Carbon Monoxide Alarm: What To Do When the Alarm Sounds
The carbon monoxide (CO) alarm pattern is four quick beeps repeating every 5 seconds. The red LED blinks in sync with the beep pattern. The digital display on model K7DCO will show the PPM level of CO detected.
WARNING: CARBON MONOXIDE ALARM ACTIVATION INDICATES THE PRESENCE OF CARBON MONOXIDE O AT HIGH CONCENTRATIONS WHICH CAN KILL YOU.
Based on recommendations from EN 50292, follow these steps if the alarm sounds:

1. Keep calm and open all doors and windows. Turn off all fuel-burning appliances if possible.
   Note: it is possible that outdoor conditions could influence domestic CO alarms (bad traffic pollution in cold weather, for example). In these circumstances, the level of indoor CO might actually increase when doors and windows are opened.

2. If the alarm continues to sound, even after being reset (where appropriate), then evacuate the premises, alerting other occupants to the risk. Leave doors and windows open. Do not re-enter the premises.

3. Get medical help for anyone suffering the effects of CO poisoning, and advise that CO inhalation is suspected.

4. Call Gas Emergency Services: 0800 111 999, or your local Gas Safe Registered Engineer:

PHONE NUMBER:
Never restart the source of the CO problem until it has been corrected.

Recommended Locations for CO Alarms
NOTE: CO alarms should be installed following the guidance of relevant local standards, such as EN 50292.

• Whether the alarm is wall-mounted or ceiling-mounted, place the alarm at a horizontal distance of between 1 meter and 3 meters from a fuel-burning appliance.

• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a minimum of 150 mm below the ceiling. The bottom of the alarm should also be at a level greater than the height of any door or window.

• Locate within hearing distance of bedrooms* and place at sleeping height if a heating appliance is in the bedroom.

• CO alarms in rooms with sloped ceilings should be located on the high side of the room.

• Ceiling-mounted alarms should be at least 300 mm from any wall.

• If there is a partition in the room, locate the alarm on the same side of the partition as the potential source.

• A CO alarm should be installed in all rooms containing a fuel-burning appliance. Additional CO alarms should be installed in rooms where most awake time is spent, in every sleeping area, and on every level of the home.

Locations to Avoid

• In the garage. Products of combustion are present when you start your motor vehicle.

• Do not install alarms adjacent to, or directly above, heaters or air-conditioning vents.

• In very humid areas (above 90% RH, non-condensing), such as bathrooms and shower rooms. Directly above a sink, or near dishwashers or washing machines. Moisture or steam can cause alarms.

• Do not install within 1 m of heating or cooking appliances, measured horizontally.

• In an area where the temperature may fall below -10 º C or rise above 45 º C such as garage analytics.

• Do not install alarms in dusty areas. Dust particles may cause nuisance alarms or failure to alarm
  In insect-infested areas.

• Within 300 mm of a light fitting, as electronic “noise” generated by the electronics may cause alarms.

• Do not install in an enclosed space (cupboard) or where the ventilation openings in the unit are impeded by items such as newspapers, tablecloths, furniture, curtains, etc.

• Do not install next to a door, window, extractor fan, flue, chimney, or any other area where high may occur or the unit may be directly exposed to the weather.

• Do not install in locations that are difficult or dangerous to reach for testing or maintenance.

Additional Instructions for Caravans and Boats

It is not always possible to find an optimum location for an apparatus, for example, a small caravan or boat may not have suitable vertical surfaces available. Nevertheless, when  sitting an apparatus in such situations, the most important considerations when selecting an appropriate location are:

• Avoid mounting the apparatus directly above a source of heat or steam
• Mount the apparatus at a distance of 1 m to 3 m from the nearest edge of the potential source.
• Avoid running the engine when moored alongside objects such as a wharf, a wall, or another boat
• Avoid running your engine when docked in a crowded marina as vehicle and exhaust fumes can damage the alarm sensor. For further information visit: www.boatsafetyscheme.com

General Carbon Monoxide (CO) Information
What is Carbon Monoxide?
Carbon monoxide (CO) is a highly poisonous gas with no taste, color or smell.

Potential Sources of CO
• Wood-burning stoves
• Gas boilers and fires
• Gas Hobs
• Oil and coal burning appliances
• Portable gas heaters
• Blocked flues and chimneys
• Fumes from integral garages
• Barbecues
• High concentrations of tobacco smoke| This CO alarm is not a substitute for proper installation, use, and maintenance of fuel-burning appliances including appropriate ventilation and exhaust systems. Carbon monoxide can be produced from poorly burning appliances or from blocked flues and chimneys. If our alarm has sounded and you have entilated the room, the CO may have dispersed before help arrives. It is crucial that the source of O is determined and appropriate maintenance carried out.
---|---

Carbon monoxide is a cumulative poison. Long-term exposure to low levels may cause symptoms. This alarm is time-weighted – the higher the level of CO, the sooner it will alarm.
NOTE: The apparatus may respond to brief exhaust gas emissions, for example during the initial start-up of an appliance. Also, hydrogen acts as an interferent and can arise from some battery charging activities and the curing of concrete or cement under certain circumstances. Volatile Organic Compounds (VOCs), e.g. alcohols,  which may eventually activate the alarm, can be generated from the use of damp-proofing materials or other coatings containing alkyl alkoxysilanes.
The table below shows the effects of different levels of CO poisoning on the body;

Risk to life after over 3 hours of exposure
800| Severe headaches, convulsions, vital organ failures. Death possible within 2 – 3 hours

**Warning: The device cannot warn against the chronic effects of exposure to carbon monoxide or protect individuals who are at specific risk.
NOTE: If you recognize any of the above symptoms consult your Doctor immediately.
NOTE: Young children, the elderly and pets are more susceptible to the dangers of CO.
NOTE: Your Kidde alarm is designed to detect CO gas. It is not designed to detect other gas such as natural gas.
NOTE: This product is intended for use in ordinary family homes. It is not designed to measure compliance with occupational safety and the HSE.
NOTE: Individuals with certain specific medical conditions may need an alarm that operates below 30ppm. If this applies consult your Doctor.
IMPORTANT: Ensure that all family members are familiar with the symptoms of CO poisoning and how your alarm works.
To be safe, know the possible sources of CO in your home, caravan, motor home, or boat. Keep fuel-burning appliances and their chimneys and vents in good working condition. Learn the early symptoms of exposure, and if you suspect CO poisoning, move outside to fresh air and get emergency help. Your first line of defense is an annual inspection and regular maintenance of your appliances. Contact a licensed contractor or call your local utility company for assistance.
In rented properties, your Landlord (or Council/ Housing Association), will have an Emergency Response phone number, and be liable for the regular maintenance of their combustion appliances(Gas/LPG/Oil/ Solid Fuel).
Further Information for Caravan and Boat Owners**
The following can lead to carbon monoxide being produced:

• Using LPG cooking appliances for space heating
• Leaving LPG appliances on overnight
• Barbecues within the boat cabin or near a caravan door (e.g. under an awning)

Cleaning Your Alarm

Your Alarm Should be Cleaned at Least Once a Year
You can clean the interior of your alarm by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. Use only water to dampen the cloth, use of detergents or cleaners could damage the alarm. If the alarm is in Fault mode, the alarm may be in need of cleaning. After cleaning, press the test button. If the fault does not clear, the alarm needs to be replaced.

• Never use detergent or other solvents to clean the unit.
• Avoid spraying air freshener, hair spray, or other aerosols near the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect CO.
• Keep away from nappy buckets.
• Never attempt to disassemble the unit to clean inside.  Altering the alarm in any way may lead to a risk of electric shock or prevent it from functioning correctly.  This action will void your warranty.
• The following substances can affect the CO sensor and may cause false readings and damage to the sensor: Methane, propane, isobutane, isopropanol, ethyl acetate, hydrogen sulfide, sulfide dioxides, alcohol-based products, paints, thinners, solvents, adhesives, hair spray, aftershave, perfume, and some cleaning agents.

NOTE: there could be other compounds occurring within a particular household that could cause similar effects. Move the Alarm and place in another location prior to performing any of the following:

• Staining or stripping wood floors or furniture  Painting Wall paperingUsing adhesives

** Storing the unit in a plastic bag during any of the above projects will protect the sensors from damage. When household cleaning supplies or similar contaminates are used, the area must be well ventilated.
WARNING:** REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS DETECTION.
