The RKI Instruments Beacon 800 gas controller is a versatile, low-cost fixed system controller for one to eight points of gas detection. It is microprocessor controlled and is capable of accepting up to eight separate 4-20 mA sensor transmitters, which can be either 2- or 3-wire. The Beacon 800 can be powered by either 24 VDC or 85-264 VAC. It is simple to operate and comes complete with a wall mount installation kit.

The two large digital displays have backlighting, and easily identify both the gas type and the gas concentration for all eight channels simultaneously. The Beacon 800 is housed in a NEMA 4X-rated case for a weathertight seal. This case design complies with lock out / tag out standards and can be fully secured. An external reset switch allows alarms to be silenced from outside the controller housing. The bottom mounted wiring hubs allow for easy wiring.

With 3-amp rated relays, the Beacon 800 can be wired directly to a variety of devices like alarm horns, buzzers, or lights. This eliminates the need for costly external relays from the controller to devices. RKI offers a wide selection of standard and toxic gas detection sensors, which can be used with the Beacon 800, providing gas monitoring protection for almost any application.
