Frame Alarm
A separate alarm system is used to monitor the frame components other
than the Maestro Processor.
Frame alarm conditions are: frame fan failure, frame power supply failure,
or Concerto Matrix Controller module Reset.
Pinouts for the 9-pin D “Alarm” connector on the lower rear frame panel
are shown in
Table 7 .
Table 7. Alarm Pinouts
“Alarm 1” is generated by Matrix Controller board 1, which is located in the
top controller slot. “Alarm 2” is generated by the redundant controller in
the bottom slot (if present).
The location of this connector is shown on page 87 .
The power supply alarm condition is also indicated by a red LED on the
front of the supply.

indicator labeled “ALM.” This LED will be turned on for any of the fol-

• Receiving a command from the Control Panel Server to turn the alarm
LED on.
In addition to the above, the Source Control panel has two additional red
LEDs labeled “PS1” and “PS2”. These LEDS will be turned on if the corre-
sponding DC-DC converter modules indicate a power fault.
The Maestro hardware control panel tub includes a SMPTE-type Alarm
BNC that will indicate and alarm for any of the above conditions. In addi-
tion, the Alarm BNC will indicate an alarm condition if the Control Panel
