Beacon 200 Gas Detector Manual


The Beacon 200 is a powerful, 2 point, low cost fixed system controller that is microprocessor controlled, versatile, simple to install and operate.  It is capable of connecting RKI sensors directly for LEL level combustibles, Oxygen, Hydrogen Sulfide, or Carbon Monoxide.

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 wired remotely from the controller.  The digital display has backlighting capabilities and simultaneous readouts of the gas type and concentration.

The 10 amp rated relays are strong enough to actuate most external alarms and horns without using slave relays.  The Beacon 200's housing is rated NEMA 4X for corrosion resistance and a weather tight seal and complies with lock-out/tag-out standards.  An external reset switch allows the alarm to be silenced from outside the controller housing.  The Beacon 200 comes complete with a wall mounting kit for easy installation.

RKI offers the industry's widest selection of standard and toxic gas detection sensors, which can be utilized with the Beacon 200, providing gas monitoring protection for almost any application.
