Page 5: Introduction
Introduction Introduction The Wiegand Interface Unit-Four State (WIU-4) board features a Wiegand to F/2F data converter, which can accommodate both conventional and proprietary Wiegand reader protocols, and includes an 8 Amp relay for door strike control (entrance/exit) activity. It provides the communications interface that enables support of up to 16 Wiegand-output readers. -

Page 14: J3: Door And Rex Switch Connector
If the door or REX switch is set up as supervised (1K resistor in series with switch between high and return pins, 1K in parallel with switch), the WIU-4 treats both the door and REX switch as supervised and reports four states: cut line, short circuit, closed circuit, and open circuit. -
Page 15: J5: Reserved
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. -
Page 16: J7: Tamper Switch Connector
Installation Manual J7: Tamper switch connector The 2-pin connector, J7, can be used to connect a tamper switch to protect the enclosure in which the WIU-4 is mounted. To activate this feature, connect a single-pole, single-throw (SPST), normally-open push button switch (installer supplied) to connector J7 on the WIU-4 and install the switch in the desired position. -
