250-CO Carbon Monoxide
Detector Installation Sheet
Description
The 250-CO Carbon Monoxide 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.
The 250-CO provides a multicolored LED and a sounder to indicate
the detector status. Use Table 1 to determine the status of the
detector. The detector automatically resets when CO is no longer
detected.
The 250-CO Carbon Monoxide Detector is intended for indoordwelling 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 250-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.
The 250-CO detector is not intended to meet the requirements of
CAN/CSA-6.19 (Residential Carbon Monoxide Alarming Devices).
Please check with the local codes concerning the applicability of
this requirement for each installation.
The 250-CO detector has an optional adapter mounting plate. To
purchase the plate order P/N 250-COPLT-5PKG.
The built-in sounder is a supplementary alarm notification device.
The control panel is considered the primary alarm notification
device.
WARNING: Use only with a UL Listed control panel that recognizes
different alarm types (fire, burglary, CO, etc.) and that provides a
distinct notification for each type.
Sensor end of life indicator: The detector uses both a flashing
green LED and intermittent sounder chirps to indicated that the
detector needs replacing. The detector also signals a trouble
condition when the CO sensor reaches end-of-life. When
connected to a UL Listed control panel, the trouble relay can
report a trouble condition locally at the panel and optionally at the
central station, if the system is monitored.
Common trouble relay: The trouble relay opens to indicate a
trouble condition upon lost power, CO sensor cell trouble, or cell
end-of-life.
Figure 1: Recommended CO detector locations
Features
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. The hush feature does not
operate at CO levels above 350 ppm (parts per million).
Distinct 85 dB 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, pauses five seconds and then repeats
the pattern.

Testing
Test the detector after installation and regularly to verify that it is
functioning properly.
To test the CO detector:
1. To test the alarm and trouble relay panel connection, first
notify all persons and facilities that receive an alarm and
trouble signals (to prevent unnecessary response).
2. Momentarily press the test/hush button to start a test cycle.
During the test cycle the detector should beep four times with
a five second pause, then beep four more times. The LED
should flash red at each sounder beep. At the end of the test
cycle, the green LED illuminates for approximately four
seconds.
3. Momentarily disconnect the power supply from the detector
and verify that the common trouble relay opens.
4. Verify that the panel reacts correctly to the alarm relay
activation.
5. If the detector fails the test, verify that the power leads are
connected properly, wait briefly then try again. If the detector
fails again, replace it.
Maintenance
Clean the detector as needed with a clean cloth (either dry or
dampened with water) to keep openings free from dust and dirt.
Test the detector regularly.
Do not paint the detector or expose it to cleaning solutions.
Notification
Notification of carbon monoxide detectors should be consistent
with NFPA 720 and the local AHJ. Notification zones should be
consistent with the emergency plan for the protected premises.

General limitations of CO detectors
CO detectors require a source of power to work. Verify that the
green LED on the detector is flashing at all times. Since this unit is
powered by a control panel, it may not operate during a power
failure or if the control panel is disabled.
WARNING: This product is intended for use in ordinary indoor
locations of family living units. It is not designed to meet
compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards.
The 250-CO detector is not intended to meet the requirements of
CAN/CSA-6.19 (Residential Carbon Monoxide Alarming Devices).
Please check with the local codes concerning the applicability of
this requirement for each installation.
People with special medical problems should consider using
specialized detection devices with less than 30 ppm (parts per
million) alarming capabilities.
This detector only indicates the presence of carbon monoxide gas
at the detector. CO may be present in other areas. Anything
preventing CO from reaching the detector, such as closed doors,
could delay or prevent detector activation.
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 carbon monoxide levels.
CO detectors are not smoke detectors: This detector is designed
to detect CO from any combustion source. It is not designed to
detect smoke, fire, or any other gas.
CO detectors may not be heard: A sound sleeper, or someone
who has taken drugs or alcohol, may not awaken if the detector is
installed outside a bedroom. 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 life insurance: 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.
