The Calibrate tool
Use the Calibrate tool to see the effects of Gain and Filter adjustments before changing the
processor’s settings. First, make the changes using the calibrate tool. Then, view a magnitude or
frequency response plot using the new settings while testing the installation. If the changes do not
result in the required level of detection, continue making and reviewing adjustments. When the
results are satisfactory, download the new parameters to the processor.
CAUTION
Some of the UCM parameters are available through the Advanced
parameters view and should be adjusted only by qualified personnel.
Note
Consult the online help for additional details on UCM operation.
Note
An enclosure tamper condition must exist to establish a UCM
connection to the FlexPI processor (enclosure cover - OFF, tamper
switch lever - UP, shunt not installed on T3, D17 DOOR LED - ON).
