•Locate an alarm in every room where electrical appliances are operated (i.e. portable heaters or humidifiers).
•Locate an alarm in every room where someone sleeps with the door closed. The closed door may prevent an alarm not located in that room from waking the sleeper.
•Smoke, heat, and combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling in the center of the room places it closest to all points in the room. Ceiling mounting is preferred in ordinary residential construc- tion.
•For mobile home installation, select locations carefully to avoid thermal barriers that may form at the ceiling. For more details, see MOBILE HOME INSTALLATION below.
•When mounting an alarm on the ceiling, locate it at a minimum of 4” (10cm) from the side wall (see figure 1).
•When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a minimum of 4” (10cm) and a maximum of 12” (30.5cm) below the ceiling (see figure 1).
