Principles of Operation

A single control knob turns the instrument on and sets the detection filament voltage. Gas concentrations up to 100 percent of LEL are measured directly on the meter. Concentrations in the explosive range are indicated by full-scale deflection of the meter pointer.

Approvals and Standards

Model 2A is listed by Underwriters' Laboratories (UL) for use in hazardous locations as defined by the National Electrical Code. UL approval is for Class I, Group D, Divisions 1 and 2; and Class I, Groups A, B and C, Division 2 (Division 1 excluded), hazardous atmospheres.

Hazards

Combustible Atmosphere

Product Information

Detects and measures concentrations of combustible gases or vapors in the air. This instrument can be used in the immediate environment or, with sampling lines and probes, it can draw samples from remote areas and is housed in a cast aluminum case.

Principles of Operation

The FiveStar Alarm can automatically compensate for changes in atmospheric pressure, and has a battery gas gauge which indicates, in tenths of hours, how much longer the instrument can run on the remaining battery charge.

For added protection, MSA's Lockalarm™ Circuit ensures that the unit will remain in alarm mode whenever combustible gas levels reach 100 percent of the LEL (Lower Explosive Limit).

Small and lightweight, the FiveStar Alarm is convenient to carry in hand or clip to a belt. It can also be left unattended for continuous monitoring.

Approvals and Standards

The FiveStar Alarm has been approved for use in Class 1 Division 1, Groups A, B, C and D; Class II, Division 1, Groups E, F, G; and Class III hazardous locations.
