6.3.4 Auto Calibration
The auto calibration feature is designed to allow compensation for the
resistance tolerances in the two legs of the sensing wires.
As soon as cable is connected, the panel begins calculating the cable
length. Initiating the auto calibration feature allows the user to mod-
ify the distance to account for any discrepancies. Once the new dis-
tance is entered, the panel adjusts for the required offset between the
calculated value and the user value.
To initiate automatic calibration for ZN1:
• From the Setup Zone 1 Menu, choose Auto Calibrate, as shown
at right, and press Enter ↵.
• At the Change Maximum Length screen, you may change the
maximum length of cable protecting this zone:
• To begin calibration without changing this value, press
Enter ↵.
• To change the value, press and hold one of the arrow keys
↑↓
to scroll through the numbers, then press Enter ↵.
• The next screen displays the progress of calibration.
6.3.5 Set Up Sensitivity for Water Detection
Each zone may be set up with a sensitivity level at which water is
detected.
• The most sensitive setting is 25 µA—minimal water is required to
trigger an alarm.
• The least sensitive setting is 300 µA. At this setting, the cable will
be submerged in water for a longer period before an alarm is trig-
gered.
To change the setting:
• From the Setup Zone 1 Menu, choose Water Detect, as shown at
right, and press Enter ↵.
• The Water Detection Sensitivity screen displays the value for
detection of water (in the example at right,
150 UA, where UA rep-
resents µA or microAmps):
• To change the value, press and hold one of the arrow keys
↑↓
to scroll through the numbers 25-300.
• Press Enter ↵.
