The Beacon 200 is a powerful, low cost fixed system controller for two points of gas detection. It is microprocessor con- trolled, versatile, simple to install and operate, and priced to be the industry’s most economical two point controller. It is capable of connecting directly to RKI sensors for LEL level combustibles, oxygen, CO2 and toxic gas sensors. The Beacon 200 can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC). Sensors can be mounted directly at the Beacon 200 housing, or can be wired remotely from the controller.
