If your System Sensor D4120 duct smoke detector is displaying a solid Amber LED, then this is the device's indication that the cover is either missing or not properly tightened down.
When your Smoke Detector chirps, do you see a yellow light? If you see a steady yellow while the Smoke Detector chirps, that means that its Tamper Switch isn't being held down all the way. In that case, try twisting the Smoke Detector clockwise until it locks into place.
Smoke detectors are equipped with little LED lights that display the unit's status. A green LED light indicates that the unit is functioning properly and receiving power in the majority of models. Often a yellow or orange indicator denotes some sort of error or malfunction in the system.
They are usually mounted in a high position located in the living room, hallway or bedrooms. You will notice two different lights on your smoke alarm: A steady green light shows the alarm is being powered. A red light that flashes once a minute shows the alarm is working.
If your smoke or heat alarm is flashing an amber LED, sometimes with a chirp, it may be due to your alarm being incorrectly attached to the baseplate. If correctly attached to the baseplate, your alarm should show a green LED flashing regularly, with a red LED flash every 45 seconds.
If the CO alarm gives a short beep and the Amber fault light flashes every 40 seconds it means that the self-checking circuitry may have detected a fault. Press and hold the Test/ Hush button until the horn sounds and it resets the unit. If the beeping starts again the alarm may be defective.
A smoke detector blinking red could mean:
It's Working Properly: Some brands use an occasional red blinking light to indicate the unit is working properly. Check with your manufacturer to make sure. Lingering Smoke After the Alarm: After a smoke alarm goes off, smoke might be lingering around the unit.
On First Alert carbon monoxide alarms, the red light flashes to show the CO alarm is properly receiving battery power. If you do not see the red light flashing, change the batteries in the alarm immediately.
The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and the red LED blinks every 10 seconds. This indicates that the alarm is in a temporarily desensitized condition.
If the panel is unable to set for any reason, the keyfob status LED flashes ORANGE indicating a fault is on the system. The fault will be shown on the keypad. The chime can be used for any input on the system.
A fire alarm supervisory signal is typically yellow and indicates there's an issue with another system that's attached and monitored by the fire alarm system.
The color code for all newly installed fire alarm system conductors shall be as follows: INITIATING DEVICE CIRCUIT shall be red and black. Red shall be positive and black shall be negative [IDC/SLC]. NOTIFICATION APPLIANCE CIRCUIT shall be blue and white.
Many smoke detectors use an LED light to show you that everything's working properly. If your device's on/off button has a stale red light, it likely means the system is working properly. Some detectors will even use a light that flashes periodically to tell you they're working.
If your smoke detector has turned a nice yellow or yellowish brown, it is well past time to replace the unit. The NFPA statistics on fire safety and operating smoke detectors are sobering. Three of every five home fire deaths resulted from fires in homes with no smoke alarms (38%) or no working smoke alarms (21%).

The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
The Smoke & CO Detector is not connected to its mounting bracket properly. In order to keep the Tamper Switch pressed, ensure the detector is mounted correctly on the bracket. Blinking yellow light. Chirps once a minute. Battery is low.
How to test your carbon monoxide detectors to ensure they are working properly? To test your carbon monoxide detectors, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds. Refer to the user manual for your specific model.
(3) If the CO Alarm gives a short beep and the amber fault light flashes every 40 seconds it means the self-checking circuit has detected a fault. Press and hold the test/hush button. If the amber light flashes without the horn sounding, the sensor is faulty.
A yellow light indicates a system fault has occurred and the meter is no longer able to provide protection. Blinks for at least 5 minutes to notify the user of fault. The unit can be restarted but may continue to shut off.
False or nuisance alarms are when your smoke detector or CO alarm goes off, but there is no presence of smoke or carbon monoxide in your home. However, if your smoke or carbon monoxide detector sounds indicating an emergency and you are not certain it is a nuisance alarm, evacuate the home and call 9-1-1.
Other models also have a yellow light which will be on if the battery is low or a sensor is starting to get plugged; the yellow light comes on prior to the chirping, which of course means the batteries need to be replaced.
Note: Do not unplug or move the CO alarm.
