In Figure 10, the violet wire (open collector output) can be connected to an
input via a 10K resistor to operate as a tamper input (refer to the reader’s
installation guide for details).
Note: Figure 10 shows the cable provided with TS0870 Smart Card
Readers. Other Wiegand readers may be connected using 6-core
shielded data cable (Belden 9536 or equivalent).
Connecting expansion modules
Note: The TS1067E board must be powered down when connecting or
disconnecting the input or relay expansion modules.
Input expansion
The Network Access Controller can accommodate two TS1021 8 way input cards
to allow up to 32 onboard inputs on the device. The TS1067E comes with inputs
1-16 already included in the board. To utilise inputs 17-32, the input expanders
will need to be properly addressed and polled. For example input expander
address 2 will be assigned the input range 17-24 and input expander address 3
will contain inputs 25-32.
Note: The input expander cannot be addressed as 1 when connected to the
NAC. This will cause a conflict with the onboard inputs 9-16.
Relay expansion
The Network Access Controller has four onboard relays that are assigned the
first four relay numbers.
If relay expansion cards are used, additional relays are numbered according to
their physical address, starting at 5. The Network Access Controller allows for
relay mapping to be programmed such that a physical relay number (e.g. 5) can
be mapped to a relay number in the ChallengerPlus system (e.g. 21).
One TS0840 Four-Way Relay Card may be connected to the Relay Expander
(Figure 2 on page 12, item 34) to add four relays. Alternatively, TS1041
Eight-Way Clocked Relay Expansion Boards or TS1042 16-Way Clocked Open
Collector Expansion Boards may be connected to the Relay Expander
individually or daisy-chained to add eight relays per card (for TS1041) or 16 open
collector outputs per card (for TS0842).
Note: If TS1041 and/or TS0842 boards are used, then a value for Relay
Controllers must be programmed for the Network Access Controller in CTPlus,
where 1 represents each eight relays or open collector outputs. Refer to the
TS1067E Network Access Controller Programming Manual or CTPlus online help
for details.
The test link 3 (Figure 2 on page 12, item 29) acts as an input that enables the
Network Access Controller to output power to a connected relay expansion
module. Remove the link if the relay card is powered from an external 12 V
