Versatile, Scalable Gas Detection
The system’s IR4000M Multi-Point Monitor can connect up to eight IR400
Point IR Gas Detectors and read their status with one command, one
detector at a time. The IR4000M can also calibrate, gas check and zero
each IR400 sensor with a single command, reducing the cycle time for
routine maintenance. The monitor incorporates a display, relay module
and a data concentrator in an explosion-proof enclosure and magnetic
interface, which permits installation and calibration in hazardous
locations. Optional 8-Amp relays expand system functions, reducing the
need for integration with other controllers. Hart and Modbus permit the
device to convey device IDs, concentration readings and time-stamped
diagnostic, maintenance, and warning and alarm records to the control
room. General Monitors www.generalmonitors.com800.330.9161
