CO Technology Limitations:

The CO5-SS utilizes an electrochemical CO sensing element, and there-

fore has certain performance limitations. The CO sensing element has a

typical life of 6 years from the date of manufacture, and while the prod-

uct has a timer to create a trouble condition after 6 years of operating,

the date code of the product, rather than the timer, should determine

when the product is replaced. The CO sensing element has a carbon ﬁ l-

ter that provides resistance to false alarms caused by cross-interference

gasses, but the ﬁ lter can be saturated, and so the product should not

be installed in locations where high concentrations of these gasses are

present. Cross-interference gasses include, but are not limited to: Meth-

ane, Butane, Heptane, Ethyl Acetate, Isopropyl Alcohol, Carbon Dioxide,

Ammonia, Ethanol, Toluene, Trichloroethane, and Acetone. Only a cloth

moistened with water should be used to clean the CO5-SS housing.

The movement of gases into the sensing element can be impaired if a

sealant blocks the porous surface of the CO sensor. The CO5-SS should

not be exposed to aerosol products such as furniture polish, paint or

varnish that can coat the CO sensing element and render it inoperative.
