3 Mounting and Location of Detectors
CAUTION
The location of the transmitters and sensors should be made in accordance with any relevant local
and national legislation, standards or codes of practice. Always replace detectors with a detector
of the same type. The detector should be mounted where the gas is most likely to be present. The
following points should be noted when locating gas detectors.
• Considerthepossibledamagecausedbynaturaleventse.g.rainor

currents.
NOTES:
The placement of detectors should be determined following the advice
of experts having specialist knowledge of gas dispersion, experts having
knowledge of the process plant system and equipment involved, safety and
engineering personnel. The agreement reached on the location of detectors
should be recorded.
CSA certication does not cover XNX EC cartridges or XNX EC cartridge
remote mounting kit, daisy-chained XNX combustible gas transmitters or the
use of HART
®
, Modbus, or Foundation Fieldbus used for combustible gas
performance. HART
®
, Modbus, or Foundation Fieldbus may be used only for
data collection or record keeping with regards to combustible gas detection.
FM approved congurations (see the XNX Universal Transmitter Technical
Manual, section 6.3 XNX Certications by Part Number Series) also limit the
use of HART
®
, Modbus, or Foundation Fieldbus to use for diagnostics, data
collection, or record keeping.
The XNX Universal Transmitter is certied and designed for installation and
use worldwide in hazardous areas.
3.1 Mounting the XNX Universal Transmitter
The XNX Universal Transmitter can be mounted in a number of different methods
using the integral mounting tabs.
Using the mounting tabs, the XNX can be attached to:
• Flatwallsurface
• Unistrut
®
With the optional Pipe Mount kit, the XNX can be mounted to pipe of diameter 2
to 6 in (50 to 150mm).
A ceiling mount bracket kit (1226A0358) is also available.
NOTES:
Agency certications require that EC and mV sensors face down. Optima
sensors must be mounted horizontally.
