9.4 IQ 8-Reader Expansion Module (P/N: 03-10102-201E)
The IQ-400 4-reader system can be expanded to a 12-reader system by installing the 8-Reader
Expansion Module. The 8-Reader Expansion board can be mounted below the IQ-400 in the
larger enclosures available from PCSC. Once mounted, the 8-Reader Expansion board is
connected to the IQ-400 by installing a 50-pin ribbon expansion cable from P1 on the 8-reader
Expansion board to J1 on the IQ-400.
The 8-Reader expansion board allows the user to connect up to 8 additional readers to the IQ-
400. Each of the reader interfaces support either a PCSC proprietary reader (4-wire interface), or
a Wiegand reader (5-wire interface). The Expansion board also provides 8 additional interfaces
for each of the readers and the associated doors. These include the following:
• Multilevel Door Sense Inputs (Supervised door sense inputs)
• Reader Present inputs (Reader connected/disconnected)
• Request to Exit inputs (Supervised Egress Inputs)
• Relay contacts for door control outputs (Form C dry contacts rated for 2.0 Amps @
12/24VDC continuous power)
• Door shunt/Local Alarm/Outputs (Open Collector output rated for +12 VDC @ 100mA)
9.4.1 Power Supply
The 8-reader Expansion Module requires +5VDC for all logic. Relays, output drivers, etc. require
a +12VDC supply. The +5VDC and +12VDC is provided to the module via the 50-pin expansion
cable, which connects plug P1 of the 8-door cluster PCB (P/N 03-10102-201E) to plug J1 of the
IQ-400 board, (P/N 03-10111-201). The Variable Ambient Test will be for Indoor, 0 to 49 Degrees
C, and 85% Relative Humidity @ 30 Degrees C.
9.4.2 Door Sense LEDs
8 LEDs located at D17, D18, D19, D20, D21, D22, D23, and D24 indicate the status of the Door
circuits. Resistors must be installed at the door contacts, the switches in place, door closed
(normal state), and the lines calibrated, in order for the supervised inputs to function. See Section
2.2.5.1.2 [Proper Point by Point Calibration] of the LiNC-NET Administrator Guide (P/N: 38-
10055-001) for calibration procedure.
