Installation and Operator’s Manual

The CTL45M has the same operation as the crew controller, except this controller cannot make
public address announcements. The CTL45M has an ICS CALL button to alert the crew that the
observer positions(s) want to be on the intercom with the crew.
3.10.1.1 Intercom Operation, Two Control Heads (Pilot, Mission)
In this configuration, the pilot and copilot crew positions have one control head (CTL45P) and
the Mission personnel have another, CTL45M.
• System defaults to ALL -ALL at power up.
• Either panel can select ISO, and be removed from the intercom.
• The crew panel can select CRW, and place their panel in Crew mode, while the observer
audio controller is forced to ISO.
• The crew panel can select ALL and add everybody to the intercom.
• The Mission Observer panel can select ISO, and then select ALL, unless a crew panel has
selected ISO or CREW. If the crew audio controller has selected ISO or CRW, the mission
observer panel must use the intercom CALL function to be added to the intercom
3.10.1.2 Intercom Operation, Three Control Heads (Pilot, Copilot & Mission)
If three control heads are used, the following rules apply:
• System defaults to ALL-ALL-ALL at power up.
• Any panel can select ISO, and be removed from the intercom.
• Either pilot or copilot panel can select CRW, and place both panels in Crew mode, while
the observer audio controller is forced to ISO.
• Either pilot or copilot panel can select ALL and add everybody to the intercom.
• The Mission Observer panel can select ISO, and then select ALL, unless a pilot or copilot
has selected ISO or CREW.
With the CTL45M installed, the observer/mission personnel can isolate their audio feed from the
crew by pressing the ICS button. When the CTL45M is in ISO mode, the observer/passengers
will have intercom among themselves, and be able to use the selected radios.
If the flight crew selects ISO or Crew modes, the CTL45M will automatically enter the ISO mode,
and will not change modes unless the crew changes their state. If the observer personnel desire
to communicate with the crew, pressing “CALL” will activate an ICS call light and a chime in the
crew headsets.
3.11 Alert Audio
The PAC45 incorporates an independent alert audio system that can store three audio messages
recorded by the user, and played back when triggered by an external source.
Once triggered, the alert audio will continue until the ACK button (front panel or external) on
the CTL45 control panel is pushed, or the trigger input returns to normal. Edge-triggered alerts
will play 3 times or until ACK is pushed, whichever occur first.
3.11.1 Storing Alert Audio
The PAC45 systems can store three audio alerts. You must record all three when the unit is in au-
dio program mode. You cannot change only one at a time. If you wish to replace just one mes-
sage, we recommend you write down all the messages before starting the procedure.
To record messages from the pilot’s headset:
1. Press & Hold “ACK” until a chime is heard in the headset, and then release the
button.
2. COM1 will blink, to indicate the recording of ALERT #1.
3. Start speaking message.
