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 0-40°C
(32-104°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 vacancy detection results. See DIP Switches on
page 7.

Wire Specification
The Dual Tech Ceiling-mount Vacancy 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 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.

Dual Tech Ceiling-mount Vacancy Sensor
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. 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
When the sensor is in Basic configuration mode (DIP switch 2 set to Off), the
sensor will activate a Space Off command when vacancy is detected.
Custom
When functionality other than Space Off is required, place the sensor in
Custom configuration mode (DIP switch 2 set to On). Customization of the
sensor and all actions are configured using the ElahoAccess App.
For more detailed information about custom configuration options available
using ElahoAccess, see the ElahoAccess App integrated help system.
Operation
Dual Technology
When both PIR and acoustic detection are used, the following logic is used:
•
When the space is vacant, only 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 the vacancy timeout in the space has only been reset 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, only manual control can switch the state to
occupied.
•
When the space is occupied, PIR detection and manual control can
reset the vacancy timeout.

Dual Tech Ceiling-mount Vacancy Sensor
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 ten
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 will flash, indicating Walk Test is enabled and the
vacancy timer will be shortened to ten 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 will illuminate 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.
