SYSTEM CONFIGURATION MENU
The System Configuration menu is shown in Figure 6.1.4. section 6.1.
1:Modules 2:Output Logic 3:Outputs 4:Zone config 5:Zone LED mapping
Output logic is described in section 7.3. Zone config is described in section 7.2. Zone LED
mapping is described in section 7.7.1. Option 3 Outputs allows programming of options for
the ancillary relays on the MAF board and is described in section 7.4.2.
CONFIGURING MODULES
1:MAF Board 2:LED Display bds 3:MAX LEDs on 4:Display board type
Option 1 (MAF Board) allows selecting whether a MAF board is installed.
Option 2 (LED Display bds) allows setting the number of zone LED display boards (0 - 33)
that are connected.
Option 3 (MAX LEDs on) allows setting the max number of zone LEDs that can be on
simultaneously. This is to limit the maximum current that is used driving LEDs. The default
value is 240 and the maximum value is 240.
Option 4 (Display board type) allows configuring the type of each LED display board. LED
boards are configured in ranges. Enter the first board (1-33) and the last board (1-33) in the
range to be configured. Board number 1 corresponds to the board that is furthest from the
controller board, i.e., is at the end of the chain of display boards. Board number 1 has LED
sets 1 to 16 and board number 33 has LED sets 513 to 528. The following options can be
configured for each board.
1:Share Iso/Fault 2:LED Columns 3:Relay type board
A two column board has two columns of LEDs; a red column (for alarm) and an amber
column (for fault/isolate). A three column board has a red column and two amber columns.
The outer-most amber column indicates an isolate state and the inner-most amber column
indicates fault.
Option 1 (Share Iso/Fault) allows the selection of whether the amber isolate/fault LED should
be shared between fault and isolate. On a "two column" board, the amber LED is normally
shared and on a three column board it is normally not shared.
Option 2 (LED Columns) allows the selection of whether the board is a 2 column or 3 column
type.
Option 3 (Relay type board) allows selection of whether the board has relays on it. For a
board that is configured as "relay type", the alarm LEDs never flash and the board is not
tested during an LED display test.
LED Phasing
When phasing occurs, six boards at a time show the correct state of their LEDs and the
other boards are all off. Every 3 seconds, the "window" moves by one position. Hence a
minimum of seven boards must be present for any phasing to occur. Any boards which are
programmed as "relay type" will always show their true state.
