Step 5: Strip each wire 5/16” (8mm) and terminate the EchoConnect (white
and black wires) and the ground wire (green/yellow) to the
EchoConnect terminal block located on the sensor controller. Torque
each termination to 3.1-3.5 in-lb.
a: Terminate the white incoming wire to the data + terminal.
b: Terminate the black incoming wire to the data - terminal.
c: Terminate the green/yellow (ground) wire to the ground terminal.
Step 6: Attach the sensor to the mounting plate by aligning the tabs on the
sensor with the slots on the mounting plate, then twist clockwise until
the two are secured into place.
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 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.
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 wire, and for the ESD ground wires.
Poke the adapter through the ceiling tile, then bend
it over for a secure fit.
