Notifier VA201T User Manual

VA201T

The catalytic sensors of the 201T
can be used to detect hundreds of

different gases and inammable

vapour concentrations

The 201T gas
detection transmitter
is designed to meet
or exceed safety
requirements in a
variety of commercial
and industrial
applications.

The 201T series transmitters are
able to detect a wide range of toxic
and explosive gases. The 201T gas
detection transmitter can work in an
addressable network mode with the
301C controller through an RS-485
Modbus link. They can also be used

in a stand-alone conguration with

an optional 4-20mA or alarm relay
outputs.

The catalytic sensors of the 201T
can be used to detect hundreds of

different gasses and inammable

vapour concentrations. Toxic
gasses are detected by way
of electrochemical cells, while
metal-air battery cells are used to
detect oxygen. Moreover, a second
generation of semi-conductor
detectors offer a highly effective
solution for a variety of different
applications.
