Line Survey
If you determine that one or more stations are not working properly,
then before going into the field to address the issue you can take steps
at the controller starting with a Line Survey.
Calculate System Amperage
For the Line Survey it’s helpful to know what the total (approximate)
amperage for your system should be. This can be estimated using the
following formula:
System Amperage Calculation
Quantity of single address station decoders
X
0.5 mA
+
Quantity of multiple address station decoders
X
1.0 mA
+
Quantity of active decoders
X
17.5 mA
+
Quantity of other SD210 decoders
X
8.0 mA
=
Approximate total system amperage (in mA)
*
Single address station decoders include the FD-101 & FD-102 decoders
**
Multiple address station decoders include the FD-202, FD-401 & FD-601 decoders
Run a Line Survey
Once you have calculated the approximate amperage for your system,
use the following steps to perform a line survey for your system:
b
g
Turn the controller dial to Test All stations/Check System.
A
The System Diagnostics screen appears. Press the Down Arrow
button to select 2-Wire Diagnostics; then press Next.
B
The 2-Wire Diagnostics screen appears. Press the Down Arrow
button to select Line Survey; then press Next.
