The RKI Beacon 800 is an eight-channel fixed gas controller in a NEMA 4X polycarbonate, hinged-cover enclosure, with two 16-character by 4-line alphanumeric displays keeping all eight channels visible continuously. Two 10A relays per channel plus a common alarm/malfunction relay set give facilities programmable latch, reset, delay, and polarity control across the whole system.

Like RKI's smaller Beacon controllers, it accepts 4-20mA transmitters up to 8,000 feet away and runs on 85-264VAC or 24VDC with optional battery backup — a straightforward way to consolidate eight monitoring points into a single controller rather than deploying eight separate single-channel units.
