Appendix C: Intelligent Sensing Applications
C.1 Intelligent Sensing Overview
Intelligent Sensing is a set of software algorithms that provide the AFP-3030 with industry-leading
smoke detection capability. The user can program Intelligent Sensing functions on a global or on a
per-detector basis.
Intelligent Sensing topics covered in this appendix:
C.2 Intelligent Sensing Features
Intelligent Sensing features include the following:
• Drift Compensation and Smoothing
• Maintenance Warnings - Three Levels
• Self-optimizing Pre-Alarm
• Detector Sensitivity
• Cooperative Multi-Detector Sensing
C.2.1 Drift Compensation and Smoothing
Drift compensation uses algorithms that identify and compensate for long-term changes in the
analog readings from each smoke detector. (Typically, dirt and dust accumulation inside the smoke
chamber causes long-term changes in detector readings.) Drift compensation does the following:
• Allows a detector to retain its original ability to detect actual smoke, and resist false alarms,
even as dirt and dust accumulates.
• Reduces maintenance requirements by allowing the control panel to automatically perform
periodic sensitivity measurements.
The software also provides smoothing filters to remove transient noise signals, usually caused by
electrical interference. Different smoothing algorithms are used, depending on the sensitivity
selection of each detector. Refer to
Appendix C.4, “Detector Sensitivity Settings”, on page 107 for
more information on detector sensitivity levels.
