With all First Alert plug-in carbon monoxide alarms, any time there is a power outage, brownout, surge or other problem with the power, the alarm goes through a power up cycle. The flashing on your plug-in carbon monoxide alarm should stop after 5 minutes, then the light will stay a steady green.
In others, a steady or blinking green light on a carbon monoxide detector can mean it's detected a** low-level presence of carbon monoxide**. If the presence increased, it would cause the alarm to sound. It could also mean it's time to replace the battery, especially if it's also chirping.
How to test your carbon monoxide detector to ensure they are working properly? It is important to test your detectors monthly to ensure they are working properly. To test your CO alarms, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds.
LIMITATIONS OF CO ALARMS
(1) The CO Alarm will not work without good batteries - the green power light must flash every 45 seconds. If the battery has been drained the alarm will not give protection. Button test the alarm on return from holidays and other long absences.
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.
Signs of a carbon monoxide leak in your house or home
Sooty or brownish-yellow stains around the leaking appliance. Stale, stuffy, or smelly air, like the smell of something burning or overheating. Soot, smoke, fumes, or back-draft in the house from a chimney, fireplace, or other fuel burning equipment.
Purchase a CO testing kit at your local Lowes, Home Depot, or on Amazon.com. Use the included canister of CO to spray onto your carbon monoxide detector. Be patient. It sometimes takes up to 30 minutes from exposure to CO for the alarm to sound.
New tech in the house can sometimes take a little bit of time to get familiar with. Luckily, if your First Alert carbon monoxide alarm is holding a steady red light, this means that it is operating normally.
If the carbon monoxide concentration in the air is much higher, signs of poisoning may occur within 1-2 hours. A very high carbon monoxide concentration can even kill an exposed individual within 5 minutes.
There are three things that make carbon monoxide extremely dangerous: 1) The molecules of carbon monoxide are so small, they can easily travel through drywall; 2) Carbon monoxide doesn't sink or rise – it mixes easily with the air inside a home; 3) It is an odorless gas, so without an alarm to notify you that it is in ...
Clothes dryers. Water heaters. Furnaces or boilers. Fireplaces, both gas and wood burning.
The Carbon Monoxide Detection Systems Checklist mobile app inspects Carbon Monoxide Detection Systems using an iPad, iPhone, Android device, or a Windows desktop.
In domestic properties, your CO alarm can be triggered by any fuel burning appliance such as gas cookers, boilers and ovens. All of these appliances give off small traces of CO, but the levels can rise slightly when adequate ventilation isn't provided, or the venting is blocked or clogged by dust.
Self Checks/At-Home Testing
There isn't a self-diagnosis option for carbon monoxide poisoning, but anyone with confusion or a loss of consciousness should have 911 called for them.
Opening a window will slow carbon monoxide poisoning, but it likely won't stop it. There simply isn't enough airflow through most windows to get rid of the poisonous gas, and it could take between four and eight hours for the CO to dissipate entirely.
Most hard wired smoke alarms have batteries, so follow the same procedure as above. Hard wired smoke alarms typically have LED lights which help with the diagnostics. For models with green and red lights: green means it is working properly, red means it is not. Sometimes the green light will pulse.
Call 911 immediately and report that the alarm has gone off. Do not assume it is safe to reenter the home when the alarm stops. When you open windows and doors, it helps diminish the amount of carbon monoxide in the air, but the source may still be producing the gas.
Carbon monoxide alarms alert you with four beeps. A single chirp means the battery is low or the detector should be replaced.
Carbon monoxide detector batteries need to be replaced every six months (a great time to do this is during daylight saving time when you're turning your clocks back or forward).
