What is the normal light on a smoke detector?

The normal light on a smoke detector typically indicates its operational status. In most smoke detectors, this light is usually green or sometimes yellow. Here's what the normal light indicates:

1. Steady Green Light: A steady green light on a smoke detector usually indicates that the detector is receiving power and is in good working condition. It means that the smoke detector is operational and ready to detect smoke or fire.

2. Flashing Green Light: Some smoke detectors may have a flashing green light to indicate normal operation. Similar to the steady green light, this indicates that the detector is powered and functioning correctly.

3. Yellow Light: In some models, a yellow light might indicate low battery or a fault with the detector. If the light is yellow, it's essential to consult the smoke detector's manual to determine the specific issue and take appropriate action, such as replacing the battery or addressing any faults.

It's crucial to familiarize yourself with the specific indicator lights and their meanings for the smoke detector model you have installed in your home or building. Additionally, regularly testing smoke detectors and replacing batteries as needed ensures they remain in proper working condition to provide early warning in the event of a fire.
