Mobile Home Installation:
For minimum protection, smoke alarms should be installed in compliance with H.U.D.
Manufactured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and
Section 3282. For additional protection, see Single Story Residence smoke alarm require-
ments/recommendations for Existing Homes and New Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms or combination alarms on
inside 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.
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
Electrical 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 3 feet (0.9m) from a bath or
shower, 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, 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 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.
• Within 6 feet (1.8m) of heating or cooking appliances. To reduce nuisance alarms, we
recommend 15 feet (4.6m).
• Less than 12 inches (306mm) away from fluorescent lights. Electrical noise can interfere
with the operation of the alarm.
• In the kitchen, some gas appliances can emit a short burst of CO or gas upon startup. This
is normal. If this alarm is installed too close to these appliances, it may sound often and
become a nuisance.
• Less than 20 feet (6m) from the sources or combustion particles such as a stove, furnace,
water heater, non-electric space heater. In areas where a 20 foot (6m) distance is not
possible i.e. modular, mobile or smaller homes, it is recommended the alarm be placed as
far from these fuel-burning sources as possible.
• Where heavy furniture drapes or other objects will not block the sensor.
• Peaks of vaulted ceilings, “A” frame ceilings or gabled roofs.
• Alarms are not to be used with detector guards unless the combination has been evaluated
and found suitable for that purpose.
• Do not install this alarm into an electrical circuit controlled by a dimmer or switch or ground
fault circuit interrupter.
NOTES:
Good ventilation is recommended when household cleaning supplies or similar
contaminants are used.
