Approval of the transmitter does not include, or imply, approval of apparatus to which the
transmitter may be connected and which processes the electronic signal for the eventual end
use. In order to maintain FMRC approved system, the control instrument, to which the subject
instrument is connected, must be FMRC approved.
The following sensors have been FMRC approved for use with the Model S4000C:
•
10001-1 Aluminum Body General Purpose Combustible Gas Sensor
•
10058-1 Stainless Steel Body General Purpose Combustible Gas Sensor
The following apparatus have been FMRC approved (although they have not been verified as
part of a Model S4000C system):
•
Model DC110 Eight Channel Readout/Relay Display Module
•
Model DC130 Dual Channel Readout/Relay Display Module
Factory Mutual Research Corporation has tested the Model S4000C according to the criteria
listed under the FMRC Approval Standards for Combustible Gas Detectors, Class Numbers
6310 & 6320.
FMRC has tested the Model S4000C using the specifications listed in Section 9.2. This permits
an operating temperature of -40°F to +167°F (-40°C to +75°C), a general purpose sensor
(10001-1 or 10058-1) attached to the housing (i.e. not remote), calibration performed with a
General Monitors’ Portable Purge Calibrator using 50% LEL gas (Methane, Hydrogen,
Butadiene, Butane, Ethane or Propane) and the procedure listed in Section 4.5. The conduit
containing wires connected to the relay contacts must be sealed. If the non-latching relay
option has been selected from the relay options, the user must provide alternate means of
latching the relay output.
