Control Wire Specification
Wall-mount Occupancy Sensors connect to the LinkConnect station
communication bus. LinkConnect is a bidirectional protocol that uses one
pair of wires (data+ and data-) for both data and power. ETC recommends
using Belden 8471 (or approved equal) Class 2 wire. The total combined
length of a LinkConnect wire run (using Belden 8471, or equal) may not
exceed 1,640 feet (500 m) with a maximum distance of 1,312 feet (400 m)
between any two devices.
Parts and Supplies
The following parts and supplies are included with the sensor:
• mounting bracket with pre-routed LinkConnect pigtail wires
• mounting screws
• WAGO (wire termination connectors)
Installation
Installation should follow all local codes and standard electrical practices.
Note: All control wiring should be installed and terminated by
a qualified installer and should follow standard wiring
installation practices. Leave approximately 10 inches
(254 mm) of wiring in the switch box for connection and
to allow slack for future service needs.
Note: ETC requires that all stations be grounded. Pull an
additional 14 AWG (2.5 mm
2
) wire for grounding when
control wires are not installed in grounded metal
conduit.
Note: NEC Class 2 product to be wired in accordance to NEC
Article 725 and local jurisdiction requirements.
