Where to install smoke alarms:
1. At first, you need to install them in your bedroom and route way, and should install at least one item in every bedroom.
2. Stairway is important for you to rush out when fires occur, so smoke detectors must be installed there as Diagram 1 shows.
3. You have at least require one smoke alarm on every floor, including finished attics and basements.
4. Install one alarm beside every electric facility.
5. Install smoke alarms in the middle of the ceiling, because smog, heat, and flashes are always through the roof of rooms.
6. If some reasons cause you can’t install them in the middle of the ceiling, you need to install them at least 10cm away from the wall.
7. If you like to install them on the wall, they should be installed 10-30.5cm away under the ceiling as Diagram 2 shows.
8. You need to install more than one alarm when the length of your hall exceeds 9m.
9. In a triangle roof room, install the alarm 0.9m away from the top as Diagram 3 shows.
10. How to install smoke alarms in a removable house. The removable house is short of heat isolation, so you’d better install the alarm 10-30.5cm away from the ceiling. For safety, you also need to install another one near your bedroom.
