CORRECTIVE ACTION

3. J-SIIDS LEDA FLEX TERMINATION PWA FAILURE (FO-8)

Step 1. Check the power on lamp on the Leda Flex termination card. The lamp should be on.

If the lamp is on, go to Step 4.

If lamp is off, replace the termination card PWA (Para. 3-93).

If the lamp is still off, reinstall the termination card PWA and replace the Leda Flex PWA (Para. 3-92).

If the Leda Flex termination PWA is still showing a failure, go to Step 2.

Step 2. Using a multimeter, check for +12 vdc across TB8 pins 1 and 2.

If the voltage is present, replace the PWA. (Para. 3-93)

If the voltage is not present, go to Step 3.

Step 3. Using a multimeter, check for +12 vdc across TB-1 pins 2 and 3 on the Hinged Panel Assembly.

If voltage is present, replace wiring between TB-1 pins 2 and 3 and the Leda Flex Termination Board TB8 pins 1

and 2.

If voltage is not present, replace the J-SIIDS Regulator.

Step 4. 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. 3-93).
