Low voltage inputs
Blue - (Control input) for
use with an occupancy
sensor, photo control or
other signalling device
providing a maintained
(12 to 24 VDC) voltage
return signaling the
power pack. If the power
pack is in automatic
mode, the power pack
relay will close and turn
on the load. If the power
pack is in manual on
mode, the occupant
must first press the
momentary switch before
the relay will close and
the load will turn on.
When voltage is removed
from the blue input wire
the relay will open and the load will be turned off.
If the momentary switch is
pressed while no voltage
is on the blue wire the load
will turn on for 30 seconds
and then back off.
Orange (Override On)
- intended for use with
maintained (12 to 24VDC)
voltage return from a
time clock, building
management system or
override switch. When
voltage is applied to this
input, the relay will close
and turn the load on
regardless of the position
of the manual/automatic
mode switch on the power
pack. If the momentary
switch is pressed while
voltage is on the orange

wire, the relay will open
and the load will turn off.
When voltage is removed
from the orange (override
on) input, the load will turn
off if there is no signal on
the blue (control) sensor
input.
Brown (force off) - intended
for use with a building
management system,
photo controller, demand
load control or override
off switch providing a
maintained voltage input
of (12 to 24VDC). When
voltage is applied to the
brown (force off) input,
the power pack relay will
open turning the load off
irregardless of occupancy
(blue wire) or force on
(orange wire) inputs. If
the momentary switch
is pressed while there is
voltage to the brown (force
off) input, the load will turn
on for 30 seconds and
then back off. The force
off input overrides all other
inputs to the power pack.
