Is the indicator light of the smoke detector always on normally?

Most smoke indicators blink intermittently when they work normally, and the alarm is always on. If it stays on, it may be an alarm. If there is no fire and smoke comes in, smoking for a long time or running without cleaning, there will be too much dust inside. Just take it off, blow it and screw it on. If the alarm keeps on, there is something wrong with the probe. In addition, if the indicator light is on all the time, the host should have a fire alarm signal.
