Criterion 1 requires CO2 sensors to:
‘Visibly or audibly alert the asset owner or manager or users of the space when carbon dioxide levels exceed the recommended set point.’
This requirement can be met by an automatically generated email or other message format, provided it is demonstrated that such messages will be delivered to the appropriate person/people within a reasonable time.
This meets the intent of the criterion and may, in some cases, be a more appropriate solution.
