4. Настройка і ўстаноўка
4.1. Умовы ўстаноўкі
- Avoid installing the detector outdoors. It is designed for indoor use only and is not waterproof.
- Do not install in places with pets, near air conditioners, heat sources, or in areas exposed to direct sunlight or under rotating objects, as these can cause false alarms.
- The mounting surface must be solid and free from vibration to ensure stable detection.
- Install the detector in a location where an intruder would most likely pass through the detection area.
4.2. Этапы ўстаноўкі
- Устаўце батарэі: Open the battery compartment and insert two 1.5V AAA batteries. The detector can also be powered via a DC-5V USB adapter.
- Выберыце месца ўстаноўкі: Choose an appropriate height and location for the detector bracket based on the desired detection area (refer to Section 4.1 and Figure 2).
- Кранштэйн для мацавання: Securely fix the mounting bracket to the chosen surface.
- Падключыце дэтэктар: Fix the rear cover of the detector onto the mounted bracket. The bracket allows for 360-degree rotation and the sensor itself has a 15-degree downward tilt for optimal curtain detection.
5. Аперацыя
5.1. LED Indicator Analysis
| Дзяржава | Святлодыёдны індыкатар |
|---|---|
| Уключэнне | Red light stays on for 5 seconds. |
| Адключэнне | No instructions (LED off). |
| Зарадка | Red light is on during charging and goes out when fully charged. |
| Інфрачырвонае выяўленне | Red light on for 1 second. |
| Нізкі зарад батарэі | Red light flashes quickly for 3 seconds. |
Заўвага: The detector senses only once within 5 seconds to conserve power and prevent continuous triggering.
5.2. Detection Range and Application
The detector provides a curtain-style detection area, typically covering 8-12 meters with a 110-degree angle. This makes it ideal for protecting specific entry points like windows and doors.
6. Тэхнічнае абслугоўванне
- Уборка: Do not touch the sensor surface directly to avoid affecting its sensitivity. If cleaning is necessary, disconnect the power supply (remove batteries or unplug USB) and gently wipe the surface with a soft cloth dampз невялікай колькасцю алкаголю.
- Замена батарэі: Replace the 2xAAA batteries when the low battery indicator (red light flashes quickly for 3 seconds) is observed. Battery life is approximately 1 year under normal conditions.
- Рэгулярнае тэставанне: To ensure the detector functions normally, test it periodically, ideally once a week.
- крыніца харчавання: Ensure a stable power supply, either through fresh batteries or a reliable USB adapter connection.
7. Выпраўленне непаладак
- Ілжывыя трывогі:
- Check installation location: Ensure it's not near heat sources (vents, direct sunlight), air conditioners, or rotating objects (fans).
- Verify mounting stability: A vibrating surface can cause false triggers.
- Consider environmental factors: While designed to be pet-immune to some extent, large pets or specific movements might trigger it. Re-evaluate placement if pets are an issue.
- Няма выяўлення:
- Check battery level: Replace batteries if the low battery indicator is active.
- Ensure proper power: If using USB, check the adapter and cable.
- Verify sensor surface cleanliness: Dust or obstructions can reduce sensitivity. Clean as per maintenance instructions.
- Confirm correct installation height and angle: Refer to installation diagrams for optimal coverage.
- Check compatibility with alarm host: This sensor operates at 433MHz. Ensure your alarm system supports this frequency and is properly paired.
- Праблемы сумяшчальнасці:
- This sensor is primarily designed for KERUI alarm systems. While it may work with other 433MHz systems, compatibility is not guaranteed.
- A control panel (alarm host) is required for the sensor to function as part of a security system and send alerts. It does not operate independently as a standalone alarm.
8. Карыстальніцкія парады
- Параметры харчавання: The sensor can be powered by either 2xAAA batteries or a DC-5V USB adapter, offering flexibility in placement and ensuring continuous operation.
- Сістэмная інтэграцыя: For full functionality, including remote activation and notifications, connect the sensor to a compatible KERUI alarm host or another 433MHz alarm system.
- Аптымальнае размяшчэнне: For curtain-style detection, ensure the sensor is positioned to create an invisible barrier across the area you wish to protect (e.g., across a window or doorway).
- Рэгулярныя праверкі: Periodically test the sensor's functionality and check battery status to maintain optimal security.
