Indicates a row is refer to which zone.
Monitor
Enable/Disable zone monitoring, if monitoring of a zone is disabled, IDA8C/S will not detect
faults of zone.
Backup
This setting tells IDA8 if backup amplifier can service the zone or not. i.e. if the checkbox is not
checked, when a fault of normal amplifier IDA8C/S will not switch to backup amplifier for the
zone, result to the monitoring of the zone is not working.
Mode
There are two choices:
1. 25V/70V/100V
Audio signal go through amplifier and back to IDA8C/S.
2. 0dB
This mode the audio is output to other equipment, not go through amplifier and back to
IDA8C/S. Monitoring is disabled under this mode.
Tolerance(%)
Specify the tolerance of impedance to detect an bad impedance fault. for example if the
reference is 1000 ohm, tolerance set to 15%, then the range of good impedance will be 850 ~
1150 ohm, if measured impedance value is 1300 ohm, a bad impedance fault is recognized by
IDA8C/S.
Get Reference
When system is construction, user need to get the impedance value of speaker for further
reference, this value will utilized to detect fault of zones. The rule of fault detection is described
in preview item "Tolerance(%)".
Reset Reference
Reset the reference value to empty, result to disable zone monitoring. but the measure value
still updated.
There are buttons in the right side of page [Zone Settings]:
Get All Reference
Get reference for all zones.
Reset All Reference
Reset reference for all zones.
Reset Monitoring
This will tell IDA8C/S to reset monitoring, to initial state of device. In the case of zone short
fault, IDA8C/S will open the internal relay to stop output audio signal to speaker. after the relay
is opened, IDA8C/S has no way to know if the circuit outside is short or not, so after user repair
the circuit, it needs to reset monitoring to switch relay close to output audio signal to speaker
again, then IDA8C/S can monitor the short problem again.
