3. Setup and Installation
Before installation, ensure you have read the full user guide included with your product. This section provides a general overview of the installation process.
3.1. Mark Installation Date
It is recommended to mark the current date on the alarm. This helps you track when the alarm was installed and when it needs to be replaced, typically 10 years from the installation date.

3.2. Mounting the Alarm
- Secure the mounting bracket to the ceiling or wall using the provided screws. Ensure the bracket is firmly attached.
- Align the alarm with the mounting bracket. The 10-year battery model will self-activate with a confirmation beep once securely attached.
- Twist the alarm clockwise onto the mounting bracket until it clicks securely into place.

This video demonstrates the steps for installing both hardwired and battery-operated Kidde alarms, including mounting the bracket and attaching the alarm. It also shows how to activate the battery for models with a pull tab, and mentions that 10-year battery models self-activate upon mounting.
3.3. Dust Cover (If Applicable)
If your alarm came with a proprietary dust cover (often red), ensure it is securely in place during construction or renovation to prevent false alarms from dust. The alarm will not operate until this dust cover is removed. Remove the dust cover at least 24 hours after construction is complete to allow for proper operation.
4. Operating Instructions
4.1. LED Indicators
The detector uses LED lights to indicate its current status:
- Green LED: Indicates normal operation. For 10-year battery models, it flashes every 60 seconds.
- Amber LED: Indicates a fault or error. It may blink with chirps every 60 seconds for a fault, or twice with 1 chirp every 60 seconds for a low battery (though this model has a sealed 10-year battery, end-of-life will be indicated differently).
- Red LED: Indicates smoke or carbon monoxide detection, accompanied by a loud 85-decibel alarm.

4.2. Testing the Alarm
Test your alarm weekly by pressing and releasing the central test/hush button. The alarm will sound a series of beeps to confirm proper operation. Due to the loud nature of the alarm, it is advisable to stand approximately 2.5 feet away or use ear protection during testing.

5. Maintenance
5.1. Cleaning
Clean your detector annually. Use a soft brush attachment on your vacuum cleaner to remove dust from the alarm's vents. Do not use cleaning solvents or sprays on the alarm.
5.2. End-of-Life Notification
This alarm is equipped with end-of-life notifications. After approximately 10 years of operation, the alarm will emit a series of chirps to indicate it's time for replacement. When this occurs, replace the entire unit promptly.
6. Troubleshooting
- Nuisance Alarms (False Alarms): The detector features enhanced sensing to reduce false alarms from cooking. If nuisance alarms persist, ensure the detector is not placed too close to cooking appliances or areas with high humidity. Refer to the placement guidelines in the user manual.
- Chirping Sound: If the alarm chirps, refer to the LED indicator section to determine the cause. For 10-year battery models, chirping typically indicates a fault or end-of-life.
- No Power/No Indication: Ensure the alarm is correctly twisted onto its mounting bracket to activate the internal battery. If the issue persists, the unit may be faulty and require replacement.
