3 An alarmor other abnormal condition is determined by comparingthe sensor s present value against its average Data Evaluation. Monitoring each sensor saverage value provides a software filtering averagingprocess that compensates for environmental factors (dust,dirt, etc.) and component aging, providing an accuratereference for evaluating new activity. The result is asignificant reduction in the probability of false ornuisance alarms caused by shifts in sensitivity, either upor Panel Selection. Peak activity per sensor isstored to assist in evaluating specific locations. The alarmset point for each TrueAlarm sensor is determined at thecontrol panel, selectable as more or less sensitive as theindividual application Selection. Alarm set points can beprogrammed for timed automatic sensitivity selection(such as more sensitive at night, less sensitive duringday).

4 Control panel programming can also providemulti-stage operation per sensor. For example, a may cause a warning to prompt investigation while level may initiate an Alarm and Trouble LED Indication. Thecontrol panel determines when individual sensors needcleaning. Dirty sensors, or other sensor trouble, willautomatically be annunciated at the control panel and thatsensor s base LED will light steadily. In an alarmcondition, the alarmed sensor s LED will light steadily.(LED operation is controlled by the panel. During asystem alarm, a sensor LED steady on to indicate atrouble may return to pulsing to conserve communicationspower.)
