Configuring the WIU-4

J5: Reserved
The 3-pin connector, J5, is reserved. A jumper must be
installed across pins 1 and 2.
J6: Reader interface connector
The 10-pin connector, J6, is the reader interface connector.
If a tamper switch is desired, connect a single-pole, single-
throw (SPST), normally-closed push button switch (installer
supplied) to connector J6, pins 8 and 9 on the WIU-4. When
used with a Micro/5-PX, Micro/5-PXN, M5PXNplus, Micro/
PX-2000, Micro/PXN-2000, M2000PXNplus, or
M3000PXNplus, the WIU-4 sends a supervised reader
alarm message.
