WARNING: After ten (10) years from initial power up, this alarm will “beep” two times every 30 seconds to indicate that it is time to replace the alarm. Replace the alarm immediately! It will not detect CO in this condition.
End of Life Notification
End of Life “Hush”: This model has an End of Life Hush feature which allows you to press the test/reset button on the alarm and disable the “chirps” for a period of 3 days. This gives you a chance to replace the alarm at a more convenient time while still providing protection. The two chirps will repeat again every 3 days and can be reset a total of 30 days. After 30 days, the End of Life signal cannot be “Hushed.” The alarm must be replaced.
During this End of Life HUSH period, your alarm is monitoring for CO.
To help identify the date to replace the alarm, a label has been affixed to the side of the alarm. Write the “replace by” date (ten years from power up) in a permanent marker on this label. Model KN-COB-LP2 !

CO alarms should be mounted in or near bedrooms and living areas. It is recommended that you install a Kidde CO alarm on each level of your home.
When choosing your installation locations, make sure you can hear the alarm from all sleeping areas. If you install only one CO alarm in your home, install it near bedrooms, not in the basement or furnace room.
IMPORTANT: Improper location can affect the sensitive electronic components in this alarm. To avoid causing damage to the unit, to provide optimum performance, and to prevent unnecessary nuisance alarms:
To install or replace the batteries in this Kidde CO alarm, please perform the following steps.
When replacing the batteries, use one of the following approved Alkaline brands:
These batteries can be purchased where you bought the alarm or at a local hardware store. Use of a different battery may have a detrimental effect on the alarm operation.
NOTE: Do not use LIthium batteries in this unit.
IMPORTANT: Constant exposures to high or low humidity may reduce battery life. A good safety measure is to replace the battery at least once a year, or at the same time as you change your clocks for daylight saving time.
After installing or changing the batteries, reinstall your alarm. Test your alarm by using the Test/Reset button and check that the green LED flashes once approximately every 60 seconds.
When the batteries need to be replaced, the unit will produce a low battery warning. The Low Battery HUSH® feature allows you to press the button on the alarm and disable the “chirp” for a random period of up to 12 hours. This gives you a chance to replace the battery at a more convenient time by disconnecting the alarm from power. During this Low Battery HUSH® period, your alarm is monitoring for CO.
This CO alarm can be either wall mounted or placed on a tabletop.
For wall mounting, follow these steps:
1. Remove back mounting plate from the alarm, place it in the desired location, and mark the location of the two holes needed on the wall
2. Insert the two screws provided until the screw heads are protruding approximately 1/8” from the wall. (If mounting in a plasterboard or drywall, drill a 3/16” hole in the wall and use the plastic anchors provided.)
3. Hook the CO alarm over the screws and onto the keyholes in the back mounting plate of the alarm. After the mounting plate is secured to the wall, slide the alarm down over the mounting plate until it snaps into place.
Your CO alarm may also be placed on a tabletop. If the alarm is not wall mounted, be sure it is no more than three feet from the floor. The alarm does not have to be within three feet from the floor to detect CO, but at this height it is less likely to sustain damage from a fall.
Two labels have been provided that have important information on what to do in case of an alarm. Add the phone number of your emergency service provider in the space provided. Place one label next to the alarm after it is mounted, and one label near a fresh air source such as a door or window.
Whenever the alarm is operating, the green Power LED flashes every 60 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.
| Function | LED Display | Alarm Sound | Unit Status | Recommendation |
| Normal Operation | Green LED flashes every 60 seconds | None | Normal DC operation (sensing no CO) and with good batteries | None |
| Carbon monoxide alarm | Red LED flashes with beeps. | 4 quick beeps, 5 seconds silence, repeating | Alarm condition. Dangerous concentrations of CO detected | Refer to “What to do When the Alarm Sounds” (inside front cover) |
| Low battery | Red LED flashes every 60 seconds | One quick beep every 60 seconds | Batteries need to be replaced | Replace all AA batteries |
| Error / service alarm | Red LED flashes every 30 seconds | One quick beep every 30 seconds | Unit is in error condition | Replace batteries . If condition continues, unit has malfunctioned. Replace immediately. Unit will not respond to CO |
| Error | Red LED constantly on | Constant alarm | Very low battery or unit malfunction | |
| Normal Test/Reset function | Red LED flashes with beeps. | 4 quick beeps, 5 seconds silence, repeated once | Normal operation when Test/Reset button is pressed | CO not detected. Alarm for test purposes only |
| End of unit life indicator | Red LED flashes two times every 30 seconds | Two quick beeps every 30 seconds | End of unit life | Replace unit immediately. Unit will not respond to CO |
| Event Memory | Green LED flashes every 10 seconds | None | 100ppm or more CO previously detected | Push button to clear and test unit. |
When the alarm senses a dangerous level of CO, the unit will emit a loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5 seconds of silence, repeating for as long as dangerous conditions exist. The red Alarm LED will flash the same pattern.
If the unit has detected a CO concentration of 100ppm or greater, the Green LED will flash every 10 seconds. Pushing the test button will clear the Event Memory and initiate the test sequence.
NOTE: This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your fingers over the sounder opening while testing your alarm.
Caution: Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss.
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. The red LED will flash along with the beeps. Within several seconds the unit will return to monitor for CO.
Note: You do not need to press the Test button to take a CO reading.
To keep your alarm in good working order, you must follow these steps:
Move the CO Alarm to a remote location, to prevent possible damage or contamination of the sensor, prior to performing any of the following:
WARNING: Reinstall the CO Alarm as soon as possible to assure continuous protection.
The following is a list of substances that at high levels can damage the sensor or cause temporary readings that are not CO readings:
