FMApproval
This approval does not include or imply approval of apparatus to which the subject instrument may be connected. In order to
maintain an FM Approved system, the apparatus to which this instrument is connected, must also be approved by FM
Approvals. As part of this approval, it was verified that optional communication functions of this gas detection instrument while
operating at the maximum transaction rate do not adversely affect the gas detection operation and functions of the instrument.
This approval, however, does not include or imply approval of the communications protocol or functions provided by the
software of this instrument or of the communications apparatus or software connected to this instrument.
The S5000 Transmitter, S5000 Junction Box, JB5000, Digital Sensors (H2S, 500 ppm H2S, CO, O2), and Passive MOS H2S
sensors also have FM Performance Approval for use in ordinary (nonhazardous) or hazardous locations.
