1. 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 K10LLDCO will show the PPM level of CO detected.

⚠️ WARNING: CARBON MONOXIDE ALARM ACTIVATION INDICATES THE PRESENCE OF CARBON MONOXIDE (CO) 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: Outdoor conditions (e.g., bad traffic pollution in cold weather) can influence domestic CO alarms; indoor CO levels might increase when doors and windows are opened.
2. If the alarm continues to sound, even after being reset (where appropriate), 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.

6. 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 a horizontal distance of between 1 metre and 3 metres 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.

7. 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. Do not install directly above a sink, or near dishwashers or washing machines. Moisture or steam can cause nuisance alarms.
• Do not install within 1 m of heating or cooking appliances, measured horizontally.
• In an area where the temperature may fall below -10°C or rise above 45°C, such as garages and unfinished attics.
• Do not install alarms in dusty areas. Dust particles may cause nuisance alarm or failure to alarm.
• In insect-infested areas.
• Within 300 mm of a light fitting, as electronic "noise" generated by the electronics may cause nuisance alarms.
• Do not install in an enclosed space (cupboard) or where the ventilation openings in the unit could be impeded by items such as newspapers, table-cloths, furniture, curtains, etc.
• Do not install next to a door, window, extractor fan, flue, chimney, or any other area where high air flow may occur or the unit may be directly exposed to weather.
• Do not install in locations that are difficult or dangerous to reach for testing or maintenance.

⚠️ WARNING: FAILURE TO PROPERLY INSTALL AND ACTIVATE THIS ALARM WILL PREVENT PROPER OPERATION OF THIS ALARM AND WILL PREVENT ITS RESPONSE TO HAZARDS.

9. Operation and Testing

Operation

The alarm is operating once it is activated and testing is complete. When CO is detected, the unit sounds a loud alarm. See Section 1 for alarm signal descriptions. In high levels of CO, the unit will go into alarm in a shorter period of time than at low levels of CO.

Testing

Test your alarm weekly, or after returning from a vacation or absence, by pressing and releasing the button quickly. A quick beep will confirm the button has been pushed, followed by the test sequence. See "Other Alarm Visual and Audible Indicators" table. The alarm will sound if the electronic circuitry, horn, and batteries are working. If the alarm does not sound, or gives erratic or low volume sound, the unit must be replaced.

⚠️ WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 1 METRE AWAY FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING.

BUMP TEST MODE

This alarm includes a "bump test" mode that allows the alarm to be qualitatively tested during field service using commercially available aerosol CO.

1. Hold the test button down for 10 seconds.
2. The unit will chirp 3 times, indicating the start of test mode.
3. The Green LED flashes once per second during test mode.
4. Apply the commercially available aerosol CO.
5. CO alarm sounds if CO reading is above 40 ppm.
6. The alarm will automatically exit from the bump test mode after 2 minutes, followed by reset.

Note: The test can be terminated manually by pressing the test button.

Caution: This unit should only be bump tested using clean, dry CO test gas by a trained service engineer.

10. Recognizing Nuisance Alarms

Carbon Monoxide (CO) Nuisance

RESET: Pushing the test / reset button during a CO alarm allows the unit to reset calculations and double-check for the presence of CO. If the unit re-alarms, it is sensing high levels of CO, which can quickly become a dangerous situation. Move to fresh air and call 0800 111 999.

⚠️ WARNING: IT IS IMPOSSIBLE TO DETERMINE THE SOURCE OF A CO ALARM USING SIGHT OR SMELL. ALWAYS CONSIDER A CO ALARM EVENT AS DANGEROUS.

12. Permanently Disable Alarm / Discharge Battery

⚠️ WARNING: FAILURE TO DISCHARGE ALARM BATTERY AS INSTRUCTED PRIOR TO DISPOSAL MAY CREATE POTENTIAL FOR LITHIUM BATTERY RELATED FIRE OR HAZARD.

⚠️ WARNING: DISCHARGING THE ALARM BATTERY IS PERMANENT

• Once the alarm battery has been discharged, it cannot be reactivated!
• Once discharged, the alarm will NO LONGER DETECT CO.
• Once the alarm battery is discharged, the battery is depleted and the alarm will no longer function.
• Once the alarm battery has been discharged, the alarm cannot be mounted onto the mounting bracket or reactivated.

To Permanently Disable Alarm / Discharge Battery:

1. Remove the bracket/back cover from the unit by sliding a screwdriver between the unit and the cover at the recess in the center of the unit. This allows access to the back of the unit.
2. Once the back of the unit is visible, locate the expanded slot on the lower left hand side. Using a flat blade screwdriver, insert it into the slot and slide it toward the top of the unit. You should feel the switch inside the unit slide up and stop. Be sure to insert the screwdriver straight in and not at an angle where the switch might be missed.

13. General Carbon Monoxide (CO) Information

What is Carbon Monoxide?

Carbon monoxide (CO) is a highly poisonous gas with no taste, colour 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 your alarm has sounded and you have ventilated the room, the CO may have dispersed before help arrives. It is crucial that the source of CO 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 use of damp-proofing materials or other coatings containing alkylalkoxysilanes.

Effects of CO Poisoning on the Body

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, 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. 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).

14. 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; the 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, iso-propanol, ethyl acetate, hydrogen sulfide, sulfide dioxides, alcohol based products, paints, thinner, solvents, adhesives, hair spray, aftershave, perfume, and some cleaning agents.
• Note: There could be other compounds occurring within a particular household which 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 papering, Using 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 contaminants are used, the area must be well ventilated.

⚠️ WARNING: REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS DETECTION.
