AWACS Overview $SSHQGL[ & $:$&6 $SSOLFDWLRQVAFC-600 Programming PN 51032:A 3/8/99 73$SSHQGL[& $:$&6$SSOLFDWLRQV$:$&62YHUYLHZAWACS™ (Advanced Warning Addressable Combustion Sensing) is a set of softwarealgorithms 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 inTable 37, which lists the AWACS topics covered in this appendix:7DEOH $:$&6 7RSLFV$:$&6)HDWXUHVAWACS features include the following:• Drift Compensation and Smoothing• Maintenance Warnings• Sensitivity Adjust• Self-optimizing Pre-Alarm• Cooperative Multi-Detector Sensing• Pre-Alarm'ULIW&RPSHQVDWLRQDrift compensation uses algorithms (U.S. patent pending) that identify and compensatefor long-term changes in the analog readings from each smoke detector. (Typically,dirt and dust accumulation inside the smoke chamber causes long-term changes indetector readings.) Drift compensation does the following:• Allows a detector to retain its original ability to detect actual smoke, and resistfalse alarms, even as dirt and dust accumulates.• Reduces maintenance requirements by allowing the control panel to automaticallyperform 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 SensitivitySettings” on page 79 for more information on detector sensitivity levels.Continued on the next page...Topic Refer to PageAWACS features – Descriptions of AWACS features, such as DriftCompensation, Sensitivity Adjust, programmable on a per-detectorbasis.73Pre-Alarm – Alert and Action settings, programming (global settings). 78Detector Sensitivity Settings – Pre-Alarm and Alarm sensitivity settingsfor photo, ion, laser, and multisensor detectors programmable on a per-detector basis.79Detector Maintenance Features – Instructions for viewing and printingdetector maintenance information.81Technical Manuals Online! - http://www.tech-man.com |
