WARNINGS

• Read these installation instructions in their entirety before
proceeding. Leave these instructions with the owner/user
of this CO detection equipment.

• This product is intended for use in indoor locations of
dwelling units. It is not designed to comply with
Occupational Safety and Health Administration (OSHA)
commercial or industrial standards.

• The detector only indicates the presence of CO gas at the

Carbon monoxide alarm procedure

detector. Carbon monoxide gas may be present in other
areas.

• Failure to properly install, test, and maintain a CO detector
may cause it to fail, potentially resulting in loss of life.

WARNING: The carbon monoxide (CO) alarm indicates the

presence of CO, which can kill you. If the alarm signal sounds
four times, pauses for five seconds, and then repeats the
pattern:

1. Press the Test/Hush button at the detector or at the
control panel.

2. Move to fresh air immediately — outdoors or by an open
door or window. Check that all persons are accounted for.
Do not reenter the premises or move away from the open
door or window until emergency services responders have
arrived, the premises have been aired out, and your
detector remains in normal condition.

3. Call emergency services, the fire department, or 911:
Phone:

4. After following steps 1 to 3, if your detector reactivates,
repeat steps 1 to 3 and call a qualified appliance
technician to check for sources of CO from fuel-burning
equipment and appliances, and to inspect for proper
operation of this equipment.

Phone:

5. If problems are found during this inspection, have the
equipment serviced immediately. Note any combustion
equipment not inspected by the technician and consult the
manufacturer directly for more information about CO
safety for the equipment. Make sure that motor vehicles
are not, and have not been operating in an attached
garage or adjacent to the premises.

• Installation of this detector is not a substitute for proper
installation, use, and maintenance of fossil fuel-burning
appliances, including appropriate ventilation and exhaust
systems.

• To reduce the risk of CO poisoning, test the detector
operation when not in use for 10 days or more.

• This detector does not operate without electrical power. As
fires frequently cause power interruption, discuss further
safeguards with the authority having jurisdiction (AHJ).

• Do not paint the detector.

Notes

• Regulatory code may require that the system generate a
three-pulse temporal code (TC3) for fire alarms and a four­pulse temporal code (TC4) for CO alarms.

• The CO sensor is calibrated at the factory. CO sensitivity
is set to conform to UL 2034 requirements and cannot be
changed by the user. See “Specifications” on page 7 for
specific sensitivity values.

• To reduce the likelihood of nuisance alarms, ventilate
accommodation spaces when using household cleaning
supplies or similar contaminants. If a detector has been
exposed to such contaminants, test it promptly afterwards.

Symptoms of CO poisoning

The following symptoms related to CO poisoning should be
discussed with all occupants of the protected site.

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.

End of unit life indicator: The detector uses both a flashing

amber LED and intermittent sounder chirps (one rapid beep
every 15 seconds) to indicate that the detector needs
replacing. The detector also activates the trouble relay, which
can be monitored by a panel. As soon as possible, replace a
detector that reaches end of life because it may no longer
detect carbon monoxide accurately.

Common trouble relay: When connected to a listed control

panel, the trouble relay can report a trouble condition locally at
the panel and optionally at the monitoring station, if the system
is monitored. The trouble relay opens to indicate a trouble
condition upon lost power, CO sensor cell trouble, or unit end
of life.

1 ft. (0.3 m) from any wall.

The recommended CO detector locations are:

• Outside each separate sleeping area in the immediate
vicinity of the bedrooms (including areas such as hotel
rooms and dorm rooms)

• On every occupied level of a dwelling unit, including
basements, but excluding attics and crawl spaces

• Centrally located on every habitable level of the buildi ng
and in every HVAC zone based on an engineering
evaluation considering potential sources and migration of
carbon monoxide

• On the ceiling in the same room as permanently installed
fuel-burning appliances

• In any area required by local building codes, legislation, or
the authority having jurisdiction

• In a suitable environment per the detector specifications

WARNING: Potential loss of life. Failure to properly install,

test, and maintain a CO detector may cause it to fail. Connect
the CO detector only to a zone that is dedicated exclusively to
CO detection and that is monitored 24 hours a day. Do not
connect it to an initiating circuit with fire or security devices.

The 260-CO detector can connect to either UL 985 (Household
Fire Warning) or UL 864 (Commercial Fire) control panels. It is
not intended for use in industrial applications such as gasoline
refineries or parking garages, which require different listings.

Do not install the CO detector:

• Within 5 ft. (1.5 m) of any cooking appliance

• Within 10 ft. (3 m) of a fuel-burning appliance

• Near air conditioners, heating registers, or any other
ventilation source that may interfere with CO gas entering
the detector

• Where furniture or draperies may obstruct the airflow

• In a recessed area
