XNX is an extremely flexible transmitter
that can be configured to accept an input
from any of the Honeywell Analytics range
of gas sensor technologies. It can also
be configured to provide a wide variety
of industry standard output signals.
This enables users to have a single type
of interface to all their gas detection needs,
even when different types of detectors are
employed, to most effectively address the
different gas detection applications on site.

The most effective gas detection systems often
employ a variety of detection technologies
including point flammable detectors (both
catalytic and infrared type), toxic and Oxygen
electrochemical cell type detectors and open
path infrared detectors. XNX provides a
common transmitter interface to all of these
and can be configured to provide industry
standard signal outputs to match the individual
requirement of each application or the preferred
site standard. If site output standards change,
XNX can be reconfigured to provide the new
required output. XNX has also been future­proofed by having the ability to have other
output modules fitted as new output standards
are developed and adopted by industry.

Having a common transmitter platform for
all your gas detectors brings further benefits.
Common tools and installation methods
simplifies and reduces cost of installation.
The common user interface makes operation
faster to learn and easier to navigate, thus
reducing time needed for training as well as
reducing the chance of incorrectly interpreting
messages or incorrectly changing settings.
Common spare parts also mean reduced
maintenance spares stock levels and cost for
all detectors.

XNX allows you to apply the most appropriate
gas detection technologies for each application,
standardise the interface to those detectors and
has the flexibility to provide the required signal
outputs. With XNX the answer is always yes.

XNX Transmitter

XNX has Worldwide hazardous area and
performance approvals and is housed in
a flameproof enclosure that is available in
either painted marine grade aluminum alloy
or stainless steel 316 versions. A large backlit
multilingual LCD clearly indicates the unit’s
status using a combination of text, digits and
icons. Users can modify its operation using
the LCD and magnet switches without ever
needing to open the unit. An optional local
IS HART® terminal port is also available.
Both enable one man, non-intrusive, operation
and reduce routine maintenance time and
costs. Local LEDs are also provided to indicate
the unit’s status at a glance.

XNX Transmitter Sensor Compatibility

XNX is compatible with all of the
Honeywell Analytics range of industrial fixed
gas sensors including Searchline Excel,
Searchpoint Optima Plus, Sensepoint (HT and
PPM) and Model 705. For further information
on these sensors, please refer to their individual
datasheets.

XNX with Searchpoint Optima Plus

The Multi Purpose Detector (MPD) is a
serviceable stainless steel sensor housing with
plug-in catalytic and infrared sensor cartridges.
The catalytic sensors measure flammable
gases in the range 0-100%LEL and the
infrared sensors measure Hydrocarbons in the
range 0-100%LEL, or Methane 0-100%LEL
(or 0-5%Vol) and CO2 0-5%Vol. See the
specifications section for full details of the
MPD sensor.

The XNX EC sensor is also a serviceable
stainless steel sensor with a wide range of toxic
and Oxygen plug-in sensor cartridges. The XNX
EC sensor interface to the XNX transmitter is
intrinsically safe, allowing the sensors to be
‘hot swapped’ without the need for a hot work
permit. This reduces the cost of ownership
by reducing the cost and time to service
the detector.

XNX Universal Transmitter

XNX Transmitter
Configuration

XNX has three basic personalities
(configurations) which support different
types of sensor. The personality boards and
optional output interfaces are enclosed in
the electronics POD (Personality, Options
and Display). The POD determines the
XNX transmitter behaviour based on the
sensor type attached to it and the selected
output options.

The mV (millivolt) personality is used for all
mV signal input sensors including MPD,
Sensepoint HT, PPM and the Model 705.
The EC (Electrochemical cell) personality is
for use with the XNX EC toxic and Oxygen
sensors. The IR (infrared) personality is for
use with the Searchline Excel open path and
Searchpoint Optima Plus point infrared gas
detectors.

The table below shows the three basic XNX
transmitter configurations and the sensors
each supports.

Outline Installation Dimensions

XNX has two integral mounting lugs on the transmitter body. The transmitter may be fixed directly to a surface, or to a horizontal or vertical pipe/
structure, Ø100-150mm (Ø4 to 6”) using a U bolt and pipe mounting bracket. Below are surface mounted outline installation dimensions for the
different XNX configurations.

Note: All dimensions are typical and are in millimeters. There are small differences in size between the aluminium version (shown) and stainless steel version. This does not effect the location of
the mounting holes.

XNX is designed for use in potentially explosive atmospheres. As such, installation should follow national guidelines using suitable mechanically
protected cable and glands (M25 or ¾” NPT) or conduit. Use 0.5mm2 (20AWG) to 2.5mm2 (~13AWG) cross sectional area cable as needed to
ensure minimum operating voltage at the detector, depending on installed cable length. Five M25 (ATEX/IECEx certified version) or ¾”NPT entries
(UL/CSA version) are provided. Entries are also used for either locally mounting a sensor or for accepting the cable/conduit from a remotely
mounted sensor.

Typical Maximum Cable Lengths

The maximum cable length between a
controller and detector is dependent upon:

• The minimum guaranteed supply voltage
from the controller

• The minimum operating voltage of the
detector

• The maximum current draw of the
detector

• The input impedance of the controller

• The resistance of the cable

Terminals on POD Module

All sensor connections and option module
connections are made at the terminal blocks
mounted on the rear of the removable POD
module.
The terminals provided are dependent on
which of the three basic personalities have
been selected plus the options selected.

The tables below show the different terminal
connections for each of the available POD
personality boards and options boards.

NOTES
Data taken at ambient conditions of 20°C, 50% RH. Data represents typical values of freshly calibrated sensors without optional accessories attached. *Accuracy at 10% of default full scale (typical A1 alarm) of applied gas, or minimum
(whichever is greater). Measured using calibration flow housing at calibration flow rate. Performance figures are applicable between 10 and 90% of full scale. Performance figures are measured by test units calibrated at 50% of full scale.
Contact Honeywell Analytics for any additional data or details. **Accuracy for operation between -20°C and -40°C is +/-30% of applied. Operation at these temperatures continuously (exceeding 12 hours) may cause deterioration in
sensor performance and shorten sensor life.

The remote sensor mounting kit (S3KRMK) allows the XNX EC sensors to be remotely mounted via an IS cable kit, up to 15 meters (50 feet) from the
transmitter. The kit includes 15 meters of shielded cable, cable glands and remote terminal box. The cable can be cut to the required length and terminated
at the remote terminal box.

The duct mounting kit (S3KDMK) can be used with the EC sensor to allow detection of flammable O
the MPD interface adapter (1226A0382), the duct mounting kit can accommodate the MPD to detect flammable gases in a duct application. The duct mount
kit includes the adapter, gasket and required fasteners. The MPD interface adapter includes only the adapter and requires the S3KDMK duct mount kit.

The calibration gas flow adapter is used to apply calibration test gas to the sensor. It push fills onto the bottom of the sensor and can
be fitted without removing the weatherproof cover.

The weatherproof cap protects the XNX sensors from harsh weather.

The collecting cone improves detection of lighter-than-air gasses such as Hydrogen and Methane.

The remote gassing kit enables gas to be applied remotely for performing functional response checks.
Kit includes 50' Teflon
