9.2 IQ 4-Reader Expansion Module (P/N: 03-10102-301E)
The IQ-400 4-reader system can be expanded to an 8-reader system by installing the 4-Reader
Expansion Module. The circuit board (Part # 03-10102-10X) can be mounted below the circuit board in
the larger enclosures available from PCSC. Once mounted, the circuit board is connected to the IQ-400
by installing a 50-pin ribbon expansion cable from P1 on the 4-reader module to J1 on the IQ-400.
The 4-Reader Expansion Module allows the user to connect up to 4 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 Module also provides an additional 4 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 (Unsupervised egress inputs)
•
Relay contacts for door control outputs (Form C dry contacts rated for 2.0 Amps @
12/24VDC continuous power)
•
Door shunt outputs (Open Collector output rated for +12 VDC @ 100mA)
•
Door Shunt/Local Alarm
9.2.1 Electrical Ratings
Power: 12VDC
Draw: 160mA @ 12V
Relay Contacts 2 A @ 24 VDC
Data0/Data1 5 Vdc @ 0 mA for Logic 1
0 Vdc @ 5mA for Logic 0
Card Reader Draw: 100mA @ 12 VDC
Alarm Point Voltage 5.0 Vdc @ 0.0 mA when Sense Input is in Open Circuit Physical State.
& Tamper Voltage 0.0 Vdc @ 5.0 mA when Sense Input is in Short Circuit Physical State.
1.6 Vdc @ 3.4 mA when Sense Input is in Alarm Physical State.
0.9 Vdc @ 4.1 mA when Sense Input is in Normal Physical State.
9.2.2 Power Supply
The 4-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 4-door cluster PCB (P/N 03-10102-301E) to plug J1 of the IQ-400 board,
(P/N 03-10111-201).
