Generally, a solid green light on your smoke detector means that it's working properly. If the green light goes off, you know that there's no power going to the system. As mentioned, a solid green light can also mean that your detector has finished its power upcycle.
In fire alarm system there are 3 universal colors to indicate the status of the devise or equipment. The green for normal, yellow for trouble and red for alarm condition. Most battery operated smoke sensors the green blinks for normal status and some steady green. If there is a problem the yellow will turn on.
Green and red LED lights that indicate normal operation and alarm status o Green Light: The green LED will flash every 30 seconds to indicate the unit is operating properly.
Typically, colored lights on your home alarm system often indicate similar messages such as: Solid or blinking green may indicate that your system is currently running without issue.
Your AC power may not be on. Hardwired units will have a power indicator light (red or green) that shines continuously when they are receiving electrical power. If you have a 10-Year model, the smoke alarm may not have been properly activated.
If it is working as it should, the smoke detector should beep several times once you've pressed the test button. If your smoke detectors don't beep when you test them or if the sound is muffled, you should consider replacing them. It could save your life.
If the Green power indicator light does not light, TURN OFF POWER TO THE JUNCTION BOX and recheck all connections. If all connections are correct and the Green power indicator still does not light when you restore the power, the unit should be replaced immediately.
Green - Alarm green is announced over the giant voice system or displayed with a green flag. It means that attack is not probable. This is a normal wartime condition. Operations may be resumed.
In most cases, a smoke detector beeping points to a low battery. Battery-operated smoke alarms, even the ones with a battery backup, need a constant source of power. When the power gets low, the detector beeps to tell you it's time to replace the batteries.
In addition, the requirements for visible fire alarms are required to meet the following standards: The flash rate must be between one and two flashes per second. The color must be either clear or white.
Why did my fire alarm randomly go off in the middle of the night? This is likely due to one of the common causes like low battery, dirt buildup, humidity, or insects interfering with the sensor. Test the alarm and clean it thoroughly to try and resolve the issue. Make sure batteries are fresh and secure.
Flashing green is normal. The green flashing is it responding to the main panel.

Red LED Indicator: The red LED will blink in conjunction with the alarm sound. Therefore, the red LED will blink during a smoke alarm, a low battery mode chirp, a unit error mode chirp or at end of unit life.
Hardwired units will have a steady green LED light to show that it's receiving AC power. Battery-operated units will have a quick flash every 30-45 seconds. This does not necessarily mean the alarm is working. Pressing the Test button is the only recommended method.
Recognisable usually by its green colour, the fire alarm call point is the enclosure that houses a button to activate a fire alarm. Usually, the user will break the glass and press the emergency button centred in the middle of the unit.
Green light signal means the driver can start the vehicle and move forward. Red light signifies that the vehicles should stop.
Check the green mains power light is on. If not, check fuse, circuit breakers and wiring connections. If the green light is off, the Lithium cells will deplete after some months without mains and will need to be recharged. If turning on the mains fails to stop the beeps, a fault may exist.
For hardwired smoke detectors, random beeping may result from electrical interference, loose connections, or power fluctuations. Wireless devices, such as Wi-Fi routers or baby monitors, can also disrupt the detector's signal, causing unexpected beeping.
Check that the light on the cover flashes. It should flash at least once every 60 seconds. Press and hold the 'test' button on the face of the smoke alarm until the alarm sounds, and then release it. The other alarms in your home should also sound as they are interconnected.
You may get a false alarm if the battery life is fading or if the detector isn't properly connected. To check the battery, remove the outer casing and check to ensure that the old battery is properly connected. If so, it's a good idea to replace the batteries.
A “chirping” sound means that it's time to change batteries. Because alarm sensors wear out, replace each alarm at least every 10 years. Also, alarms have labels showing when they were made. If you don't see a label, the alarm is old and must be replaced.
