4. Producto terminadoview
The system consists of two main components: the Receiver and the PIR Motion Sensor.
4.1. Receptor
The receiver is the central unit that produces audible alerts and visual flashes when triggered by the motion sensor. It features controls for mode selection, volume adjustment, and chime tone selection.

- Mode Change Button (M): Recorre diferentes modos de funcionamiento.
- Volume Control Button (V): Adjusts the alert volume (4 levels: High/Middle/Low/Mute).
- Chime Selection Button (Music Note): Selects from 32 different ringtones.
- Indicador LED: Flashes upon detection.
- Compartimento de la batería: Requiere 3 pilas AAA.
- Puerto de alimentación USB: For optional external power supply (DC-5V).
4.2. Sensor de movimiento PIR
The PIR (Passive Infrared) motion sensor detects movement within its detection range and sends a signal to the receiver. It is designed for indoor use.

- Lente PIR: Detects infrared changes caused by movement.
- Indicador LED: Flashes when motion is detected.
- Compartimento de la batería: Requiere 2 pilas AAA.
- Puerto de alimentación USB: For optional external power supply (DC-5V).
5. Configuración
5.1. Alimentación de los dispositivos
Both the Receiver and the Motion Sensor can be powered by AAA batteries or an optional USB power cable (DC-5V).
Image: Illustration of battery and USB power options for the Receiver and Motion Sensor.
- Instalación de la batería del receptor: Open the battery compartment on the back of the receiver. Insert 3 AAA alkaline batteries, ensuring correct polarity. Close the compartment.
- Motion Sensor Battery Installation: Open the battery compartment on the back of the motion sensor. Insert 2 AAA alkaline batteries, ensuring correct polarity. Close the compartment.
- Alimentación USB (opcional): Connect a DC-5V USB power cable to the respective USB ports on the Receiver and/or Motion Sensor.
Note: After changing batteries, the motion detector may need to be re-paired with the receiver if the receiver does not have memory function.
5.2. Montaje del sensor de movimiento
The motion sensor is wall-mountable. Choose a location that provides optimal detection coverage and minimizes false alarms.
Imagen: Examples of mounting locations for the motion sensor and placement for the receiver.
- Mount the sensor in a position where it can detect movement in the desired area (e.g., doorway, entryway).
- Adjust the sensor's angle to avoid false alarms from pets or moving objects.
- Ensure a clear line of sight between the sensor and the receiver for optimal communication range (up to 450ft in open air).
- Avoid direct sunlight on the sensor. If used outdoors, place it under an overhang or covered area, as it is not waterproof.
6. Instrucciones de funcionamiento
6.1. Cambio de modos de funcionamiento
The receiver has multiple operating modes. Press the 'M' (Mode Change) button on the side of the receiver to cycle through the modes:
Video: Demonstrates the different operating modes (Doorbell, Alarm, Welcome, Night Light) and how to switch between them on the KERUI M7 system.
- Modo de timbre: The receiver plays a selected chime when motion is detected.
- Modo de alarma: The receiver emits a loud alarm sound when motion is detected, suitable for security alerts.
- Modo de bienvenida: The receiver plays a "Hello, welcome" voice message when motion is detected, ideal for storefronts or entryways.
- Modo de luz nocturna: The receiver's LED light illuminates when motion is detected, providing a visual alert or temporary lighting.

6.2. Ajuste del volumen
Press the 'V' (Volume Control) button on the side of the receiver to cycle through 4 volume levels: High, Middle, Low, and Mute (0-80dB).
6.3. Selecting Chime Tones
Press the 'Music Note' button on the side of the receiver to choose from 32 different ringtones. Continue pressing until you find your preferred tone.
6.4. Rango de detección
The PIR motion sensor has a detection range of approximately 2-8 meters (6-26 feet). The communication range between the sensor and receiver is up to 450 feet in open air.

7. Mantenimiento
- Reemplazo de batería: Replace batteries in both the receiver and motion sensor when performance decreases (e.g., no red light, no signal, reduced detection distance). Use high-capacity AAA alkaline batteries for extended life.
- Limpieza: Limpie los dispositivos con un paño suave y seco. No utilice limpiadores abrasivos ni disolventes.
- Colocación de sensores: Periodically check the sensor's angle and position to ensure optimal performance and to avoid false alarms. If necessary, adjust the sensor to a higher position and angle it downwards.
- Sensitivity Adjustment (Advanced): If experiencing persistent false alarms, consider covering a small portion of the sensor area with black tape to reduce sensitivity.
8. Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| Motion sensor not detecting / No red light | Baterías bajas o agotadas. Instalación incorrecta de la batería. | Replace batteries in the motion sensor. Ensure batteries are inserted with correct polarity. |
| Receiver not chiming/alarming | Low or dead batteries in receiver. Receiver is muted. Sensor not paired (after battery change). Out of range. Interference. | Replace batteries in the receiver. Adjust volume. Re-pair sensor and receiver if needed. Move receiver closer to sensor. Reduce interference sources. |
| Reduced detection distance | Low batteries. Obstructions. Environmental factors (e.g., direct sunlight). | Replace batteries. Ensure clear line of sight. Reposition sensor to avoid direct sunlight or other environmental factors. |
| Alarmas falsas | Sensor angle too wide. Pets or moving objects triggering sensor. Wind. | Adjust sensor angle. Mount sensor higher and angle downwards. Avoid placing in windy areas. Consider reducing sensitivity with tape if necessary. |
