PURPOSE:To prevent the sound of alarm from being drowned by noise by automatically shifting to an audio alarming system when the failure of each part of running equipment is detected in a passenger truck provided with audio equipment such as radio. CONSTITUTION:When the main switch 15 is closed, speakers 7 and 7a broadcast stereo music. When an emergency such as lack of fuel occurs, the signal of a detector operates an audio alarm unit 11 and selects a switchover system 9. The speakers 7 and 7a are disconnected from a sound generation system 8 and connected to an alarm system 11. Only an alarm sound is broadcasted responding to shortage of fuel by the direction of computer. Therefore, the operator can hear the generation of failure and take a prompt and proper step. |
