Testing the Detector:
It is recommended to test your smoke detector weekly. Press and hold the Test/Silence button until the alarm sounds. The voice alert will announce "Fire!" in English and "Incendie!" in French, followed by a loud siren. Release the button to stop the alarm.
Silencing a Nuisance Alarm:
If a non-emergency event (e.g., cooking smoke) triggers the alarm, press the Test/Silence button to temporarily silence it for approximately 10 minutes. The detector will automatically reset after the silence period if the smoke has cleared. If smoke is still present, the alarm will reactivate.

5. Maintenance
Cleaning Your Detector:
Dust and debris can accumulate on the smoke detector and affect its performance. Clean your detector at least once a month:

- Wipe the cover with a clean, damp cloth. Do not use cleaning solvents or sprays.
End of Life Indication:
The SITERWELL GS886-H04 is equipped with a 10-year sealed battery. After approximately 10 years of operation, the detector will emit an end-of-life signal (typically a series of chirps) to indicate that it needs to be replaced. Replace the entire unit promptly when this occurs.

| Nuisance alarms (false alarms) | Cooking fumes, steam, dust, or high humidity. | Press the Test/Silence button. Relocate the detector if nuisance alarms persist in a specific area. Ensure proper ventilation during cooking. |
| Detector does not sound during test | Battery not activated or unit is faulty. | Ensure the detector is properly twisted onto the mounting bracket to activate the battery. If still unresponsive, replace the unit. |
| Red LED flashes but no alarm sound | Faulty speaker or internal issue. | Replace the smoke detector unit. |
