The Model IR4000M Multi-Point Monitor can be used as an integrated combustible gas detection system, with capacity to connect eight IR400 point IR gas detectors and read their status with one command. 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 IR400s connected to it, at least once per second. To request the status and configuration data stored by the IR4000M, you can use an extensive set of menus that are easily navigated using a magnetic switch.
