Dual Tech Wall-mount Vacancy Sensor
Wire Specification
The Dual Tech Wall-mount Vacancy 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 etcconnect.com/Support/Cable-Cross-Database for equal
alternatives). The total combined length of an EchoConnect wire run using
Belden 8471 may not exceed 500m (1,640ft), with a maximum distance of
400 m (1,312 ft) between any two devices.
Note:
All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation
practices. Leave approximately 25.4cm (10in) of wiring in the back
box for connection and to allow slack for future service needs.
Note:
ETC requires that all stations and devices be grounded for
ESDprotection. Pull an additional 2.5 mm2(14AWG) wire for
grounding when control wires are not installed in grounded metal
conduit.
Note:
When using Category 5 (or equivalent) cable on the
EchoConnect communication bus, please note the following:
Cat5 wiring must be terminated using EchoConnect Cat5
Termination Kit and must be installed using a bus topology.
Refer to the installation guide that is provided with the Cat5
Termination Kit (7186A1207) 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.
