LEDs with only one zone mapped
With only one zone mapped to an LED, a partial isolate state never occurs. The isolate LED
is on steady when the zone is isolated. With a "two column board", if the zone is not isolated
then the isolate LED indicates fault if the zone is in fault and is otherwise off.
LED Display board types and LED cadences
There are two types of LED display boards that can be connected to an RDU. One type of
board has two columns of LEDs (red and amber) and the other type has three columns of
LEDs (one red column and two amber columns). On the three column board, the red
column is used to display alarm states, the middle amber column displays fault states and
the outer amber column displays isolate states. On a two column board, the amber column
can be configured to show isolate states only, or the amber column can be shared by fault
and isolate.
Three column board LED cadences
1. Unacknowledged alarm - 2 Hz flash
2. Acknowledged alarm
- on steady
3. Fault
- on steady
4. Isolate
- on steady
5. Partial isolate
- 2.5 seconds on, 0.5 seconds off
6. Auto-reset mode (in-situ) - Isolate LED flashes at 2 Hz
Two column board cadences
1. Unacknowledged alarm - 2 Hz flash
2. Acknowledged alarm
- on steady
3. Fault
- 2 Hz flash
4. Isolate
- on steady
5. Fault and isolate
- 2 Hz for 1 second then 1.5 on, 0.5 off (2 short, one long)
6. Fault and partial isolate - 2 Hz for 1 second then 1 Hz for 2 seconds (2 short, 2 long)
7. Partial isolate
- 2.5 seconds on, 0.5 seconds off
8. Auto-reset mode (in-situ) - Isolate LED flashes at 2 Hz

OPERATION OF THE ZONE TO LED MAPPING MENUS
Zone to LED mapping allows programming the LED mapping for a zone or range of zones.
For a zone range, all zones in the range can map to the same LED or they can map to a
range of LEDs where the number of LEDs in the range is the same as the number of zones
in the range. E.g., a zone range of 1 to 5 (5 zones) can map to LEDs 17 to 21 (5 LEDs) or
they can all map to LED 17. The display always shows a start zone and an end zone, plus a
start LED and an end LED. When a single zone is being mapped, the start zone and end
zone are the same value. When a zone range is being mapped to a single LED, the start
LED number is the same as the end LED number.
NOTE 1
. If the PC appl
ication “PanelX” is being used, then the dedicated arrow keys on the
PC keyboard can be used as left/right arrow operations.
NOTE 2
. A database re-initialize operation assigns a default LED mapping which is that
zones 1 to 528 map to LEDs 1 to 528. If this default mapping is not what is needed, then
before entering new LED mapping data, it is probably easiest to first
delete the existing
mapping using the DELETE key.
This means that when you enter a new mapping, you
are not continually asked to confirm that you wish to replace the existing mapping.
