Echoflex Installation Guide
Dual Tech Occupancy Sensor
Prepare for Installation
Ceiling-mount sensors are intended for installation to a finished ceiling
surface, soft ceiling tile mounted, or attached to a round or octagonal
fixture junction box.
Compliance
• cULus Listed
• CE compliant
For use with Echoflex Elaho Control Systems, powered by an Elaho station
power supply.
Environment
Ambient
For indoor, commercial controls use only. Operating temperature
0°C–40°C (32°F–104°F), humidity maximum 90%(non-condensing).
Location
Echoflex 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. If the installation location cannot avoid these
conditions, portions of the lens can be masked to block the sensor
view of these undesired areas. See Lens Masking on page10 .
Note: In areas of increased noise activity, enabling PIR only mode
may allow for better detection results. See DIP Switches on page
7.

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_
Cable_Wire_Specs 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 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 (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

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.
Configuration
Basic
MODE button
and LED
AUXILIARY
button
and LED
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.
Custom
A sensor that is set for Custom configuration mode (DIPswitch 2 set to
On, the default setting) can be customized using the ElahoAccess App.
For more detailed information about custom configuration options
available, see the ElahoAccess App integrated help system.
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.
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.
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.
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]
1. Prepare the site for configuration.
a. Make certain the sensor and lighting loads are powered and
connected for control by the Elaho 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 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. Adjust the lens masking, if installed, blocking certain areas of the
installed space from sensor detection. See Lens Masking below .
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.
Lens Masking
Lens masks are provided in the packaging for your convenience. Use this
to block a section of the lens from detecting occupancy. To attach, cut to
the desired size, remove the backing and stick it on the sensor lens,
covering the desired sections.
