3. LEDA FLEX TERMINATION PWA FAILURE (continued)
Step 4. Using a multimeter, check for +12 v across TB1 pins 3 and 4 on the RADC Stargate PWA.
If voltage is present, replace wiring between TB1 pins 3 and 4 on the Stargate PWA and TBK pins 3 and 4 on the
RADC rear panel assembly.
If voltage is not present, replace the Stargate PWA. (Stargate 5000, Para. 3-38 and Stargate 1000, Para. 3-48)
Step 5. Make a visual inspection of the 12 LEDs (lamp indicators) on the Leda Flex Termination PWA. The LEDs
should be out, unless a sensor is in alarm or tamper (open or short). When the LED is red, the sensor is in alarm.
When the LED is green, the sensor is in tamper short. When the LED is amber (red & green), the sensor is in tamper
open.
If any of the LEDs are lit, remove the wire(s) to the input terminal(s) of the terminal board for the LED that is lit.
The LED should change to amber (tamper open).
If the LED does not change to amber or stays in amber, replace the termination card PWA (Para. 3-43).
Step 1. Using a multimeter, check for +5 vdc across TB2 pin 5 (black lead) and TB1 pins 1 through 8 and TB2 pins 1
and 2 (for microphone 1 through 10). The multimeter should indicate +5 vdc on the terminal board connector pin for
the microphone that has been turned on.
If +5 v is not present when either of the above occurs, replace the Audio Assessment Controller (Para. 3-41).
If the +5 vdc is present all the time, replace the Audio Assessment Controller (Para. 3-41).
