Installation
Mounting
•Remove the mounting plate from the back of the alarm by holding the mounting plate and twisting the alarm in the direction indicated by the “OFF” arrow on the alarm cover.
•After selecting the proper location for your CO Alarm, as described on page 4 and wiring the A.C. Quick- Connector harness as described in Wiring, attach the mounting plate to the electrical box. To ensure aesthetic alignment of the alarm with the hallway, or wall, the “A” line on the mounting plate must be parallel with the hallway when ceiling mounted or horizontal when wall mounted.
•Pull the A.C. Quick-Connector through the center hole in the mounting plate and secure the bracket, making sure that the mounting screws are positioned in the small ends of the keyholes before tightening.
•Plug the A.C. Quick-Connector into the back of the alarm (see Figure 2), making sure that the locks on the connector snap into the unit. Push the excess wire back into the electrical box through the hole in the center of the mounting plate.
FIGURE 2 ATTACHING THE A.C. QUICK-CONNECTOR
•Install the alarm on the mounting plate and twist the alarm in the direction of the “ON” arrow on the cover until the alarm ratchets into place (this ratcheting function allows for aesthetic alignment). Note: The alarm will mount to the bracket in 4 positions (every 90 degrees).
Installation
•Turn on the A.C. power. The green A.C. Power On Indicator should be lit when the alarm is operating from A.C. power.
•For alarms equipped with 9V battery back-up: Pull the Battery Pull Tab (yellow tab protruding from unit) completely out of unit. This will automatically connect the battery.
Tamper Resist Feature
To make this CO alarm somewhat tamper resistant, a tamper resist feature has been provided. Activate the feature by breaking off the four posts in the square holes in the mount-ing plate (see Figure 3A). When the posts are broken off, the tamper resist tab on the base is allowed to engage the mount-ing plate. Rotate the alarm onto the mounting plate until you hear the tamper resist tab snap into place, locking the alarm.
Using the tamper resist feature will deter children and others from removing the alarm. To remove the alarm, press on the tamper resist tab, and rotate the alarm off of the mounting plate (see Figure 3B).

Operation
Seven (7) years after initial power up, this unit will “chirp” every 30 seconds to indicate that it is time to replace the alarm. After seven years the device may no longer detect carbon monoxide accurately and should be replaced immediately. To help identify the date to replace the unit, a label has been affixed to the side of the alarm. Write the “Replace by” date (7 years from power up) in permanent marker on the label.
Your new Kidde carbon monoxide alarm is a sophisticated electronic device – yet very simple to understand. The green “Power” LED will illuminate to identify the unit is monitoring for carbon monoxide. If it senses dangerous levels of carbon monoxide, the red “Alarm” LED will flash accompanied with an audible alarm pattern. (See page 12 for description of alarm patterns).
However, if interconnected to other Kidde alarms, or if the backup battery is low or missing, or if the unit malfunctions, it will display other readings (and alarm differently) to alert you of specific conditions. Please familiarize yourself, and other family members, to the difference between a CO alarm and an alarm signifying a problem with the unit itself.
The table on Page 12 illustrates what the audible alarm patterns are, and what the recommended actions are.
Operation
Carbon Monoxide (CO) Alarm Indicator
When the CO alarm senses a dangerous level of CO, the unit will emit a loud alarm beeping pattern. The alarm pattern is 4 short beeps followed by 5 seconds of silence. This cycle repeats as long as a dangerous CO conditions exist. The red LED (Alarm) will flash the same pattern.
If this unit is interconnected with other Kidde CO alarms, the amber LED (Initiating Alarm) of the unit which first detected the CO, will light and remain on until reset. The other interconnected CO alarms will also alarm to warn you that CO was detected.
WARNING: For alarms equipped with 9V battery back-up: When powered by battery backup only, after four minutes, the alarm will sound and flash only once every minute, to conserve battery life.
Fire Alarm Indicator
When an interconnected Kidde smoke alarm detects smoke, this CO alarm unit will sound a smoke/fire alarm pattern of continuous beeps for four (4) seconds, followed by 1 second of silence. This cycle repeats as long as smoke signal persists to alert you of the condition. If this happens, leave the premises immediately by your escape plan and call your local fire department.
WARNING: This unit is not a smoke alarm and will not detect smoke or fire. It will only alarm for smoke/fire if it receives a signal from an interconnected Kidde smoke alarm.
Note: A smoke/fire alarm will override a CO alarm condition.

WARNING: If at any time you test the alarm and it does not perform as described, have it replaced immediately.
NOTE: Reference to battery back-up operation is only applicable to units that are equipped with battery back-up option.
Testing
To test the alarm, press the Test/Reset button. If the unit is operating properly, you should hear 4 quick beeps – followed by 5 seconds of silence – followed by 4 quick beeps. The red LED will flash along with the beeps and the amber LED will illuminate. Within several seconds the unit will return to monitor for carbon monoxide.
If interconnected to Kidde smoke alarms, pressing the Test/Reset button on the CO alarm will have no effect on the smoke alarms. The smoke alarms will not be tested and will not alarm. However, when pressing the Test button on an interconnected smoke alarm, the CO alarm will emit a Smoke/Fire audible and visual alarm pattern of continuous beeps for four (4) seconds, followed by 1 second of silence, repeated.
Note: You do not need to press the Test button to take a CO reading.
Battery Replacement
For alarms equipped with a 9V battery back-up, the 9 volt battery is to supply short-term backup during a power outage.
When replacing the battery, use one of the following approved brands:
Duracell | MN1604 or MX1604 |
Energizer | 522 |
Gold Peak 1604A
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.
The 9 volt battery is not rechargeable. If the 9 volt battery is missing, disconnected, or if the battery’s power is low, a red LED flash will occur once every 15 seconds, accompanied by an audible beep. If this happens, the battery must be replaced.
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.
