Detector Placement
 Open path detectors should be installed based on
several considerations:
– Hazard conditions within the installation area covered
– Ventilation rates, direction, and presence of recirculation and
dead zones
– Sensitivity to low (geometric) sunlight, fog, and reflections
– Powerful sources of electromagnetic emissions like high
powered electrical towers
– Structures that may interfere with line of sight
* Health and Safety Executive, Offshore Division,” Fire and Explosion Strategy, Issue 1,” 2004.
Installation
 When installing an ULTIMA OPIR-5 detector, it is useful
to consider the following:
–
–
–
–
–
–
–
–
Vibration can create issues
Solid foundation improves alignment integrity
The longer the line of sight path, the more solid the foundation required
Maintain a 6” to 12” radius around the line of site beam to avoid reflective
interference from piping and supports
For outdoor installations, consider maximum snow levels
Good immunity to fog, steam, and rain but immunity degrades over longer
distances
Avoid pedestrian traffic or overhead cranes
Keep beam low and down wind for heavy gases like propane and high for light
gases like methane

Split Concentration Range
 With the split range function, users can monitor the
entire span of gas concentration with a single analog
signal
– Reduces wiring and commissioning costs

Alignment
 Simple alignment process
– Arm or base mounts available
 Display
– Menus activated by magnet
– Enables easy alignment, setup
& diagnostics
Maintenance
 As with other combustible sensors, the ULTIMA OPIR-5
should be included in the plant maintenance schedule*
– Gas check frequency depends on operating conditions (ex.
dusty, corrosive, or damp environment)
– Before repair or maintenance, the gas detector should be
removed to a safe place outside the area being protected
 If the hazard is still potentially present, it will be necessary to
use a replacement gas detector in the area until the original
detector is reinstated
* BS EN 50073:1999 “Guide for the selection, installation, use and maintenance of apparatus for the detection and measurement of
combustible gases or oxygen.”
Diagnostics
 The ULTIMA OPIR-5 has
self-diagnostics that inform
users when certain types of
device failures have
occurred

HART
 The ULTIMA OPIR-5 is available with HART for better
efficiency with remote communication
– Only the primary scale, LEL•m or split range, connects through
HART
 Benefits of the HART-equipped ULTIMA OPIR-5:
– Better diagnostics of problems
– Improved management of maintenance history and event logging
– Flexible and accurate digital transmission
– Effective cost control of devices in the field
– Installation savings due to fewer wires
HART – Analog Signal for Faults
Because HART requires a minimum current for
operation, the ULTIMA OPIR-5’s fault conditions use 3.5
mA as minimum analog output

AMS Device Manager
 Asset management and
process improvement
– Check compliance to
calibration schedule
– Coordinate calibrations so
as to reduce labor cost
– Aggregate calibration to a
control room
– Track gas level remotely
– Read fault conditions from
control room; before
sending technician to the
field
Applications

Sales Strategies
 The ULTIMA OPIR-5 is a product with all time
firsts:
– First and only open path detector to meet agency
performance requirements on both LEL and ppm scales
– First among major open path models to be certified to
FM Approvals, EN, and IECEx performance standards
– First to offer split range scale for ppm-m and LEL-m
monitoring
– First to be certified for operation at -55C
Sales Strategies (Continued)
 No tools required for alignment at
any range
– It is possible to align the open path
detector without a scope at 100 m
or more
 Integral display
– Reduces installation time and total
cost to own
Conclusion
 The Ultima OPIR-5 compares well with other
open path detectors in the market
• Repeatability
• Linearity
• Operating temperature range
Conclusion (Continued)
 The instrument’s dual concentration range and integral
display are differentiators
– No other detector offers a performance-certified dual range
– Most commercial models require a handheld or controller to read
gas concentrations or perform maintenance
 The Ultima OPIR-5 open path detector is well positioned
to meet users’ demands for enhanced safety and
longevity
