Refer to the specific hook-up diagrams on the next
pages. Sensors can use the onboard power supply from
the DI card.
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
on the DI card.
PROGRAMMING AN OCCUPANT SENSOR
Once the occupant sensor has been connected to the
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
therefore must be programmed as such.
TO PROGRAM A DI INPUT
Navigate to the DI card inputs: USER MENU > PRO-1.
GRAM SWITCH > SWITCH # > BUTTON #
Add/delete LOADs (relays) to the input(s) to which 2.
the occupant sensor(s) are connected. TAB to the
Control Type and set it to “Maintain.”
If more than 8 relays need to be added, create a new 3.
Group you will be asked if you wish to press yes to
accept.
Navigate back to the DI input and SCROLL to the 4.
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.
