(3) Operation of Passenger Lighted Signs
(a)
Energization Energization of the lighted signs system is as for CIDS Energization .
(b)
Operation of NO SMOKING/EXIT Signs All NS and EXIT signs are switched on under any of these conditions:
-Flight compartment NO SMOKING switch in overhead panel is switched to ON.
-Excessive aircraft decompression, irrespective of the NS switch position.
-Landing gear down and locked when the flight compartment NS switch is in the AUTO position.
(c)
Operation of FASTEN SEAT BELT/RETURN TO SEAT Signs The FSB and RTS lighted signs in the cabin and lavatories respectively are all switched on under any of these conditions:
-The flight compartment FASTEN SEAT BELT switch in overhead panel is switched on,

-The FSB signs are also activated in the event of excessive aircraft decompression, when the FSB switch is in AUTO or OFF position. The RTS signs are not illuminated during this event.
(d) General Operation Information The PAX lighted signs are deactivated in the event of an aircraft emergency.
(4) Lighted Signs System Testing and Programming (testing is not applicable for LED cabin signs) The fault status of the lighted signs is stored in the director BITE memory and is examined with the PTP. The CAM data which define the lighted signs system characteristics can be changed. Also additional functions which use the panel can be activated.

(2) System Description The equipment interface to the directors via DEUs A as follows: - one passenger call pushbutton and the seat row numbering light at
each passenger seat row, - one passenger call pushbutton with an integral lamp in each
lavatory. Each DEU A interfaces up to three passenger call pushbuttons and lights. Each pushbutton and light is separately addressable. The CAM data assigns each pushbutton and light to a LH or RH cabin zone. First activation of a passenger or lavatory pushbutton activates a chime. Visual indications come on. A second activation of a passenger or lavatory pushbutton reset the visual indications.
(3) Operation of the Passenger Call System
(a)
Energization Energization of the passenger call system is as for CIDS energization . On energization of the CIDS, the passenger call function of the CIDS becomes fully operational. The cabin is divided up into forward and aft zones according to the CAM data. All seat row numbering lights are switched on for boarding purposes.
