MSA Models 5100 Gas Monitor
The MSA Models 5100 Gas Monitor use a microprocessor-based control unit and any combination of MSA Series 5000 Sensors to detect combustible and toxic gases, as well as to monitor for oxygen deficiency. Applications for this universal monitor include parking garages, sewage treatment plants, oil production and processing, steel mills, chemical processing facilities, airport and bus terminals, combustible storage facilities, pipeline pumping stations, oil tankers and pharmaceutical plants.
Each MSA Monitor features a control unit that consists of a module with two completely independent channels. Each channel employs a three-digit LED display and three discrete alarm levels: caution, warning and alarm. Different color LED indicators differentiate each alarm level: yellow for caution, amber for warning and red for alarm. The alarm level for each channel can be displayed by a push-button. A second button, that also permits scrolling, lets you easily change the alarm levels.
The monitor can be used with either one or two remote sensors in any combination. A separate alarm relay output is provided for each alarm level (total of 6). The relays may be configured to be latching or non-latching, normally energized or de-energized, act on increase or decrease.
An optional small hand-held remote control allows the user to check or set alarm levels as well as access the calibration mode without opening the enclosure.
