1 Safety Regulations
1.1 Correct Use
The PrimaX IR Gas Monitor - referred to hereafter as device - is a fixed infrared combustible gas detector. It is suitable
for outdoor and indoor applications, e.g. offshore industry, chemical and petrochemical industry, water and sewage
industry.
The device utilises infrared technology to monitor, detect and alert users to potentially dangerous levels of combustible
hydrocarbon gas. Dual source technology offers 100% redundancy on the optical source to maximize reliability and
lifetime. This device allows for extremely fast response time whilst providing an extremely stable output signal.
The device is a stand-alone unit with a 4 to 20 mA output with HART [Highway Addressable Remote Transducer] digital
information encoded on the analogue output. The signal of the transmitter can be used in combination with MSA control
units for further actions in safety or non-safety applications. Contact your MSA representative for available controllers.
The device is shipped factory-calibrated and is labelled with target gas, calibration gas and span setting information for
ease of use. Any user changes to the factory assigned values should be noted on the device labels.
The device is explosion-proof and suitable for installation in hazardous locations. This sensor is intended for integration
with a control system that can alert operations personnel to the presence of hydrocarbon combustible gas.
It is imperative that this operating manual be read and observed when using the product. In particular, the safety
instructions, as well as the information for the use and operation of the product, must be carefully read and observed.
Furthermore, the national regulations applicable in the user's country must be taken into account for a safe use. This
includes EN/IEC/UL/CSA 60079-29-2.
WARNING!
This product is supporting life and health. Inappropriate use, maintenance or servicing may affect the function of the
device and thereby seriously compromise the user's life.
Before use the product operability must be verified. The product must not be used if the function test is unsuccessful, it is
damaged, a competent servicing/maintenance has not been made, genuine MSA spare parts have not been used.
For safety reasons this equipment must be operated and serviced by qualified personnel only.
Failure to follow these warnings can result in serious personal injury or death.
Alternative use, or use outside this specification will be considered as non-compliance. This also applies especially to
unauthorized alterations to the product and to commissioning work that has not been carried out by MSA or authorized
persons.
1.2 Liability Information
MSA accepts no liability in cases where the product has been used inappropriately or not as intended. The selection and
use of the product are the exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect to the product are voided, if it is not
used, serviced or maintained in accordance with the instructions in this manual.

1.3 Safety and Precautionary Measures to be Adopted
WARNING!
• The device described in this manual must be installed, operated and maintained in strict accordance with the
labels, warnings, cautions, instructions, and within the limitations stated.
• Protect the device from extreme vibration.
• Do not mount the device in direct sunlight without a sunshield, since this may cause it to overheat.
• The only absolute method to ensure proper overall operation of the device is to check it with a known
concentration of the gas for which it has been calibrated. Consequently, calibration checks must be included as
part of the routine inspection of the system. The device is labeled with the type and value of the factory calibration
gas.
• Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual.
Failure to do so may seriously impair device performance. Repair or alteration of the device, beyond the scope of
these maintenance instructions or by anyone other than an authorized MSA service provider, could cause the
product to fail to perform as designed.
• There are no field-repairable internal components for this device. Return to MSA for warranty replacement per the
Warranty section.
• This device does not detect the presence of hydrogen gas and must never be used to monitor for hydrogen gas.
• The standard device must never be used in atmospheres containing acetylene gas. Contact MSA regarding
available acetylene sensors.
• Calibrate frequently if used in atmospheres exposed to high levels of solvents or dust. See chapters 4and 5for
calibration and cleaning procedures.
• Do not paint the device. If painting is done in an area where the device is located, exercise caution to ensure paint
is not deposited on the device. Such paint deposits could interfere with the device operation. Solvents in the paint
may also cause an alarm condition to occur.
• The device is designed for applications in hazardous areas under environmental conditions defined in the
Specifications section of this manual.
• The response time of the device can be increased by significant dust deposits. Checks for dust deposits must be
done at regular intervals.
• The device's sensor will detect other hydrocarbon gases than the target gas.
• Oxygen enriched atmospheres greater than 21Vol% can affect the measurement and the electrical safety of the
Gas Monitor. Do not use the device in these atmospheres.
• Do not use to detect combustible dusts or mists.
Failure to follow these warnings can result in serious personal injury or death.
1.4 MSA Permanent Instrument Warranty

2 Description
The device is designed to sample the environment at the installed location and alert the user to potentially dangerous
levels of hydrocarbon gas. The device is shipped factory calibrated and is labeled with target gas, calibration gas and
span setting information.
The output of the device is a standard 4 to 20 mA with HART. The 4-20 mA signal communicates the primary measured
value using the 4-20 mA current loop. Additional device information is communicated using a digital signal that is
superimposed on the analog signal. The device is compliant with HART Communications Foundation (HCF) Revision
7.0 format. Commercially available hand-held communicator devices or PC applications can be used to communicate
with the device using the Device Description (DD) file that is available from the HART Communications Foundation
website (www.hartcomm.org).
2.1 User Interface
This device does not provide a visual display of information. The gas level and basic device status are available via the
4-20mA output signal. Other detailed device status is available via the HART signal. Details about this interface can be
found in the PrimaX IR HART Specification located on the product CD shipped with the device.
The optional calibration cap provides an LCD display for easy and intuitive calibration of the device. The proper usage of
this calibration cap is described in chapter4.2 .
The device should be installed where gas leaks are anticipated. The installation position depends on the gas density,
either in the upper area of the room beneath the ceiling for gases lighter than air, or close to the ground for gases
heavier than air. Also consider how air movement may affect the ability of the device to detect gas. Testing for ventilation
patterns may be helpful in establishing locations for the device in enclosed areas.
Before beginning the installation, check that the delivered components are complete and correct,
referring to the shipping documents and the label on the shipment carton.
2.2 Package Contents
The device will be delivered with the following items in the shipping carton:
• PrimaX IR sensor (316 Stainless Steel)

3.1 Mechanical Installation
The device’s dimensions are shown below in inches (mm):
Figure 2 Sensor with Aluminum Junction Box
Figure 3 Sensor with Stainless Steel Junction Box
If a junction box is not being used, mount the device on a support by using suitable hardware (not supplied), and in
accordance with local regulatory requirements.
MSA recommends mounting the sensor horizontally. Horizontal mounting will help prevent the build-up of
particulate or liquid matter on the monitor's optical surfaces.
To ensure specified response time mount the sensor with the legs horizontal relative to each other as shown in Figure 4 .
