Programming
5.7.4
Peripheral loop addressable NAC circuit controller units
•
Up to 15 4-way NAC cards can be added to the system via the 485 peripheral loop.
•
These NACs are programmed in the same way as the other NACs.
When shown on the display, the letter "P" appears in front of the address. This indicates the output is on the
peripheral bus. A letter is added after the address to indicate relay A, B, C or D.
•
When peripheral bus units are used, their zonal programming selection is shown by using the same "NAC"
option as the on board and loop driven outputs.
For example, a NAC circuit
controller SCC module wired
onto the peripheral bus with
an address of 11 may be
shown as :
•
This shows that all NACs wired into the output 'B' of the NAC circuit controller wired onto the peripheral bus
at address 11 will use ringing pattern 004.
An auto-learn must be performed on the peripherals before they will be added to the list of NAC
circuit outputs.
•
Refer to the 4-Way NAC Installation Guide further information.
•
Once commissioned any open or short circuits occurring on any of these inputs, either on-board or remote,
are automatically detected, recorded in the event log and displayed.
For example:

Relays
•
Most of the programming and functions of the relay outputs are the same as for the programmable NACs.
The exceptions are:
-
There is no circuit monitoring on any relay outputs and as such any open or short circuits occurring on
any external wiring can not be detected and is therefore ignored.
-
Unlike the programmable NACs, the relay outputs can not be programmed to pulse.
5.8.1
Fault Relay
•
The EN54 specification requires that a fault relay be permanently energized and de-energizes under fault
conditions. Relay No.1 is pre-programmed to function in this manner.
5.9
PC Programming
This configuration option allows a PC connected to the serial port to control the panel for uploading and
downloading panel text and configuration details. It is possible to prepare or alter installation information using
an IBM compatible PC and upload the data from a portable PC into the panel. This is particularly convenient
when large amounts of text, or complex ringing patterns are required. In this way, a backup copy of the site
configuration can be kept to allow rapid reprogramming if required. Refer to the PC programming manual for
details.
