ETC Installation GuideUnison Echo® Occupancy Sensor
OverviewThe Echo Occupancy/Vacancy Sensor is a ceiling mounted sensor that utilizes
passive infrared (PIR) technology, providing reliable vacancy and occupancy
detection for lighting control. The sensor provides automatic configuration of
vacancy (auto-off) or occupancy (auto-on/off) functionality based on other
connected control stations. When manual control stations are present, the
sensor will only perform vacancy actions.
Each sensor is available in white or black finish. Lens masks are provided to
allow customized occupancy detection fields as required by each installation.
Custom ConfigurationThis document guides you through the installation and local configuration of
the Echo Occupancy/Vacancy Sensor. For more detailed information about
custom configuration options available for the Echo Occupancy/Vacancy
Sensor using EchoAccess, reference the EchoAccess Mobile App integrated
help system.
Note: To use the configuration settings applied using EchoAccess, DIP switch 2 must be enabled. Reference DIP Switch Settings on page 7.

ETC Installation GuideOccupancy/Vacancy Sensor
Wire SpecificationSensors 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. ETC recommends using Belden 8471 (or approved equal)
Class II wire. The total combined length of an EchoConnect wire run (using
Belden 8471, or equal) may not exceed 1,640 feet (500m).
Installation EnvironmentOccupancy/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.
ETC 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.
• Install the sensor where it cannot easily sense movement in areas
outside of the intended space, such as hallways, glass partitions, or
adjacent rooms. If the installation location cannot avoid these
Note: All control wiring should be installed and terminated by a qualified installer and should follow standard wiring installation practices.
Leave approximately 10 inches (254mm) of wiring in the back box for connection to allow slack for future service needs.
Note: ETC requires that all sensors be grounded. Pull an additional 14 AWG (1.5mm2) wire for grounding when control wires are not installed in grounded metal conduit.
Note: - When using Category5 (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.

Sensor ConfigurationThe Echo Occupancy/Vacancy Sensor participates in an Echo system using the
configured Space and Address, which are selectable using the rotary switches
on the rear panel of the sensor.
Additional DIP switches and the [Mode] button, also located on the rear
panel, set the sensor functionality and the occupancy detected action.
Set Space and AddressTwo rotary switches on the rear panel of the controller provide for assignment
of the sensor Space and Address. By default, these switches are set to Space 1,
Address 1. Commands are shared by all devices within a given space.
Step 1: Set the Space rotary switch to the desired number (1 thru 16)
for the space you want the sensor to control.
Step 2: Set the Address rotary switch to desired address (1 thru 16) for
the sensor identification in the selected space.
Note: Do not duplicate a device Address within the same Space.

ETC Installation GuideOccupancy/Vacancy Sensor
DIP Switch SettingsDIP switches on the rear panel of the Occupancy/
Vacancy Sensor provide for additional
configuration options including Use Custom
Config, Vacancy Timeout, Enable/Disable PIR
detection LED, and the ability to restore the
sensor to its factory defaults.
DIP Switch 2
DIP switch 2 enables “Custom Config” which instructs the sensor to use
settings that are configured using the EchoAccess Mobile App. This setting is
Off by default.
• When “Custom Config” is set to Off, the default position, local DIP
switch settings for Vacancy Timeout and Enable PIR LED are used.
Sensor actions can be adjusted using the program [Mode] button.
• When “Custom Config” is set to On, all other local DIP switch settings
are ignored. Instead, the settings made by the EchoAccess Mobile App
for Vacancy Timeout, Enable PIR LED, and Occupancy actions are used.
DIP Switch 3&4
DIP switch 3 & 4 set the “Vacancy Timeout” to 5, 15, 30 minutes, or Auto.
See “Vacancy Timeout” on page 9.
• 5 min = Switches 3 and 4 are Off.
• 15 min = Switch 3 is Off and Switch 4 is On (default).
• 30 = Switch 3 is On and Switch 4 is Off.
• Auto = Both switches are On. See “Auto Vacancy Timeout” on page 10.
DIP Switch 5
DIP switch 5 enables/disables the red PIR detection LED. When the switch is
Off, the PIR LED disables unless it is in Walk Test mode. When set to On, the
red PIR LED will illuminate the sensor lens when movement is detected. The
default position is On.
DIP Switch 8
DIP switch 8 provides a “Restore Defaults at Boot” function. The factory
defaults are restored by setting this DIP switch On, and cycling power to the
station. The default position is Off.
Note: DIP switches 1, 6, and 7 are not currently used and are reserved for future development. Leave them at their default Off setting.

Power Up and TestPower Up
All EchoConnect terminations in the system must be made before applying
power to the system and sensor. When the sensor is powered up, the PIR LED
illuminates for one minute for calibration and warm-up, and then returns to
normal operation.
ConfigurationSensor configuration for Basic config mode (DIP switch 2 set to Off) can be
accomplished locally on the sensor using the other available DIP switches,
[MODE] button and LED, and the Auxiliary button. See Preset below, and
Vacancy Timeout on page 9 for local configuration instructions.
PresetThe [MODE] button and LED found on the rear panel of the sensor sets the
sensor into “Program Mode.” Both the [MODE] button and LED, and the
Auxiliary “A” button are used for configuration of the occupancy detected
action.
The “A” button and Mode LED are used to program the preset that is
activated with an occupancy detected state change. The Mode LED blinks to
indicate the current preset number used.
Note: The occupancy detected action only matters when using the sensor without manual wall station controls. When manual wall stations are present in the space, the sensor will only control the vacancy action (manual on).

ETC Installation GuideOccupancy/Vacancy Sensor
Step 1: Press and hold the [MODE] button for 3 seconds to enter
“Program Mode.” Program Mode allows adjustment of the
preset that activates for occupancy detection. By default, this
is Preset 1. The “A” button, located on the front of the sensor,
blinks to indicate the preset number controlled by the
occupancy action.
Step 2: Press and release the “A” button the number of times to set
the new preset. (For example: press and release ten times to
set Preset 10.) The “A” button blinks the number of the preset
used for the occupancy event action.
Step 3: Press and release the [MODE] button to save the current
setting. The Mode/Sensor count LED turns off and the “A”
button again blinks out the saved preset index.
Step 4: Attach the sensor to the mounting plate by aligning the tabs
on the sensor with the slots on the mounting plate, then twist
clockwise until the two are locked into place.
Vacancy TimeoutVacancy 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). 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.

Grace PeriodThe 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 TimeoutThe “Auto” vacancy timeout setting varies vacancy the timeout between
5 and 30 minutes depending on how often it identifies an occupancy trigger
after a vacancy timeout occurs (during the grace period).
Lens MaskingLens masks are provided in the packaging for your convenience, used to block
a section of the lens from detecting occupancy.
PIR DetectionThe PIR detection automatically adjusts its sensitivity to eliminate nuisance
tripping. When the sensor powers on, the red PIR LED illuminates for
approximately 60 seconds to identify “Power Up” state. Sensor configuration
is not allowed. During this time, no events are triggered.
Step 1: As needed, trim the lens
mask to fit the desired
area to be blocked.
Step 2: Gently press down on the
sensor lens, which will
give only slightly, and
insert the lens mask.
Step 3: Rotate the lens mask
around the dome to block
the required area from
occupancy sensing.

TestOccupancy/Vacancy Sensors offer a Walk Test mode which shortens the
vacancy timer to 10 seconds, allowing for simple and quick verification of the
sensors coverage and range in the installed space.
Enable Walk Test ModeStep 1: Prepare the site for configuration.
a: Make certain the sensor and lighting loads are powered
and connected for control by the Echo controller.
b: You will need direct access to the Occupancy/Vacancy
Sensor in order to place it into Walk Test mode.
Step 2: Press the [Walk Test] button on the front of the sensor to
enable the Walk Test feature at the sensor. A green LED will
begin to flash, indicating Walk Test is enabled and the
vacancy/no vacancy occupancy timer will be shortened to 10
seconds.
Step 3: Move throughout the space including corners and areas that
may specifically be obscured from line of sight to the sensor.
Each time the sensor detects movement, the lens will
illuminate red.
Step 4: Adjust the lens masking, if installed, blocking certain areas of
the installed space from sensor detection. See “Lens Masking”
on page 10.
Step 5: Walk Test mode will automatically exit after five minutes from
the time it was enabled. To manually exit the Walk Test mode,
press either of the buttons on the sensor.
