1. Smoke Alarm: What To Do When The Alarm Sounds
The smoke alarm pattern is three long beeps with voice “Fire!,” a 1.5 second pause, and three long beeps repeating.
The red LED blinks in time with the alarm pattern only on the alarm(s) that detected the hazard (initiating alarm).
The smoke alarm takes precedence when both smoke and carbon monoxide are present.
•Alert small children in the home as well as anyone else that might have difficulty recognizing the impor-
tance of the alarm sounding or that might have difficulty leaving the area without help.
•Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or
picking up valuables.
•While leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping
through cracks, don’t open that door! Instead, use your alternate exit. If the inside of the door is cool, place
your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
•If the escape route requires you to go through smoke, stay close to the floor where the air is cleaner. Crawl
if necessary, and breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make sure everyone is there.
•Call the fire department or 911 from your cell phone outside, or from your neighbor’s home-not from yours!
•Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

2. Carbon Monoxide Alarm: What To Do When The Alarm Sounds
The carbon monoxide (CO) alarm pattern is four quick beeps with voice “Warning! Carbon Monoxide”
repeating every 5 seconds. The red LED blinks in time with the alarm pattern. After 4 minutes in CO alarm
the alarm pattern and voice will only occur every 60s.
WARNING: ACTUATION OF YOUR CO ALARM INDICATES THE PRESENCE OF
CARBON MONOXIDE CO WHICH CAN KILL YOU. IF THE ALARM SIGNAL SOUNDS:
1 Operate the Test/Hush® button. NOTE: Pressing the button on the alarming unit will silence the
alarm notification. If the unit goes into alarm mode again within six minutes, it is sensing high levels
of CO which can quickly become a dangerous situation.
2 Call your emergency services (Fire Department or 911). EMERGENCY PHONE #:___________
3 Immediately move to fresh air —outdoors or by an open door/ window. Do a head count to check
that all persons are accounted for. Alert small children in the home as well as anyone else that might
have difficulty recognizing the importance of the alarm sounding or that might have difficulty leaving
the area without help. Do not reenter the premises or move away from the open door/window until
the emergency services responders have arrived, the premises have been aired out, and your alarm
remains in its normal condition.
4 After following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and
call a qualified appliance technician to investigate sources of CO from fuel burning equipment and
appliances, and to inspect for proper operation of equipment.
If problems are identified during this inspection, have the equipment serviced immediately. Note any
combustion equipment not inspected by the technician and consult the manufacturer’s instructions,
or contact the manufacturer directly for more information about CO safety and the equipment. Make
sure that motor vehicles are not, or have not been, operating in a garage attached or adjacent to the
residence. Never restart the source of a CO problem until it has been corrected. Never ignore the sound
of the alarm!
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

5. Introduction, Product Features And Specifications
Introduction
This alarm detects products of combustion using a multi-criteria optical sensor and carbon monoxide using an
electrochemical cell. Many times throughout this User Guide, we will refer to Carbon Monoxide as “CO.”
Ten (10) years after the unit was installed, this unit will automatically alert you that it is time to replace the unit.
This is called “End of Unit Life” mode. See Troubleshooting Guide. To help identify the date to replace the unit,
a label has been affixed to the side of the alarm. Write the “Install date” in the space provided, and then write
in the “Replace by” date (10 years from initial power up) in permanent marker on the label prior to installing the
unit. Two labels have been provided that have important information on what to do in case of a CO alarm. Place
one label at eye level on a wall near the alarm after it is mounted, and one near a fresh air source such as a door
or window.

6. Limitations Of Smoke And Carbon Monoxide Alarms
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•Life safety from fire in residential occupancies is based primarily on early notification to occupants of the need to
escape, followed by the appropriate egress actions by those occupants.
•There are situations where a smoke alarm may not be effective to protect against fire as stated in the NFPA
Standard 72. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as gasoline
•Fire warning systems for dwelling units are capable of protecting about half of the occupants in potentially fatal
fires. A smoke alarm may not be effective in some situations, such as during incendiary fires where the fire grows
so rapidly that an occupant’s egress is blocked even with properly located smoke alarms, or when victims are
intimate with the fire (for example, when a person’s clothes catch fire while cooking), too old or young, or
physically or mentally impaired such that they cannot escape even when warned early enough that escape
should be possible. For these people, additional strategies such as protection-in-place or assisted escape or rescue
are necessary.
•For maximum detection of the various types of fires that can occur within the home, including fast flaming, slow
smoldering, and polyurethane foam, it is recommended that multi criteria smoke alarms be installed. This model
meets the new polyurethane foam fire detection requirements, while at the same time includes intelligent tech-
nology to reduce nuisance alarms from cooking..
•A battery powered alarm must have a battery of the specified type, in good condition and installed properly (this
model has a replaceable 9V battery).
•Smoke alarms must be tested regularly to make sure the battery and the alarm circuits are in good operating
condition.
•Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, within walls, on roofs, on the other side of a closed door or other obstruction.
•If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
•The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For maximum protection, a
smoke alarm should be installed in each sleeping area on every level of a home.
This alarm is not intended to alert hearing impaired individuals.

WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•IMPORTANT: This alarm is designed to detect carbon monoxide gas from ANY source of combustion. It is
NOT designed to detect any other gas.
CAUTION: This alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon
monoxide gas may be present in other areas. Never restart the source of a CO problem until it has been
fixed. NEVER IGNORE THE ALARM!
WARNING: 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. IT
IS NOT SUITABLE FOR INSTALLATION IN HAZARDOUS LOCATIONS AS DEFINED IN THE NATION
AL ELECTRIC CODE. IT IS NOT DESIGNED FOR USE IN A RECREATIONAL VEHICLE RV OR BOAT.
•The installation of this device should not be used as a substitute for proper installation, use, and mainte-
nance of fuel burning appliances, including appropriate ventilation and exhaust systems.
•This alarm does not prevent CO from occurring, nor can it solve any existing CO problem.
WARNING: THIS DEVICE IS DESIGNED TO PROTECT INDIVIDUALS FROM ACUTE EFFECTS OF
CARBON MONOXIDE EXPOSURE. IT MAY NOT FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC
MEDICAL CONDITIONS. IF IN DOUBT, CONSULT A MEDICAL PRACTITIONER. INDIVIDUALS WITH
MEDICAL PROBLEMS MAY CONSIDER USING WARNING DEVICES WHICH PROVIDE AUDIBLE AND
VISUAL SIGNALS FOR CARBON MONOXIDE CONCENTRATIONS UNDER 30 PPM.
•This alarm has not been investigated for carbon monoxide detection below 70 PPM.
•This combination smoke and carbon monoxide alarm requires a continuous supply of electrical power – it
will not work without power.
