willhelpprotectyouandyourhouseholdfromthedangerouse󰀨ectsofCarbonMonoxide-
the silent killer.
• Remove the battery pulltab to engage the batteries. The Carbon Monoxide Detector is
poweredupbycarefullyrotatingitontothemountingplatewhichactivatestheon/o󰀨switch.
Thered,amber&greenlightswillimmediatelyashinsequencetoshowtheyareworking.
Then wait 15 seconds after connecting the power before button testing.
• Install a CO Detector in every room that contains a fuel burning appliance, particularly high
occupancy areas e.g. bedrooms, kitchens etc.
• In rooms with a fuel burning appliance, install (preferably) on the ceiling, (1ft (300mm)
from walls) and between 5ft to 10ft horizontally from appliance. In rooms remote from the
appliance install at ‘head height’, where the Detector indicators can be seen.
• Test the Detector weekly by pressing the test/hush button, the horn will sound (at a
diminished sound output level initially and then quickly reach maximum sound output level).
• Replace Detector after approx. 10 years operation (see ‘Replace by’ date on side wall
label).
• Do not install Detector until all construction is completed to avoid contamination.
• Individuals with health issues may consider warning devices which provide audible and
visual signals for carbon monoxide concentrations under 30ppm.

2. Carbon Monoxide – The Silent Killer
2.1 What is Carbon Monoxide?
Many people are killed each year, and many more su󰀨er ill health from Carbon Monoxide
(CO) poisoning. CO is an invisible, odorless, tasteless and extremely toxic gas. It is produced
by appliances and vehicles burning fuels, such as coal, oil, natural gas, propane, kerosene,
para󰀩n,wood,gasoline,diesel,charcoaletc.COisabsorbedbyredbloodcellsinthelungs
in preference to oxygen - this results in rapid damage to the heart and brain from oxygen
starvation.
High levels of CO in a house can be caused by:
• Incorrectly or poorly installed fuel-burning appliances.
• Blockedorcrackedchimneys/ues.
• Blocked vents or draft-proong which makes areas with fuel burning appliances or
replacesairtight.
• Enginesofcars,lawnmowersetc.leftrunninginconnedspaces.
• Portable kerosene or propane heaters in poorly ventilated rooms.
2.2 What happens when your CO Detector detects Carbon Monoxide?
WhentheDetectordetectspotentiallydangerouslevelsofCO,itashestheredalarmLED
immediately and then sounds a loud alarm if the CO persists. Table B below shows how the
CODetectorreactstodi󰀨erentlevelsofCOgasandexposuretime.AthigherlevelsofCOthe
alarmturnsonsooner.TherateofashingoftheredLEDindicatesthelevelofCO.IfyourCO
Detector sounds follow the instructions on page 20. NEVER IGNORE THE ALARM!

Agency.
800 Dizziness,nauseaandconvulsionswithin45minutes.Unconsciousnesswithin
2 hours. Death within 2-3 hours.
1,600 Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
3,200 Headache, dizziness and nausea within 5-10 minutes. Death within 25-30 minutes.
3,400 Headache, dizziness and nausea within 1-2 minutes. Death within 10-15 minutes.
12,800 Death within 1-3 minutes.
The following symptoms may be related to CARBON MONOXIDE POISONING and should be discussed
with ALL members of the household:
Mild exposure:Headaches,runningnose,soreeyes,oftendescribedas“u”-likesymptoms;
Medium exposure: Dizziness,drowsiness,vomiting;
Extreme Exposure:Unconsciousness,braindamage,death.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are
not well, they become so disoriented they are unable to save themselves by either exiting the building or
calling for assistance.

CO present (before horn sounds): When the Detector detects over 45 ppm CO
theredLEDashesinaccordancewithTableB.ThishelpslocateCOleaksas
the unit gives an immediate indication.
(Without this feature the CO level would need to be at 45 ppm CO for typically
90minutesforanalarmsoundtobegiven).NotetheredLEDashesmaybe
triggered by CO produced by gas appliances, from car engines or nearby barbe-
cues.Thisisusuallynotaconcern,unlesstheredLEDashespersistuntilthe
Detector sounds and the CO source is unknown.
NOTE: The CO Detector may sound if cigarette smoke is blown into it, or aero-
sols are released nearby.
ALARM MEMORY
The alarm memory is an important feature of the CO Detector where even if the
house is unoccupied during an alarm condition it warns the homeowner that the
unit has previously detected CO gas and been in alarm. The memory feature has
two operation modes:
- memory indication for 24 hour period after alarm.
- memory recall on demand
24 hour memory indicators: Afteralarm,theREDLEDwillashatdi󰀨erent
rates every 50 seconds depending on the level of CO detected - see Table C.
Memory recall on demand: To review the memory status after initial 24 hours,
pressandholdthetestbutton,theredLEDwillashinaccordancetoTableC.

3. Where to Place CO Detectors
NATIONALFIREPROTECTIONASSOCIATIONREQUIREDPROTECTION
For your information the National Fire Protection Association’s Standard 720
advises as follows:
Carbon Monoxide Detectors shall be installed as follows:
1. Outside of each separate dwelling unit sleeping area in the immediate vicinity of
the bedroom.
2. On every occupiable level of a dwelling unit, including basements but excluding
attics and crawl spaces.
3. Other locations where required by applicable laws, codes or standards. The
equipment should be installed using wiring methods in accordance with the
National Fire Protection Association’s Standard 72, 720. (National Fire Protection
Association, Batterymarch Park, Quincy, MA 02269)

IMPORTANT!
SpecicrequirementsforCarbonMonoxideDetectorinstallationvaryfromstateto
state and from region to region. Check with your local Fire Department for current
requirements in your area.
3.1 Ideally a Carbon Monoxide Detector should be installed in:
- Every room containing a fuel burning appliance, and
- Remote rooms where occupants spend a considerable amount of time
- Every bedroom.
HoweverifthenumberofCarbonMonoxideDetectorstobettedislimited,thefollow-
ingpointsshouldbeconsideredwhendecidingwherebesttottheDetector(s)
- If there is an appliance in a room where people sleep, place a CO Detector in
this room
- LocateaCODetectorinaroomcontainingauelessoropen-uedappliance,and
- Locate a CO Detector in a room where the occupant(s) spend most of their time
(e.g. family room)
- In a studio apartment, the CO Detector should be placed as far away from the cook-
ing appliance as possible, but near to where the person sleeps
- If the appliance is in a room not normally used, such as a furnace room, the CO
Detector should be placed immediately outside the room so that the Detector will be
heard more easily.

6. What to do when the alarm sounds
Functional Gas Test
The Carbon Monoxide Detector checks for CO gas every 4
secondsandwhenexposedtotheCOgas,theredLEDwillash
(asperTableB)toconrmthatitisdetectingtheCOgas.
Solo C6 brand canned CO testing agent may be used to verify
the Detector’s ability to sense CO. To gas test the Detector, for 3
secondsspraythe cannedCOwithin1/4”ofthegas entryholes
(seeFigure9).Withinseconds,theredLEDwillbegintoash(as
perTable B)toconrmtheDetector hasdetectedCO.Toenter
the accelerated functional gas test mode, press the Test button
momentarily (approx. 1 second) while the Detector is indicating CO
presence. The Detector will sound 2 x 4 temporal tone patterns to
indicate an alarm condition.
To return the unit to standby, simply leave the Detector in clean air
forafewminutesuntiltheredLEDisnolongerashing. Figure 9
Warning! “Actuation of your CO Detector indicates the presence of carbon
