1. Read This First
• Congratulations on becoming the owner of an Elk Carbon Monoxide Alarm. This product
is designed to help protect you and your household from the dangerous effects of Carbon
Monoxide- the silent killer.
• The Carbon Monoxide Alarm (CO Alarm) is powered up by carefully rotating it onto the
mounting plate which activates the on/off switch. The red, amber & green lights will
immediately flash in sequence to show they are working. Please wait 15 seconds after
connecting the power before button testing.
We recommend that you:
• Install a CO Alarm in every room that contains a fuel burning appliance, particularly
rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms.
• In rooms with an appliance, install (preferably) on the ceiling, (300mm from walls) and
between 1.5m to 3m horizontally from appliance. In rooms remote from the appliance
install at ‘head height’, where the light indicators can be seen.
• Test the Alarm weekly by pressing the test/hush button. The horn will sound (at a
diminished sound level initially and then quickly reach maximum sound output level).
• Replace Alarm after approx. 10 years of operation (see ‘Replace by’ date on side wall
label).
• Do not install during building construction so as to avoid contamination.
• Individuals with medical problems may consider warning devices which provide audible
and visual signals for carbon monoxide concentrations under 30ppm.

2. Carbon Monoxide – The Silent Killer
5
2.1 What is Carbon Monoxide?
Many people are killed each year, and many more suffer 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/bottled gas, paraffin, wood, petrol, 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/flues.
• Blocked vents or draught-proofing which makes areas with fuel burning
appliances or fireplaces airtight.
• Engines of cars, lawnmowers etc. left running in confined spaces.
• Portable paraffin or gas heaters in badly ventilated rooms.
2.2 What happens when your CO Alarm detects Carbon Monoxide?
When the Alarm detects potentially dangerous levels of CO, it flashes the red alarm
light immediately and then sounds a loud alarm if the CO persists. Table B below
shows how the CO Alarm reacts to different levels of CO gas and exposure time.
At higher levels of CO, the alarm turns on sooner. The rate of flashing of the red light
indicates the level of CO. If your CO Alarm sounds, follow the instructions on page
and NEVER IGNORE THE ALARM !

150 Slight headache after 1.5 hours.
200 Slight headache, fatigue, dizziness, nausea after 2-3 hours.
400 Frontal headaches within 1-2 hours, life threatening after 3 hours, also maximum
parts per million in flue gas (on an air free basis) according to US Environmental
Protection 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.
6,400 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 “flu” -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.

Pre-Alarm (before horn sounds): When the Alarm detects over 50 ppm CO the
red light flashes in accordance with Table B. This helps locate CO leaks as the unit
gives an indication straight away.
(Without this feature the CO level would need to be at 50 ppm CO for typically
72 minutes for an alarm sound to be given). Note the Pre-Alarm signal may be
triggered by CO coming for example, from cooking with gas, from car engines or
from nearby barbecues. This is usually not a concern, unless the Pre-Alarm signal
persists until the alarm sounds and the CO source is unknown.
NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols
are released nearby.
CO ALARM MEMORY
The CO Alarm memory is an important feature of the CO Alarm 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 light will flash at different 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, thered led will flash in accordance toTable C. Display
models will show the peak level of CO measured.

Reset Memory: Hold down the test button until the red light stops and the green
light starts flashing. Cover the horn with a cloth to muffle the alarm during this time.
Please note that the memory will also be reset when the unit is switched off.
3. Where to Place CO Alarms
NATIONAL FIRE PROTECTION ASSOCIATION REQUIRED PROTECTION
For your information the National Fire Protection Association’s standard 720
advises as follows:
Carbon Monoxide Alarms 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)

10
IMPORTANT!
Specific requirements for Carbon Monoxide Alarm 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 Alarm 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 Alarms to be fitted is limited, the
following points should be considered when deciding where best to fit the Alarm(s)
- If there is an appliance in a room where people sleep, place a CO Alarm in
this room
- Locate a CO Alarm in a room containing a flueless or open-flued appliance, and
- Locate an Alarm in a room where the occupant(s) spend most of their time (e.g.
sitting room)
- In a bedsit, the CO Alarm should be placed as far away from the cooking
appliance as possible, but near to where the person sleeps
- If the appliance is in a room not normally used, such as a boiler room, the CO Alarm
should be placed just outside the room so that the alarm will be heard more easily.

Quick Test with Carbon Monoxide
The Carbon Monoxide Alarm checks for CO gas every 4 seconds and when exposed
to the CO gas, the red light will flash (as per Table B) to confirm that it is detecting the
CO gas.
The Alarm can be tested with carbon monoxide gas by using one of the kits that comes
with the gas either in a glass phial or aerosol can. Follow the instructions on the kit.
If a test gas kit is not readily available, it is also possible to gas test the Alarm using
a joss stick or cigarette smoke. To do this remove the Alarm from its base and slide
