Beacon 800 Gas Detector Manual


The Beacon 800 is a simplified, versatile, low cost fixed system controller for one to eight points of gas monitoring.

It is microprocessor controlled and is capable of accepting up to 8 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 115 VAC.  The 2 large digital displays have backlighting and easily identify both the as type and the gas concentration for all 8 channels simultaneously.

The Beacon 800 is also housed in a NEMA 4X rated case for a weather tight seal.  This case design complies with most lock-out/tag-out standards and can be fully secured.  The bottom mounted wiring hubs allow for easy wiring for the sensor transmitters, power, and alarm relay contacts.
