Configuring the WIU-4 11
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 pushbutton 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.
