Prepare for Installation
Echo Switch-mount Occupancy Sensors ship with electronics, a decorator
style wall plate, and a termination kit. The sensor may be installed into an
industry standard back box (provided by others) or surface mounted back box
(sold separately and available from ETC).
Compliance
• UL/cUL listed, complies with UL508A, UL916, and CSA C22.2
• CE compliant
For use with ETC dimming and relay products.
Environment
Ambient
For indoor, commercial controls use only. Indoor installation only. The sensor
operates in ambient temperatures of -10°C to 40°C, with a maximum of
90% non-condensing humidity.
Installation
ETC recommends paying special attention to the installation environment:
• When operating in PIR only modes, 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.
Control Wire Specification
Switch-mount Occupancy 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. ETC 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 1,641 feet (500 m).
Note:
In areas of increased noise activity, enabling PIR only
mode may allow for better vacancy detection results.

Power Up and Test
Power 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 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 sensitivity threshold to eliminate nuisance tripping. During this time,
sensor configuration is not allowed and no events are triggered.
Dual Technology Detection
When both PIR and acoustic detection are used, the following logic is
followed:
• 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.

ETC Installation Guide
Switch-mount Occupancy Sensor
Echo Dual Tech Switch-mount Occupancy Sensor Page 11 of 20 ETC
Walk Test
The sensor offers a Walk Test mode, which shortens the vacancy timer to ten
seconds and allows for simple and quick verification of the sensor’s coverage
and range in the installed space.
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: Remove the sensor wall plate to gain access to the [Walk Test] button.
3: Press the [Walk Test] button on the top right 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 timer will be
shortened to ten seconds.
4: 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. If acoustic
detection is enabled, any sound detected will illuminate the lens
green.
5: Walk Test mode will automatically exit and return to normal operation
after five minutes. You can also manually terminate by pressing the
[Walk Test] button again.
