4. Installation
Proper installation ensures optimal performance and detection. Choose a location that receives ample sunlight for the solar panel and provides a clear line of sight for the motion sensor.
4.1 Mounting Guidelines
- Mount the alarm in a position where the solar panel is exposed to direct sunlight for most of the day.
- Ensure the detection area is clear of obstructions that might block the sensor or cause false alarms (e.g., swaying branches).
- Use the provided mounting bracket and hardware to securely attach the device to a wall, fence post, or other stable surface.
4.2 Recommended Installation Height and Detection Range
The effective detection range varies with installation height and environmental conditions. Refer to the diagrams below for guidance:

Figure 4: Installation height recommendations and corresponding detection distances for the alarm.
- Installation Height 2.2m: Vertical detection distance up to 8m (daytime), up to 10m (maximum). Detection distance at night: 9-12m.
- Installation Height 2.0m: Vertical detection distance up to 6m (daytime), up to 9m (maximum). Detection distance at night: 9-12m.
- Installation Height 1.8m: Vertical detection distance up to 5m (daytime), up to 10m (maximum). Detection distance at night: 9-12m.

5. Charging
The XUK Solar Motion Sensor Alarm is primarily powered by its integrated solar panel. For initial setup or in prolonged periods of low sunlight, the device can be charged via its USB power interface.
5.1 Solar Charging
Ensure the solar panel is clean and unobstructed to maximize charging efficiency. A 45° tilt angle for the solar panel is recommended for optimal sunlight absorption.
5.2 USB Charging
Connect a standard USB charger (not included) to the USB power interface on the device. The indicator light will show charging status. The internal battery provides up to 100 hours of standby time on a full charge.

6. Operating Modes
The alarm offers four distinct operating modes, selectable via the 'Working Mode Switching' button:
- Mode A: 24-Hour Sound and Light Monitoring. The alarm will activate with both sound and flashing lights upon detecting motion, day or night.
- Mode B: Night Sound and Light Monitoring. The alarm will activate with both sound and flashing lights upon detecting motion only during nighttime hours.
- Mode C: Night Flash Only Monitoring. The alarm will activate with flashing lights only upon detecting motion during nighttime hours. No sound is emitted in this mode.
- Mode D: Monitoring Disabled. The alarm is inactive and will not detect motion or trigger alerts.

7. Motion Detection
The integrated infrared sensor detects movement within a specified range and angle. When motion is detected, the alarm triggers its deterrent functions.
- Detection Angle: 110 degrees horizontally.
- Detection Distance: 8-12 meters (approximately 30-40 feet).
