IMPORTANT SAFETY INFORMATION
About this Alarm
This combination alarm has separate sensors to detect smoke and carbon monoxide (CO).
The smoke alarm has priority over the CO alarm.
The combination smoke/CO alarm is designed to be used in ordinary indoor locations of
single-family households only.
The sensitivity of both the smoke and CO sensors and the horn patterns for both warnings,
comply with UL standards.
This combination smoke/CO alarm can be used as a replacement for all USI ELECTRIC
Smoke and CO Alarms without additional wiring. This allows the user to easily upgrade
from individual smoke or CO alarms to a combination unit.
WHAT YOU SHOULD KNOW ABOUT CARBON MONOXIDE (CO)
Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is
a cumulative poison. Even low levels of CO have been shown to cause brain and other vital
organ damage in unborn infants with no effect on the mother.
The following symptoms are related to CARBON MONOXIDE POISONING and should be
discussed with ALL members of the household:
MILD EXPOSURE
Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).
MEDIUM EXPOSURE
Severe throbbing headache, drowsiness, confusion, fast heart rate.
EXTREME EXPOSURE
Unconsciousness, convulsions, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware
they are not well, but they become so disoriented that they are unable to save themselves
by either exiting the building or calling for assistance. Young children and household pets
may be the first affected.
Your combination smoke/CO alarm is designed to detect the toxic CO fumes that result
from incomplete combustion, such as those emitted from appliances, furnaces, fireplaces
and auto exhaust.
This alarm will only indicate the presence of carbon monoxide gas surrounding its sensor.
Carbon monoxide gas may be present in other areas.
This product is intended for use in ordinary indoor locations of family living units. It is not
designed to measure compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards. Individuals with medical problems may consider
using warning devices which provide audible and visual warnings for carbon monoxide
concentrations under 30 PPM.
WHAT YOU SHOULD DO IF THE CO ALARM SOUNDS
Never disconnect a combination Smoke/CO alarm to silence an alarm. The alarm will
automatically sense when the level of CO in the air falls below the danger level. You should
stay outside the residence in fresh air until the alarm is silenced. When the alarm sounds,
do not stand too close to the alarm. The sound produced by the alarm is loud because it is
designed to awaken a person in an emergency. Prolonged exposure to the alarm at a close
distance may be harmful to your hearing.
Two self-adhesive labels have been provided with instructions indicating what to do if the
CO alarm sounds. Add the phone numbers of your emergency services provider and a
qualified technician to each label. Place one of the labels in a visible area next to the alarm
and place the other label near a source of fresh air which will be used as a gathering place
if the alarm sounds.
