To find out how old your Kidde carbon monoxide alarm is, check the back or side of the unit for a stamped manufacturing date label.
The manufacture date code is stamped on the label located on the back of the alarm.
Most Kidde carbon monoxide detectors have a lifespan of 7 to 10 years from the date of activation or manufacture, depending on the model. Sensors degrade over time, so when the alarm reaches its limit, the entire unit must be replaced.
Carbon monoxide (CO) detectors typically last 5 to 10 years depending on the manufacturer. To determine if yours has expired:
Protect Your Home and Family with Carbon Monoxide Alarms
Replace carbon monoxide alarms every 5 to 7 years, depending on the make and model. Newer CO alarms have a 10-year sealed battery that does not need changing. At 10 years, the entire device is replaced.
Carbon monoxide (CO) detectors generally need to be replaced every 5 to 7 years. Because the internal sensors degrade over time, you cannot rely on an old unit to keep your home safe.
Each smoke detector should be replaced 10 years after the date of installation. If you're not sure when it was installed, check the back of the smoke detector for the manufacture date and add 10 years to it to get the expiration or replacement date.
Carbon Monoxide detectors don't last forever. Over time their effectiveness decreases, and most will need to be replaced every 7 to 10 years, depending on the manufacturer. All detectors that were produced after August 1, 2009, have an end-of-life warning that indicates when it's time to replace the unit.
Carbon monoxide (CO) gas mixes evenly with air, so detectors are highly effective whether placed high on the ceiling or low on the wall. Experts generally recommend mounting them about 5 feet above the floor (eye level) or just a few inches below the ceiling.
Yes. A green light is completely normal and means your carbon monoxide (CO) detector has power and is actively monitoring your home. It is very common for this green light to blink once every 30 to 60 seconds to save battery life.
Here are some signs that your alarm may need to be replaced:
Fire services, like the International Association of Fire Chiefs (IAFC) and the NFPA, recommend installing a carbon monoxide (CO) alarm on every floor of your home, including the basement, and within 10 feet of every bedroom door. You should choose any CO alarm that bears the mark of a recognized testing laboratory (such as UL).
All smoke alarms (including hard-wired or those with removable batteries) should be replaced after 10 years, or by the replace by date on the base or earlier if they are found to be defective. The sensor in a smoke alarm can degrade over time.
If you look at the back of the alarm, you will see the name of the product and the model number in bold text below the logo.
BRK Brands, Inc. A proposed class action lawsuit claims that smoke alarm manufacturers Kidde Safety Equipment and First Alert have failed to warn consumers that their ionization-only smoke detectors are technologically incapable of detecting slow-moving, smoldering fires in real-world settings.
A Kidde alarm may keep chirping after a battery change due to residual power holding an error code, poor battery contacts, or the unit reaching its end-of-life.
Avoid placing next to or over a fireplace or stove. Install them away from the kitchen, bathroom, sunny spots, or open windows since humidity could interfere with the sensors. If you require a CO alarm for a new residence, the detector should be interconnected so that when one goes off, they all go off.
Carbon monoxide (CO) is measured in parts per million (ppm). Any level consistently above 9 ppm is considered concerning indoors, as it exceeds the EPA's maximum safe ambient level for an 8-hour period.
A pattern of 5 beeps every 30 seconds usually indicates that your carbon monoxide (CO) detector has reached its "End-of-Life". This means the internal sensor has expired and the unit can no longer safely detect CO gas.
Carbon monoxide (CO) detectors typically last 5 to 10 years depending on the manufacturer. To determine if yours has expired:
It is also a good idea to know the signs of a potential CO problem:
Kidde carbon monoxide (CO) detectors must be replaced every 7 to 10 years, depending on your specific model. The exact lifespan can be found on the manufacturer's label on the back of the unit. The entire device must be replaced, not just the battery.
Kidde smoke detectors last 10 years from their date of manufacture. If your device is a combination smoke and carbon monoxide (CO) detector, it should be replaced every 7 to 10 years depending on the exact model.
Hardwired smoke detectors are connected to your home's electrical system, and improper installation or handling of electrical connections can be dangerous. An electrician has the expertise to disconnect the old smoke detectors, install the new ones, and test them to ensure everything is working correctly.
For hardwired units, a steady green LED light indicates that the alarm is receiving AC power. Battery-operated units will have a quick flash every 30-45 seconds. However, this does not necessarily mean the alarm is working. Pressing the Test button is the only recommended method to ensure functionality.
