INTRODUCTION
Thank you for choosing BRK Brands, Inc. for your Smoke Alarm needs.
You have purchased a state-of-the-art Smoke Alarm designed to provide
you with early warning of a fire.
Key features include:
Smart Technology designed to help reduce unwanted or nuisance alarms.
Single Button Test/Silence eliminates confusion. Depending on what
mode the alarm is in, pushing the button provides different functions such
as testing the alarm, silencing the alarm, re-testing the alarm when in
silence and clearing the Latching feature.
Latching Alarm Indicator easily identifies initiating alarm even after the
alarm condition has subsided.
Perfect Mount System includes a gasketless base for easy installation and
a new mounting bracket that keeps the alarm secure over a wide rotation
range to allow for perfect alignment.
Dust Cover is included to keep the alarm clean during construction.
Easy Installation/Maintenance features include a large opening in the
mounting bracket for easy access to wiring. A battery pull tab keeps the
battery fresh until the home is occupied. A Side Load Battery Drawer allows
for easy battery replacement without removing the alarm from the ceiling or
wall (Model 9120B only).
Improved UV Resistance keeps the alarm from discoloring over time.
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 addi-
tional one in the kitchen. Have fire escape ladders or other reliable means of
escape from an upper floor in case stairs are blocked.
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.

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.
