• IR4000M can connect to as many as eight remote IR400 detectors • Operates as an integrated gas detection system with voting • IR4000M onboard data concentrator reads status for up to 8 devices at once with one command • Useful in large, multi-point systems • IR4000M can calibrate, gas check and zero multiple IR400 devices based on a single command • Provides ease of maintenance and accessibility • Explosion-proof enclosure and magnetic interface • Allows installation and calibration in hazardous locations Single / Multi-Point Monitors for use with Model IR400 Point IR Gas Detector • Expands system functions, potentially eliminating the need for additional equipment like a PLC Description The IR4000 Monitor is available in two options. The Model IR4000S is a Single-Point Monitor and the Model IR4000M is a Multi-Point Monitor. Both feature a threedigit LED display and user interface to our Model IR400 point IR gas detector. The monitor allows local calibration and displays gas concentration. Both are housed in an explosion-proof junction box enclosure that can be installed in hazardous locations adjacent to the detectors. Optional relays for both monitors provide output for Alarm, Warn, and Fault conditions occurring at each detector. Users can select operating mode, warn, and alarm setpoints via a magnetically activated switch. The relays are user-programmable as Latching or NonLatching, normally De-Energized or normally Energized. Latching relays can be reset via a remote reset input or via the magnetic switch. The Model IR4000M Multi-Point Monitor is a display, relay module, and a data concentrator. It provides monitoring and control functions for up to eight connected IR400 gas detectors. The highest current % LEL among all connected detectors is shown continuously during normal operation. In addition, the IR4000M reads seven data items from each of the IR400ʼs connected to it, at least once per second. An extensive set of menus are navigated using a magnetic switch to request the status and configuration data stored by the IR4000M. In addition, over 200 IR4000M and IR400 Modbus registers provide the greatest possible flexibility in reviewing current status data and settings, and configuring operating parameters. For example, the IR4000M can report % LEL data for all eight detectors with one command, which is useful in large multi-point systems. Applications • Chemical Plants • Compressor Stations • Drilling and Production Platforms • Fuel Loading Facilities • LNG/LPG Processing and Storage Facilities • Oil Well Logging • Refineries • Wastewater Treatment Facilities
