All First Alert®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 fir
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.

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.

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.

Failure to turn off the power first may result in serious electrical shock,
injury or death.

•

This unit will not alert hearing impaired residents. It is recommended
that you install special units which use devices like flashing strobe
lights to alert hearing impaired residents.

•

Installation of this unit must conform to the electrical codes in your
area; Articles 210, 760 of NFPA 70 (NEC), NFPA 72, NFPA 101; ICC;
SBC (SBCCI); UBC (ICBO); NBC (BOCA); OTFDC (CABO), and any
other local or building codes that may apply. Wiring and installation

dimmer, or ground fault circuit interrupter. Failure to connect this unit
to a 24-hour circuit may prevent it from providing constant protection.
Unit may be connected to an arc fault circuit interrupter.

•

This Smoke Alarm must have AC or battery power to operate.
If the AC power fails, battery back-up will allow the alarm to sound
for at least 4 minutes. If AC power fails and the battery is weak,
protection should last for up to 7 days. If AC power fails and the
battery is dead or missing, the alarm cannot operate.

•

Never disconnect the power from an AC powered unit to stop an
unwanted alarm. Doing so will disable the unit and remove your
protection. In the case of a true unwanted alarm open a window or
fan the smoke away from the unit. The alarm will reset automatically
when it returns to normal operation. 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.

Be sure the circuit cannot be turned off by a switch,

•

Connect this unit ONLY to other compatible units. See “How To
Install This Smoke Alarm” for details. Do not connect it to any other

FOLLOW THESE INSTALLATION STEPS

The basic installation of this Smoke Alarm is similar whether you want
to install one Smoke Alarm, or interconnect more than one Smoke Alarm.
If you are interconnecting more than one Smoke Alarm, you MUST read
“Special Requirements For Interconnected Smoke Alarms” below before
you begin installation.

ELECTRICAL SHOCK HAZARD. Turn off power to the area where you
will install this unit at the circuit breaker or fuse box before beginning
installation. Failure to turn off the power before installation may result
in serious electrical shock, injury or death.

1. Using wire nuts, connect the power connector to the household wiring.

Improper wiring of the power connector or the wiring leading to the
power connector will cause damage to the Alarm and may lead to a
non-functioning Alarm.

STAND-ALONE ALARM ONLY:

• Connect the white wire on the power connector to the neutral wire
in the junction box.

• Connect the black wir
the junction box.

• Tuck the orange wire inside the junction box. It is used for
interconnect only.

INTERCONNECTED UNITS ONLY:
