Echoflex Installation Guide
Elaho Vacancy Sensor
Wire Specification
Sensors connect to the EchoConnect
®
communication bus. 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 1,640 feet (500 m).
Note:
All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation practices.
Leave approximately 8" (20 cm) of wiring in the back box for connection
and to allow slack for future service needs.
Note:
Echoflex requires that all Elaho stations and devices be grounded
for ESD protection. Pull an additional 14 AWG (2.5 mm
2
) 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 (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.
Installation Environment
Vacancy Sensors are intended for installation to a finished ceiling surface,
ceiling tile mounted, attached to a round fixture junction box or single-gang
RACO switch box.
The sensor operates in ambient temperatures of 0° C to 40° C, with a
maximum of 90% non-condensing humidity.
Echoflex recommends paying special attention to the installation
environment:
•
The sensor must have an unobstructed view of the room. Do not
mount behind or near tall cabinets, shelves, hanging light fixtures, etc.
•
Do not install the sensor within eight feet from an HVAC airflow
duct/vent.
