Dual Tech Wall-mount Occupancy Sensor
Wire Specification
The Dual Tech Wall-mount Occupancy Sensor connects to the
EchoConnect communication bus. EchoConnect is a bi-directional
protocol that uses one pair of wires (data+ and data–) for both data and
power. ETC recommends using Belden 8471 Class 2 wire (or approved
equal – see the ETC cable cross database
Cross-Database
EchoConnect wire run using Belden 8471 may not exceed 500 m
(1,640 ft), with a maximum distance of 400 m (1,312 ft) between any two
