OPERATION
Normal operation of the ICS-22 speaker panel only requires the front
panel controls. For intercom operation, set the intercom level control to
the desired level and press the talk button when talking. If a headset or
handset is used, set the sidetone control for each channel for the
desired amount of sidetone in the earphone. If the PT-4 hand-held,
push-to-talk microphone is used, or if the panel microphone is used,
set the sidetone controls for minimum feed-through to the speaker to
prevent acoustic feedback.
ECS System Configuration for ICS-22 Panels
The Eclipse Configuration System (ECS) software does not directly
support the ICS-22 speaker panel. In order to configure an ICS-22
panel the port is configured to drive an ICS-1008 panel with 14 keys (7
pairs of buttons). The two ICS-22 selectors are mapped onto the
ICS-1008 keys starting from the left. Only the leftmost two pairs of
keys on the ICS-1008 can be used to program the ICS-22; any other
keys on the ICS-1008 will have no effect.
There must be a corresponding listen key on the top row to the talk key
on the bottom row of the ICS-1008 configuration for the ICS-22 panel
to work correctly. If a talk key only is configured on the ICS-1008 in
ECS the Talk key on the ICS-22 will not latch.
It should be noted that the panel signalling and control protocol used
by the Eclipse matrix differs from the Matrix Plus 3. As a result the
operation of these panels with an Eclipse matrix may be slightly
different to their operation with a Matrix Plus 3.
