5.9 UCS
Configuration
As a security precaution, the A704-5 lights have a five-minute window from the push
button press to listen for the UCS. If the UCS is transmitted after the five-minute
window, the A704-5 light UCS will ignore the controller’s UCS command and will not
flash. Follow directions to initialize that light.
Configuring an airfield system for UCS will normally involve the following operations:
Initialization: generate the UCS in the wireless controller and lights
Adding: add one or more lights to an existing UCS configuration
Re-keying: transmit a new UCS to the airfield lights
Removal: remove the UCS in the wireless controller and lights
Reception: transmit the UCS to another wireless controller
The wireless controller can only store one UCS at a time. A UCS will be overwritten
with a new one in the following circumstances:
A Generate UCS operation is performed and it is followed immediately by a
Transmit UCS operation
A Remove UCS operation is performed and it is followed immediately by a
Transmit UCS operation
A Receive UCS operation is performed and a UCS is transmitted from another
controller
There is no way to retrieve a UCS once it has been removed or overwritten, so it is recommended the
UCS be transmitted to a backup controller.
Initialization
Both the wireless controller and A704-5 light arrive from the factory with UCS removed. Complete the
following steps to initialize an airfield with a UCS:
1. If not already in Administrator Mode, put the controller into Administrator Mode; see section
5.4.2
Administrator Mode
.
2. Generate a new UCS using the controller (7, ENTER, see section
5.8.3 Unique Code Sequence
(UCS) Management
).
3. Put the controller into Transmit UCS Mode (9, ENTER, see section
5.8.3 Unique Code Sequence
(UCS) Management
).
4. Press the push button on the A704-5 light(s).
5. Transmit the UCS by pressing the ENTER button on the wireless controller, see section
5.8.3 Unique
Code Sequence (UCS) Management
Unique Code Sequence (UCS) Management.
The A704-5 light(s) will flash for five seconds to indicate acceptance of the UCS.
6. When all lights have been initialized, press the CLEAR button on the wireless controller to exit
Transmit UCS Mode.
If the lights are already deployed on the airfield, it may be easier to initialize a small set
of lights at a time. To do this follow steps 1-5 for the first set and then follow steps 4-5
for each additional set.
Adding a Light to a UCS System
Adding allows additional lights to be included in an existing UCS configuration.
