INTRODUCTION
The DI inputs of the Blue Box allow a single occupant sensor
to control multiple relays in a variety of different scenarios .
Sensors may be disabled by time of day if the DI6 is used, or
may be included as part of a combined occupant sensor /
daylight harvesting controls strategy .
Sensors from any manufacturer are allowed long as they
have an "-R" (relay option) or dry contact output . Hook
up is similar to a traditional power pack . Occupant sensors
may be powered by the regulated 24 V dc/300 mA supply

PROGRAMMING AN OCCUPANT SENSOR
Gnd
3.3V
Once the occupant sensor has been connected to the
24V
low-voltage dry contact input on the DI card, the input
must be programmed .
All occupant sensors have contacts that send a "maintain"
type closure to the dry contact inputs on the DI card and
INPUT X
therefore must be programmed as such .

THE BLUE BOX LT OCCUPANT SENSORS
TO PROGRAM A DI INPUT
1 . Navigate to the DI card inputs: USER MENU > PRO-
GRAM SWITCH > SWITCH # > BUTTON #
2 . Add/delete LOADs (relays) to the input(s) to which
the occupant sensor(s) are connected . TAB to the
Control Type and set it to "Maintain . "
3 . If more than 8 relays need to be added, create a new
Group you will be asked if you wish to press yes to
accept .
4 . Navigate back to the DI input and SCROLL to the
Control Type and select the Group that contains the
relays .
For more information on Groups and Group types, refer
to the relevant section in the O&M .
Refer to the specific hook-up diagrams on the next
pages. Sensors can use the onboard power supply from
the DI card.
