General Monitors IR4000S Single-Point Monitor

Now obsolete, replaced by the S5000 Gas Monitor

The IR4000S Single-Point Monitor is a display and user interface for the IR400 point IR gas detector.

The monitor allows local calibration and displays gas concentration. It is housed in an explosion-proof junction box enclosure that can be installed in hazardous locations adjacent to the detectors.

Relays are optional. The relays provide output for Alarm, Warn, and Fault conditions.

Features & Benefits

  • Three-digit LED displays gas concentrations in % LEL, fault codes for troubleshooting and calibration prompts
  • An explosion-proof enclosure allows installation in hazardous locations
  • Optional 8-amp relays expand system functions.
  • Magnetic interface provides ease of maintenance and accessibility.

Applications

  • General Industry
  • Oil & Gas
  • Utilities
