Study MethodologyStudy Methodology
1. Prepare performance targets
2. Collect applicable drawings of equipment installation
3. Survey the areas of interests w/ digital photographs
4. Assess the performance of existing detection using custom software
5. Identity gaps between ‘actual’ and ‘required’ performance
6. Propose measures to close these gaps
Copyright AE Solutions 200651
Mapping SoftwareMapping Software
• The software that implements guidance is Micropack’s FDA and GDA custom software package.
• The process starts by converting a detector field of view picture into a “2 ½ D software footprint” taking account all obstructions shown in the photograph.
• This footprint is overlaid onto a ‘graded’ equipment layout
• The resulting coverage is assessed using the performance targets.
Grade Maps & AssessmentsGrade Maps & Assessments Notes : (Detection Scenarios)
1. The control and alarm target fires can be 'seen' by the flame detection system
2. Because the Grade B detection target requires an alarm to a smaller fire size it is possible for two detectors to respond to the 50Kw control action target while being unable to respond to a smaller 10Kw alarm fire target.
3. This case occurs when only one detector can 'see' the fire - two detectors are required for control action.
4. This case occurs when the detector is too far from the hazards to 'see' the specified target fire size. If the fire incident escalated then the detector will respond
5. No detector can see this hazard and there will be no response.
