Scope

1.1 This Standard applies to single- and multiple-station carbon monoxide (CO) alarming devices and the CO portion of multi-criteria and multi-sensor (combination) alarms (hereafter referred to as devices). These devices are intended for use in ordinary locations in residential occupancies and include, but are not limited to, dwelling units, recreational vehicles and mobile homes, unconditioned areas, and facilities providing detention occupancy, treatment occupancy, and care occupancy.

1.2 This Standard applies to devices that are intended to protect against acute effects of exposure to CO. Devices are intended to alarm at CO levels below those which could cause a loss of ability to react to the dangers of CO exposure.
Devices are not intended to provide an alarm signal during long-term, low-level CO exposures or slightly higher short term transient CO exposure.
Devices, including the types that numerically display low (< 30 ppm) CO levels, are not intended to provide an alarm signal during long-term, low-level CO exposures or slightly higher short-term transient CO exposure.

1.3 This Standard also applies to remote accessories that might be connected to or are intended to be employed with a single- or multiple-station CO alarm. See more
