Soft Ceiling Tile Installation
Step 1: Pull the Belden 8471 (or equivalent) and 14 AWG (2.5mm
2
) ground
wire to the installation location.
Step 2: If you are installing the sensor in series (continuing the data run) to
other sensors, sensor controllers, or stations, use the provided
EchoConnect pigtail and ESD ground pigtail to make the terminations.
If you are not continuing the data run, the pigtails are not required,
proceed to Step 3.
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 the wire nut
c: Repeat the above steps for the data + (typically white)
EchoConnect wires, and for the ESD ground wires.
Step 3: If you are installing the primary and/or optional (second) Light
Sensor Head remotely from the controller, reference Installing the
Light Sensor Heads Remotely (optional) on page 7 , then return to
these instructions. If you are not remoting a Light Sensor Head,
proceed to Step 4.
Step 4: Create a hole for wire pass-through in the ceiling tile by poking through
the center hole or oblong hole of the mounting plate, then pull the wires
through.
Poke the adapter through the ceiling tile, then bend
it over for a secure fit.
