General Maintenance
Storing the unit in a plastic bag during any of the above proj-
ects will protect the sensors from damage. Do not place near a
diaper pail.
WARNING: Reinstall the Smoke/CO Alarm as soon as possible
to assure continuous protection.
When household cleaning supplies or similar contaminates are
used, the area must be well ventilated. The following sub-
stances can effect the CO sensor and may cause false readings
and damage to the sensor:
Methane, propane, iso-butane, iso-propanol, ethyl acetate,
hydrogen sulfide, sulfide dioxides, alcohol based products,
paints, thinner, solvents, adhesives, hair spray, after shave, per-
fume, and some cleaning agents.
Carbon Monoxide Safety Information
General CO Information
Carbon monoxide (CO) is a colorless, odorless, and tasteless
poison gas that can be fatal when inhaled. CO inhibits the
blood’s capacity to carry oxygen.
Possible Sources
CO can be produced when burning any fossil fuel: gasoline,
propane, natural gas, oil and wood. It can be produced by any
fuel-burning appliance that is malfunctioning, improperly
installed, or not ventilated correctly. Possible sources include fur-
naces, gas ranges/stoves, gas clothes dryers, water heaters,
portable fuel burning space heaters, fireplaces, wood-burning
stoves and certain swimming pool heaters. Blocked chimneys or
flues, back drafting and changes in air pressure, corroded or dis-
connected vent pipes, and a loose or cracked furnace exchanger
can also cause CO. Vehicles and other combustion engines run-
ning in an attached garage and using a charcoal/gas grill or
hibachi in an enclosed area are all possible sources of CO.
The following conditions can result in transient CO situations:
Excessive spillage or reverse venting of fuel-burning appliances
caused by outdoor ambient conditions such as: Wind direction
and/or velocity, including high gusts of wind, heavy air in the
