Alarm/Danger Levels

Caution: This CO alarm will only indicate the presence of CO at the sensor. CO may be present in other areas.

Mild Exposure: Headaches, running nose, sore eyes, often described as “flu-like” symptoms.

Medium Exposure: Dizziness, drowsiness, vomiting.

Extreme Exposure: Unconsciousness, brain damage, death.

Familiarization with the effects of each level is important. The symptoms described in the chart above are related to car- bon monoxide poisoning and should be discussed with ALL members of the household.

Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and disabilities.

Many victims of carbon monoxide poisoning indicate that while they were aware that they were ill, they became so dis- oriented and confused that they were unable to help them- selves by exiting the building or calling for assistance. If you experience any symptoms of carbon monoxide poisoning, con- sult your doctor immediately! CO poisoning can be deter- mined by a simple blood test called a carboxyhemoglobin test. Severe cases may require treatment in a hyperbaric chamber. Remember, young children and household pets may be the first effected.

WARNING: The chart above relates to healthy adults. Levels dif- fer for those at high risk. This product is intended for use in ordinary indoor residential areas. It is not designed to measure compliance with commercial and industrial standards.

This device is designed to protect individuals from acute effects of carbon monoxide exposure. It will not fully safeguard indi- viduals with specific medical conditions. If in doubt, consult a medical practitioner. Individuals with medical problems may consider using warning devices, which provide audible and visu- al signals for carbon monoxide concentrations under 30 ppm.

This CO alarm meets these alarm response times

At 70 PPM, the unit must alarm within 60-240 minutes At 150 PPM, the unit must alarm within 10-50 minutes At 400 PPM, the unit must alarm within 4-15 minutes
