intensity of the beacons in
document A6V10450595.
