Unpacking
After opening the package and removing the equipment and
components, make sure that you have all the items described on the
order form or packing slip.
Description
The 201T Series transmitters are able to detect a wide range of toxic
and explosive gasses. The transmitters can operate in stand-alone or
network mode via their optional 4-20mA or relays.
Catalytic sensors are used to detect hundreds of different gasses and
inflammable vapor 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.
Installation Guidelines
These guide lines must be strictly observed to assure that the
equipment will work properly. If they are not applied, Honeywell will not

• Make sure to locate all units easily accessible for proper service.
• Avoid any location where units could be subject to vibrations.
• Avoid any location close to any electromagnetic interference.
• Avoid any location where there are large temperature swings.
• Verify local requirements and existing regulations which may affect
the choice of location.
