 WARNING

Actuation of your CO alarm indicates the 
presence of carbon monoxide (CO), which 
can KILL YOU.

1. Keep calm and open all doors and windows to 

increase the rate of ventilation.

2. Stop using all fuel-burning appliances and 

ensure, if possible, that they are turned off.

3. Evacuate the premises if the carbon 

monoxide alarm continues to sound.

4. Contact your emergency services.

5. Get medical help for anyone suffering the 

effects of carbon monoxide poisoning.

6. Call the appropriate appliance servicing 

and/or maintenance agency so that the 
source of the CO emissions can be identified 
and corrected. Do not use the fuel-burning 
appliances again until they have been 
checked and cleared for use by a competent 
person, according to national regulations.

THE FOLLOWING CONDITIONS CAN RESULT IN 
TRANSIENT CO SITUATIONS

1. Excessive spillage or reverse venting of fuel-

burning appliances caused by:

I) Outdoor ambient conditions such as wind 

direction and/or velocity, including high 
gusts of wind; heavy air in the vent pipes 
(cold/humid air with extended periods 
between cycles).

  II) Negative pressure differential resulting 

from the use of exhaust fans.

  III) Simultaneous operation of several fuel-

burning appliances competing for limited 
internal air.

  IV) Vent pipe connection vibrating loose from 

clothes dryers, boilers or water heaters.

  V) Obstructions in, or unconventional vent pipe 

designs, which amplify the situations above.

2. Extended operation of unvented fuel-burning 

devices (range, oven, fireplace, etc.). 

3. Temperature inversions that can trap exhaust 

gases near the ground.

4. Car idling in an open or closed attached 

garage, or near a home.

5. NEVER bring a charcoal barbecue inside, and 

ALWAYS operate a portable generator outside, 
a safe distance from the house, and well away 
from windows.

 WARNING

The following substances in high 
concentration can affect the carbon 
monoxide sensor and may affect the 
reliability of the alarm or cause false 
alarms: paint, thinners, solvents, 
adhesives, hair sprays, some cleaning 
agents, ammonia, acetone, hydrogen 
methane, iso-butane, iso-propanol, 
ethylene, benzene, toluene, ethyl acetate, 
alcohol-based products, volatile oils, 
silicone vapour, hydrogen sulphide, 
sulphuric acid, hair-grooming products, 
high concentrations of dust and oil mist, 
soaking or splashing with water.
