Mild exposure: Slight headache, nausea, vomiting, fatigue,
runny nose, sore eyes (often described as "flu-like" symptoms).
Medium exposure: Severe throbbing headache, dizziness,
drowsiness, confusion, fast heart rate.
Extreme exposure: Unconsciousness, brain damage,
convulsions, cardiorespiratory failure, death.
Many cases of reported CO poisoning indicate that while
victims are aware they are not well, they become so
disorientated that they are unable to save themselves by either
exiting the building or calling for assistance. Young children
and pets may be the first affected.
CO sources
The CO sensor in this detector is designed to detect carbon
monoxide gas from any source of combustion. It is not
intended to detect fire, smoke, or any other gas. Potential CO
sources include fuel-fired appliances (e.g., space heater,
furnace, water heater, range, oven, clothes dryer); other
sources of combustion (e.g., kerosene-burning stove or heater,
or gas log fireplace); or internal combustion engines.
In addition, excessive exhaust spillage or reverse venting of
fuel-burning appliances can produce dangerous transient
levels of CO. This can be caused by external conditions:
• Wind direction, velocity, or a combination of both,
including high gusts of wind or insufficient draft in vent
pipes
• Temperature inversions that can trap exhaust gases near
the ground
• Negative pressure differential resulting from the use of
exhaust fans
• Simultaneous operation of several fuel-burning appliances
competing for limited internal air
• Vent pipe connections vibrating loose from dryers,
furnaces, or water heaters
• Obstructions in vent pipes or unconventional vent pipe
designs which can amplify the above situations
• Poorly designed or maintained chimneys and/or vents
• Extended operation of unvented fossil fuel-burning devices
(range, oven, fireplace, etc.)
• Idling cars in an open or closed attached garage, or near
the premises
General limitations of CO detectors
This detector is designed to protect individuals from the acute
effects of CO exposure. It will not fully safeguard individuals
with specific medical conditions. People with special medical
problems should consider using specialized detection devices
with less than 30 ppm (parts per million) alarming capabilities.
If in doubt, consult a medical practitioner.
If the unit is in trouble or at the end of its life, it may not sense
CO and cannot be relied upon to monitor CO levels. Replace
the CO detector within ten years from the date of manufacture
or when the detector indicates an end of unit life condition,
whichever comes first.
A detector installed outside a bedroom may not awaken a
sleeper. Normal noise due to stereos, television, etc. may also
prevent the detector from being heard if distance or closed or
partly closed doors muffle the sounder. This unit is not
designed for the hearing impaired.
CO detectors are not a substitute for designated life safety
devices. Though these detectors will warn against increasing
CO levels, we do not warrant or imply in any way that they will
protect lives from CO poisoning. They should only be
considered as an integral part of a comprehensive safety
program.
Detector locations
Selecting a suitable location is critical to the operation of CO
detectors. Figure 1 shows appropriate detector locations.

Description
The 260-CO SafeAir Carbon Monoxide Detector detects
carbon monoxide gas, monitors the levels of CO gas, and
gives early warning when potentially dangerous levels exist. It
includes a built-in sounder that acts as a primary alarm
notification device. (The control panel is the supplementary
alarm notification device.)
The 260-CO SafeAir Carbon Monoxide Detector is a four-wire
device that uses a Class 2 output from a control panel (listed to
the UL 985 or 864 standards), or from an auxiliary power
supply. It is intended for indoor-dwelling unit applications in
both residential and commercial occupancies, including single
and multiple family residential occupancies, hotel rooms, dorm
rooms, and other areas approved by the authority having
jurisdiction (AHJ).
The 260-CO detector meets UL 2075 Standard for Gas and
Vapor Detectors and Sensors. It does not detect fire, smoke, or
any other gases.
Alarms and Signals
The 260-CO detector produces varying sounds in addition to
the alarm signal. It also flashes a multicolored LED to indicate
the detector status. Table 1 lists status indications of the
detector.
