The 301C continuously monitors and controls toxic gases, combustible gases and oxygen hazards. Designed for installation and operational simplicity, the VA301C reduces the cost of installation and ownership.

Using an addressable RS-486 Modbus communication protocol, the 301C uses daisy chain wiring requiring only 2 pairs of wires to connect up to 96 transmitters on the 3 input channels.  This simplifies installation, in turn lowering costs.  The 301C's zoning and averaging capabilities reduce operational and maintenance costs.
