  1. FIRST START: Insert 3 pieces of 1.5V AA battery into the detector. The buzzer will make a “di” sound to notify that it’s buffering and preheating. Afterward, it will display a 2-minute counting to advise that the device is starting up.
  2. BUTTON: To check if the device is working, press the “TEST” button (LCD will display “CO 0ppm” and smoke “0.00db/m”). The LED will flicker and the detector will sound a continuous alarm, which tells you it’s working properly.
  3. PEAK RECORD: Press the “TEST ” button to check the alarm concentration registered. To clean up, you can long press the “TEST” button for more than 10 seconds.
  4. INDICATION LIGHT: Under the normal standby situation, the green light flashes one time every 35 seconds.

Installation Instructions:

  1. For maximum protection, we suggest that the alarm must be installed on each level of a multilevel home including every bedroom, hallway, finished attics, and basements or in the car.
  2. Put the alarm at both ends of the bedroom, hallway, or any large room if the size of the area is more than 30ft. (9.1m) long.
  3. If you have only one alarm, ensure it is placed in the hallway, outside of the main sleeping area, or in the main bedroom. Make sure that the alarm can be heard in all sleeping areas.
  4. Since the carbon monoxide gas is lighter than the air, choosing the suitable position for installation is
    0.3-1.0m height from floor.
  5. Avoid installing the detector close to the following sources of interference: direct airflow from vents, exhaust fans, doors, windows, sources of steam, oil vapor, etc

Areas not suitable for installation:

  1. The places always have stagnating smoke;
  2. The places with greater than 95% humidity;
  3. The places with heavy dust, heavy water mist, heavy oil mist;
  4. The places with high wind speed. (>5m/s)

Easy Installation:

  • Choose the right surface and fix the base of the detector with screws
  • Insert 3 AA batteries into the battery box following the indication of positive and negative poles.
  • Place smoke & CO alarm host on the base and screw it tight to the right.
