6.4.2.9 SEAR IIi Alarms
Alarm Generation is the final step in checking out the SEAR IIi/WAMS interface. The following
procedure tests the wiring of the various components in the SEAR/ WAMS sub-system.
Ground Fault Alarm
•
A ground fault can be simulated on those inputs by running a wire from the ground
input of the GFT to each BAT input, one at a time.
•
Each Battery’s LED will flash when a ground fault is detected and a “Ground Fault
Detected on xxx” alarm will be generated where xxx represents the Battery name.
Ground Fault Clear
•
Removing the wire that simulates the ground will generate a Ground Fault Cleared
message.
Analyzer Failure Alarm
•
Remove the connector that powers the GFT or that MTSS unit inside the gate
mechanism. Doing so on either unit will cause an “Analyzer Failure” alarm.
Analyzer Normal
•
Restoring the connector will generate an Analyzer Normal message.
WARNING
TAKE ALTERNATE MEANS TO WARN VEHICULAR TRAFFIC,
PEDESTRIANS, AND EMPLOYEES. REMOVAL OF A SSCC IIIi WILL
CAUSE GATES TO DESCEND IMMEDIATELY (WITHOUT GATE DELAY),
HOWEVER, THE LIGHTS WILL NOT ACTIVATE.
Crossing Controller Failure Alarm
•
Temporarily remove an SSCC IIIi to generate a Crossing Controller Failure alarm
•
Restore SSCC IIIi for a Crossing Controller Normal message.
False Detection Alarm
•
Activate the crossing using a test switch (or other method shown on plans) allowing
the gates to drop and then cancel the activation.
•
After 30 minutes a False Detection alarm will be generated.
•
If a normal train move occurs before the 30 minutes, a Pre-Ring alarm will be
generated.
AC Power Off For 20 Minutes Alarm
•
Turn off AC power for at least 20 minutes and this alarm will be generated.
•
AC Power Back On
•
Restore power and wait at least 1 minute.
This completes the SEAR IIi operational tests.
