Gas Detection Systems

Single Channel Wall Mount Controller

The Beacon 110
The Beacon 110 is a powerful, low cost fixed system controller for
one point of gas detection. It is microprocessor controlled, versatile,
simple to install and operate, and priced to be the industry’s best
value single gas detection controller. It is capable of accepting RKI
sensors directly for LEL level combustibles, Oxygen, CO 2 , and toxic
gas sensors. The Beacon 110 can also accept any 4-20 mA trans-
mitter (2 or 3 wire, 24 VDC). Sensors can be mounted directly at the
Beacon 110 housing, or can be wired remote from the controller.
Two 10 amp rated relay contacts allow direct control of external
alarms and horns. The digital display has backlighting and
simultaneous readout of the gas type and concentration.
The Beacon 110 is also housed in a NEMA 4X rated case for a
weather tight seal. This case design complies with lock out/tag out
standards and can be fully secured. An external reset switch allows
the alarm to be silenced from outside of the controller housing.
The Beacon 110 ships complete with a wall mounting kit for easy
installation.
RKI offers the industry’s widest selection of standard and toxic gas
detection sensors, all of which can be utilized with the Beacon 110,
providing gas monitoring protection for almost any application.
