42、OR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover electrically operated single and multiple station carbon monoxide (CO) alarms intended for protection in ordinary indoor locations of dwelling units, including recreational vehicles,
43、mobile homes, and recreational boats with enclosed accommodation spaces and cockpit areas. 1.2 Carbon monoxide alarms covered by these requirements are intended to respond to the presence of carbon monoxide from sources such as, but not limited to, exhaust from internal-combustion engines, abnormal
44、operation of fuel-red appliances, and replaces. Carbon monoxide alarms are intended to alarm at carbon monoxide levels below those that cause a loss of ability to react to the dangers of carbon monoxide exposure. See Table 41.1, Part A, Alarm carbon monoxide concentration and response time. 1.3 Carb
45、on monoxide alarms covered by this standard are not intended to alarm when exposed to long-term, low-level carbon monoxide exposures or slightly higher short-term transient carbon monoxide exposures, possibly caused by air pollution and/or properly installed/maintained fuel-red appliances and replac
46、es. See Table 41.1, Part B, False alarm resistance specications. 1.4 These requirements, where applicable, also cover all remote accessories that may be connected to or are intended to be employed with a single or multiple station carbon monoxide alarm. See 37.2.1. 1.5 This standard does not cover t
47、he following: a) Single and multiple station smoke alarms that are covered by the Standard for Smoke Alarms, UL 217, or the Standard for Smoke Alarms, ULC-S531. b) Smoke alarms of the nonself-contained type that are intended for connection to a household or industrial system control unit. These are
48、included in the Standard for Smoke Detectors for Fire Alarm Systems, UL 268, or the Standard for Smoke Detectors, Fire Alarm, ULC-S529. c) Mechanically operated single and multiple station re alarm devices that are specied in the Standard for Single and Multiple Station Heat Alarms, UL 539, or the S
49、tandard for Heat Actuated Fire Detectors, Fire Alarm, ULC-S530. d) Heat alarms whose requirements are covered in the Standard for Heat Detectors for Fire Protective Signaling Systems, UL 521, or the Standard for Lined Building Protection Fire Hose, ULC-530. e) Carbon monoxide gas detectors intended for use in hazardous locations as dened in the U.S. Coast Guard Electrical Engineering Regulations.
