TROUBLESHOOTING GUIDE
If the Alarm... Problem... You should...
Horn "chirps" about once per minute;
Voice: "Replace battery in [Location]" every 5
hours Low battery warning. Install two new AA batteries*.
Horn does three rapid "chirps" every minute;
Voice: "Detector error in [Location, example
"Kitchen"], please see manual" repeated every
5 hours; LED has 3 rapid flashes with "chirps". MALFUNCTION SIGNAL. Device is not working
properly, and needs to be replaced. Units under warranty should be returned to
manufacturer for replacement. See “Limited
Warranty” for details.
The Alarms are linked but do not communicate
with each other. Possible interference. Reference the Wireless
Operation section of this manual. Move Alarms to different locations. Add an
additional Alarm between the unresponsive
Alarms to route the signal around obstructions.
Carbon Monoxide Alarm ONLY:
CO Alarm goes back into alarm 4 minutes after
you Silence it. CO levels indicate a potentially dangerous
situation. IF YOU ARE FEELING SYMPTOMS OF CO
POISONING, EVACUATE your home and call
911 or the Fire Department. Refer to "If The CO
Alarm Sounds" for details.
CO Alarm sounds frequently even though no high
levels of CO are revealed in an investigation. The CO Alarm may be improperly located. Refer
to “Where to Install This Alarm” for details. Relocate your Alarm. If frequent alarms
continue, have home rechecked for potential
CO problems. You may be experiencing an
intermittent CO problem.
Smoke Alarm ONLY:
Smoke Alarm sounds when no smoke is visible. Unwanted alarm may be caused by non-
emergency source like cooking smoke. Silence Alarm using manual button; clean the
Alarm’s cover with a soft, clean cloth. If frequent
unwanted alarms continue, relocate your Alarm.
Alarm may be too close to a kitchen, cooking
appliance, or steamy bathroom.
*For a list of acceptable replacement batteries, see “Regular Maintenance.”

This Smoke/CO Alarm is intended for residential use. It is not intended
for use in industrial applications where Occupational Safety and Health
Administration (OSHA) requirements for Carbon Monoxide Alarms must
be met. The Smoke Alarm portion of this device is not intended to alert
hearing impaired residents. Special purpose Smoke Alarms should be
installed for hearing impaired residents (CO Alarms are not yet available
for the hearing impaired).
Smoke/CO Alarms may not waken all individuals. Practice the escape
plan at least twice a year, making sure that everyone is involved – from
kids to grandparents. Allow children to master fire escape planning and
practice before holding a fire drill at night when they are sleeping.
If children or others do not readily waken to the sound of the Smoke/CO
Alarm, or if there are infants or family members with mobility limitations,
make sure that someone is assigned to assist them in fire drill and in the
event of an emergency. It is recommended that you hold a fire drill while
family members are sleeping in order to determine their response to the
sound of the Smoke/CO Alarm while sleeping and to determine whether
they may need assistance in the event of an emergency.
Smoke/CO Alarms cannot work without power. Battery operated units
cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used, or if the batteries are not installed correctly.
AC units cannot work if the AC power is cut off for any reason (open fuse
or circuit breaker, failure along a power line or at a power station, electrical
fire that burns the electrical wires, etc.). If you are concerned about the
limitations of battery or AC power, install both types of units.
This Smoke/CO Alarm will not sense smoke or CO that does not
reach the sensors. It will only sense smoke or CO at the sensor. Smoke
or CO may be present in other areas. Doors or other obstructions may
affect the rate at which CO or smoke reaches the sensors. If bedroom
doors are usually closed at night, we recommend you install an alarm
device (Combination CO and Smoke Alarm, or separate CO Alarms and
Smoke Alarms) in each bedroom and in the hallway between them.
This Smoke/CO Alarm may not sense smoke or CO on another level
of the home.
Example: This alarm device, installed on the second floor,
may not sense smoke or CO in the basement. For this reason, one
alarm device may not give adequate early warning.
Recommended minimum protection is one alarm device in every
sleeping area, every bedroom, and on every level of your home. Some
experts recommend battery powered Smoke and CO Alarms be used in
conjunction with interconnected AC powered Smoke Alarms. For details,
see “About Smoke Alarms” for details.
Smoke/CO Alarms may not be heard. The alarm horn loudness meets or
exceeds current UL standards of 85 dB at 10 feet (3 meters). However, if
the Smoke/CO Alarm is installed outside the bedroom, it may not wake up
a sound sleeper or one who has recently used drugs or has been drinking
alcoholic beverages. This is especially true if the door is closed or only
partly open. Even persons who are awake may not hear the alarm horn
if the sound is blocked by distance or closed doors. Noise from traffic,
stereo, radio, television, air conditioner, or other appliances may also
prevent alert persons from hearing the alarm horn. This Smoke/CO Alarm
is not intended for people who are hearing impaired.
The Alarm may not have time to alarm before the fire itself causes
damage, injury, or death, since smoke from some fires may not
reach the unit immediately. Examples of this include persons
smoking in bed, children playing with matches, or fires caused by
violent explosions resulting from escaping gas.
This Smoke/CO Alarm is not a substitute for life insurance.
Though this Smoke/CO Alarm warns against increasing CO levels or the
presence of smoke, BRK Brands, Inc. does not warrant or imply in any
way that they will protect lives. Homeowners and renters must still insure
their lives.
This Smoke/CO Alarm has a limited life. Although this Smoke/CO
Alarm and all of its parts have passed many stringent tests and are
designed to be as reliable as possible, any of these parts could fail at
any time. Therefore, you must test this device weekly. The unit should
be replaced immediately if it is not operating properly. All Smoke/CO
Alarms need to be replaced every 5 years. All Smoke Alarms need to be
replaced every 10 years.
This Smoke/CO Alarm is not foolproof. Like all other electronic
devices, this Smoke/CO Alarm has limitations. It can only detect smoke
or CO that reaches the sensors. It may not give early warning of the
source of smoke or CO is in a remote part of the home, away from the
alarm device.
