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.

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.

Standard for the Installation of Carbon Monoxide (CO) Detection
and Warning Equipment. Place wall-mounted detectors at least

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 alarm panel activates.

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.

The sensor is no longer working. Replace the detector as soon as
possible.

Press the test/hush button to silence the detector for 36 hours.

Activates the trouble relay.

Notes

• Do not install CO detectors until after final construction
cleanup (unless otherwise specified by the AHJ).

• Leave this installation sheet with the owner/user of this
carbon monoxide (CO) detection equipment.

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.

The recommended CO detector locations are:

• Within 10 ft. (3 m) of all sleeping areas, including areas such
as hotel rooms and dorm rooms.

The 250-COPLT adapter plate

Use the 250-COPLT adapter plate when replacing a 240-COe with
a 250-CO to cover the footprint of the 240-COe. For example, use
the plate to cover different wall colors.

• In a suitable environment: areas with a temperature range of
32 to 104°F (0 to 40°C) and with a relative humidity range of 0
to 90% noncondensing.

• In residential dwellings, locate detectors in every bedroom,
within 10 ft. (3 m) of sleeping areas, and on each level. At a
minimum, place one detector outside the sleeping areas. See
Figure 1 on page 1.

The recommended CO detector locations in commercial
occupancies are:

• On every habitable level of the building based on an
engineering evaluation considering potential sources and

Installation

The 250-CO Carbon Monoxide Detector is a four-wire device
designed to use a Class 2 output from a UL 985 or 864 Listed
control panel or auxiliary power supply.

All wiring must conform to the NFPA 70 National Electric Code, UL
2075 Standard for Gas and Vapor Detectors and Sensors, NFPA 720

Standard for the Installation of Carbon Monoxide (CO) Detection
and Warning Equipment, and applicable codes. Use 14 to 22 AWG

wire.

migration of carbon monoxide

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

• On a firm, permanent surface

Do not install the CO detector:

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

• Near air conditioners, heating registers, or any other

WARNINGS

Connect the CO detector only to a zone dedicated exclusively to
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.

ventilation source that may interfere with CO gas entering the
detector

• Where furniture or draperies may obstruct the airflow

• In a recessed area

To install the detector (without the adapter plate):

1. Run the 250-CO detector wiring to the detector location.

2. Carefully remove the cover from the detector using a small,
flat screwdriver blade in the slot on the left side of the
detector cover.
