WARNING CHIME SYSTEM : System Description

INFOID:0000000000892393

COMBINATION METER

• The buzzer (1) for the warning chime system is integrated in the

combination meter.

• The combination meter sounds the alarm buzzer installed in the

combination meter when receiving the buzzer output signal trans-
mitted from each unit. 

BCM

BCM receives signals from various units and transmits a buzzer output signal to the combination meter via
CAN communication if it judges that the warning buzzer should be activated.
