Beacon 110 : 1 Channel Wall Mount Controller
เนื้อหา



Gas detection should not be complicated. The Beacon 110 is gas detection simplified.
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, Hydrogen Sulfide, or Carbon Monoxide. 
The Beacon 110 can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC). Sensors can be 
mounted directly at the Beacon 110 housing, or can be wired remote from the controller.

The 10 amp rated relays are strong enough to directly power 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, which can be 
utilized with the Beacon 110, providing gas monitoring protection for almost any application.
