The safety products you have purchased should be handled carefully and installed,
calibrated, and maintained in accordance with the respective product instruction manual.
Remember these products are for your safety.
Special Warning
Through engineering design, testing, manufacturing techniques, and rigid quality control,
General Monitors (GMI) supplies the finest gas detection systems available. The user
must recognize his responsibility for maintaining the gas detection system in operational
condition.
The Model 580A Two Channel Combustible Gas Monitor contains components, which
can be damaged by static electricity. Special care must be taken when wiring the system,
to ensure that only the connection points are touched.
Only catalytic bead sensors designed by General Monitors will work with the Model 580A
Controller. Any attempt to use a sensor that has not been approved by General Monitors,
will void the warranty.
General Monitors cautions, as with all equipment of this type, that high levels or long
exposure to certain atmospheres will “poison” the sensor catalyst and eventually affect
sensitivity. Please refer to Section 2.5.5 for specific information. Use in such
atmospheres requires calibration checks on a more frequent schedule than normal.
General Monitors should be consulted for an application feasibility determination, before
installing a system in such atmospheres.
General Monitors’ sensors and sensor housings are designed and tested for use in
certain classes of hazardous atmospheres. Explosion-proof integrity cannot be
maintained, if sensors and sensor housings are operated in other than the “as designed”
condition. Terminal access covers of sensor housings must be securely fastened. Sensor
housing must be installed in accordance with National Electrical Code acceptable
practices, for the class of hazardous atmospheres.
