Effigy software is designed to facilitate fire and gas detector performance-based design as defined in ISA TR84.00.07. Effigy verifies an array of fire and/or gas detectors against the scenarios (consequences), validating that the locations and characteristics chosen will provide the coverage desired.
Fire and Gas Systems (FGS) are important tools for safeguarding process plants and production facilities that handle flammable and toxic materials. All such facilities have inherent risk, which in some cases require the installation of FGS to mitigate hazards. Kenexis performs design engineering of Fire and Gas Mapping (FGM) to determine where the detectors should be to sense the consequences and how the FGS should function for our clients. Continuing engineering and research have determined that accuracy of and repeatability of coverage analysis requires quality tools like Effigy.
Effigy was developed internally by our engineers that perform FGM, risk assessments, and design basis engineering. Their expertise is then enhanced in Effigy – Fire and Gas Mapping software. This combination of engineering and software development provides the most rigorous analysis tool, which results in the safest plant at the lowest cost by optimizing detector placement.

Geographic & Scenario Analysis
Analyzes detector location and characteristics based on geographic coverage or scenario coverage. Analysis considers the obstructions, consequences, detector equipment and settings used in the facility under study. Results provide a geographic risk profile that combines the thousands of consequences possible in a zone, calculates the detector coverage by zone, and maps the scenarios detected and not detected by the detectors.
Fire, Flammable Gas, Toxic Gas, Gas Cloud Imaging & Ultrasonic
Effigy supports generic detectors to allow development of the design throughout the engineering process up until detectors are actual chosen. Effigy also specifically models any brand of Fire, Flammable Gas, Toxic Gas, Gas Cloud Imaging & Ultrasonic detector, separately assessing all documented sensitivity settings of those detectors. The software comes with a database of most common detection equipment and associated performance metrics. Fire detection accurately models the cone-of-vision projections as detectors are moved away from the elevation of interest and rotated away from parallel using FM3260 Certified data.
Plume Modeling
Our patented Plume Model accurately models different fire sizes and materials of interest for each detector as required (e.g., methane, hexane, methanol). This substantially increases to accuracy of detection capabilities.
U.S. Pat. No. 10,600,057
ISA-TR84.00.07 Compliant
ISA-TR84.00.07 Guidance on the Evaluation of Fire, Combustible Gas, and Toxic Gas System Effectiveness provides guidance on risk and performance-based FGS design. After years of research, validation, and projects Kenexis developed Effigy to perform sophisticated and accurate coverage calculations based on either geography or consequence modeling to standardize the approach to achieving quantitative coverage targets into their fire and gas design processes.
3D CAD Import & 3D Analysis
Supports 3D STL import (most 3D CAD packages can export to STL), 3D model creation using basic shapes, and 3D analysis including the detector cone-of-vision, obstructions, and obstruction shadow orientation.
If you do not have a 3D CAD model, you can easily create a model in Effigy using geometric shapes from your plot plan.
Analyzes multiple obstruction geometries, in all orientations. After engineer the entire project in 3D, results are presented in color-coded graphical coverage maps and coverage tables indicating extent of the various coverage areas.

Effigy software is designed to solve the problem of where to put fire and gas detectors, why they need to be there, and how many detectors are required to achieve an acceptable level of protection. Based on ISA TR84.00.07, the software verifies an array of fire and/or gas sensors against the scenarios (consequences), validating that the locations and characteristics chosen will provide the coverage desired.

Functional Safety Assessment
Concerned about your first project?
Users our Fire & Gas Mapping Software – Effigy, can take advantage of additional fire & gas mapping training at no cost.
Additionally, for a reasonable fee, our fire & gas mapping engineers will perform a functional safety assessment of your project.
The objective of the FGM-FSA (Fire & Gas Mapping – Functional Safety Assessment) is to determine if the scope of work was performed in compliance with the ISA 84.00.07 Technical Report.
