AWACS ™ (Advanced Warning Addressable Combustion Sensing) is a set of software
algorithms that provide the AFC-600 with industry-leading smoke detection capability.
You can program AWACS functions on a global or on a per-detector basis as listed in
Table 37, which lists the AWACS topics covered in this appendix:

AWACS features include the following:
• Drift Compensation and Smoothing
• Maintenance Warnings
• Sensitivity Adjust
• Self-optimizing Pre-Alarm

Drift compensation uses algorithms (U.S. patent pending) 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 the periodic sensitivity measurements required by NFPA Standard 72.
AFC-600 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 “Detector Sensitivity
Settings” on page 79 for more information on detector sensitivity levels.
