Dual Tech Switch-mount Occupancy Sensor
Overview
The Elaho Dual Tech Switch-mount Occupancy Sensor is a switch station with a
built-in sensor that uses passive infrared (PIR) and acoustic detection to
provide reliable occupancy and vacancy sensing for lighting control.
The Dual Tech Switch-mount Occupancy Sensor is available in one- and two- button models, and is available with white, black, cream, or gray wall plate.
Each button is backlit by both blue and amber LEDs to show changes in status.
The sensor provides a 180 degree field of view with up to 13.7 m (45 ft)
radius for large motion detection. This document guides you through the
installation and local configuration and setup of the Dual Tech Switch-mount
Occupancy Sensor.
Custom Configuration
For more information about the custom configuration options available using
ElahoAccess, reference the ElahoAccess Mobile App integrated help system.
Note: Settings made using ElahoAccess are applied only when the function
selection switch is set to Custom (middle position). Reference Function Switch
on page 11.
Prepare for Installation
Elaho Dual Tech 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 Echoflex).
Environment Ambient
For indoor, commercial controls use only. Indoor installation only. The sensor
operates in ambient temperatures of 0°C to 40° C (32°F to 104°F), with a
maximum of 90% non-condensing humidity.
Installation
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 2.4 m (8 ft) of 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 vacancy detection results. Reference DIP Switch Settings on page 6.
Wire Specification
The Dual Tech Switch-mount 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 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.
Parts and Supplies
The following parts and supplies are included with the sensor:
- mounting screws
- EchoConnect termination kit
- WAGO 221 Series LEVER-NUTS® (wire termination connectors)
- decorator style wall plate
Installation
Installation should follow all local codes and standard electrical practices.
Note: NEC Class 2 product to be wired in accordance to NEC Article 725
and local jurisdiction requirements.
The back box should be installed plumb and square for best results. Ensure
that the box is clean and free of obstructions and that all wiring is
installed correctly.
Dual Tech Switch-mount Occupancy Sensors ship with a termination kit for use
with Belden 8471 (or equivalent wire), and include power and ground wire
pigtails, receptacle spacers, and all required wire termination connectors for
installation.
Connect Wiring
- Pull all required wiring (data+, data-) into the back box. As needed, pull an additional ESD ground wire (required only when the station is not installed in grounded metal conduit).
- Connect the station ESD ground wire pigtail.
- Strip 11 mm (7/16 in) of insulation from the ends of the station ground wire pigtail, provided in the termination kit, and the incoming ground wire.
- Use one WAGO connector, provided in the termination kit, to connect the station ESD ground pigtail and the incoming ground. For stations using grounded metal conduit, connect the ground pigtail to the metal back box ground location.
- Install the ESD ground wire pigtail FASTON connector to the mating receptacle on the station electronics.
- Terminate Echo Connect wires. Echo Connect is topology free; you may install the wires in any combination of bus, star, loop, or home-run.
- Strip 11 mm (7/16 in) from the ends of each power pigtail wire provided in the termination kit and the installed control wires.
- Use the provided WAGO connectors to connect the power pigtail wires and the installed Belden 8471 control wires. One WAGO should be used for the white wire pair (data +) and one for the black wire pair (data -). Open the terminal levers on the WAGO connector and insert the installed Belden 8471 wire and the lead from the power pigtail into the terminals, and then close the levers.
- Install the two-pin connector from the power pigtail to the mating receptacle on the station electronics.
Rotary and DIP Switches
Rotary and DIP switch settings are accessible on the rear of the station.
Set Space and Address
The two rotary switches provide for assignment of the sensor space and address. Each sensor must be set to a unique station address for the assigned space. By default, these switches are set to Address 1, Space 1. Commands are shared by all devices within an assigned 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.
CAUTION: Each device on the bus must have its address set to a unique number (1 through 16) for the space it controls. If two or more devices use the same address for the same space, the system will not function properly.
DIP Switch Settings
DIP switches provide for designation of “Off” functionality, the ability to disable amber button LEDs, and the ability to restore the sensor to its factory defaults.

number 8 applies. All other DIP switch settings are ignored.
Reference Station Configuration on page 11 for local configuration settings on
your Dual Tech Switch-mount Occupancy Sensor. Reference the ElahoAccess Mobile
App integrated help system for details about custom configuration using the
ElahoAccess Interface.
Install Button Legends
Elaho Dual Tech Switch-mount Occupancy Sensors ship with standard button
legends installed beneath a clear lens.
Note: Customize and print your own button legends on standard
transparency. Download the button legend template provided on the Echoflex
website echoflexsolutions.com.
Each button can have a legend, installed beneath the button lens. To remove,
install, or replace a button legend you must first remove the bezel and button
lens from the station electronics.
-
Remove the bezel from the station electronics.
- Each corner of the bezel is provided with a notch to assist with bezel removal. Use a finger nail to lift a corner free, then gently remove the bezel from the station.
-
Remove the button lens.
- Using the pad of your thumb, press on the lens and slide the lens left, toward the hinge points.
-
Once the lens is removed, remove the existing legend and insert a custom legend.
-
Replace the lens onto the button by aligning the rim grooves of the lens to the button, then sliding the lens in place starting at the hinge. Slide the lens n Entry until it covers the entire button and clicks into place.
-
Replace the bezel to the station electronics when all legends and lenses are in place.
Install the Station
Receptacle spacers are provided for use in flush mount applications to help align the station and cover flush against the wall.
- Insert the station electronics and wiring into the back box. To install multiple stations (multi-gang), insert the station electronics into the box from the right to the left side for the best alignment and fit. The alignment bracket will slightly overlap the station to the right when properly installed.
- Use spacers as needed to provide a flush mounted station.
- Fold the spacer in a zig-zag fashion and press the stack together to achieve the thickness needed to fill the gap between the station, wall surface, and the back box.
- Cut off and discard the excess.
- Place the stack between the station electronics and the flush mounted back box.
- Secure each station electronics in place using the two screws provided. If using spacers, insert the screws through the spacers as well.
CAUTION: To improve successful station and wall plate installation, do not over tighten the screws. If screws are over tightened, button activation can be negatively impacted.
Install the Wall Plate
The wall plate is secured to the station with built-in magnets.
- Align the top of the wall plate to the station and angle the bottom approximately 20 degrees.
- Hook the top of the wall plate to the tabs located on the station electronics assembly. To ensure the wall plate is hooked properly on the top hook, wiggle it slightly side to side.
- Swing the bottom of the wall plate down until the magnets engage.
- If the wall plate does not fully attach automatically, wiggle the bottom of the plate until all of the magnets are seated properly to the station and the plate is secure.
Note: When installing a multi-gang wall plate and the stations are misaligned in the mounting box, the wall plate will not attach properly. Loosen the screws that secure the station to the box, adjust each station to improve the alignment, secure the screws, then retry wall plate installation.
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.
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.
Dual Technology Detection
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.
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.
- Make certain the sensor and lighting loads are powered and connected for control by the Elaho control system.
- You will need direct access to the sensor in order to place it into Walk Test mode.
- Remove the sensor wall plate to gain access to the Walk Test button.
- Press the Walk Test button on the top right 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.
- 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.
Station Configuration
The Dual Tech Switch-mount Occupancy Sensor has on-board switch and button
settings that are available from the front of the station when it is installed
and the wall plate is removed.
Program Mode Press and hold the Walk Test button three seconds to enter
Program Mode
Function Switch
Preset Custom
Zone
Program Mode
Program Mode allows adjustment of the consecutive range of presets or zones
assigned to the station. Placing the station in Program Mode allows you to set
a new starting preset or zone number for the station.
The programmed preset or zone that is associated to the first button control
is also the event/action that will occur with occupancy and vacancy detection.
Reference Program Preset Start (Basic Mode, Preset, or Zone) on page 13.
Function Switch
The Function switch determines how the controls of the sensor function. It has
behavior settings of Preset, Custom, and Zone.
Function Switch: Preset
Setting the Function switch to Preset allows you to perform preset related
actions dependent on the switch-mount sensor type. Reference Station
Functionality on page 15 for complete details of the button actions when the
switch-mount sensor is placed in Preset mode.
Preset Toggle Functionality
Preset toggle control functionality allows you to toggle the preset on and off
by pushing the assigned preset button.
- A single button push activates/deactivates the preset that is assigned to that button using a two second fade time.
- A double button push activates/deactivates the preset that is assigned to that button using a 1/2 second fade time.
When a preset is active, the button LED lights blue to indicate its active state. If preset levels are altered while the preset is still active, the related button LED will return to its default state, either off or amber. Reference DIP Switch Settings on page 6.
Use Off Functionality (Two-button Switch-mount Sensor Only)
“Use Off” functionality enables the last button on the station with a
dedicated space off action.
- A single push of the “Off” button sets the level of all zones to zero using a two second fade time.
- A double push of the “Off” button sets the level of all zones to zero using a 1/2 second fade time.
“Use Off” functionality is enabled when DIP switch 1 is set to On. Reference
DIP Switch Settings on page 6.
Note: The one-button switch-mount sensor does not recognize “Use Off”
functionality.
Function Switch: Custom
Setting the Function switch to Custom (the middle switch setting) allows for
varied features either with or without ElahoAccess, although the presence of
ElahoAccess in the control system allows for an expanded feature set.
With ElahoAccess
ElahoAccess provides complete customization of the switch-mount sensor when it
is in Custom control mode. For more information on the configurable device
parameters and actions available, reference the ElahoAccess Mobile App
integrated help system.
Note: Changes made in ElahoAccess impact the Custom Function switch
setting of the sensor only. Preset and Zone Function switch settings remain
unaffected by the changes made while using ElahoAccess configuration tools.
Without ElahoAccess
Reference Station Functionality on page 15 for default functions when the
switch-mount sensor Function switch is set to Custom control mode and you do
not have ElahoAccess to customize the features.
Function Switch: Zone
Setting the Function switch to Zone (the lowest switch setting) allows you to
manually control the level of a zone using on/off and space raise or space
lower (two-button switch-mount sensor only) functionality.
Zone Toggle Functionality
While the Function switch is set to Zone, the station allows you to toggle the
zone on and off. The controlled zone level raises to full or toggles off using
a 1/2 or two second fade time, depending on the station type. Reference
Station Functionality on page 15.
Zone Raise/Lower Functionality
Zone raise/lower functionality varies depending on the switch-mount sensor
type. The one-button switch-mount sensor provides zone raise functionality
only. The two-button switch-mount sensor provides both zone raise and zone
lower functionality. Reference Station Functionality on page 15.
Program Preset Start (Basic Mode, Preset, or Zone)
Note: Program Mode only affects station behaviors when the Function
switch is set to Preset or Zone and does not affect any behaviors in Custom
mode.
Note: The preset that is configured to the first button control on the
sensor is also the event that will occur with occupancy detection. Space Off
will occur with vacancy detection.
- Set the station Function switch to Preset (the highest switch position).
- Press and hold the Walk Test/Program Mode button for three seconds to enter Program Mode. The “Mode” LED illuminates (steady amber) and the first button control LED for the station flashes the current (first) preset controlled. (For example, if the first preset controlled is Preset 3, the button LED will flash three times.)
- Push button 1 to increase the starting preset number by one; any new count always begins at 1. The station updates the LED indication, flashing the LED to reflect the new preset number. (For example, pushing the button control eight times sets the first preset for the station to Preset 8.) All station preset controls are consecutively assigned beginning with the specified count.
- When the desired preset number is set, press and release the Walk Test/Program Mode button to save the new setting. The “Mode” LED turns off and the button LED blinks the new setting before returning to normal operation.
Note: To change the assignment to a lower number than what is currently set, exit Program Mode then reenter Program Mode; the preset count will restart at 1.
Program Zone Start
Note: The zone that is configured to the button controls is also the zone that will be activated at full with occupancy detection and deactivated with vacancy detection.
- Set the station Function switch to Zone (the lowest switch position).
- Press and hold the Walk Test/Program Mode button for three seconds to enter Program Mode. The “Mode” LED illuminates (steady amber) and the first button control LED for the station flashes the current (first) zone controlled. (For example, if the first zone controlled is Zone 5, the button LED flashes five times.)
- Push button 1 to increase the starting zone number by one; any new count always begins at 1. The station updates the LED indication, flashing the LED to reflect the new zone number. (For example, pushing the button control three times sets the first zone for the station to Zone 3.) All station zone controls are consecutively assigned beginning with the specified count.
- When the desired zone number is set, press and release the Walk Test/Program Mode button to save the new setting. The “Mode” LED turns off and the button LED blinks the new setting before returning to normal operation.
Note: To change the assignment to a lower number than what is currently set, exit Program Mode then reenter Program Mode; the zone count will restart at 1.
