•If you have a peaked, sloped, gabled or cathedral-style ceiling, mount your smoke alarm 4 to 36 inches (3 feet) MEASURED HORIZONTALLY FROM THE HIGHEST POINT ON THE CEILING, as shown in Figure 4.

•Do install smoke alarms in both rooms (areas) that are divided by a partial wall extending 8 or more inches down from the ceiling. See smoke alarms located in rooms B and C in Figure 4.

SPECIAL DIRECTIONS FOR INSTALLING YOUR SMOKE ALARM IN MANUFACTURED AND MOBILE HOMES

!WARNING: SMOKE ALARMS MAY BE INSTALLED ON THE CEILINGS OF MANUFACTURED AND MOBILE HOMES IF THERE IS ADEQUATE INSULATION IN THE CEILING.

Install smoke alarms on walls only between 4 and 12 inches from the ceil- ing. Install smoke alarms on inside walls in older homes or in homes where you are not sure of the insulation level. In older homes (manufactured in approximately 1976 or before) that have little or no insulation compared to today’s standards, uninsulated metal outside walls and roofs can transfer heat and cold from the outdoors, making the air right next to the wall or roof hot or cold, compared to the rest of the air inside the room. These layers of hot or cold air can prevent smoke from reaching a smoke alarm. If your mobile home has this condition, put your smoke alarm on an inside wall only, between 4 and 12 inches from the ceiling. If you are not sure about the insulation in your mobile home or if you notice the outside walls or ceiling are unusually hot or cold, put the smoke alarm on an inside wall.

WHERE YOU SHOULD NOT INSTALL SMOKE ALARMS

•Do not install a smoke alarm within close proximity of heating and cooling supply vents or within close proximity of return or fresh air vents. Smoke may be blown away from the smoke alarm by the supply vents, or could be diffused or reduced by being diverted into the return air vent. The NFPA states in Standard 72E, Section 4-4.1: “In rooms, buildings, where forced ventilation is present, detectors shall not be located where air from supply diffusers (“vents”) could dilute smoke before it reaches the detector.”

•Do not install your smoke alarm in an area where the temperature may fall below 40°F, or rise above 100°F. Smoke alarms are designed to work safely only within these temperature ranges, and failure to alarm, improper alarms or nuisance alarms may result from operation outside these temperature limits.

•Do not install a smoke alarm in a damp or very humid areas such as bathrooms with showers, where the normal humidity may rise above 93% relative humidity. Above this level, moisture may condense inside the smoke chamber and cause wrong or false alarms.

•Do not install a smoke alarm in an area where particles of combustion are normally present, such as kitchens or automobile garages, unless the smoke alarm has a False Alarm Control feature.
