CDSS DESCRIPTION AND OPERATION

1. General

The purpose of this modification is to allow the flight crew to monitor the cabin area immediately aft of the cockpit door without opening the locked cockpit door to prevent unauthorised entry into the cockpit.

This Cockpit Door Surveillance System (CDSS) consists of three cameras in the forward cabin near the flight deck door, one video monitor on the aft bulkhead of the cockpit, a control panel and the associated wiring to connect these components together (see Figure 1). Some CDSS Systems include a System Active Indicator, which is mounted in the ceiling panel adjacent to the R1 Door Camera. The CDSS is connected to DC Bus 2 and isolated by a 2.5 amp circuit breaker. It is independent from all other aircraft systems.
