MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
4. SWIPE CARD READER FAILURE (FO-9)
Step 1. View the Proceed, Wait, and Error LEDs on the swipe card reader. The LEDs should be extinguished.
If the LEDs are out, go to step 2.
If any of the LEDs are on, replace the swipe card reader (Para. 3-110).
Step 2. Using a known good access swipe card, slide card through the swipe card reader. The Proceed LED
should illuminate to allow access or exit to and from the secure area. The Wait LED will illuminate if
someone is entering or exiting from the opposite side.
If the Proceed LED illuminates, the swipe card reader is operational.
If the Proceed LED does not illuminate, go to step 3.
Step 3. Remove the swipe card reader front cover and check the dc input voltage at fanning stripe, pins 5 and
6. The multimeter should read +12 v.
If voltage check is good, replace the swipe card reader (Para. 3-110).
If voltage is not present, go to step 4.
Step 4. Remove the IAC front panel and check for +12 v across TB7, pins 1 and 4 for the entry reader or TB8,
pins 1 and 4 for an exit reader.
If voltage is present, replace the wiring between the IAC PWA, TB7 pins 1 and 4 or TB8 pins 1 and 4
and the entry or exit swipe card reader.
