Carbon Monoxide and How It Can
Affect You and Your Family
Carbon monoxide is a dangerous, poisonous gas that kills hundreds of people each year and injures many
more. It is often referred to as the silent killer because it has no odour or taste and cannot be seen. Like
oxygen, CO enters the body through the lungs during the normal breathing process. It competes with
oxygen by replacing it in the red blood cells, thereby reducing the flow of oxygen to the heart, brain and
other vital organs. In high concentrations, CO can kill in minutes.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they
are not feeling well, they become disorientated and unable to save themselves by either exiting the building
or calling for assistance. Exposure during sleep is particularly dangerous because the victim usually does not
wake up.
Symptoms of C poisoning
The following symptoms may be related to CO 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.

35ppm - The maximum allowable concentration for continuous exposure for healthy adults in any 8
hour period, as recommended by the Occupational Safety and ealth Administration
(OS A).
200ppm - Slight headache, fatigue, dizziness, nausea after 2-3 hours.
400ppm - Frontal headaches within 1-2 hours, life threatening after 3 hours.
800ppm - Dizziness, nausea and convulsions within 45 minutes. Unconsciousness within
2 hours. Death within 2-3 hours.
Should you suspect CO may be affecting you or your family, open the doors and windows of your
residence to ventilate, turn off your appliances and evacuate the premises. At this time the authorities
should be contacted to locate the source of the carbon monoxide before re-entering the building. Medical
attention should be sought for anyone suffering the effects of CO poisoning (headache, nausea, see page
3).
Common Sources of C
• Oil and gas furnaces • Wood stoves
• Barbecues • Wood or gas fireplaces
• Gas appliances • Portable generators
• Gas or kerosene heaters • Clogged chimneys
• Cigarette smoke • Any fossil fuel burning appliance

WARNING: This FireAngel carbon monoxide detector is not a combustible gas detector, nor a smoke
detector. Please install the proper detectors to detect combustible gases, or smoke.This CO detector
should not be seen as a substitute for the proper servicing of fuel-burning appliances, nor the sweeping of
chimneys.
WARNING: Do not use this carbon monoxide detector on an intermittent basis, or as a portable
detector for trying to trace one source of the spillage of combustion products from fuel-burning
appliances or from chimneys.

Where To Install Your Detector
WARNING: This detector will only indicate the presence of carbon monoxide gas at the sensor. Carbon
monoxide gas may be present in other areas.
In which room should the detector be installed?
Ideally, an apparatus should be installed in every room containing a fuel burning appliance. Additional
apparatus may be installed to ensure that adequate warning is given for occupants in other rooms, by
locating apparatus in:
• remote rooms in which the occupant(s) spend considerable time whilst awake and from which they may
not be able hear an alarm from apparatus in another part of the premises, and
• every sleeping room.
owever, if there is a fuel burning appliance in more than one room and the number of apparatus is limited,
the following points should be considered when deciding where best to put the apparatus:
• locate the apparatus in a room containing a flueless or open-flued appliance, and
• locate apparatus in a room where the occupant(s) spend most time.
• If the domestic premises is a bedsit (a single room serving as both sitting and bedroom) then the
apparatus should be put as far from the cooking appliances as possible but near to where the person
sleeps.
• If the appliance is in a room not normally used (for example a boiler room), the apparatus should be
put just outside the room so that the alarm may be heard more easily. Alternatively, a remote alarm
siren may be connected to a type A apparatus located in a room(s) containing a fuel-burning appliance.

8
Where in the room should I place the detector?
Apparatus located in the same room as a fuel burning appliance
If the apparatus is located on a wall:
a) it should be located close to the ceiling;
b) it should be located at a height greater than the height of any door or window.
And it should be at least 150mm from the ceiling.
The apparatus should be at a horizontal distance of between 1m and 3m from the potential source.
If there is a partition in a room, the apparatus should be located on the same side of the partition as the
potential source.
Carbon Monoxide alarms in rooms with sloped ceilings should be located at the high side of the room.
Apparatus located in sleeping rooms and in rooms remote from a fuel burning appliance
Apparatus located in sleeping rooms and in rooms remote from the fuel-burning appliance should be
located relatively close to the breathing zone of the occupants.

9
Do not put the detector
The apparatus should not be installed:
In an enclosed space (for example in a cupboard or behind a curtain).
Where it can be obstructed (for example by furniture).
• directly above a sink
• next to a door or window
• next to an extractor fan
• next to an air vent or other similar ventilation openings
• in an area where the temperature may drop below -10°C or exceed 40°C
• where dirt and dust may block the sensor
• in a damp or humid location
• in the immediate vicinity of the cooking appliance

How To Install Your Detector
Note: This carbon monoxide alarm must be installed by a competant person
To install your unit, follow the illustration below.
Your detector should be installed on the wall.
To Mount on the Wall: old the
mounting bracket against the wall and mark
the inside location of each keyhole. Drill a
5mm (3/16”) hole into the wall. Insert the
plastic screw anchors into the mounting
holes. Screw the mounting bracket to the
wall.
Now install the approved 9 volt alkaline
battery required, as provided with your
detector.

Battery Installation/Replacement
See diagrams on page 11
a. If the detector is wall mounted, flip the detector casing down so that the battery compartment is exposed.
b. Remove the battery cover.
c. Replace the battery with an approved 9 volt alkaline battery (see page 24 for a list of approved batteries),
making sure the battery terminals align properly with the terminals on the battery clip and push the
battery into place.
Replace the battery cover and return the detector to the original position.
d. When the battery is connected, your detector will first display all the icons.The digital readout
will then display a ‘0’, the PPM readout will flash, the LED will flash yellow and the detector will
beep to indicate that the battery is properly connected.
e. Your advanced FireAngel detector requires a short ‘warm-up’ period before it is fully operational.
If you have followed all of the above steps correctly, your unit will begin monitoring for CO in
around 3 minutes.The flashing PPM symbol is your assurance that the unit is receiving power.
When the 3 minute warm-up period is complete, the LED will flash green once per minute as an
additional indication that the alarm is receiving power from the battery and is fully operational. If
there are problems with your unit the LED will flash yellow instead of green, a single chirp once
per minute will be emitted and the digital display will flash ‘Err’ to indicate that the alarm has malfunctioned
(see page 21).
f. Test the the horn and battery by pressing the Test/Reset button briefly to confirm that the detector is
operating properly.The detector should sound as soon as the button is pressed, indicating that the horn is
working and the battery is providing power to the unit. Release the Test/Reset button to silence the horn.
The horn and battery should be tested on a weekly basis.
Warning: Prolonged exposure to the horn in close proximity will damage your hearing.
11

Under normal operating conditions, the battery should last for 1 year.
When the unit is in full alarm the battery life is 7 days (from full capacity).The detector will not protect
against the risk of CO poisoning when the battery has drained.
Warning: Constant exposure to extreme high or low temperatures may reduce battery life.

perating Features
Your FireAngel detector offers many features which set it apart from other CO detectors on the market
today.
Test/Reset Button Feature
This button will:
• reset the peak level memory of your alarm (see page 16)
• test your sensor, horn and battery
• silence the loud 85dB horn during an alarm (only for an alarm due to levels below 50ppm)
• when held down, the readout will display the peak level of CO recorded over the last 4 weeks
• resets the peak level memory and alarm icons displayed following an alarm
• allows you to test the sensor by introducing a source of CO into the detector

Digital Display and Action Prompt
Digital Display
FireAngel’s unique digital readout displays the amount of CO in the area of the
sensor, expressed in parts per million (ppm).Your detector is designed to
display levels from 10ppm to 999ppm.
Note: Ambient background levels between 0ppm and 10ppm will register as
0ppm on the display.
14

Testing the Horn and Battery
Test the unit by pressing the Test/Reset button briefly to confirm that the detector is operating properly.
The detector should sound as soon as the button is pressed, indicating that the horn is working and the
battery is providing power to the unit. Release the test/reset button to silence the horn. The horn and
battery should be tested on a weekly basis.
15

Peak Level Reading Feature
The peak level reading is the highest level of CO recorded by the unit over the last four weeks.
To display the peak level reading firstly place your left thumb or finger over the sounder vent (see
diagram), then press and hold the Test/Reset button down with your right thumb or finger.The horn will
sound and the detector will display the peak level reading stored in the memory until you release the
button or for a maximum of 4 seconds.
This feature is helpful to a technician servicing your home or possibly to yourself when returning home
after a period of time and discovering the high or low level icon displayed on the digital display indicating
that the alarm has sounded in your absence.
olding the Test/Reset button down
for 5 seconds will reset the peak
level reading to ‘0’.
Replacing the battery will also cause
the peak level reading to reset to ‘0’.

Testing The Sensor
If testing the sensor for the first time after installation, or replacing a battery, make sure
that the alarm has completed the 3 minute warm up period and the LED is flashing green
once every minute, as carrying out a sensor test before this could give false readings.
CAUTI N: All sensor testing should only be performed by a responsible adult.
This test should only be performed once a month. Excessive testing will cause the battery
life to be shortened.
N TE: C test kits may be used in order to avoid having to burn cigarettes, incense
sticks etc.
We suggest the use of an incense stick or cigarette as the inefficient way in which they
burn gives off a readable localized amount of C . A readable level of carbon monoxide
will not be given off by other sources of smoke, for example an extinguished candle or
match.
Step 1: If the alarm is wall mounted unhook it from the fixing screws.
Step 2: Cover sounder vent with left thumb/finger (see previous diagram on opposite
page). old the Test/Reset button down for around six seconds until the Spray Can Icon is
visible.This indicates that the detector is now monitoring continuously for CO and may be
tested using a known source of CO.
Step 3: Light a cigarette or an incense stick using a match or lighter. Extinguish the lighter, or put out the
match and place it into a dish of water.

18
Step 4: Turn the alarm on its side so that the vents nearest the
Test/Reset button on the side of the alarm are pointing
downwards (see diagram opposite). old the burning cigarette
or incense stick 15-20cm (6-8 inches) below the detector, so
that the smoke moves towards the holes in the sides of the
detector.The display will indicate the amount of CO in the
smoke (it may take up to 2 minutes for a reading to be shown).
An increase in the reading on the digital display will indicate that
the sensor and electronics are working properly.
Note: The alarm will only sound if excessive amounts of CO
are detected during this short test.
Step 5: Put out the cigarette or incense stick by placing it into a
dish of water. Ensure that all flames have been extinguished.
Step 6: The spray can icon will disappear after four minutes, and
the detector will return to normal monitoring mode.
Note: If the spray can icon flashes press the Test/Reset button
once to return to ‘sensor testing’ mode.
