Combination Normal/Emergency Softswitch® Panel –
Feed-Through Only
Standard-size Softswitch feed-through panels are available with internal separation allowing normal and
emergency circuits to be wired into the same enclosure. Normal circuits are wired into the top section of the
enclosure. Emergency circuits are wired into the bottom section of the enclosure. Each section is controlled by
its own Softswitch controller, and the sections are considered as separate panels during system programming.

Dual-Voltage Control Feed Wiring
Combination Normal/Emergency Softswitch Panels are dual-voltage type and may be fed with either
120 V
or 277 V
.
Wire to either the 120 V
or the 277 V
control feed terminals, not both. The terminals for the unused

PELV (Class 2: USA) Wiring Overview for Combination
Normal/Emergency Softswitch® Panel
System communications use low-voltage PELV (Class 2: USA) wiring.
Wiring must be daisy-chained.
Wiring must run separately from line (mains) voltage.
GRAFIK Eye® 4000 System
PELV (Class 2: USA) wiring link requires:
Two 12 AWG (2.5 mm2) conductors for control power.
One twisted, shielded pair of 18 AWG (1.0 mm2) for data link.
One 18 AWG (1.0 mm2) conductor for Emergency (Essential) sense line, from panel to panel.
Total length of control link may be no more than 2,000 ft. (610 m).
Approved low-voltage cable is available from Lutron,1 Belden, and Liberty. These are approved with 22
AWG data link wires.

• Emergency power: The additional 18 AWG (1.0 mm2) wire is
a “sense” line from terminal 5 of another panel. This sense
line allows an Emergency (Essential) lighting panel to “sense”
when Normal (Non-Essential) power is lost. If more than one
Emergency lighting panel needs to sense from a specific
normal panel, a dedicated wire between each pair of Normal
(Non-Essential) and Emergency (Essential) panels may be
required.
• Shield/Drain: Connect shielding as shown. Do not connect to
Ground (Earth) or circuit selector. Connect the bare drain
wires and cut off the outside shield.
