# LEVEL 2 Messages:
# Amber warning, single chime

# LEVEL 1 Messages:
# Amber warning, no chime

# LEVEL 0 Messages: 
# No visual warning or chime: ECAM blue, green, or white message

# TYPES: Independent, Primary and Secondary, Status, and MEMO

# Operation: FWC receives electrical boolean or numeric signals, from the systems, and outputs a message, audible warning, or visual alert

# Electrical Connection: FWC1 is controlled by AC ESS, FWC2 by AC BUS 2

# Sounds: reduce volume by 6DB is engines are off

# ARINC 429: 100kb/s (high speed)

# PHASE: /FMGC/status/phase

# DISPLAY: 1 - EWD 2 - MEMO 3 - STATUS
