Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your First Alert CO615 Dual-Power Carbon Monoxide (CO) Detector. This device is designed to alert you to the presence of carbon monoxide gas, a colorless, odorless, and tasteless gas that can be deadly. The CO615 features a dual-power system with a plug-in design and battery backup, ensuring continuous monitoring even during power outages, and a digital display for clear CO level readings.
Please read this manual thoroughly before using the detector and retain it for future reference. Your safety is paramount.
What's in the Box: One First Alert CO615 Carbon Monoxide Alarm, two AA batteries, and this user manual.

1. Setup and Installation
Proper placement and installation are crucial for the effective operation of your carbon monoxide detector.
1.1 Unpacking and Battery Installation
Carefully remove the CO detector from its packaging. Locate the battery compartment on the back of the unit. Install the two included AA batteries, ensuring correct polarity. The batteries provide backup power in case of an AC power interruption.

1.2 Placement Guidelines
For optimal protection, install at least one CO detector on each level of your home, including the basement, and in or near each sleeping area. Carbon monoxide is slightly lighter than air and mixes with warm air, so it is recommended to install the detector at least waist height. Avoid placing the detector:
- Directly above or next to fuel-burning appliances.
- In direct sunlight or near heat sources.
- In areas with high humidity, such as bathrooms.
- In areas with excessive dust, dirt, or grease.
- Within 5 feet (1.5 meters) of cooking appliances.
- In garages, as exhaust fumes can cause nuisance alarms.

1.3 Powering the Unit
Plug the CO615 detector into a standard 120V AC wall outlet. Ensure the outlet has continuous power. The unit will briefly light up its digital display to indicate it is receiving power. The installed batteries will serve as backup power if the AC power supply is interrupted.

1.4 Initial Test
After plugging in the unit and installing batteries, press and hold the "Test/Silence" button to ensure the alarm is functioning correctly. The alarm will sound a loud 85-decibel horn, and the digital display will activate. Release the button to silence the alarm.
2. Operating Instructions
Your First Alert CO615 detector continuously monitors for carbon monoxide and provides clear indications of its status.
2.1 Digital Display
The backlit digital LED display provides a clear readout of current carbon monoxide concentrations in parts per million (PPM). Under normal conditions (no CO detected), the display will typically show "0" or remain blank to conserve power, with a small green LED indicating normal operation. If CO is detected, the display will show the CO level.

2.2 Test/Silence Button
The "Test/Silence" button serves two functions:
- Test: Press and hold the button to test the unit's alarm and display functionality.
- Silence: Press the button briefly to silence a non-threatening alarm or a low battery warning for a short period. The alarm will reactivate if the CO levels persist or the low battery condition continues.
2.3 Peak Level Feature
The detector features a peak level memory. Press the "Peak Level" button to view the highest concentration of carbon monoxide measured since the last reset or power cycle. This can be useful for monitoring potential intermittent CO issues.
2.4 Alarm Indication
When carbon monoxide levels reach dangerous thresholds, the unit will sound a loud 85-decibel alarm. The digital display will show the CO concentration, and an "EVACUATE" message may appear. If the alarm sounds, immediately move to fresh air and call emergency services.
3. Maintenance
Regular maintenance ensures the continued reliability of your CO detector.
3.1 Regular Testing
Test your CO detector weekly by pressing and holding the "Test/Silence" button until the alarm sounds. This confirms the electronic circuitry, horn, and battery are working.

3.2 Battery Replacement
The unit will emit an audible and visual low battery signal (a chirp and a low battery indicator on the display) when the AA backup batteries need replacement. Replace both batteries immediately with new AA alkaline batteries. An indicator will also alert you if a battery has been removed.

3.3 Cleaning the Detector
Clean the exterior of your CO detector regularly to prevent dust and debris buildup. Use a soft, damp cloth to wipe the surface. Do not use cleaning sprays, solvents, or polishes, as these can damage the unit or interfere with sensor operation. Do not paint the unit.
3.4 End-of-Life Warning
The CO615 detector has a 7-year operational life. After approximately 7 years from the date of manufacture, the unit will emit an end-of-life signal (three chirps) to indicate it needs to be replaced. This is a critical safety feature, as CO sensors degrade over time. Replace the unit immediately when this signal occurs.

4. Troubleshooting
Refer to this section for common issues and their resolutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm sounds continuously or intermittently. | Carbon monoxide detected. | Immediately move to fresh air. Call emergency services (Fire Department) and do not re-enter the premises until cleared by professionals. |
| Unit chirps periodically (e.g., once a minute). | Low battery warning. | Replace both AA backup batteries with new ones. Ensure correct polarity. |
| Unit chirps three times repeatedly. | End-of-life warning. | The detector has reached the end of its operational life (approximately 7 years). Replace the entire unit immediately. |
| Digital display is blank or unit appears off. | No AC power; Batteries drained or missing. | Check if the outlet has power. Ensure AA batteries are correctly installed and not drained. If AC power is out, the unit will run on battery backup. |
| Alarm sounds during testing but not otherwise. | Normal operation. | The unit is functioning correctly. It will only alarm when dangerous CO levels are detected. |
