Carbon Monoxide (CO) Alarm It will alarm when there are high levels of CO present, and when there are low levels of CO present over a longer period of time. When a CO condition matches either of these situations, the alarm/voice message warning system will sound, and be accompanied by the flashing red LED light.
Whenever the alarm is operating, the green Power LED flashes every 30 seconds to indicate the unit is monitoring for CO. If the alarm senses dangerous levels of CO, the red Alarm LED will flash and the alarm will emit an audible alarm pattern.
This is normal. The amber, green & red LED come on when you press the test button to show that they operate correctly. You should consult the user guide if the amber LED comes on at any other time.
If the red or green light on your CO detector is illuminated, that's a sign that the unit has power. If the light is off, replace the batteries and follow the reset steps.
On many carbon monoxide alarms, the red light flashes to show the CO alarm is properly receiving battery power. For these alarms, when you do not see the red light flashing, change the batteries in the alarm immediately.
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.
When the CO alarm emits a quick beep every 30 seconds and the red LED flashes, you may need to change the batteries. Replace the batteries in the alarm. If the alarm continues to emit a quick beep every 30 seconds and the red LED flashes, the alarm has reached the end-of-life.
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.
While pressing the Peak Level Memory button, press the Test/Reset button for two seconds and release both at the same time. The number on the display will turn to 0, the memory will be cleared and the carbon monoxide (CO) alarm will begin monitoring for CO.
The continuous digital display shows you the level of carbon monoxide (if any) the unit is sensing. The unit updates this reading every 15 seconds so you can watch levels rise or fall. unit reads “0” all the time. A reading of “0” is expected under normal conditions, and is good.
If the unit malfunctions, the red LED light will flash and the unit will chirp every 30 seconds indicating a system problem. If the red LED flashes every 60 seconds WITHOUT an audible chirp, this is the pre-warning that the battery will soon need replacing.
Kidde CO alarms have a proven life of seven to ten years, depending on the model type. Important Note! CO alarms do not detect the presence of CO when in end-of-life mode.
Green Light: The green LED will be lit continuously or flash every 30 seconds to indicate the unit is operating properly. In Hush® mode the LED blinks every 2 seconds and once per second if it is the initiating alarm.
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.
Carbon monoxide alarms alert you with four beeps. A single chirp means the battery is low or the detector should be replaced.
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.
Consult your User Guide for the exact procedure for your unit, but generally speaking, to test the alarm, press the Test/Reset button. If the unit is operating properly, you will hear 4 quick beeps – followed by 5 seconds of silence – followed by 4 quick beeps.
Note: Do not unplug or move the CO alarm.
If you're wondering how you can check that your carbon monoxide detector works, the answer is simple: testing. You should test your CO detector monthly to ensure your family's safety. The test button is the best way to test it because it will tell if the alarm is still sounding.
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.
Why does the red light flash on my carbon monoxide alarm? Do I have CO? 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.
1 beep every minute: This means that the alarm has low batteries and you should replace them. 3 beeps every minute: This means the alarm has encountered a malfunction and needs replacement. 5 beeps every minute: This means your alarm has reached the end of its life and needs to be replaced with a new alarm.
In most areas, the fire department does not charge to respond to carbon monoxide alarms or to check for the presence of CO in a residence. However, policies can vary depending on the jurisdiction or specific fire department. It's always a good idea to contact your local fire department for specifics on their policies.
