Why does a line need recalibration in Siemens Fire Alarms?
If a line must be recalibrated in Siemens Fire Alarms, it is because the line topology and/or configuration parameters have been changed in a way that affects the power consumption of the line. Recalibrate the line to solve this issue. You will find more information on this in chapter 'Manual line calibration [? 60]'.
What to do if power consumption of the line (maximum) fails in Siemens Fire Alarms?
When the power consumption of the line (maximum) fails in Siemens Fire Alarms, it may be due to too many line devices connected to the line card, or the configured settings for the 'Sounder volume' and 'Beacon intensity' properties may be too high. In such cases, you should reduce the sound level of the alarm sounder or the intensity of the beacons on the affected line card. You will find information on the configuration of the sound level of the alarm sounder or the intensity of the beacons in document A6V10210424.
What to do if power consumption of the line (nominal) fails in Siemens Fire Alarms?
If the power consumption of the line (nominal) fails in Siemens Fire Alarms, it could be caused by having too many line devices connected to the line card, or the settings for 'Sounder volume' and 'Beacon intensity' being too high. To resolve this, reduce the sound level of the alarm sounder or the intensity of the beacons on the affected line card. You will find information on the configuration of the sound level of the alarm sounder or the intensity of the beacons in document A6V10210424.
What to do if the power consumption of the line card fails in Siemens Fire Alarms?
If the power consumption of the line card fails in Siemens Fire Alarms, it may be because too many line devices are connected to the line card, or the configured settings for the 'Sounder volume' and 'Beacon intensity' properties are too high. To fix this, reduce the sound level of the alarm sounder or the intensity of the beacons on the affected line card. You will find information on the configuration of the sound level of the alarm sounder or the intensity of the beacons in document A6V10210424.
What causes tolerance of the line resistance to fail in Siemens Fire Alarms?
If the tolerance of the line resistance fails in Siemens Fire Alarms, it may be due to the conductor cross-section being too low for the laid length of the line, faulty wiring between two line devices, too many line devices connected to the line card, or the configured settings for the 'Sounder volume' and 'Beacon intensity' properties being too high. To solve this, check the operating voltage of the individual devices in the calibration report, or reduce the sound level of the alarm sounder or the intensity of the beacons on the affected line card. You will find information on the configuration of the sound level of the alarm sounder or the intensity of the beacons in document A6V10210424.
