This allows extremelysensitive Pre-Alarm capability with reasonable protection against non-fire signals.Figure 81 shows a graphical representation of the Self-Optimizing Pre-Alarm level:)LJXUH 6HOIRSWLPL]LQJ 3UH$ODUP /HYHOFor more information on setting Pre-Alarm levels, refer to the following sections:• "How to Change Sensitivity for a Detector" on page 41• "How to Use the Detector Sensitivity Screen" on page 41'HWHFWRU6HQVLWLYLW\/HYHOVThe control panel provides nine Sensitivity Levels for alarm detection and pre-alarm asfollows:1RWH )RU D OLVW RI DOO GHWHFWRUVHQVLWLYLW\ OHYHOV VHH 7DEOH RQ SDJH • Alarm Sensitivity Levels You can select the sensitivity of a detector from 1-9(1=highest sensitivity; 9=lowest sensitivity).• Pre-Alarm Sensitivity Levels You can select one of nine levels from 1 to 9 (0=noPre-Alarm, 1=self-optimizing, 2=highest sensitivity, 9=lowest sensitivity). You canset Pre-Alarm operation to Action (latching) or Alert (non-latching) and to activateSpecial Zones. For instructions on programming, refer to "How to Select aPre-Alarm Level" on page 78.You can set the sensitivity levels as fixed or programmed for day and night operation.For details, refer to"Time Control Zones" on page 71.Figure 82 shows a sample sensitivity window for a laser detector:)LJXUH 6HQVLWLYLW\ /HYHOV IRU D /DVHU 'HWHFWRUTechnical Manuals Online! - http://www.tech-man.com
