CHAPTER 10: General Limitations Of This Alarm
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 may not be available for the hearing impaired).
This smoke/CO alarm will not work without
power. This alarm requires a 9V alkaline or lithium
battery to operate.
This smoke/CO alarm will not sense carbon
monoxide or smoke that does not reach the
sensors. It will only sense CO or smoke at the sensor.
CO or smoke 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 smoke/CO alarm, or
separate smoke and CO alarms) in each bedroom
and in the hallway between them.
This smoke/CO alarm may not sense CO or
smoke on another level of the home. Example: This
alarm device, installed on the second floor, may not
sense CO or smoke 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 “Different
Types of Smoke Alarms” (see page 24 for details).
This smoke/CO alarm may not be heard. The alarm
horn loudness meets or exceeds the current UL
standards. However, if the device 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 alarm device is not
intended for people who are hearing impaired.
The smoke 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
the 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.
This smoke/CO alarm is not foolproof. Like all
other electronic devices, this smoke/CO alarm has
limitations. It can only detect CO or smoke that
reaches the sensors. It may not give early warning of
the source of CO or smoke is in a remote part of the
home, away from the alarm device.
