False Dispatch RateAlarm Factor
Before False Dispatch Reduction
100,000 Dispatches
500 Actual alarms
99,500 False alarms
99,5000 /100,000
= 99.5% False
After False Dispatch Reduction
10,000 Dispatches
500 Actual alarms
9,500 False alarms
9,500/10,000
=95.0% False
Use the alarm factor (# of false dispatches/ # of alarm systems) to determine the impact of false dispatch prevention not the false dispatch rate.

Use Alarm Factor, Not False Alarm Percentage
Alarm Factor = # of False dispatches # Of alarm systems
Remember to always
use the Alarm Factor
