FM Approval of the 4-20 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 FM Approval of the system, all
4-20 ma gas detection instruments connected to the input must also be FM Approved.
