Mobile Home Installation:

For minimum protection, smoke alarms  should be installed in compliance with H .U .D . Manu-
factured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 
3282 . For additional protection, see Single Story Residence smoke alarm requirements/rec-
ommendations for Existing Homes and New Construction Homes .
Note: For mobile homes built before 1978, install smoke alarms or combination alarms on in-
side walls between 4” and 12” from the ceiling (older mobile homes have little or no insulation 
in the ceiling). This is especially important if the ceiling is unusually hot or cold.
Install smoke alarms or combination alarms inside each bedroom and in the hallway outside 
each separate sleeping area .

RECOMMENDED PLACEMENT:

NOTE:

 For any location, make sure no door or other obstruction could prevent the 

smoke or carbon monoxide from reaching the alarm .

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Installation in an improper location can affect the sensitive electronic components in this alarm . 

This alarm is not suitable for installation in hazardous locations as defined in the National Electri-

cal Code . 

To avoid causing damage to this alarm, to provide maximum protection, and to prevent 
unnecessary alarms, DO NOT LOCATE THIS ALARM:

•  In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or show-

er, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other source of 

high humidity .

•  In very cold or very hot environments or in unheated buildings or outdoor rooms where the 

temperature can go below or above the operating range of the alarm .

•  In garages, kitchens crawl spaces and unfinished attics. 
•  In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air returns or 

open windows . Blowing air may prevent smoke or CO gas from reaching the sensors . 

•  In extremely dusty, dirty or greasy areas . Installation in these areas could lead to nuisance 

alarms, may expose the sensor to substances which could damage or contaminate the 

alarm .

•  In the garage, vehicle exhaust can contain some carbon monoxide . These levels are higher 

when the engine is first started. Within hours of starting a vehicle and backing it out of the 

garage, the levels present over time can activate the alarm and become a nuisance .
