Elaho Dual Tech Wall-mount Vacancy Sensor
Overview
The Elaho Dual Tech Wall-mount Vacancy Sensor uses passive infrared (PIR)
technology and acoustic detection to provide reliable vacancy sensing for
lighting control. The sensor relies on local station control for manual on and
provides auto off functionality upon detection of vacancy. The wall-mount unit
offers up to 140 degree field of detection with optimized lens options to
accommodate wide or narrow angle spaces.

- 18.3 m (60 ft) at mounting height of 2.1–3 m (7–10 ft)
- 140 degree field of detection
Wall-mount – Narrow Angle Lens – coverage
- 4.9×22.9 m (16×75 ft) at mounting height of 1.8–2.1 m (6–7 ft)
- 40 degree field of detection
See Sensor Coverage on page 11.
Custom Configuration
This document guides you through the installation and local DIP switch setup
of the sensor. For more detailed information about custom configuration
options available using ElahoAccess, see the ElahoAccess App integrated help
system.
Note: To use the configuration settings applied using ElahoAccess, DIP
switch 2 must be enabled. See DIP Switches on page 7.
Prepare for Installation
Elaho Dual Tech Wall-mount Vacancy 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 Echoflex).
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.
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 Wall-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 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.

Settings
The Elaho Dual Tech Wall-mount Vacancy Sensor participates in an Elaho 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, also located on the sensor electronics, set the sensor
functionality. Note: When the sensor is placed into Custom configuration
mode, DIP switch 2 set to On, all other DIP switch settings are ignored.
Note: The [MODE] and Auxiliary [A] buttons, and their related LEDs, are
not used and have no functionality on the Dual Tech Wall-mount Vacancy Sensor.
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.
- Set the Space rotary switch to the desired number (1 through 16) for the space you want the sensor to control.
- 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.
DIP Switches
DIP switches on the sensor electronics provide for additional configuration
options including Use Custom Config, Vacancy Timeout, Enable/Disable detection
LEDs, PIR Only Mode, and the ability to restore the sensor to its factory
defaults.
Switch # | Use |
---|---|
1 | Unused (leave Off) |
2 | Enable/Disable Custom Config Mode |
• When “Custom Config” is set to On (the default setting), all other local DIP
switch settings are ignored. Instead, the settings made by the ElahoAccess App
are used.
• When “Custom Config” is set to Off, also known as Basic configuration mode,
the local DIP switch settings for Vacancy Timeout, Enable PIR LED, and dual
technology features are used. See Configuration on page 8.
3 and 4| Vacancy Timeout
• 5 min = Switches 3 and 4 are Off
• 15 min = Switch 3 is Off and Switch 4 is On (default)
• 30 min = Switch 3 is On and Switch 4 is Off
• Auto = Both switches are On
5| Detection LEDs
• When set to On (the default setting), the occupancy detection LEDs
illuminate when movement is detected.
• When set to Off, the occupancy detection LEDs are disabled unless the unit
is in Walk Test mode.
6| PIR Only Mode
• When set to On, acoustic detection technology is disabled for the sensor.
• When set to Off (the default setting), both PIR and acoustic detection
technologies are used by the sensor.
7| Unused (leave Off)
8| Restore to Defaults at boot
• When set to On and power is cycled to the sensor, the unit restores to its
factory default settings.
• Off is the default setting.
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, 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.
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, the default setting).
Customization of the sensor and all actions are configured using the
ElahoAccess App. For more detailed information about custom configuration
options available, see the ElahoAccess App integrated help system.
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.
-
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. -
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.
-
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.
-
As needed, adjust the angle of the sensor head to obtain optimal detection in the space.
-
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.
