Vacuum the vents and outer surface of the alarm monthly using a soft brush attachment to remove dust and debris. Do not use water or cleaners.
Where should I install the smoke detector?
Install on the ceiling or wall in hallways outside bedrooms, and on every level of the home. Avoid bathrooms, kitchens, and garages to prevent false alarms.
How long does the SMI100 last?
The alarm has a 10-year service life from the date of manufacture. Replace the entire unit after 10 years.
What should I do if the alarm sounds continuously and there is no smoke?
First, check for steam or cooking fumes. Press the silence button if it's a false alarm. If the alarm continues, ventilate the area. If the problem persists, clean the alarm and test again. Replace if necessary.
