D.2.3 Self-Optimizing Pre-Alarm
You can set each detector, except 5351J (Heat), for Self-Optimizing Pre-Alarm (PA=1). In this Self-
Optimizing mode, the software measures the normal peak analog readings and sets the Pre-Alarm
level just above these normal peaks. This allows extremely sensitive Pre-Alarm capability with
reasonable protection against non-fire signals. The figure below shows a graphical representation
of the Self-Optimizing Pre-Alarm level:

D.2.4 Detector Sensitivity
The control panel provides nine Sensitivity Levels (Table D.2 on page 120) for alarm detection and
pre-alarm as follows:
• 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=no
Pre-Alarm, 1=self-optimizing, 2=highest sensitivity, 9=lowest sensitivity). You can set
Pre-Alarm operation to Action (latching) or Alert (non-latching) and to activate Special
Zones. For instructions on programming, refer to “Pre-Alarm” on page 118.
You can set the sensitivity levels as fixed or programmed for day and night operation. For details,
refer to “Coding Functions for Panel Circuit Outputs” on page 114.
