1. Úvod
The CPVan BRJ-502D is an independent combustible gas alarm designed to continuously monitor the concentration of indoor gas leakage. Utilizing advanced gas-sensitive sensing technology and a cost-effective microprocessor, this device provides reliable protection against potential hazards such as poisoning, explosions, and fires caused by gas leaks. When the leakage concentration reaches a preset alarm level, the detector activates a sound and light alarm. The device automatically returns to normal operation once the gas concentration falls below the alarm threshold, ensuring continuous safety for your home.
2. Důležité bezpečnostní informace
- Před instalací a použitím si pečlivě přečtěte všechny pokyny.
- Toto zařízení je určeno pouze pro vnitřní použití.
- Do not install the detector in areas with high humidity, excessive dust, or direct exposure to steam or oil fumes, as this may affect its performance.
- Avoid placing the detector near ventilation openings, doors, or windows, which could dilute gas concentrations and delay detection.
- Do not paint the detector or block its ventilation holes.
- Regularly test the detector to ensure proper functioning.
- In case of an alarm, immediately ventilate the area, turn off gas sources, and contact emergency services if necessary.

5. Nastavení a instalace
- Unpack the Detector: Carefully remove the gas detector from its packaging.
- Vyberte místo instalace:
- For natural gas (lighter than air): Install the detector 30cm below the ceiling, within 1.5 meters horizontally from the gas source.
- For LPG (heavier than air): Install the detector 30cm above the floor, within 1.5 meters horizontally from the gas source.
- Avoid areas near windows, doors, ventilation fans, or areas with high humidity or steam.
- Plug In the Detector: Insert the EU plug of the detector directly into a standard AC100V~AC240V wall socket.
- Úvodní rozcvička: Upon plugging in, the detector will enter a warm-up phase. The POWER (green) LED will illuminate, and the STATE (yellow/orange) LED may flash or remain steady. The LCD display might show a countdown or '0'. This phase typically lasts a few minutes.
- Připraveno k provozu: Once the warm-up is complete, the POWER (green) and STATE (yellow/orange) LEDs should be steady, and the LCD display should show '0' (indicating no gas detected). The detector is now operational.
6. Návod k obsluze
Normální provoz:
During normal operation, the green POWER LED and yellow/orange STATE LED will be steadily lit. The LCD display will show '0', indicating that no combustible gas is detected in the environment.
Stav alarmu:
If the detector senses a combustible gas concentration reaching the alarm threshold:
- The red ALARM LED will flash.
- An audible alarm (≥85dB) will sound continuously.
- The LCD display will show the detected gas concentration level.
Action during Alarm:
- Okamžitě otevřete všechna okna a dveře, abyste prostor vyvětrali.
- Turn off all gas appliances and the main gas supply valve.
- Do not operate electrical switches, light matches, or create any ignition sources.
- If the alarm persists, evacuate the premises and contact your gas supplier or emergency services.
Funkce autotestu:
The detector may have a self-test button (often the large circular button on the front). Press and hold this button briefly to initiate a self-test. The device should emit a test alarm sound and flash its LEDs to confirm functionality. Refer to the specific product for exact self-test procedures.
7. Údržba
- Pravidelný úklid: Gently wipe the exterior of the detector with a soft, damp cloth. Do not use harsh detergents, solvents, or abrasive cleaners. Ensure no liquid enters the ventilation holes.
- Vyhněte se překážkám: Ensure that the ventilation holes on the detector are not blocked by dust, dirt, or other objects.
- Pravidelné testování: Test the detector at least once a month using the self-test function to ensure the alarm and indicators are working correctly.
- Sensor Longevity: Gas sensors have a limited lifespan. While this device uses a high-quality semiconductor sensor, it is recommended to replace gas detectors every 5-7 years for optimal performance.
8. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Detektor se nezapne | No power to the socket; device malfunction. | Check the power supply to the socket. Try plugging into a different working socket. If still no power, the device may be faulty. |
| Falešné poplachy | Interference from strong odors (e.g., alcohol, cleaning agents, aerosols); detector placed too close to gas appliances. | Ventilate the area. Relocate the detector if it's too close to sources of strong fumes. Ensure proper installation location as per section 5. |
| Alarm zní nepřetržitě bez přítomnosti plynu | Sensor contamination or end-of-life. | Clean the detector. If the issue persists after ventilation and cleaning, the sensor may be faulty or at the end of its operational life. Consider replacing the unit. |
| LCD display shows error code or abnormal reading | Vnitřní závada nebo problém se senzorem. | Unplug the detector for 30 seconds and plug it back in. If the error persists, the device may require replacement. |
9. Uživatelské tipy
- For optimal performance, ensure the detector is installed at the correct height relative to the type of gas you are monitoring (natural gas is lighter than air, LPG is heavier).
- Regularly check the power indicator to confirm the device is receiving power.
- Avoid placing the detector in direct sunlight or near heat sources, as this can affect sensor accuracy.
