4. Орнотуу жана орнотуу
The OP921 is a battery-powered device. Follow these general steps for installation:
- Жайгашкан жерди тандоо: Select a suitable location on the ceiling or wall, away from corners, vents, and obstructions. Refer to local fire safety codes for specific placement guidelines.
- Монтаждык база: Secure the mounting base to the chosen location using the provided screws and anchors. Ensure the base is firmly attached.
- Батареяны орнотуу: Open the battery compartment and insert the specified batteries, observing correct polarity. Close the compartment securely.
- Детекторду тиркөө: Align the smoke detector unit with the mounting base and twist clockwise until it locks into place.
- Сыноо бирдиги: Press and hold the test button on the detector. The alarm should sound, and any visual indicators should activate. Release the button to silence the alarm.
Note: For detailed wiring instructions in a system context, consult the specific system's installation manual or a qualified technician.
5. Операция
Once installed and powered, the OP921 continuously monitors the air for the presence of smoke particles. Its photoelectric sensing chamber detects visible smoke produced by smoldering fires.
- Кадимки операция: The detector will typically have a small LED indicator that flashes periodically (e.g., every 30-60 seconds) to confirm it is functioning correctly.
- Ойготкучтун абалы: When smoke is detected above a predetermined threshold, the detector will activate its alarm. This includes a loud audible signal and a visual alarm (e.g., a rapidly flashing LED).
- Өзүн-өзү аныктоо: The built-in microprocessor continuously performs self-diagnostics to ensure internal components are working correctly. Any detected faults may trigger a specific trouble signal (e.g., a different LED flash pattern or chirp).
- Сыноо баскычы: Pressing the test button simulates a smoke condition and activates the alarm, allowing you to verify the detector's functionality.
6. Техникалык тейлөө
Үзгүлтүксүз техникалык тейлөө түтүн детекторуңуздун узак иштөөсүн жана ишенимдүүлүгүн камсыз кылат.
- Ай сайын тестирлөө: Press the test button monthly to ensure the alarm sounds. If it does not, replace the batteries or troubleshoot as necessary.
- Батареяны алмаштыруу: When the detector indicates a low battery (e.g., a chirp every 30-60 seconds, or a specific LED pattern), replace all batteries immediately with new ones of the specified type.
- Тазалоо: At least once a year, gently vacuum the exterior of the detector, especially around the sensing chamber openings, using a soft brush attachment. This removes dust and cobwebs that can interfere with detection. Do not use cleaning sprays or solvents.
- Боёбоо: Painting the detector can block the sensing chamber and prevent it from detecting smoke.
