Powering up the Network Access Controller
In case the Network Access Controller will be connected to a ChallengerPlus
panel
• Ensure the ChallengerPlus system LAN is connected to the Panel
terminals (Figure 2 on page 12, item 9)
• Ensure the Network Access Controller’s address is set. (Refer to DIP
switch settings on page 11).
Ensure that jumpers on board are set correctly and that TEST LINKS are not
fitted.
After power-up, check the Heart Beat LED (Figure 2 on page 12, item 30). See
LED indicators on page 29.
Note: Devices connected to the RS-485 buses and powered by the Network
Access Controller must comply with Appendix B: Output fusing and user current
limits on page 34.
Refer to the TS1067E Network Access Controller Programming Manual for
information on configuring the Network Access Controller.
Defaulting the Network Access Controller
You may want to perform a “default” to reset the Network Access Controller to its
factory default state and erase all programming.
To default the Network Access Controller:
1. Remove power to the Network Access Controller and wait for all LEDs to
turn off.
2. Fit test link 1 (Figure 2 on page 12, item 29) and repower the system. The
Heart Beat LED (Figure 2 on page 12, item 30) illuminates for about 20
seconds, flashes quickly for about 20 seconds to indicate reset mode, and
then flashes slowly to indicate normal mode.
Note: The Network Access Controller can only be defaulted in the
20-second interval when the Heart Beat LED is flashing quickly (in reset
mode). The Network Access Controller returns to normal mode
automatically to help protect against accidental reset.
3. Remove test link 1 when the Heart Beat LED is flashing quickly to default
the Network Access Controller.
