A. Prerecorded Announcement and Boarding Music Reproducer
(1) The Prerecorded Announcement and Boarding Music (PRAM) Reproducer 10RX is installed in the avionics compartment in a 4 MCU (ARINC 600) box. The pre-recorded announcements and the boarding-music are stored in flash memory cards. The PRAM has the capability to produce an emergency announcement in the event of rapid cabin decompression. The emergency announcement is stored in the PRAM. A ground signal from a rapid decompression sensor triggers the emergency announcement. All functions are remotely controlled from the audio module in the Fwd Attnd panel 120RH.
