Align the smoke detector with the mounting bracket and twist it clockwise until it clicks securely into place. Ensure it is flush with the ceiling.
- Removing Dust Cover (If Applicable):
If your alarm came with a red dust cover (often for protection during construction or painting), ensure it is removed after all construction or renovation work is complete (at least 24 hours after). The alarm will not operate until this cover is removed.

Prova de l'alarma:
It is crucial to test your smoke alarm weekly to ensure it is functioning correctly. Press and release the central test/hush button. The alarm will sound a test pattern. Since the alarm is loud, consider standing about 2.5 feet away or using ear protection during testing.
Hush Feature:
In case of a nuisance alarm (e.g., from cooking), you can temporarily silence the alarm by pressing the test/hush button. The alarm will enter a temporary hush period.
Manteniment
Proper maintenance ensures the longevity and effectiveness of your smoke detector:
- Neteja: Clean your smoke alarm annually to prevent dust buildup from affecting its performance. Use a soft brush attachment on your vacuum cleaner to gently remove dust from the vents. Do not paint the alarm.
- Bateria: The 10-year sealed lithium battery does not require replacement for the life of the detector.
- End-of-Life Notification: At the end of its 10-year lifespan, the alarm will provide an end-of-life notification (amber LED blinks twice with two chirps every 60 seconds) to remind you it's time for replacement.
