1.0 Introduction
1.1 Notice
This Chapter provides a brief description of the Model S800 and its’ features & benefits.
More detailed information on the features and benefits listed in section 1.2 will be presented
in later chapters.
The S800 is easy to install and operate; however, this manual should be read in full, and the

1.2 General
The General Monitors Model S800 Smart Methane Monitoring System is a single
channel monitoring system designed specifically for the mining industry for installation
on longwalls, continuous miners and other face cutting equipment. It is supplied
through our exclusive mining distributor, United Central Industrial Supply (UCISC).
UCISC should be consulted if service beyond the scope of this manual becomes
necessary.
The Model S800 is based upon General Monitors latest sensing technology and consist
of an S800 Power Supply Module, a remote mounted catalytic bead sensor in its own
explosive-proof housing, and a large LED display (approximately two inches high
available in yellow or red) incorporated into an explosion proof (XP) housing.
The basic system is a single channel unit; however, two channel operation may be
achieved by adding an additional display unit and an additional sensing unit.
1.3 Features and Benefits
Single Point, Auto-Calibration:
the unit’s display indicates simple automated
calibration prompts to the operator with no adjustments of “zero” and “span” required.
Microprocessor Based Electronics: Monitors fault conditions and sensor inputs and
provides outputs in the form of display codes and relay contacts.
Power On Self Test (POST): this is a test that is performed by the microprocessor
each time power is applied to the S800.
LED Test: tests the integrity of each LED and each segment of the digital display.
Ramp Test: tests the functionality of the instrument through the microprocessor
ramping up in the signal from the present gas level to full scale and back.
The Model S800 Smart Methane Monitoring System is approved for use by The
Mine Safety and Health Administration (MSHA).
