Application
The SafeAir 260-CO Carbon Monoxide Detector is intended for
ordinary indoor-dwelling unit applications in both residential and
commercial occupancies, including single/multiple family residential
occupancies, hotel rooms, dorm rooms, and other areas approved
by the authority having jurisdiction (AHJ). 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 indus-
trial applications such as gasoline refineries or parking garages,
which require different listings.
The 260-CO is a four-wire device that uses a Class 2 output from
a control panel. Nonetheless, the primary alarm notification de-
vice remains the 260-CO’s internal sounder with the control panel
secondary to these purposes. The 260-CO is not a substitute for life
safety devices, and should be only considered as an integral part of
a comprehensive safety program.
Selecting a suitable location is critical to the correct operation of
CO detectors. Install the 260-CO in accordance with NFPA 720
Standard for the Installation of Carbon Monoxide (CO) Detection
and Warning Equipment. Place wall-mounted detectors at least
5 ft. (1.5 m) up from the floor. For ceiling mounted applications,
place the detector at least 1 ft. (0.3 m) from any wall.
Recommended CO detector locations:
9Within 10 ft. (3 m) of all sleeping areas, including areas such
as hotel rooms and dorm rooms.
9In a suitable environment: areas with a temperature range
of 40 to 100 °F (4.4 to 37.8 °C) and with a relative humidity
range of 10 to 90% noncondensing.
9In residential dwellings, locate detectors in every bedroom
and on each level. At a minimum, place one detector outside
the sleeping areas.
Recommended locations for CO detectors
Always check with your local building codes,
legislation, and Authority Having Jurisdiction
for specific CO location requirements in your area
Recommended CO detector locations in commercial occupancies:
9Outside each separate sleeping area in the immediate vicinity
of the bedrooms (including areas such as hotel rooms and
dorm rooms)
9On every occupied level of a dwelling unit, including base-
ments, but excluding attics and crawl spaces
9Centrally located on every habitable level of the building and
in every HVAC zone based on an engineering evaluation con-
sidering potential sources and migration of carbon monoxide
9On the ceiling in the same room as permanently installed fuel-
burning appliances
9In any area required by local building codes, legislation, or the
authority having jurisdiction
9On a firm, permanent surface
Do not install the CO detector:
8Within 5 ft. (1.5 m) of any cooking appliance
8Within 10 ft. (3 m) of a fuel-burning appliance
8Near air conditioners, heating registers, and any other ventilation
source that may interfere with CO gas entering the detector
8Where furniture or draperies may obstruct the airflow
8In a recessed area
Operation
SafeTest functional test: This test facilitates the use of CO test
spray to verify the correct operation of the detector, which is man-
datory per NFPA 720. The SafeTest mode is activated by pressing
and holding the test/hush button for 5-10 seconds. While in Saf-
eTest mode, directing UL-classified CO testing spray at the sensor
port will result in the activation of the alarm relay, and the sounder
and red LED in a temporal-four pattern. Pressing and holding the
test/hush will exit SafeTest mode.
Distinct temporal-four sounder alarm: The 85 dB temporal-
four sounder provides a distinctive alarm notification that is easy
to differentiate from smoke alarm notification devices. The alarm
beeps four times, rests five seconds and then repeats the pattern.
Test/hush button: Use the test/hush button to test the alarm and
silence an activated alarm. Pushing the test/hush button silences
the integral sounder for five minutes. The red alarm light stays on
and if CO is still present after five minutes, the detector once again
sounds in the temporal-four pattern.
End of sensor life indicator: The detector uses both a flashing
green LED and intermittent sounder chirps to indicate that the de-
tector needs replacing. To silence the detector, push the test/hush
button. The detector also begins signaling a trouble when the CO
sensor is approaching end-of-life.
Common trouble relay: The trouble relay opens to indicate a
trouble condition upon lost power, CO sensor cell trouble, or cell
end-of-life. When connected to a listed control panel, the trouble
relay can report a trouble condition locally at the panel and option-
ally at the central station, if the system is monitored.
WARNINGS: Connect the CO detector only to a zone dedicat-
ed exclusively for CO detection and that is monitored 24 hours
a day. Do not connect to an initiating circuit with fire or security
devices. Failure to properly install, test, and maintain a CO
detector may cause it to fail, potentially resulting in loss of life.
