4.1.9 Dedicated Annunciator Mode
This page allows the selection or deselection of “Dedicated Annunciator Mode” for
Triggers 1, 2 and 3. When enabled, this mode causes a separate discrete annunciator to
illuminate whenever the audio track for that trigger is playing. A particular installation could
include up to three dedicated pushbuttons for particular briefing tracks, background music,
etc, along with an annunciator to indicate when that trigger is active.
Press the button to toggle between “DEDICATED ANN.” (this mode is selected) and “NO
ANNUNCIATOR” (this mode is not selected). The factory default value is “NO
ANNUNCIATOR”.
Notes:
• The annunciator will illuminate whenever the associated track is playing, even if it
was not initiated by the discrete trigger. For example, if a “Prepare to Land”
briefing track is tied to Trigger 1, the Trigger 1 annunciator will illuminate even if
the track is selected from the DMP-200 front panel.
• The BUSY output is redefined as TRIG1_ACTIVE and the CHIME output is
redefined as TRIG2_ACTIVE when this mode is selected.
4.1.10 Test External Outputs
This page allows the installer to cycle through all the DMP-200 external outputs, setting
and clearing each one in turn. This function is used during the installation checkout
procedure, and may be used any time an external output needs to be tested. Each press
of the button will activate one output and clear all others. The “All OFF” selection turns off
all outputs.
4.1.11 Test External Inputs
This page allows the installer to test the three external trigger inputs and the external
Play/Pause input. The display shows which input, if any, is currently active. If more than
one input is active, the display will show only the highest priority input. Play/Pause is the
highest priority, followed Triggers 3 through 1 in descending order.
If an input appears to have the wrong polarity, be sure the active levels are set correctly
(see page 11 for more information on setting active levels for inputs).
5.0 Installation Checkout Procedure
After all wiring is double-checked, especially the power and ground connections, the following
procedure should be performed to verify external connections:
