Honeywell 301C Data sheet

301C

Gas detection network controller
offering safety, energy efficiency,
and ease of installation

The 301C Controller continuously monitors
and controls toxic, combustible, and
refrigerant gases as well as oxygen.
Rely on the 301C for safety, energy
efficiency, and easy installation of your
gas detection network.

Using an addressable RS-485 communication protocol, the 301C uses
daisy chain wiring to connect up to 96 transmitters in three loops.

This simplies installation, in turn lowering costs. The 301C’s powerful
zoning, voting, and averaging abilities signicantly reduce operational
and maintenance costs. And what’s more, the newly updated 301C cuts

commissioning time and hassle.

Flexible Logic Capabilities Reduce Operational Costs

Choose the 301C as the centerpiece for building a gas detection network
compliant with the industry’s most demanding safety and energy guidelines,
such as California Title 24 Part 6. The 301C controller offers automatic
sensor identication and unique zoning capabilities which permit the
grouping of multiple sensor readings. Readings from transmitters in a given

zone can be evaluated via averaging or voting. For example, voting can be

used to activate fans only when one-third of the sensors in a zone report

gas. This can avoid an excessive response to a single car idling. Time delays

can be congured at the leading edge of a gas response (to prevent false
alarms) or on the trailing edge (to reduce power cycling of a fan.) Outlier
detection can be used to identify when a single sensor reading is higher
than others. Responses can also be made conditional on time of day, day of
week, or other external input. This exibility can precisely match the needs of
each installation, thus saving energy and extending equipment life.
