UL 2034-2008 UL Standard for Safety Single and Multiple Station Carbon Monoxide Alarms (Third Edition; Reprint with revisions through and including February 20@ 2009)
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@ mobile homes@ and recreational boats with enclosed accommodation spaces and cockpit areas.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 operation of fuel-fired appliances@ and fireplaces. 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 38.1@ Part A@ Alarm ?C carbon monoxide concentration and response time.Carbon 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-fired appliances and fireplaces. See Table 38.1@ Part B@ False alarm resistance specifications.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 34.2.1.This standard does not cover the following: a) Single and multiple station smoke alarms that are covered by the Standard for Single and Multiple Station 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 included in the Standard for Smoke Detectors for Fire Protective Signaling Systems@ UL 268@ or the Standard for Smoke Detectors@ Fire Alarm@ ULC-S529. c) Mechanically operated single and multiple station fire alarm devices that are specified in the Standard for Single and Multiple Station Heat Detectors@ UL 539@ or the Standard 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 defined in the U.S. Coast Guard Electrical Engineering Regulations.A product that contains features@ characteristics@ components@ materials@ or systems new or different from those covered by the requirements in this standard@ and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features@ characteristics@ components@ materials@ or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development@ revision@ and implementation of this standard.?
