4.2 Placement Guidelines
Proper placement is critical for optimal performance. Consider the following:
- Smoke Detection: For smoke, place detectors on every level of your home, inside bedrooms, and outside sleeping areas. Avoid placing near kitchens, bathrooms, or garages where cooking fumes or steam can cause false alarms.
- Carbon Monoxide Detection: For CO, place detectors on every level of your home, especially near sleeping areas and sources of CO (e.g., attached garages, furnaces, water heaters).
- General Placement:
- Mount on a wall or ceiling. If on a wall, place 4-12 inches (10-30 cm) from the ceiling.
- Avoid dead air spaces, such as at the peak of a vaulted ceiling or in corners.
- Keep away from direct sunlight, vents, fans, and areas with extreme temperatures or humidity.
- Ensure the alarm is audible from all sleeping areas.

5.2 Button Functions
- Power Button:
- Short Press: Initiates a self-test of the alarm and sensors.
- Long Press: Turns the device off when operating on battery power. (Note: Device remains on when plugged into AC).
- Screen Brightness Button:
- Short Press: Cycles through screen brightness levels.
- Long Press: Switches the temperature display between Celsius (°C) and Fahrenheit (°F).
- Buzzer Button:
- Short Press: Silences the audible alarm for a temporary period (e.g., during a false alarm). The visual alarm will typically remain active until the condition clears.
6. Alarms and Indicators
The detector provides both audible and visual alerts for hazardous conditions.
6.1 Smoke Alarm
- Audible: A loud, continuous siren (85 dB).
- Visual: The screen will display a prominent smoke icon, often with a red background or flashing.
- Action: If the smoke alarm sounds, evacuate all occupants immediately. Do not re-enter until the source of smoke has been identified and cleared, and the area is ventilated.
6.2 Carbon Monoxide (CO) Alarm
- Audible: A distinct pattern of beeps (e.g., 4 short beeps, pause, repeat).
- Visual: The screen will display the CO concentration in PPM, often with a red background or flashing, and a CO icon.
- Action: If the CO alarm sounds, move to fresh air immediately. Call emergency services or your local fire department. Do not re-enter the premises until it has been deemed safe by emergency personnel.
