XNX Universal Transmitter 
A universal transmitter compatible with all Honeywell Analytics gas sensor technologies.

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 future-proofed 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.

Pipe Mount Kit - 1226A0358
For use on pipes from 50-100mm (2-6 inches) in diameter. The kit includes: Pipe mount bracket, (2) carriage bolts, nuts and lock washers.

Remote EC Sensor Mounting Kit - SK3RMK
The remote sensor mounting kit (SK3RMK) 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.

Ceiling Mount Bracket Kit - 1226A0355

The optional ceiling mount bracket kit allows XNX to be mounted to a ceiling. The kit includes: (2) stainless steel ceiling mount brackets, bolts and nuts.

Duct Mount Kit - 3001A0408 and MPD Interface Adapter - 1226A0382

The duct mounting kit (3001A0408) can be used with the EC sensor to allow detection of flammable O2, CO, H2 and H2S gasses in ducts. When combined with 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 3001A0408 duct mount kit.

Calibration Gas Flow Adapter
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.
