FIRE SAFETY TIPS
Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters away
from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload electrical
circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys grease-
and debris-free; 6) Never leave anything cooking on the stove unattended;
7) Keep portable heaters and open flames, like candles, away from flammable
materials; 8) Don’t let rubbish accumulate.
Keep alarms clean, and test them weekly. Replace alarms immediately if they
are not working properly. Smoke Alarms that do not work cannot alert you to a
fire. Keep at least one working fire extinguisher on every floor, and an additional
one in the kitchen. Have fire escape ladders or other reliable means of escape
from an upper floor in case stairs are blocked.

and BRK

Smoke Alarms conform to regulatory
requirements, including UL217 and are designed to detect particles of
combustion. Smoke particles of varying number and size are produced
in all fires.
Ionization technology is generally more sensitive than photoelectric
technology at detecting small particles, which tend to be produced
in greater amounts by flaming fires, which consume combustible
materials rapidly and spread quickly. Sources of these fires may include
paper burning in a wastebasket, or a grease fire in the kitchen.
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced in
greater amounts by smoldering fires, which may smolder for hours
before bursting into flame. Sources of these fires may include cigarettes
burning in couches or bedding.
For maximum protection, use both types of Smoke Alarms on each
level and in every bedroom of your home.
BEFORE YOU INSTALL THIS SMOKE ALARM
IMPORTANT! Read “Recommended Locations for Smoke Alarms” and
“Locations to Avoid for Smoke Alarms” before beginning. This unit monitors
the air, and when smoke reaches its sensing chamber, it alarms. It can give
you more time to escape before fire spreads. This unit can ONLY give an early
warning of developing fires if it is installed, maintained and located where
smoke can reach it, and where all residents can hear it, as described in this
manual. This unit will not sense gas, heat, or flame. It cannot prevent or
extinguish fires.
Understand The Different Type of Smoke Alarms
Battery powered or electrical? Different Smoke Alarms provide different
types of protection. See “About Smoke Alarms” for details.
Know Where To Install Your Smoke Alarms
Fire Safety Professionals recommend at least one Smoke Alarm on every
level of your home, in every bedroom, and in every bedroom hallway or
separate sleeping area. See “Recommended Locations For Smoke Alarms”
and “Locations To Avoid For Smoke Alarms” for details.
Know What Smoke Alarms Can and Can’t Do
A Smoke Alarm can help alert you to fire, giving you precious time to
escape. It can only sound an alarm once smoke reaches the sensor.
See “Limitations of Smoke Alarms” for details.
Check Your Local Building Codes
This Smoke Alarm is designed to be used in a typical single-family home.
It alone will not meet requirements for boarding houses, apartment
buildings, hotels or motels. See “Special Compliance Considerations”
for details.

This unit will not alert hearing impaired residents. It is recom-
mended that you install special units which use devices like
flashing strobe lights to alert hearing impaired residents.
•
This Smoke Alarm must have battery power to operate.
The Smoke Alarm cannot work until you install the batteries
in the correct position (Match “+” to “+” and “-” to “-”).
• Never remove the batteries from a battery operated unit to
stop an unwanted alarm (caused by cooking smoke, etc.).
Instead open a window or fan the smoke away from the unit.
The alarm will reset automatically.
•
Do not install this unit over an electrical junction box. Only AC
powered units are intended for installation over junction boxes.
•
This Smoke Alarm has a battery drawer which resists closing

operate under DC power without batteries.
•
Do not stand too close to the unit when the alarm is sounding.
It is loud to wake you in an emergency. Exposure to the horn at
close range may harm your hearing.
•
