ATEIS - IDA8

130

Mode:

There are two types:

1. 25V/70V/100V

An Audio signal through the amplifier and back to the IDA8C/S.

2. 0dB

Instead of going through the amplifier and back to the IDA8C/S, the audio will output to other
equipment and monitoring is disabled under this mode.

Tolerance(%):

Specifies the tolerance of impedance to detect a bad impedance fault. For example, if the
reference is 1000 ohm and the tolerance is set to 15%, the range of good impedance will be 850
~ 1150 ohm. If measured impedance value is 1300 ohm, a bad impedance fault is recognized by
the IDA8C/S.

Get Reference

When the system is constructed, the user needs to get the impedance value of the speaker for
further reference. This value will be utilized to detect faults of zones. The rule of fault detection is
described in preview item "Tolerance(%)".

Reset Reference:

Resets the reference value to empty, resulting in the disabling of zone monitoring, but the
measure value is still updated.

There are buttons on the right side of the page [Zone Settings]:

Get All Reference:

Get references for all zones.

Reset All Reference:

Resets references for all zones.

Reset Monitoring:

This will tell the IDA8C/S to reset the monitoring and to initialize the state of the devices. In the
case of zone short fault, the IDA8C/S will open the internal relay to stop the output of the audio
signal to speaker. After the relay is opened, the IDA8C/S has no way to know if the circuit
outside has a short or not. Therefore, after the user repairs the circuit, the user needs to reset
the monitoring to close the relay to the output audio signal to the speaker again so that the
IDA8C/S can monitor the short problem again.

Measurement:

After parameter settings are set in the grid at the lower part, the IDA8C/S starts to measure the
value which is received from the internal circuit, and displays it on the grid at the upper part of the
window:
