Setup & Installation
1. Battery Installation
The XC01-M comes with a pre-installed CR123A Lithium Metal battery. To activate the device, remove the insulating pull tab from the battery compartment. The device will emit a short beep and the LCD display will light up, indicating it is powered on and ready for setup.
2. Placement Options
The XC01-M offers versatile placement. It can be used as a freestanding unit on a flat surface or wall-mounted using the provided screws and anchor plugs. For optimal CO detection, place the detector in areas where CO is likely to accumulate, such as near fuel-burning appliances or in sleeping areas.

The X-Sense Smart Carbon Monoxide Detector XC01-M offers flexible placement options. It can be used as a freestanding unit on a flat surface, such as a countertop, or securely mounted to a wall using the provided hardware. Its compact design allows for discreet placement in various home environments.
3. App Connection (Requires X-Sense SBS50 Base Station)

The X-Sense Home Security App provides real-time notifications for triggered alarms, such as a smoke alarm detected in the living room. The app interface displays connected devices, their locations, and options to locate or silence alarms, offering remote monitoring and control.
Operation
1. Status Indicators
- Green LED: Indicates normal operation and power.
- Yellow LED: Indicates a fault or low battery.
- Red LED: Indicates a CO alarm.
2. CO Alarm Levels & Response Times
The XC01-M is programmed to sound an alarm at the following CO concentrations within the specified timeframes:
- 70 PPM: Alarm within 60-240 minutes.
- 150 PPM: Alarm within 10-50 minutes.
- 400 PPM: Alarm within 4-15 minutes.
Note: As CO concentration increases, the alarm will activate faster. If an alarm is triggered, move to fresh air immediately and call 911.

The LCD display on the XC01-M detector shows the current CO level in parts per million (PPM). It also features a 'Peak CO' concentration memory, allowing users to view the highest CO level detected since the last reset or power cycle. This provides valuable information for monitoring potential CO hazards.
3. Remote Monitoring & Device Sharing
Through the X-Sense Home Security App, you can monitor CO levels from anywhere, receive real-time push notifications for alarms, low battery, and fault conditions. The app also allows you to share access to your home safety devices with family members, enabling them to check history, receive notifications, and silence devices.

The X-Sense Home Security App enables remote monitoring of the XC01-M Carbon Monoxide Detector. Users can check CO levels, receive alerts, and manage device settings from anywhere, allowing family members to stay informed about home safety.
Maintenance
1. Battery Replacement
The XC01-M uses a CR123A Lithium Metal battery. When the yellow LED flashes and the device beeps, it indicates a low battery. Replace the battery promptly to ensure continuous protection.
2. Regular Testing
Test the detector weekly by pressing the test/silence button on the device or through the X-Sense Home Security App. This verifies the unit's electronics and alarm functionality.
Troubleshooting
- Yellow LED Flashing: Indicates a fault or low battery. Check the app for details or replace the battery.
- Red LED Flashing & Alarm Sounding: High CO levels detected. Immediately move to fresh air and call 911.
- No Display/No Power: Ensure the battery is correctly installed and fully charged. Replace if necessary.
