C.4.1 How to Select Pre-Alarm and Alarm Sensitivity
Each detector provides a host of selectable intelligent options. The control panel provides nine
levels of Pre-Alarm (PA:1–PA:9) and Alarm (AL:1–AL:9) in percent per foot obscuration:
• PA:0 no Pre-Alarm selection.
• PA:1 usually the self-optimizing setting where the control panel selects a suitable
Pre-Alarm level for a detector.
• PA:2–PA:9 the detector Pre-Alarm sensitivity level - with PA:2 the most sensitive and PA:9
the least sensitive.
• AL:1–AL:9 the detector Alarm sensitivity level - with AL:1 the most sensitive and AL:9
the least sensitive.
NOTE: (d) Signifies the factory default setting in Table C.2.
