Connecting a Cisco Input Module
Overview
The optional Cisco Input Module (Figure 4-1) is attached to a Cisco Physical Access Gateway or Cisco
Reader Module to provide additional connections for up to ten input devices. Each connection can be
configured as supervised or unsupervised. A supervised connection is a four- state connection to
determine if the connection is (1) short (2) is open (3)normal state or (4) alarm state. An unsupervised
input indicates only normal or alarm.

Type Description
1Power Two-pin connector for Voltage In (VIN) and Ground (GND) to
connect a 12 to 24 VDC external power source.
2CAN interface A 3-wire CAN bus is used to connect additional modules.
Note Modules are connected using the CAN1 interface. The
CAN2 interface is not supported in this release.
3CAN Terminator The CAN terminator switch is set to ON for the last device in a CAN
wiring bus. This switch is set to set to OFF for all other devices in
the CAN bus.
4Input connections Ten input interfaces used to sense the contact closure. Each input
can be configured as supervised or unsupervised and can be
configured to sense a Normally Open (NO) or Normally Closed
(NC) contact.
•An unsupervised input senses a simple contact closure state,
including Normal or Alarm. When connected to open contacts,
the terminal voltage range is 4V to 5V. For closed contacts, the
voltage range is 0V to 0.7V.
•A supervised input senses four contact states, including
Normal, Alarm, Open and Short. These inputs require 1K
End-Of-Line (EOL) termination resistors installed at the
contacts (two resistors are included in the accessory kits for
each Input port).

Installing the Cisco Input Module
Status LEDs
Each input port includes a status LED that indicates the following information:
Installing the Cisco Input Module
Install a Cisco Input Module is provide additional input connections for a Cisco Reader Module or
Gateway
Before You Begin
Verify the following:
•Verify that the module has access to a power source. See Power Options and Requirements,
page 1-10 for more information.
•Verify that you have the necessary mounting brackets or other hardware. See Mounting a Gateway
or Optional Module, page 1-12.
Installation Procedure
To install the module, perform the following procedure:
Step 1 Mount the module to a wall. See Mounting a Gateway or Optional Module, page 1-12 for more
information.
8PF Power fail input: an unsupervised input that raises a “power fail”
alarm when the circuit is open. Can be configured as an additional
unsupervised port. The corresponding LED is red when circuit is
open (when no input is connected).
9TM Tamper input: an unsupervised input that raises a “tamper” alarm
when the circuit is open. Can be configured as an additional
unsupervised port. The corresponding LED is red when circuit is
open (when no input is connected).

Installing the Cisco Input Module
Step 2 Connect the module to the DC power source:
a. Insert a two-pin connector plug into the DC power port (Figure 4-5)
b. Connect the Voltage In (VIN) and ground (GND) wires.
See Power Options and Requirements, page 1-10 for more information.
Figure 4-5 Power Connections for the Input and Output Modules
The following items are shown in Figure 4-5:
Step 3 Connect the module to the CAN bus:
a. Insert a three-pin connector plug into the CAN1 port, as shown in Figure 4-6.
b. Connect the CAN wires to the CAN bus, as shown in Figure 4-7
c. Turn the CAN terminator ON if the device is the last device in a CAN wiring bus.
Note The CAN terminator switch in included on the Reader, Input and Output modules only (the Gateway is
always the first device in the CAN bus). Set the terminator switch to OFF for all other modules in the
CAN bus.
Note The CAN2 interface is not supported in this release.
See Optional Expansion Modules, page 1-6 for more information.

c. Connect the wires from the input devices.
Note Each of the input connections can be configured as supervised or unsupervised. The tamper
(TM) and power fail (PF) inputs can be configured as additional unsupervised ports. A
supervised input supports four states: normal, alarm, open and short. An unsupervised input
indicates only normal or alarm.
