NOTE
Sensor cross sensitivity has not been verified by FMRC.
NOTE
FMRC Approval of the 4 to 20 ma input does not include or imply approval of the gas detection apparatus such
as sensors, transmitters, or devices connected to the system. In order to maintain FMRC Approval of the
system, all 4 to 20 ma gas detection instruments connected to the input must also be FMRC Approved.
