8.1 Alarm Factor
The detector calculates sensitivity relative to the ambient environmental conditions. Higher Alarm Factors
provide reduced sensitivity (the Alarm threshold is maintained further away from the ambient level). Refer
to the Remote Software manual for further details.
NOTE: Changing the Alarm Factor starts a new FastLearn cycle: during the initial 15 minute learning
period, the detector is incapable of reporting an alarm. The unit will take 24 hours to achieve
optimum performance, based on the ambient conditions.
8.2 ClassiFire
®
Enabled
Allows the artificial intelligence system to continuously adjust Alarm thresholds in order to avoid unwanted
Alarms from environmental changes (recommended).
NOTE: Enabling this feature means that nuisance alarms due to fluctuations in the ambient environment
become less likely.
