Does the smoke alarm on the high-speed rail smoke a cigarette and call the police?
The smoke alarms on high-speed rail are mainly used to detect the nature of fire, not smoke control. The sensitivity of alarms is different. The smoke concentration of a cigarette is not enough to alarm the alarm, the smoke concentration is not enough, and the ventilation system is easy to dilute.
Smoke detector basically detects smoke, will call the police, the train slows down or even stops.
Smoke alarms on the high-speed rail don't call the police when they smoke a cigarette.
If it's far from the smoke alarm, you probably won't call the police
