Part of Honeywell's 301C Controller range. Designed for simple installation and operation, the 301C continuously monitors and controls toxic gases, combustible gases and oxygen hazards.

Product Overview:

Using an addressable RS-485 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 abilities significantly reduce operational and maintenance costs.

Zoning / Averaging:

The 301C controller offers unique zoning capabilities which permit the averaging and comparison of multiple sensor readings. Zoning can reduce operational costs by ensuring that localized brief fluctuations registered at a single transmitter do not activate relays. For example, a car idling in a parking structure may locally increase a reading at a nearby transmitter. Rather than activating a fan as a result of the temporary localized fluctuation, zoning can be used to limit relay activation until the average reading for a zone exceeds a set-point. This can reduce run time of fans, yielding savings in both energy usage and wear and tear. The 301C has the capacity to manage input from three Modbus channels for up to 96 transmitters and up to 50 wireless transmitters that can be associated with up to 126 zones. Transmitters can belong to an unlimited number of zones, providing maximum operational and control flexibility.
