What color should the smoke detector light be?
Summary of the article: Should smoke detectors blink red or green
In some models of smoke detectors, a red or green LED light flashes periodically without an alarm sounding to show that it is receiving power and is operating normally.
Hardwired smoke detectors will have a steady green LED light to show that it’s receiving AC power, while battery-operated units will have a quick flash every 30-45 seconds.
If the green light on the smoke detector is blinking red, it could mean that the batteries in the unit are low and need to be replaced. It could also indicate that the smoke detector needs to be replaced as they don’t last forever.
Once smoke is no longer in the air, the alarm should become silent and blink red indicating it is in a desensitized state. You can push the test/silence button to make the light stop blinking.
If the green light on the smoke detector is off, it could mean that the AC power has been interrupted. Check the circuit breaker and AC wiring to correct the problem.
If the smoke detector has a blinking or steady light with no audible alarm sound, it typically indicates that the unit is receiving power.
A flashing green light on a smoke detector is used to indicate which alarm first detected the fire in a system with multiple alarms on the same powerline.
Typically, a smoke alarm has a red and green light to show that the system is working properly. Some models may have an additional light indicator for specific malfunctions or battery replacements.
The green light on a smoke alarm will blink every 5 seconds when in “battery only” mode and solid green when it detects a smoke or CO hazard. It will flash every 2 seconds in “hush” mode.
Sometimes the red light on a smoke detector means nothing is wrong. It is just an indicator that the system is working properly.
To check if a smoke detector is off, press and hold the test button. A loud siren should sound. If it doesn’t, replace the batteries.

The LED will flash along with the alarm sound. There are different occasions where your smoke detector can start flashing.
Why did my fire alarm randomly go off in the middle of the night

Why is my smoke alarm beeping no green light
It's Time To Change the Battery
Low batteries are the most common reason smoke detectors beep or send a trouble signal to your security panel when there is no smoke or fire. As the battery weakens, the device will beep regularly to let you know it's time to replace it.
What does a solid red light on a smoke detector mean
Generally the solid red light indicates that is the particular smoke detector that tripped. The detectors need to be reset. Typical 110 volt household smoke detectors reset when the smoke clears. Most alarm system smoke detectors need to be reset from the control panel.

Do smoke detectors go off for carbon monoxide
Most of the time, when one of these detectors sounds an alarm, the other one won't go off as well. That's because you'll often have smoke present with no carbon monoxide present, or vice versa. However, the alarms in both types of detector could sound at the same time for some fires.
Why did my smoke alarm go off in the middle of the night for no reason
This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. Most homes are the coolest between 2 a.m. and 6 a.m. That's why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
