Description
The GRX-CCO-8 provides eight dry contact closure outputs that integrate the control of customer-
supplied audio/visual equipment to
GRAFIK Eye
®
(GRX) Control Units. In addition, the GRX-CCO-8
can control Motorized Window Treatment (MWT) controllers that accept dry contact closures as
inputs.
The GRX-CCO-8 may operate in one of two control methods: Scene Control or Zone Control. In
Scene Control, the GRX-CCO-8 is assigned to one or more GRX Control Units, and a single output
is closed when the corresponding GRX Control Unit scene is selected. Only one output may be
closed at any given time.
In Zone Control, one or more GRX-CCO-8 outputs are assigned to a zone on a GRX Control Unit.
Different GRX-CCO-8 outputs may be assigned to zones on different GRX Control Units. A GRX-
CCO-8 output is opened or closed based on the intensity of the GRX Control Unit zone to which it
is assigned. To control MWTs, operate the GRX-CCO-8 in Zone Control.
Note:
If the GRX-CCO-8 is to control Motorized Window Treatments, use one of the following
GRAFIK Eye model numbers: GRX-350X-X-XX-CPN1622, GRX-450X-X-XX-CPN1623
Features

The GRX-CCO-8 provides both normally open (NO) and normally closed (NC) contacts.
■
The GRX-CCO-8 may be set to momentary or maintained outputs.
■
In Scene Control, the outputs may be associated with different GRX scene ranges.
■
In Zone Control, the outputs may be set as individual outputs or MWT channels.
