Problem Identification and Resolution
The FPS-3 has designed-in troubleshooting tools to help you determine the cause of a problem and
make rapid repairs.
NOTE:
Portions of this procedure require the use of the Field Performance Analyzer
(FPA), the FPS-3 companion test set.
Problems can be generally divided into two catagories:
Problems that affect all zones or a group of zones. These problems can usually be traced to the
FPS-3 central controller or the MX-5300.
Problems that affect individual zones or two adjacent zones (i.e., two zones from one field-
mounted pre-amp. These problems can usually be traced to one field mounted pre-amp, the
sensor cable for that zone, or the cable running from the central controller to the pre-amp.
All troubleshooting should begin at the FPS-3 Central Controller. Follow this procedure to begin
troubleshooting:
NOTE:
Do not go to the fence mounted equipment before first checking the central
controller.
If you have a problem that is affecting all system zones or at least one group of adjacent zones,
proceed to Table 4 to isolate the problem to a component of the FPS-3 interface board.
•
Table 4 allows you to troubleshoot to the FPS-3 interface board integrated circuit compo-
nent level.
•
The FPS-3 interface board components are installed in plug-in sockets to facilitate easy
field replacement.
Open the FPS-3 central controller to gain access to the test functions.
Observe the red alarm lamps and the yellow tamper lamps on each FPS-3 zone receiver board.
•
A red alarm lamp indicates that an alarm is present at the fence. This problem can prob-
ably be traced to the field mounted preamp or the fence-mounted sensor cable.
•
A yellow tamper lamp indicates that a tamper is present at the field-mounted preamp. This
problem can probably be traced to a problem with the fence mounted sensor cable or
terminations.
Test the suspect zone(s) as follows:
•
Plug the audio test lead into the Local Audio connector located on the controller interface
circuit board.
•
Connect the audio test lead alligator clip to the suspect zone audio test point, TP1. See
Figure 52.
•
Using a small screwdriver set the Test Select switch, S3, to the Dual Zone Card being tested.
Note that the test select switch is marked with hexadecimal marking so the first zone is
one, the tenth zone is marked “A” continuing to the fifteenth zone which is marked “F.”
