Carbon Monoxide Detector
Figure 1: Detector features
WARNING: This detector should be installed by a
certified technician.
Attention: Please take a few minutes to thoroughly read this
user guide which should be saved for future reference and
passed on to any subsequent owner.
WARNING: Installation of this CO detector is not a
substitute for proper installation, use, and maintenance of fuel
burning appliances including appropriate ventilation and exhaust
systems.
Detector location
CO detectors should be mounted in or near bedrooms and living
areas. We recommend that you install a detector on each level of
your home.
When choosing your installation locations, make sure you can
hear the detector from all sleeping areas. If you install only one
CO detector in your home, install it near bedrooms, not in the
basement or furnace room.
Place the detector out of reach of children. Under no
circumstances should children be allowed to handle the CO
detector.

Description
The 263A-CO-OEM-ATT01 wireless carbon monoxide (CO)
detector monitors the levels of CO gas and gives early warning
when potentially dangerous levels exist. It does not detect fire,
smoke, or any other gas. If a dangerous concentration of CO is
detected by the patented and field-proven electrochemical
sensor, an LED indicator illuminates and an internal siren is
activated in temporal 4 pattern. The CO detector also transmits
an alarm signal to the control panel within 15 seconds of
detecting dangerous concentration of CO gas. The control panel
activates its internal siren and reports the detector condition to
the central monitoring station. The CO detector also detects low
battery, wall tamper, and detector end-of-life. These trouble
codes are transmitted to the control panel. The detector
automatically resets when CO is no longer detected.
The 263A-CO-OEM-ATT01 wireless CO Detector is certified to
the ANSI/UL2075 standard for CO detectors. It is intended for
residential indoor dwelling unit applications. It is not intended for
use in industrial applications.
WARNING: After ten years from initial power up, this
detector will beep two times every 30 seconds to indicate that it
is time to replace the detector. Replace the detector immediately!
It will not detect CO in this condition.
To help identify the date to replace the detector, an area has
been reserved on the side of the detector. Write the “replace by”
date (ten years from power up) with a permanent marker in the
area provided.

Testing
Note: This unit is sealed. The cover is not removable.
WARNING: The control panel must be placed into sensor
test mode while conducting any tests. Placing the control panel
into sensor test mode for all testing helps to protect against false
alarms and unintentional central station reporting.
Due to the loudness of the detector, we suggest that you place
your fingers over the sounder vent while testing your detector.
Caution: Continuous exposure to the high sound level of
this detector over an extended period of time may cause hearing
loss.
The CO detector provides three test modes:
• Normal CO detector test. Conducts an internal self-test
and tests the sounder.
• RF communication test. Tests the communication path
with the control panel.
• CO sensor functional gas test. Tests the functional
operation of the CO sensing element.
RF communication test
This section provides general guidelines for testing the CO
detector with the panel. Refer to the specific panel
documentation for complete testing details.
Before testing, ensure that your control panel is set to sensor
test mode. Setting your panel to sensor test mode prevents an
alarm signal from being transmitted to the central monitoring
station (if you have a monitored system).

Maintenance tips
To keep your detector in good working order:
• Perform a CO detector test once a week (see “Normal CO
detector test” on page 3).
• Vacuum the detector cover once a month to remove
accumulated dust.
• Never use detergents or solvents to clean the detector.
Chemicals can permanently damage or temporarily
contaminate the detector.
• Avoid spraying air fresheners, hair spray, paint, or other
aerosols near the detector.
• Do not paint the detector. Paint will seal the vents and
interfere with proper sensor operation.
Move the CO detector to a remote location, to prevent possible
damage or contamination of the sensor, prior to performing any
of the following:
6 / 8 2533-7222-00
• Staining or stripping floors or furniture, painting or wall-
papering.
• Using aerosols or adhesives.
WARNING: Reinstall the CO detector as soon as possible
to assure continuous protection.
The following is a list of substances that at high levels can
damage the CO sensor or cause temporary readings that are
not CO readings:
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene,
ethyl acetate, hydrogen, hydrogen sulfide, and sulfur dioxide.
Also most aerosol sprays, alcohol-based products, paint,
thinner, solvent, adhesive, hair spray, after shave, perfume,
auto exhaust (cold start), and some cleaning agents.
Page 7
Information about carbon monoxide:
Carbon monoxide is a colorless, odorless, and tasteless poison
gas that can be fatal when inhaled. CO inhibits the blood’s
capacity to carry oxygen.
Periodically review this detector user guide and discuss your
CO Alarm emergency procedure with all members of your
family. Never ignore a CO Alarm. A true alarm is an indication
of potentially dangerous levels of CO. CO detectors are
designed to alert you to the presence of CO before an
emergency - before most people would experience symptoms
of CO poisoning, giving you time to resolve the problem calmly.
Determine if anyone in the household is experiencing
symptoms of CO poisoning. Many cases of reported CO
poisoning indicate that while victims are aware they are not
well, they become so disoriented they are unable to save
themselves either by exiting the building or calling for
assistance. Also, young children and household pets may be
the first affected. You should take extra precautions to protect
high-risk persons from CO exposure because they may
experience ill effects from CO at levels that would not ordinarily
affect a healthy adult.
Symptoms of CO poisoning
The following common symptoms are related to CO poisoning
and should be discussed with ALL members of the household:
• Mild exposure = Slight headache, nausea, vomiting,
fatigue (often described as “flu-like” symptoms).
• Medium exposure = Severe throbbing headache,
drowsiness, confusion, fast heart rate.
• Extreme exposure = Unconsciousness, convulsions,
cardio-respiratory failure, death.
If you experience even mild symptoms of CO poisoning,
consult your doctor immediately.
Conditions that can produce carbon
monoxide
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 vent
pipes (cold/humid air with extended periods between
cycles).
• Negative pressure differential resulting from the use of
exhaust fans.
• Simultaneous operation of several fuel burning appliances
competing for limited internal air.
• Vent pipe connection vibrating loose from clothes dryers,
furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs which
amplify the above situations.
• Extended operation of unvented fuel burning devices
(range, oven, fireplace, etc.).
• Temperature inversions which can trap exhaust gasses
near the ground.
• Car idling
What CO detectors can and cannot do
CO Alarms provide early warning of the presence of CO,
usually before a healthy adult would experience symptoms.
This early warning is possible however, only if your CO
detector is located, installed, and maintained as described in
this user guide.
Because carbon monoxide is a cumulative poison, long-term
exposures to low levels may cause symptoms, as well as
short-term exposures to high levels. This unit has a timeweighted alarm; the higher the level of CO present, the sooner
the alarm will be triggered.
This CO detector can only warn you of the presence of CO. It
does not prevent CO from occurring, nor can it solve an
existing CO problem. If your unit has alarmed and you’ve
provided ventilation by leaving your windows and doors open,
the CO buildup may have dissipated by the time help responds.
Although your problem may appear to be temporarily solved, it
is crucial that the source of the CO is determined and that the
appropriate repairs are made.
CO detectors have limitation. Like any other electronic device,
CO detectors are not fool-proof. CO detectors have a limited
operational life. You must test your CO detector weekly,
because it could fail to operate at any time.
If your CO detector fails to test properly, or if its self-diagnostic
test reveals a malfunction, immediately have the unit replaced.
This detector will not monitor CO levels while in a trouble
condition.
Caution: This CO detector can only sense CO that
reaches the unit’s sensor. It is possible that CO may be
present in other areas without reaching the detector. The rate
and ability with which CO reaches the detector may be affected
by:
• Doors or other obstructions.
• Fresh air from a vent, an open window, or other source.
• Fresh air from a vent, an open window, or other source.
• CO being present on one level of the home and not
reaching a CO detector installed on a different level. (For
example, CO in the basement may not reach a detector on
the second level, near the bedrooms).
For these reasons, we recommend you provide complete
coverage by placing a CO Detector on every level of the home.
CO Detectors should not be used to detect the presence of
natural gas (methane), propane, butane, or other combustible
fuels.
Instruct children never to touch or otherwise interfere with the
alarm. Warn children of the dangers of CO poisoning.
Important warning statements
This CO detector is designed to detect carbon monoxide from
ANY source of combustion. It is NOT designed to detect
smoke, fire, or any other gas.
