Insert the 9V battery, ensuring correct polarity (+/-). A battery pull tab keeps the battery fresh until the unit is installed and activated. Once the battery is installed and the unit is connected to AC power, the detector is ready for operation.
5. Istruzzjonijiet Operattivi
Your First Alert BRK SC-9120B detector is designed for simple operation and clear indication of alarm conditions.
5.1 Buttuna Test/Silenzju
The large test/silence button on the front of the unit serves two primary functions:
- Ittestjar: Press and hold the button to test the alarm's functionality. The alarm will sound, indicating that the smoke and CO sensors are working. Test the alarm weekly.
- Issikket: In case of a nuisance alarm (e.g., from cooking smoke), press the button to temporarily silence the alarm. The alarm will reset after a few minutes if the smoke or CO levels return to normal.
- Low Battery Chirp Silence: If the unit chirps due to a low battery, pressing the button can silence the chirp for up to eight hours, allowing time to replace the battery.
5.2 Indikaturi ta' Allarm
The detector features separate latching alarm indicators for smoke and carbon monoxide. These indicators will illuminate and remain on to show which unit initiated an alarm, even after the alarm has stopped sounding. This helps in identifying the source of the alert.
6. Manutenzjoni
Regular maintenance ensures the continued reliable operation of your detector.
6.1 Sostituzzjoni tal-batterija
Replace the 9V alkaline battery at least once a year, or immediately when the low battery chirp sounds (unless silenced temporarily). Use only recommended replacement batteries.
6.2 Tindif tad-Detector Tiegħek
Dust and debris can accumulate on the detector, potentially affecting its performance. Clean your detector at least once a month:
- Gently vacuum the exterior of the alarm using the soft brush attachment of your vacuum cleaner.
- Do not use cleaning solvents or sprays directly on the unit.
6.3 Sinjal ta' Tmiem tal-Ħajja
The detector is designed with an end-of-life signal that provides an audible notification when the unit needs to be replaced. This typically occurs after 10 years of operation. When you hear this signal, replace the detector immediately.
