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 etcconnect.com/Support/Cable-
Cross-Database 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: ETC requires that all stations and devices be grounded for
ESDprotection. Pull an additional 2.5 mm2(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 (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.
Supplies
The following supplies are provided with the sensor:
• mounting bracket with pre-routed EchoConnect and ground wires
• 2 each mounting screws, 6-32x3/4in and 6-32x1 3/4in

Settings
MODE AUX
The Echo Dual Tech Wall-mount Occupancy
Sensor participates in an Echo control system
using the configured Space and Address,
which are selectable using the rotary
switches on the sensor electronics located
behind the removable cover.
DIP switches and the [MODE] button, also
located on the sensor electronics, set the
sensor functionality and the occupancy
detection action when set to Basic
configuration mode. See Configuration on page8 .
Note: When the sensor is placed into Custom configuration
mode, DIP switch 2 set to On, all other DIP switch and Mode
button settings are ignored.
Set Space and Address
Two rotary switches on the sensor electronics provide for Space and
Address assignment for the sensor. By default, these switches are set to
Space1, Address1. Commands are shared by all devices within a given
space.
1. Set the Space rotary switch to the desired number (1 through 16)
for the space you want the sensor to control.
2. Set the Address rotary switch to desired address (1 through 16) for
the sensor identification in the selected space.
Note: Do not duplicate a device Address within the same Space.

Power Up
All EchoConnect terminations in the system must be made before
applying power to the system and sensor. When the sensor is powered,
the PIR and acoustic detection LEDs illuminate for one minute for
calibration and warm-up, and then return to normal operation according
to the configuration.
Both the PIR and acoustic detection features of the sensor will
automatically adjust the sensitivity threshold to eliminate nuisance
tripping. During this time, configuration is not allowed and no events are
triggered.
Operation
Dual Technology
When both PIR and acoustic detection are used, the following logic is
used:
• When the space is vacant, PIR detection and manual control can
switch the state to occupied.
• When the space is occupied, PIR, acoustic detection, and manual
control can reset the vacancy timeout.
• When occupancy in the space has only been triggered by acoustic
detection for 60 minutes, acoustic detection is disabled until the
next PIR detection event.
PIR (only) Detection
When acoustic detection is disabled (DIP switch 6 set to On), the
following logic is used:
• When the space is vacant, PIR detection and manual control can
switch the state to occupied.
• When the space is occupied, PIR detection and manual control can
reset the vacancy timeout.
Configuration
Basic
A sensor that is set for Basic configuration mode (DIPswitch 2 set to Off)
can be further configured locally using the other available DIPswitch
settings, and the [MODE] and Auxiliary [A] buttons and their associated
LEDs. See Program Mode on the facing page .
Custom
A sensor that is set for Custom configuration mode (DIPswitch 2 set to
On, the default setting) can be customized using the EchoAccess App. For
more detailed information about custom configuration options available,
see the EchoAccess App integrated help system.

ETC Installation Guide
Dual Tech Wall-mount Occupancy Sensor
Program Mode
MODE AUX
Program Mode allows for local configuration of a
sensor that is set for Basic configuration mode (DIP
switch 2 set to Off). All basic configuration is set
locally on the sensor using the other available DIP
switches, the [MODE] button and associated amber
Mode LED, and the Auxiliary [A] button and
associated blue Auxiliary LED.
The mode and auxiliary buttons and LEDs are
located on the sensor electronics, accessible with
the cover removed. See Preset below and Vacancy Timeout below for
local Echo Program Mode configuration instructions.
Preset
While in Basic configuration mode (DIPswitch 2 set to Off), use the
[MODE] and Auxiliary [A] buttons to program the preset that is activated
with an occupancy detected state change. By default, this is Preset1.
When vacancy is detected, the default action event is Off.
Follow these steps to configure the preset for your sensor:
1. Access the sensor electronics and press and hold the [MODE]
button for three seconds to enter “Program Mode.” The Mode LED
lights in amber to indicate the sensor is in Program Mode and the
Auxiliary LED flashes to indicate the preset number controlled by
the occupancy action. By default, this is Preset 1, therefore the LED
will flash one time, pause two seconds and flash again.
2. Press and release the Auxiliary [A] button the number of times that
corresponds to the preset that you want to use. For example, press
the [A] button eight times to set Preset 8. The LED flashes the
number of the preset used.
3. Press and release the [MODE] button to save the current setting.
Vacancy Timeout
Vacancy timeout is the amount of time the sensor waits to take action
after no movement is detected. By default, vacancy timeout is set to 15
minutes (indicated by DIP switch 3 set to Off and 4 set to On; see DIP
Switches on page 7 ). When the vacancy timeout ends, the grace period
begins.
When the sensor detects vacancy, the vacancy timeout period begins. If
the sensor does not detect occupancy again during the vacancy timeout
period, the lights turn off and a 30 second grace period begins.
Dual Tech Wall-mount Occupancy Sensor Page 9 of 12 ETC

ETC Installation Guide
Dual Tech Wall-mount Occupancy Sensor
Grace Period
The sensor features a 30 second grace period after a vacancy timeout
occurs. During this grace period, if the sensor detects occupancy, it will
turn on or restore the previous lighting condition.
Auto Vacancy Timeout
The “Auto” vacancy timeout setting varies the vacancy timeout between
5 and 30 minutes depending on how often it identifies an occupancy
trigger after a vacancy timeout occurs (during the grace period).
Walk Test
The sensor offers a Walk Test mode, which shortens the vacancy timer to
10seconds and allows for simple and quick verification of the sensor’s
coverage and range in the installed space.
[Walk Test]
button
1. Prepare the site for configuration.
a. Make certain the sensor and lighting loads are powered and
connected for control by the Echo control system.
b. You will need direct access to the sensor in order to place it into
Walk Test mode.
2. Press the [Walk Test] button on the bottom of the sensor to enable
the Walk Test feature. A green LED flashes, indicating Walk Test is
enabled and the vacancy timer is shortened to 10seconds.
3. Move throughout the space, including corners and areas that may
be obscured from line of sight to the sensor. Each time the sensor
detects movement, the lens illuminates red. If acoustic detection is
enabled, any sound detected illuminates the lens green.
4. As needed, adjust the angle of the sensor head to obtain optimal
detection in the space.
5. Walk Test mode automatically exits and the sensor returns to
normal operation after five minutes. You can also manually
terminate by pressing the [Walk Test] button again.
