1. Introduction
The X-Sense XC0C-iR is a smart carbon monoxide (CO) detector designed to provide early warning of dangerous CO levels in your home or while traveling. Featuring a 10-year electrochemical sensor, an LCD digital display, and Wi-Fi connectivity for real-time alerts, this device offers reliable protection. Please read this manual thoroughly before installation and use to ensure proper operation and safety.
2. Important Safety Information
Carbon monoxide is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to alert you to the presence of carbon monoxide. It is not a substitute for proper maintenance of fuel-burning appliances, including ventilation and exhaust systems. Always ensure adequate ventilation in areas where fuel-burning appliances are used.
- Never ignore an alarm. Investigate the source of the CO.
- Do not paint the detector. Paint can clog the vents and interfere with sensor operation.
- Do not block the detector's vents. Ensure proper airflow for accurate detection.
- Test the detector regularly. Perform weekly tests to confirm functionality.

5. Setup and Installation
Follow these steps to set up your X-Sense XC0C-iR detector:
- Battery Installation: The detector comes with 2 AA batteries pre-installed. Ensure the plastic tab is removed to activate the batteries.
- Download the App: Download the "X-Sense Home Security" app from the App Store or Google Play.
- Create an Account: Open the app and follow the on-screen instructions to create an account.
- Add Device: In the app, select "Add Device" and choose the XC0C-iR. Follow the in-app instructions to connect the detector to your 2.4 GHz Wi-Fi network. Ensure your phone is connected to a 2.4 GHz network during pairing.
- Placement: Choose a suitable location. The detector can be placed on a flat surface or wall-mounted. For optimal detection, install it at breathing height (face height) and ensure it is not obstructed by furniture or curtains. Avoid placing it near vents, windows, or in direct sunlight.
- Wall Mounting (Optional):
- Use the provided drilling hole spacing label to mark the screw positions on the wall.
- Drill two holes and insert the anchor plugs.
- Secure the mounting bracket with the screws.
- Attach the detector to the mounting bracket by twisting it clockwise until it locks into place.
- Initial Test: After installation, press the "TEST/X" button on the detector or use the app to perform an initial test. The alarm should sound, and the LCD display should show a CO reading.
6. Operating Instructions
Understanding your detector's indicators and functions:
- LCD Display: Shows the current carbon monoxide concentration in parts per million (PPM). During normal operation, it typically displays "0 PPM".
- LED Indicator:
- Green: Normal operation.
- Blue: Pairing mode.
- Yellow: Fault or low battery.
- Red: CO alarm.
- Test/Mute Button: Press this button to test the alarm. During an alarm, press it to temporarily silence the alarm (mute function). The mute function is disabled if CO levels exceed 300 PPM.
