RECOMMENDED LOCATIONS
FOR SMOKE ALARMS
Installing Smoke Alar
ms in Single-Family Residences
The National Fire Protection Association (NFPA), recommends one Smoke
Alarm on every floor, in every sleeping area, and in every bedroom. In new
construction, the Smoke Alarms must be AC powered and interconnected.
See “Agency Placement Recommendations” for details. For additional cover-
age, it is recommended that you install a Smoke Alarm in all rooms, halls,
storage areas, finished attics, and basements, where temperatures normally
r
emain between 40˚ F (4˚ C) and 100˚ F (38˚ C). Make sure no door or other
obstruction could keep smoke from reaching the Smoke Alarms.
More specifically, install Smoke Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or
completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping
areas, install a unit in each. If a hall is more than 40 feet long (12 meters),
install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom
of the basement stairway.
Specific requirements for Smoke Alarm installation vary from state to state
and from region to region. Check with your local Fire Department for current
requirements in your area.
It is recommended AC or AC/DC units be inter-
connected for added protection.
This equipment should be installed in accordance with NFPA (National Fire
Protection Association) 72 and
101. National Fire Protection Association,
One Batterymar
ch Park, Quincy
, MA 02269-9101.
Additional local building
and regulatory codes may apply in your area. Always check compliance
requirements before beginning any installation.

AGENCY PLACEMENT RECOMMENDA
TIONS
NFP
A 72 (National Fire Code)
Smoke Alarms shall be installed in each separate sleeping r
oom, outside each
sleeping area in the immediate vicinity of the bedrooms and on each additional
story of the family living unit, including basements and excluding crawl spaces
and unfinished attics.
In new construction, Alarms shall be so arranged that operation of any one
Alarm shall cause the operation of all Alarms within the dwelling.
Smoke Detection-Are More Smoke Alarms Desirable?
The required number
of Smoke Alarms might not pr
ovide reliable early warning protection for those
ar
eas separated by a door from the areas protected by the required Smoke
Alarms. For this reason, it is recommended that the householder consider the
use of additional Smoke Alarms for those ar
eas for increased protection. The
additional ar
eas include the basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the required Smoke Alarms. The
installation of Smoke Alarms in kitchens, attics (finished or unfinished), or
garages is not normally r
ecommended, as these locations occasionally experi-
ence conditions that can result in improper operation.
LOCATIONS TO AVOID FOR SMOKE ALARMS
For best per
formance, AVOID installing Smoke Alarms in these areas:
•
Where combustion particles are produced. Combustion particles form
when something bur
ns. Areas to avoid include poorly ventilated kitchens,
garages, and furnace rooms. Keep units at least 20 feet (6 meters) from the
sour
ces of combustion particles (stove, furnace, water heater, space heater)
if possible. In ar
eas where a 20-foot distance is not possible – in modular,
mobile, or smaller homes, for example – it is recommended the Smoke
Alarm be placed as far fr
om these fuel-burning sources as possible. The
placement recommendations are intended to keep these Alarms at a rea-
sonable distance from a fuel-burning source, and thus reduce “unwanted”
alarms. Unwanted alarms can occur if a Smoke Alarm is placed dir
ectly
next to a fuel-burning source. Ventilate these areas as much as possible.
•
In air streams near kitchens. Air currents can draw cooking smoke into the
sensing chamber of a Smoke Alarm near the kitchen.
• In very damp, humid or steamy areas, or directly near bathrooms with
showers. Keep units at least 10 feet (3 meters) away from showers,
saunas, dishwashers, etc.
• Where the temperatures are regularly below 40˚ F (4˚ C) or above 100˚ F
(38˚ C) including unheated buildings, outdoor rooms, porches, or unfinished
attics or basements.
• In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly
over the stove or range. Clean a laundry room unit frequently to keep it
free of dust or lint.
• Near fresh air vents, ceiling fans, or in very drafty areas. Drafts can blow
smoke away from the unit, preventing it from reaching sensing chamber.
• In insect infested areas. Insects can clog openings to the sensing chamber
and cause unwanted alarms.
• Less than 12 inches (305 mm) away from fluorescent lights. Electrical
“noise” can interfere with the sensor.
• In “dead air” spaces. “Dead air” spaces may prevent smoke from reaching
the Smoke Alarm.
AVOIDING DEAD AIR SPACES
“Dead air” spaces may prevent smoke from reaching the Smoke Alarm. To
avoid dead air spaces, follow the installation recommendations below.
On ceilings, install Smoke Alarms as close to the center of the ceiling as
possible. If this is not possible, install the Smoke Alarm at least 4 inches (102
mm) from the wall or corner.
For wall mounting (if allowed by building codes), the top edge of Smoke
Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm)
from the wall/ceiling line, below typical “dead air” spaces.
On a peaked, gabled, or cathedral ceiling, install the first Smoke Alarm
within 3 feet (0.9 meters) of the peak of the ceiling, measured horizontally.
Additional Smoke Alarms may be r
equir
ed depending on the length, angle,
etc. of the ceiling's slope. Refer to NFPA 72 for details on requirements for
sloped or peaked ceilings.
IF YOU SUSPECT A PROBLEM
Smoke Alarms may not operate pr
operly because of dead, missing or weak
batteries, a build-up of dirt, dust or grease on the Smoke Alarm cover, or
installation in an impr
oper location. Clean the Smoke Alarm as described in
“Regular Maintenance,” and install a fr
esh battery, then test the Smoke Alarm
again. If it fails to test properly when you use the test button, or if the problem
persists, r
eplace the Smoke Alarm immediately.
•
If you hear a “chirp” approximately once a minute, replace the
batteries.
• If you experience frequent non-emergency alarms (like those caused
by cooking smoke), try relocating the Smoke Alarm.
•
If the alarm sounds when no smoke is visible, try cleaning or
r
elocating the Smoke Alarm. The cover may be dirty.
• If the alarm does not sound during testing, make sure it is receiving
AC power from the household current.
Always discharge the branch circuit before servicing an AC or AC/DC
Smoke Alar
m. First, turn off the AC power at the circuit breaker or fuse
box. Next, r
emove the battery from Smoke Alarms with battery back-up.
Finally, press and hold the test button for 5-10 seconds to discharge the
branch cir
cuit.
If the Smoke Alarm is still not operating properly, and it is still under warranty,
please see “How to Obtain Warranty Service” in the Limited Warranty.
Do not try fixing the alarm yourself – this will void your warranty!
ABOUT SMOKE ALARMS
Battery (DC) operated Smoke Alarms: Provide protection even when elec-
tricity fails, provided the batteries are fresh and correctly installed. Units are
easy to install, and do not r
equir
e pr
ofessional installation.
AC power
ed Smoke Alar
ms:
Can be inter
connected so if one unit senses
smoke, all units alarm. They do not operate if electricity fails.
AC with battery (DC) back-up: will operate if electricity fails, provided the
batteries ar
e fresh and correctly installed. AC and AC/DC units must be
installed by a qualified electrician.
ONELINK
TM
Smoke Alarms with battery (DC) back-up: Interconnects with
all ONELINK
TM
enabled Smoke and Smoke/CO Alarms without wires or con-
nectors, so when one alarm sounds, they all sound. Will operate if electricity
fails, pr
ovided the batteries are fresh and correctly installed. Units are easy to
install, and do not require professional installation.
Smoke Alarms for Solar or Wind Energy users and battery backup power
systems: AC power
ed Smoke Alarms should only be operated with true or
pure sine wave inverters. Operating this Smoke Alarm with most battery-
powered UPS (uninterruptible power supply) products or square wave or
“quasi sine wave” inverters will damage the Alar
m
. If you ar
e not sur
e about
your inverter or UPS type, please consult with the manufacturer to verify.
