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.
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.
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.

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
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.
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.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.
