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 K7DCO will show the PPM level of CO detected.
WARNING: CARBON MONOXIDE ALARM ACTIVATION INDICATES THE PRESENCE OF CARBON
MONOXI O AT HIGH CONCENTRATIONS WHICH CAN KILL YOU.
Based on recommendations from EN 50292, follow these steps if 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.
Never ignore the sound of the alarm!
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

10
6. Recommended Locations for CO Alarms
NOTE: 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.

11
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 ºC or rise above 45 º 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.

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 fitting 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
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
PRODUCT TO RAIN OR MOISTURE.

PROPER OPERATION OF THIS ALARM AND WILL PREVENT ITS RESPONSE TO HAZARDS.

14
9. Operation and Testing
Operation
The alarm is operating once it is activated and testing is complete (see “TESTING” below). 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 work-
ing. 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 will allow 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.

12. General Carbon Monoxide (CO) Information
What is Carbon Monoxide?
Carbon monoxide (CO) is a highly poisonous gas with no taste, colour or smell.
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.
Potential Sources of CO 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.

18
The table below shows the effects of different levels 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 recognise 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, 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 defence 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).

13. 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 sen-
sor: 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 contaminates are used, the area must be well ventilated.
WARNING: REINSTALL THE ALARM AS SOON AS POSSIBLE TO ENSURE CONTINUOUS
DETECTION.
