1. What is Carbon Monoxide?
Carbon monoxide (CO) is a highly poisonous gas with no taste, colour or smell.
Potenal Sources of CO
•Wood-burning stoves
•Gas boilers and res
•Gas Hobs
•Oil and coal burning appliances
•Portable gas heaters
•Blocked flues and chimneys
•Fumes from integral garages
•Barbecues
•High concentraons of tobacco smoke
This CO alarm is not a substute for the correct maintenance of your
appliances.
Carbon monoxide can be produced from poorly burning appliances
or from blocked flues and chimneys.
If your alarm has sounded and you have venlated 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 cumulave poison. Longterm exposure to low levels may cause symptoms.
This Kidde alarm is me-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 inial
start-up of an appliance. Also, hydrogen acts as an interferent and can arise from some baery
charging acvies and the curing of concrete or cement under certain circumstances. Volale
Organic Compounds (VOCs), e.g. alcohols, which may eventually acvate the alarm, can be
generated from use of damp-proofing materials or other coangs containing alkylalkoxysilanes.

2. Further informaon for Caravan and Boat Owners
The following can lead to carbon monoxide being produced:
• Using LPG cooking appliances for space heang
• Leaving LPG appliances on overnight
• Barbecues within the boat cabin or near a caravan door (e.g. under an awning)
To be safe, know the possible sources of CO in your home. Keep fuel burning appliances,
chimneys and vents in good working condion. Learn the early symptoms of exposure, and if
you suspect CO poisoning, move outside into fresh air and get emergency help. Your first line of
defence is an annual inspecon and regular maintenance of your appliances. Contact a licensed
contractor or call your local ulity company for assistance.

2. Important Safety Informaon
If you recognise any of the above symptoms consult your Doctor immediately.
Young children, elderly and pets are more suscepble to the dangers of CO.
Your Kidde alarm is designed to detect CO gas. It is not designed to detect smoke, re
or other gas such as natural gas.
This product is intended for use in ordinary family homes. It is not designed to meas-
ure compliance with occupaonal safety and the HSE.
Individuals with certain speci c medical condions 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.

3. Switching on Your CO Alarm
NOTE: Your CO alarm must be installed by a competent person using the guidance that follows:
1. Remove the baeries from the pack and insert them into the baery compartment. Make
sure that you fit the baeries correctly to the polarity markings (+ or -) shown within the
baery compartment. If correctly installed, the alarm will give a short beep.
2. To test the alarm, press the test buon. The alarm will beep once followed by 4 loud
pulses, then a brief pause and then 4 more pulses, ending with a single beep.
3. If you have a digital read-out alarm (model 7DCO) the LCD screen will show “---“ and then
“888” before seling at “0”
4. Check that the green LED flashes at 30 second intervals to show that the alarm has power.
This is easiest to see in a dark area, or with lights switched off.

4. Installaon Instrucons – Recommended Locaons
• When wall-mounng place the alarm a horizontal distance of between 1 metre and 3 metres from a fuel
burning appliance.
• Wall-mounted alarms should be close to the ceiling, but at least 150mm away to avoid being in ‘dead-air’ space.
• Locate within hearing distance of bedrooms* and place at sleeping height if a heang 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 paron in the room, locate the alarm on the same side of the paron as the potenal source.
*A CO alarm should be installed in all rooms containing a fuel burning appliance. Addional CO alarms should be in-
stalled in rooms where most awake me is spent, in every sleeping area, and on every level of the home.
Locaons to Avoid
• Avoid locang next to draughts, such as doors, windows, extractor fans, air vents or other
similar venlaon openings.
• Avoid locang close to obstrucons (e.g. behind curtains, shelves or furniture).
• Avoid dusty, dirty or greasy areas, such as garages or workshops
• Avoid humid (bathrooms), cold (< -10 oC) or hot (> 40 oC) or damp areas and keep away from sinks.

8. What to do if Your Alarm Sounds!
Carbon Monoxide Alarm Procedure
WARNING! Acvaon of the alarm indicates the presence of Carbon Monoxide (CO) which can kill you.
Based on recommendaons from EN 50292, follow these steps if alarm sounds (4 loud audible pulses
followed by a pause for 5 seconds):
1. Keep calm and open all doors and windows. Turn off all fuel-burning appliances if possible. Note: it is possible
that outdoor condions could influence domesc CO alarms (bad tra c polluon 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 connues to sound, even aer being reset (where appropriate), then evacuate the premises, alerng
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 inhalaon 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 unl it has been corrected. Never ignore the sound
of the alarm! If the alarm is sounding, pressing the test/reset buon will terminate the alarm.
If the CO condion that caused the alert in the first place connues, the alarm will reacvate.
If the unit alarms again within six minutes, it is sensing high levels of CO which can quickly
become a dangerous situaon.
