WHAT IS CARBON MONOXIDE

Carbon Monoxide (CO) is an insidious poison that is released when fuels are burnt. It is a colorless, odorless, tasteless gas and therefore very difficult to detect with the human senses. CO kills hundreds of people  each year and injures many more. It binds to the hemoglobin in the bloodand reduces the amount of oxygen being circulated in the body. In high concentrations, CO can kill in minutes. CO is produced by the incomplete combustion of fuels such as wood, charcoal, coal, heating oil, paraffin, petrol, natural gas, propane, butane etc.

Examples of CO sources:

• Running engine in garage -Gas appliances;
• Oil and Gas furnaces -Portable generators;
• Wood stoves -Gas or kerosene heaters;
• Barbecues Clogged chimneys;
• Wood and gas fireplaces Heating boiler.

SYMPTOMS OF CO POISONING
The following symptoms may be related to CO poisoning:

35 ppm| The maximum allowable concentration for continuous exposure for healthy adults in any 8 hour period.
---|---
200 ppm| Slight headaches, fatigue, dizziness, nausea after 2-3 hours.
400 ppm| Frontal headaches within 1-2 hours, life threatening after 3 hours.
800 ppm| Dizziness, nausea and convulsions within 45 minutes. Unconsciousness within 2 hours, Death within 3 hours.
1600 ppm| Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
6400 ppm| Headache, dizziness and nausea within 1-2 minutes.

WARNING: The apparatus may not prevent the chronic effects of carbon monoxide exposure, and that the apparatus will not fully safeguard individuals at special risk. It may not fully safeguard individuals with specific medical conditions. If in doubt, consult a medical practitioner.

LOCATING THE CO ALARM
C11-L Carbon Monoxide alarm is designed to detect the toxic CO fumes that result from incomplete combustion, such as those emitted from appliances, furnaces, fireplace and auto exhaust.
NOTE: For maximum protection an alarm should be fitted in or near every room that contains a fuel-burning appliance such as any gas fires, central heating boilers, room heaters, water heaters, cookers, grills, etc.  WARNING: This alarm will only indicate the presence of carbonmonoxide gas at the sensor. Carbon monoxide gas may be present in other areas.

A CARBON MONOXIDE ALARM DOES NOT FUNCTION AS A REPLACEMENT FOR A SMOKE OR GAS DETECTOR.

LOCATION OF THE CARBON MONOXIDE DETECTOR
General
The design and layout of domestic premises and the number, type and position of carbon monoxide sources vary widely. However, general guidance is given on where and where not to locate the apparatus in order to minimize the risk of misleading indications.

Which room?
Ideally, an apparatus should be installed in every room containing a fule
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 However,if there is a fuel burning appliance in more than one room an the number of apparatus is limited, the following points should be consideredwhen 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 bue near to where the person sleeps.  If the appliance is in a room not normally used (for example a boilerroom), the apparatus should be put just outside the room so that the  alarm may be heard more easily. Alternatively, a remote alarm siren maybe connected to a type A apparatus located in a room(s) containing a fuel-burning appliance.

Where in the room?
It should be possible to view all the light indicators when in the vicinity of the chosen location for the apparatus. It is not possible to give specific guidance on the exact location of a detector which suits all types of room and their usage. The following points should be taken into consideration when determining an optimum location for any appropriate situation:

Where not to install the apparatus
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 ℃ or exceed 40 ℃ , unless it is designed to do so;
• Where dirt an dust may block the sensor;
• In a damp or humid location;
• In the immediate vicinity of the cooking appliance. Apparatus located in the same room as a fuel-burning appliance If the apparatus is located on a wall:
• It should be located close to the ceiling;
• It should be located at a height greater than the height of any door or window.
• A ceiling mounted apparatus should be at least 300 mm from any wall, and for a wall mounted apparatus it should be at least 150 mm from the ceiling.
• The apparatus should be at a horizontal distance of between 1m and 3m from the potential source.
• Id 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.

WARNING: This carbon monoxide alarm is designed for indoor use only. Do not expose to rain or moisture. It will not protect against the risk of carbon monoxide poisoning when the battery has drained. Do not open or tamper with the alarm as this could cause malfunction.
INSTALLING THE CO ALARM
