2. Important Safety Information

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to alert you to the presence of CO, but it is not a substitute for proper maintenance of fuel-burning appliances or adequate ventilation. Always ensure proper installation and regular testing.

Potential Carbon Monoxide Sources

Common sources of carbon monoxide in the home include furnaces, portable fuel-fired generators, water heaters, fireplaces, portable fuel heaters, dryers, and stoves. Vehicles running in an attached garage can also produce dangerous levels of CO.

General Safety Guidelines

• Do not paint the detector. Paint can clog the sensor and interfere with its operation.
• Ensure proper ventilation in areas with fuel-burning appliances.
• Never ignore an alarm. Follow the procedures outlined in this manual immediately.
• This detector complies with UL 2034 Standards for carbon monoxide alarms.

3. Product Features

The Pumwry Carbon Monoxide Detector is equipped with several features to ensure reliable and user-friendly operation:

• Easy to Install: Comes with screws for easy installation on walls or ceilings.
• Battery Powered: Operates on 3 x 1.5V AA batteries (not included), ensuring constant monitoring even during power failures. Battery life is approximately 36 months.
• High Accuracy & Reliability: Features an advanced electrochemical carbon monoxide sensor for accurate real-time CO level detection.
• Instant Alert: A loud 85-decibel alarm and flashing red LED provide an early warning when CO levels reach dangerous thresholds.
• Self-test Function: Unit performs a self-test upon power-up, indicated by a “chirp” and red LED flash.
• Informative LCD: Displays real-time CO levels and remembers dangerous CO levels since the last preset. Also indicates malfunctions ('Err') and low battery ('Lb').
• Wide Application: Suitable for living rooms, kitchens, bedrooms, offices, hotels, dormitories, and portable use for travel.

4. Setup

4.1 Battery Installation

The detector requires 3 x 1.5V AA batteries (not included). To install the batteries:

1. Twist the back cover of the detector counter-clockwise to open the battery compartment.
2. Insert three AA batteries, ensuring correct polarity (+ and -).
3. Close the back cover by twisting it clockwise until it clicks securely into place.

4.2 Mounting

For optimal performance, install the detector on a wall or ceiling. Avoid corners or areas with limited airflow.

1. Choose a suitable location, typically in or near sleeping areas and on every level of your home.
2. Use the provided screws to secure the mounting bracket to the wall or ceiling.
3. Align the detector with the mounting bracket and twist clockwise to lock it into place.

5. Operating Instructions

5.1 Power On and Self-Test

Upon successful battery installation, the unit will sound a “chirp” and the red LED will flash once. The LCD will display “888” for a few seconds, then “000” for 3 seconds, indicating it has entered normal operation mode.

5.2 Understanding the LCD Display

The LCD provides real-time information about the CO levels and the detector's status:

• Real-time CO Levels: Displays the current carbon monoxide concentration in parts per million (PPM).
• '000' Display: Indicates the unit is in normal operation mode or during the self-test.
• 'Err' Display: Indicates the unit is malfunctioning. Refer to the Troubleshooting section.
• 'Lb' Display: Indicates low battery and requires replacement.

5.3 Alarm Sensitivity Settings (UL 2034 Compliant)

The detector is designed to alarm at specific CO concentrations and exposure times:

• 50 PPM: Alarms within 60-90 minutes.
• 100 PPM: Alarms within 10-40 minutes.
• 300 PPM: Alarms within 3 minutes.

5.4 Alarm Activation

When carbon monoxide levels rise to alarm thresholds, the detector will activate a loud 85-decibel alarm and the red LED will flash rapidly. If the alarm sounds, immediately move to fresh air and call emergency services.

6. Maintenance

6.1 Regular Testing

It is crucial to test your carbon monoxide detector regularly to ensure it is functioning correctly. Perform a test at least once a month.

To test the detector:

1. Press and hold the 'TEST/RESET' button on the front of the unit.
2. The unit will sound beeps and the red LED will flash, indicating a successful test.
3. Release the button to return to normal operation.

For a more comprehensive test, you can use a controlled source of CO:

1. Create test smoke by carefully burning a rolled-up newspaper (blow out the flames to let it smolder) or lighting a cigarette in an ashtray.
2. Hold the smoke source about 2 inches below your detector.
3. Watch the display - you'll see the numbers rise as it detects CO, and the screen will flash "CO" when gas is present.
4. You'll hear the 85dB alarm sound within 1-2 minutes if working correctly.
5. Clear the smoke and press the reset button when finished.

Important Testing Note: For accurate results, always use the newspaper or cigarette method described above. Avoid testing with car exhaust, gas stoves or grills, or other open flame sources, as these methods often don't produce enough concentrated CO to properly test your detector. The smoldering paper or cigarette gives the most reliable results while keeping you safe.

6.2 Battery Replacement

When the LCD displays 'Lb', it indicates that the batteries are low and need to be replaced. Replace all three AA batteries simultaneously with new ones to ensure continuous protection.

6.3 Cleaning

Clean your detector regularly to prevent dust and debris from interfering with its operation. Use a soft, damp cloth to wipe the exterior. Do not use cleaning solvents or spray directly onto the unit.
