ceiling, locate it at a minimum of 4” (10cm) from
the side wall (see Diagram A). If installing 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 Diagram A).
Sloped Ceiling Installation:
The following information is from the National Fire Protection Association and is listed in Fire Code 72. Install Smoke Alarms on sloped, peaked or cathedral ceilings at, or within 3ft (0.9m) of the highest point (measured horizontally). NFPA 72 states “Smoke alarms in rooms with ceiling slopes greater than 1 foot
to 8 feet (.3
NFPA 72 states “A row of alarms shall be spaced and located within 3 ft (0.9 m) of the peak of the ceiling measured horizontally.” (See Diagram B)

Mobile Homes:
Mobile homes built within the last five to seven years are designed to be energy efficient. Install Smoke/CO alarms as recommended above. (Refer to Recommended Installation Instructions and Diagram A) In mobile homes that are not well insulated, extreme heat or cold can be transferred from the outside to the inside through poorly insulated walls and roof. This may cause a thermal barrier, which can prevent smoke from reach- ing an alarm mounted on the ceiling. In such mobile homes install your Smoke/CO Alarm on an inside wall with the top edge of the alarm at a minimum of 4 inch- es (10cm) and a maximum of 12 inches (30.5cm) below the ceiling. (See Diagram A) If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and ceiling are either hot or cold, install your alarm on an inside wall ONLY!
