Detector locations
Selecting a suitable location is critical to the operation of CO
detectors. Install the 250-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.
The recommended CO detector locations are:
•
Within 10 ft. (3 m) of all sleeping areas, including areas such
as hotel rooms and dorm rooms.
•
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
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
ventilation source that may interfere with CO gas entering the
detector
•
Where furniture or draperies may obstruct the airflow
•
In a recessed area

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.
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.
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.
To install the detector (without the adapter plate):
1.

Description
The detector has power and is functioning properly.
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.
Activates the trouble relay.
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.
Run the 250-CO detector wiring to the detector location.
Carefully remove the cover from the detector using a small,
flat screwdriver blade in the slot on the left side of the
detector cover.
