Table 1: Detector status indications
Status LED Sounder Description
Safe air Green, 1 pulse every
15 seconds No sound The detector has power and is functioning properly.
Alarm Red, pulses with
sounder Sounds four rapid beeps every
five seconds or every minute
after five minutes in the alarm
state Dangerous levels of CO are present. Evacuate the premises.
Press the test/hush button to silence the sounder for five minutes.
Activates the alarm relay. If connected, the control panel activates.
Trouble Amber, pulses with
sounder Sounds one rapid beep every
45 seconds There is a problem with the detector and the detector is not working
properly. Contact the service company to correct the trouble and
replace the detector, if necessary.
Press the test/hush button to silence the detector for nine hours.
Activates the trouble relay.
End of unit life Amber, pulses with
sounder
Sounds one rapid beep every
15 seconds Replace the detector as soon as possible.
Press the test/hush button to silence the detector for 36 hours.
Activates the trouble relay.
Loss of power No LED No sounder Activates the trouble relay.
Tandem
interconnect No LED Sounds four rapid beeps every
five seconds or every minute
after five minutes The detector in alarm causes the sounds to activate on the detectors
that are not in alarm. Evacuate the premises.
Press the test/hush button to silence the sounder for five minutes.
Distinct 85 dB temporal-four alarm: The 85 dB sounder
provides a distinctive temporal-four alarm notification that is
easy to differentiate from smoke detector notification devices.
The alarm beeps four times, pauses five seconds, and then
repeats the pattern.
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.
Installation
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.
Detector placement
Install detectors according to applicable codes and standards.
Place wall-mounted detectors at least 5 ft. (1.5 m) up from the
floor. For ceiling mounted applications, place detectors at least
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 building
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
(see “Specifications” on page 7 for details)
• On a firm, permanent surface
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
