Installation
The Occupancy/Vacancy Sensor is provided with a twist-lock mounting plate
that can be mounted to a junction box, finished ceiling or soft ceiling tile.
Determine the installation method and follow the detailed instructions:
• See “Junction Box Installation” on page 3.
• See “Soft Ceiling Tile Installation” on page 4.
• See “Lens Masking” on page 8.
Junction Box Installation
a: Strip each wire to the appropriate length, depending on the wire nut
or other termination used (wire nuts are not provided).
b: Twist the data - (typically black) EchoConnect wire, the black lead
from the EchoConnect pigtail, and any continuing EchoConnect
(typically black) wire together and secure with a wire nut.
c: Repeat the above steps for the data + (typically white)
EchoConnect wire and the ESD ground wire.
Step 3: Orient the smooth side of the mounting plate to the junction box and
pull the EchoConnect wires (or terminated pigtail) from the junction
box through the provided holes near the center of the mounting plate.
Step 4: Secure the mounting plate to the junction box using the screws
provided (both short and long screws are provided for convenience).

wires here
Step 1: Pull the Belden 8471 (or
equivalent) and 14 AWG
(2.5mm
2
) ground wire to the
junction box.
Step 2: If you are installing the
sensor in series with other
sensors or stations
(continuing the data run), use
the provided EchoConnect
pigtail, ESD ground pigtail
and connectors (not
provided) to make the
terminations. If you are not
continuing the data run,
proceed to Step 3.
