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.
