Echoflex Installation Guide
Dual Tech Occupancy Sensor
Wire Specification
The Dual Tech 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. Echoflex
recommends using Belden 8471 Class 2 wire (or approved equal – see the
Echoflex cable cross database
echoflexsolutions.com/files/Elaho_Data_
for equal alternatives). The total combined length of
an 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
devices.
Note:
All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation
practices. Leave approximately 25.4 cm (10 in) of wiring in the
back box for connection and to allow slack for future service
needs.
Note:
Echoflex requires that all stations and devices be grounded
for ESD protection. Pull an additional 2.5 mm
2
(14 AWG) 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 Kits and must be installed using a bus topology.
Refer to the instructions 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.
Supplies
The following supplies are provided with the sensor:
• Soft ceiling tile adapters
• 2 each mounting screws, 6-32x3/4 in and 6-32x1 3/4 in
