Angers of Carbon Monoxide

Exposure to Carbon Monoxide (CO) is very dangerous. CO is a colourless, odourless and tasteless gas that deprives oxygen from the area. This can be fatal. CO is generated by combustion of carbonaceous materials, mainly when not enough oxygen is available. This can occur for example by malfunctioning or misuse

of appliances used for heating and cooking or by vehicle engines, blocked chimneys, fireplaces, boilers, stoves and any other fuel burning appliance within a confined area.

CO is a toxin that is bound in blood where it prevents the transport of oxygen, which can cause death by suffocation.

Everyone is susceptible but experts agree that unborn babies, pregnant women, senior citizens and people with heart or respiratory problems are especially vulnerable to the dangers of CO.

Combustion appliances should always be installed by a qualified professional. Initial carbon monoxide poisoning symptoms are similar to the flu with no fever and can include:

• dizziness
• severe headaches
• nausea
  vomiting
  disorientation

If symptoms of CO poisoning are experienced, seek medical attention immediately, CO poisoning can be determined by a carboxyhaemoglobin test.

The following symptoms are related to CO poisoning and should be discussed with all members of the household:

1. Mild exposure: slight headache, nausea, vomiting, fatigue (often described as flu-like symptoms).
2. Medium exposure: severe throbbing headache, drowsiness, confusion, fast heat rate.
3. Extreme exposure: unconsciousness, convulsions, cardiorespiratory failure, death.

The product will not trigger an alarm for other hazards such as gas leaks, fires or explosions. A CO detector is no substitute for smoke, fire, heat or other gas detectors.

The product is intended for use in household

environments for typical housekeeping functions. It is not suitable for commercial or industrial applications or for use on recreational or commercial vehicles.

installation of the product should not be used as a substitute for proper installation, use and maintenance of fuel fired facilities, including appropriate ventilation and exhaust systems.
This detector is intended to protect persons from the acute effects of CO.
This detector can not provide people with special medical properties complete security. If in doubt you should consult a physician.
A appliances/equipment should be installed by trained personnel only. Keep the devices/equipment in good mechanical condition and have them checked regularly

The danger of CO levels:

Concentration of CO in air. (ppm = parts per million)	Symptoms
50ppm The maximum allowable concentration for healthy adults to be exposed to in a 8-hour period.
200ppm Within 2-3 hours of exposure: -slight headache -fatigue -dizziness -nausea
400ppm Within 1-2 hours of exposure: -frontal headaches WARNING: 3 hours of exposure will result in death.
800 – 999 ppm Within 45 minutes of exposure: -dizziness -nausea -convulsions -unconsciousness WARNING: 2-3 hours of exposure will result in death.

product is designed to protect users against the acute effects of CO poisoning. The product does not ensure complete protection for people with medical issues.

Installing the batteries (image B)

1. Turn the alarm A 5 counter clockwise to remove it from the bracket A6
2. Insert the batteries into the battery compartment. Make sure that the battery polarity (+/-) matches the polarity markings inside the battery compartment.
3. Turn 5 clockwise to attach it to A 6

Constant exposure to high or low humidity may reduce battery life.

Mounting the product (image C + D )

1. Turn 5 counterclockwise to remove it from A6
2. Place 6 in the desired location.

Follow steps 3-5 for stone/concrete surfaces. Continue to step 6 for wood surfaces.

1. Use 6 to mark the drill locations with a pencil.
2. Drill two 05mm holes.
3. Insert the plugs A 10 into the holes.
4. Fasten the mounting bracket with the screws A 9.
5. Turn 5 clockwise to attach it to A6.

Make sure the arrow on the bracket is pointing upwards when installing to the wall.

Keep the product in a dust free area when drilling. Do not overtighten the screws, this will deform the bracket.

Choosing a location (image E + F )

For safe use, it is recommended to install the product in the following locations:

• Every sleeping area.
• Both ends of a hallway longer than 12 m .
• Every room where multiple people spend several consecutive hours.
• Install at least one product on each floor of a multi-level home.
• Every room where a furnace, a heat source and/or other burning devices are located.
• If there is a basement in the house: At the top of the basement stairs.

The product only indicates the presence of CO near the sensor. CO may be present in other areas.

In areas with a source of combustion

In areas without a source of combustion

In sleeping areas:

• On breathing level.
• Not in turbulent air (near windows, ceiling fans or air conditioners).
• Not behind objects (curtains or closets).

Other areas:

• On breathing level. Depending on the activities in the room the product should be installed on sitting or standing height.
• Not in turbulent air (near windows, ceiling fans or air conditioners).
• Not behind objects (curtains or closets).

Do not install the product:

• in dirty, greasy or dusty areas.
• in temperatures below -10^ .

• in turbulent air (near ceiling fans, air conditioners or open windows).
  within 3 meters of a high humidity source.
  within 1.5 meters of kitchen appliances.
• within 1.5 meters of a furnace or fuel burning heat sources. The optimal distance is 6 meters.
• behind objects like curtains or closets.
• in direct sunlight.

Always remove the product from the area when the following maintenance is performed to prevent damage to the product:

scouring or stripping wooden floors.
painting.
- wallpapering.
using adhesives or aerosols.

The following substances and gasses can cause false

alarms or permanently damage the detector: methane, propane, iso-butane, ethylene, ethanol, alcohol, isopropanol, benzene, toluene, ethylacetate, acid, ether, hydrogen, hydrogen sulphate, hepatic gas, sulphur dioxide, aerosol, propellant, alcohol preparation, paint, thinner, dissolvent, bonding agents, shampoo, aftershave balm, perfume and certain cleaning agents.
