Cockpit Door Surveillance System
The following notes are from the Maintenance Manual
The Cockpit Door Surveillance System (CDSS) allows the pilot and copilot to view video images of the area outside the Cockpit Door through a video monitor mounted on the centre console panel between the flight crew. Power to the CDSS system is controlled from an On-Off push-button switch located on the overhead panel.
Viewing camera selection is performed by touching the monitor screen to activate a selection menu and then touching the screen icon corresponding to the desired camera. The monitor screen goes blank after a pre-defined time period. Monitor brightness control is effected by repeatedly touching the desired brightness control icon on the screen. The CDSS System consists of the following components:
- One LCD monitor in the cockpit.
- Three wide angle viewing cameras with integral light for viewing in darkness.
- System control unit.
- On-Off switch on the overhead panel.
- cabin ready switch located adjacent to Door L1.
The CDSS allows the pilot and copilot to view video images of the area outside the Cockpit Door through one video monitor situated forward of the thrust levers. Power to the CDSS (L 28V DC BUS) is controlled from an On-Off pushbutton switch labelled CDSS located on the Overhead Panel. When selecting the system off, the top half of the switch illuminates OFF in white. When selecting the system on, the OFF light extinguishes and the switch is not illuminated. If a system fault exists, FAULT illuminates in amber on the bottom half of the switch. Viewing camera selection is performed by touching the monitor screen to activate a selection menu and then touching the screen icon corresponding to the desired camera. Monitor screen display is turned on by touching the screen where there is no icon. An automatic feature exists where a time, in seconds, can be input and the camera view will automatically shift between cameras. Monitor brightness control is effected by repeatedly touching the desired brightness control icon on the screen.
The CABIN READY feature allows the cabin crew to indicate to the cockpit that the cabin has been prepared and secured for takeoff and landing. The CABIN READY switch located adjacent to the cabin attendant panel at door L1, illuminates green when pressed. This sends a signal to the Pilots CDSS Monitor, which then annunciates CABIN READY. Touching the monitor cancels the annunciation on the monitor and extinguishes the Cabin Ready Switch in the cabin.
