General
Use the cabin system control panel (CSCP) to do the cabin test for the passenger service system (PSS).
See the cabin services system (CSS) section for more information about tests (SECTION 23-39).
Quick Test
Use quick test to quickly find major faults. This test does a check of these PSS components:
*
Passenger address/cabin interphone (PA/CI) controller
*
Cabin system management unit (CSMU)
*
Zone management units (ZMUs)
*
Overhead electronics units (OEUs).
This test collects continuous monitor data for as long as 20 seconds. The CSCP shows the failures.
To start a quick test, touch START QUICK TEST.
All Test
Use all test for a more complete test. All test starts a complete BITE of the system. The screen shows all the failures the BITE finds.

CABIN SERVICES SYSTEM -INTRODUCTION
General
The cabin services system (CSS) is an integrated system that combines these systems:
*
Passenger address
*
Cabin interphone
*
Passenger service
*
Cabin lighting
*
Monitor and control.
Passenger Address System
The flight crew and cabin attendants use the passenger address system (PAS) to make announcements to the passengers. The PA audio goes to speakers in the passenger cabin.
Cabin Interphone System
The flight crew and cabin attendants use the cabin interphone system (CIS) to speak with each other. They use handsets in the cabin and flight deck.
Passenger Service System
Passengers use the passenger service system (PSS) to control reading lights and to call attendants. The PSS also controls the passenger information signs.

Cabin Lighting System
The cabin lighting system (CLS) controls the passenger cabin illumination.
Monitor and Control Functions
The CSS has interfaces with other airplane systems for different functions. Flight attendants use CSS control panels to select monitor and control functions. These are some of the CSS monitor and control functions:
*
Cabin temperature selection
*
Potable water status
*
Cabin door status.
