a one pink indicator light,

a one green indicator light. The microcomputer coordinates the operation of all the AIP modules and running of the software contained in the ROM. 14 to 32 V DC powers the AIP with a voltage regulator which derives the necessary internally used voltages. The line receiver/serial interface is for RS232 reception. One output is provided and is used to signal the BITE status of the AIP (see the BITE description in the 'Operation' section (Ref. paragraph 6.F.(2)(f). All messages for alphanumeric display are stored in the EPROM. They are selected and transferred to the display according to commands received from the RS232 interface. The parallel interface connects to the two lamps. These can be switched on in either continuous or flashing mode (1Hz) according to the commands received.

G. Area Call Panel
(Ref. Fig. 035)
(1) Description
(a) General The Area Call Panel (ACP) 340RH is installed at each end of the passenger compartment to the left and right of center in the ceiling. The ACP has four separately controlled fields, each contains two parallel connected lamps. The lights are visible from the front or rear of the ACP. They are colored in one of two available cover lenses. The colors are as follows:
-
color 1 = amber,
-
color 2 = pink,
-
color 3 = pink,
-
color 4 = blue.
The fields are activated either continuously or are flashed. They
are used as a far-call facility to warn cabin attendants of
PAX-call, interphone call, and lavatory smoke.

(1) Description
(a) General The Area Call Panel (ACP) 340RH is installed at each end of the passenger compartment to the left and right of center in the ceiling. The ACP has four separately controlled fields. Each contains parallel connected colored LEDs. The ACP is covered by a milk-colored cover. The illuminated lights are visible from the front or rear of the ACP. The colors are as follows:
-
color 1 = amber,
-
color 2 = pink,
-
color 3 = pink,
-
color 4 = blue.
The fields are activated either continuously or flashing. They
are used as a far-call facility to inform cabin attendants of
PAX-call, interphone call and lavatory smoke.

(2) Operation
(a) General Five discrete connections connect each ACP to a DEU B. One for each field and one for a common connection. The DEU B switches the fields separatly. Any field or combinations of fields can be OFF, steady ON or flashing ON. For flashing the DEU B repeatedly switches the field(s) on and off.

Call Functions The ACP performs call functions which are described fully under the appropriate 'System Operation' section of this chapter (Ref. paragraph 7.). For lavatory smoke, the respective chapter must be refered to.
