Setup and Installation
Proper placement and installation are crucial for the effective operation of your smoke detector. Follow these steps carefully:
1. Choosing a Location
- Install smoke detectors in every sleeping room and on every level of your home, including the basement.
- For best protection, install a smoke detector in the hallway outside of each separate sleeping area.
- Avoid installing in kitchens, bathrooms, garages, or near heating vents, as these areas can cause false alarms.
- Mount the detector on the ceiling in the center of a room or hallway. If ceiling mounting is not possible, mount it on a wall between 4 and 12 inches (10 and 30 cm) from the ceiling.
- Ensure the detector is at least 20 inches (50 cm) away from corners.

2. Silencing the Alarm
If a non-emergency alarm occurs (e.g., from cooking smoke), you can temporarily silence the alarm.
- Press the Test/Silence button once.
- The alarm will be silenced for approximately 9 minutes. The LED will continue to flash every 10 seconds during the silence period.
- After the silence period, if smoke is still present, the alarm will reactivate.
