Light Sensor
Wire Specification
Controller
The Light Sensor controller utilizes EchoConnect for power and for data
communications with an Elaho control system.
EchoConnect is a bidirectional protocol that uses one pair of wires (data +
and data -) for both data and power. Echoflex recommends using Belden
8471 (or approved equal) Class 2 wire.
The total combined length of an EchoConnect wire run (using Belden 8471,
or equal) may not exceed 500 m (1,640 ft).
Note:
qualified installer and should follow standard wiring installation
practices.
Leave approximately 20 cm (8 in) of wiring in the back box for
connection and to allow slack for future service needs.
Note:
grounded for ESD protection. Pull an additional 2.5 mm
wire for grounding when control wires are not installed in grounded
metal conduit.
Note:

•
Termination Kit and must be installed using a bus topology.
Refer to the installation guide that is provided with the Cat5
Termination Kit (8186A1207) for information to terminate
Cat5 wiring.
Not all topologies are supported using Cat5; careful planning
•
is required to ensure the proper termination kits are available
and the wire is pulled appropriately.
Light Sensor Head
The Light Sensor controller provides termination for up to two remote Light
Sensor heads. Each Light Sensor head must be separately wired to the
controller using no more than 304 m (1,000 ft) of 1.5 mm
total per controller. These wire runs must remain separate from EchoConnect
wiring. Echoflex recommends using Belden 8471 (or equivalent) wire.
