5. Turn “ON” the Internal Trouble Sounder.
6. Turn “ON” the RemoteTrouble Audible Output.
7. Turn “ON” a trouble location indicator, if appropriate.
If the TROUBLE ACKNOWLEDGE pushbutton is pressed, the internal trouble sounder and the
external trouble audible will be silenced. All other trouble indicators will still indicate a trouble
condition. The internal trouble sounder and the external trouble audible will resound for
subsequent trouble conditions. When there are no trouble conditions detected, the NORMAL
LED will always be “ON” and the TROUBLE LED will always be “OFF”. When a trouble condition
is detected, the NORMAL LED will always be “OFF” and the TROUBLE LED will always be “ON”.
The panel has trouble location LEDs, which provide information as to what trouble condition has
been detected, and on which part of the system the trouble is located. Figure 7-1 shows the
location of all trouble location indicators within the panel. Table 7-1 on Page 7-3 cross-references
the trouble location LEDs on the plug-in modules to the proper troubleshooting procedure. Table
7-2 on Page 7-3 addresses the LEDs on the MDX-2.
