Gas Detection Systems

Two Channel Wall Mount Controller

The Beacon 200
The Beacon 200 is a powerful, low cost fixed system controller for
two points of gas detection. It is microprocessor controlled, 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, 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.
Two 10 amp rated relays per channel are strong enough to actuate
most external alarms and horns without using slave relays. The digital
display has backlighting and simultaneous readout of the gas type
and concentration.
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 of 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.
