Will the smoke alarm in the hotel flash red?
The smoke alarm in the hotel will flash red. There is a light source inside the smoke alarm, usually a red LED light. When the alarm detects that the indoor smoke concentration reaches a certain value, the red LED light will flash quickly to remind people of the possible fire danger. This flashing mode can make people notice the alarm quickly and take corresponding measures. It should be noted that the smoke alarm will also perform self-checking under normal working conditions. At this time, the flashing of the light does not mean that there is really smoke, which is a normal phenomenon. Therefore, when the smoke alarm flashes red, it is necessary to judge whether it is a normal self-test or whether smoke is really detected.
