16 and 24 Zone
GRX Control Units
GRX-4116/4516 and GRX-4124/4524 Control
Units
The 16 and 24 zone GRAFIK Eye Control Units offer an
expanded number of zones that can be controlled from a single
wall station. The zone intensity LEDs on the GRX-4x16 or GRX-
4x24 will display the light level of eight zones at a time. Other
sets of zones may be displayed and controlled by pressing the
Zone Select Button.
Addressing
The GRX-4x16 and the GRX-4x24 Control Units take multiple,
consecutive addresses. The GRX-4x16 Control Unit takes up two
consecutive addresses, and the GRX-4x24 Control Unit requires
three. To ensure there are sufficient addresses available, any
GRX-4x16 and/or GRX-4x24 Control Units in the system should
be addressed first.
Assigning Zones
When assigning zones use the chart on the right as
a guide to see how zones are displayed on the Circuit Selector.
T
Note:
he chart at right is for a GRX-4x24, which uses three
addresses. A GRX-4x16 will have two addresses.
