Green Light Power Switching Crestron Commercial Lighting Design Guide
Doc.4775A 12
modular relays for an extra level of flexibility switching 120,
277, and 347 volt loads.
In addition to switching, some Green Light Power Switching
panels also allow the option to add dimming control for 0-10V
dimmable fluorescent ballasts
.
The IPAC-GL1 Control Processor—Crestron has been
manufacturing and innovating microprocessor-based control
systems for lighting and automation longer than anybody,
and all of that know-how has gone directly into the IPAC-GL1.
Right from its front panel, an entire system of lighting loads,
keypads, touchpanels, sensors, and scheduled events
can be programmed without ever having to connect a
computer.
Featuring the same 2-Series control engine as other Crestron
processors, the IPAC-GL1 allows advanced programming to
support all kinds of control options and interfaces, custom
functionality and extensive integration with third-party
systems. Crestron processors also deliver the most
comprehensive capabilities available for remote control
and management over an IP network.
Local Controls—Crestron Green Light simplifies installation by
providing local controls right on the front of each switching
module. Even before the lighting processor gets installed,
these simple controls can be used to switch each load on
and off for testing and operation during construction.
Emergency Override—Remote emergency override capability
allows a power loss sensor (GLS-PLS-120/277) or any
external contact closure to override the lighting system
program and set each circuit to its override preset state. In
a power failure situation using a backup power source, this
allows designated emergency lighting circuits to be turned on
immediately. Override settings can be made easily using the
local controls on the front of each switching module.
Cresnet
®
—Each Green Light Power Switching panel
communicates with the IPAC-GL1, or other Crestron 2-Series
processor, via the Cresnet control network. This simple 4-
wire bus affords proven reliable digital control and flexible
system configuration, carrying data communications and 24
volt DC power to support a complete system of lighting
panels, keypads, touchpanels, sensors, and numerous other
Cresnet devices while connected to an IPAC-GL1 Integrated
Professional Automation Computer.
