Specifications

Setup & Installation

1. Powering the Devices

• Wireless Motion Sensor: The sensor has a built-in 3.7V 2000mAh rechargeable lithium battery. It can be charged automatically via its solar panel or manually via the DC-5V USB charging port.
• Wireless Receiver: The receiver can be powered by DC USB-5V or by inserting 3*AA batteries.

2. Wireless Motion Sensor Installation

Before permanent installation, identify the optimal angle and height for the sensor, then test its detection capabilities.

1. Placement: Choose a location where the sensor has a clear line of sight to the detection area.
2. Height:
   • For vehicle detection: Suggested height is 1-2 meters.
   • For human body detection: Suggested height is 2-4 meters.
3. Mounting Surface: Ensure the mounting surface is strong and does not vibrate.
4. Avoid Interference: Do not install the sensor near heat sources or under rotating objects, as these can cause false alarms.
5. Secure: Use the provided screws to securely mount the sensor via its screw mount base.

3. Adding Detectors (Pairing)

The wireless motion sensor and receiver are typically pre-paired and can be used directly. If you need to add new detectors or re-pair existing ones, follow these steps:

1. Enter Add State: Long press the [Set Key] on the receiver. The LED light will show red, indicating the host has entered the add state for Zone 1.
2. Select Zone: Short press the [Set Key] to cycle through the defense zones:
   • Zone 1: Red LED
   • Zone 2: Green LED
   • Zone 3: Blue LED
   • Zone 4: Purple LED
   Once you reach Zone 4, another short press of the [Set Key] will exit the add state.
3. Activate Detector: While the receiver is in the desired zone's add state, activate the motion detector (e.g., by triggering its motion sensor).
4. Confirmation:
   • If the host beeps twice and the LED flashes twice, the detector has been successfully added.
   • If the host beeps once and the LED flashes once, the detector was already added to another zone.
   • If the host beeps three times and the LED flashes three times, the memory for that zone is full.
5. Exit Add State: After successful addition, short press the [Set Key] until you cycle past Zone 4 to exit the add state, or wait 20 seconds for the host to automatically exit.

Operation

1. Power On/Off and Low Power Check (Receiver)

• Power On/Off: Long press the [Power Key] on the receiver.
• Check Low Power: Short press the [Power Key] to check if the detector has low power.

2. Adjustable Volume

The receiver offers 5 levels of volume adjustment, including a mute option. The maximum alarm sound can reach up to 110 dB.

• Use the [Volume Key] to cycle through the volume levels.

3. Multi-Zone Functionality

The receiver supports 4 distinct zones, each indicated by a different LED color (Red, Green, Blue, Purple). This allows you to assign specific detectors to different areas and easily identify where an alarm originated. Up to 2 detectors can be added to each zone.

4. Ringtone Selection and Cycle Times

The receiver has 16 fixed ringtones. You can set a specific ringtone for each zone to easily distinguish alarms.

1. Enter Ringtone Setting: Long press the [Set Key] until the LED shows red (add state). Short press [Set Key] to navigate to the desired zone.
2. Set Ringtone: Once in the desired zone's add state, short press the [Ringtone Key] to cycle through the 16 available tones.
3. Set Cycle Times: If needed, you can set how many times the selected tone will play (1-4 times optional). Short press the [Power Key] to set the cycle times. The LED light will flash X times to indicate the selected cycle.
4. Exit: Short press [Set Key] to cycle past Zone 4 or wait 20 seconds to exit the setting mode.

5. Doorbell Mode / Alarm Mode

The system can operate in different modes based on your needs:

• Doorbell Mode: When motion is detected, the receiver plays a selected doorbell tone.
• Alarm Mode: When motion is detected, the receiver triggers a loud alarm sound (up to 110 dB) and flashes its indicator light.

Maintenance

1. Cleaning the Sensor

If you need to clean the motion sensor, first disconnect its power source. Then, wipe it gently with a soft cloth moistened with a little alcohol. Avoid using harsh chemicals or abrasive materials.

2. Battery Management

• Motion Sensor Battery: The 3.7V 2000mAh rechargeable lithium battery is replaceable. Ensure to use a compatible replacement battery.
• Receiver Battery: If using AA batteries, replace them when the low battery indicator is active.
• Charging: Regularly check the solar panel on the motion sensor for obstructions to ensure efficient charging. Use the USB charging port for both devices if needed.

3. Weatherproofing

The motion sensor has an IPV44 weatherproof design, making it suitable for outdoor use. While it is resistant to splashes and rain, avoid submerging it in water or exposing it to extreme weather conditions for prolonged periods.

Troubleshooting

1. Low Battery Indication

• Host (Receiver): When the host battery is low, its LED will flash 4 times every 60 seconds. Replace the batteries or connect to USB power.
• Detector (Motion Sensor): When the detector's battery is low, the host will receive a signal and the LED in the corresponding zone will flash 3 times. You can also short press the [Power Key] on the host to check for low battery status; if the LED flashes 3 times, it indicates low battery in that zone.

2. Detector Not Adding

• If the host beeps once and the LED flashes once during the adding process, the detector may have been added to another zone previously.
• If the host beeps three times and the LED flashes three times, the memory for that specific zone is full.

3. Semi-Clearing (Reset Tone/Volume)

This process resets the tone to the first one and the volume to the largest, but does not delete paired detectors.

1. Disconnect power and remove batteries from the receiver.
2. Press and hold both the [Power Key] and [Set Key] simultaneously.
3. While holding the keys, connect the receiver to power.
4. After the host beeps once and the red LED light flashes once, release the buttons.

4. Total Clearing (Factory Reset)

This process deletes all paired accessories and restores the receiver to its factory default settings.

1. Disconnect power and remove batteries from the receiver.
2. Long press the [Set Key].
3. While holding the [Set Key], connect the receiver to power.
4. Continue holding the [Set Key] and wait for a continuous slow "beep" sound and the LED to flash green light for 10 times.
5. When the host shows a fast-flashing green light, all accessories have been deleted, and factory settings are restored.

User Tips

• Optimal Placement: Experiment with different sensor heights and angles to achieve the best detection range and minimize false alarms, especially for distinguishing between human and vehicle movement.
• Expandability: The system supports up to 2 detectors per zone across 4 zones. Consider purchasing additional KERUI sensors if you need to monitor more areas.
• Range Considerations: While the wireless range is up to 1000ft in open areas, obstacles like walls and dense foliage can reduce this distance. Test the range in your specific environment during setup.
• Reliability: Users report the system works perfectly when set up correctly, emphasizing the importance of following installation guidelines.
