What's in the Box

  • Wall mounting kit


The RKI Instruments Beacon 200 gas controller is a two point gas detection system for a variety of gases including LEL and toxic gases. It simultaneously displays gas type and concentration on the digital backlit display.

Sensors can be mounted directly at the Beacon 200 housing, or can be wired remotely from the controller. An external reset switch silences the alarm from outside the controller housing. The 10amp rated relays are strong enough to actuate most external alarms and horns without the use of slave relays.

Applications include petrochemical plants, refineries, water and wastewater treatment plants, pulp and paper mills, gas, telephone, and electric utilities, parking garages, manufacturing facilities, steel, automotive, and HVAC.
