Field-installed lens masks are provided to allow customized occupancy detection fields for each sensor lens type.

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 Switch Settings on page 8.

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:

• 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 11.

Wire Specification

The 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.

Supplies
The following supplies are provided with the sensor:

• EchoConnect and ESD ground wire pigtails
• Soft ceiling tile adapter
• Mounting screws, 8-32×1 3/4 in

Settings

The Elaho Responsive 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.
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 Responsive 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.

1. Set the Space rotary switch to the desired number (1 through 16) for the space you want the sensor to control.
2. 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 Switch Settings
DIP switches on the sensor electronics provide for additional configuration options including Use Custom Config, Vacancy Timeout, Enable/Disable PIR detection LED, and the ability to restore the sensor to its factory defaults.

• 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), local DIP switch settings for Vacancy Timeout and Enable PIR LED are used.
See Configuration on page 9.
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 (See Vacancy Timeout on page 10.)
5| PIR Detection LED
• When set to On (default), the occupancy detection LED illuminates the lens when movement is detected.
• When set to Off, the occupancy detection LED is disabled unless the unit is in Walk Test mode.
6| Unused (leave Off)
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 LED illuminates for one minute for calibration and warm-up.
The PIR 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, 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.

Operation

• When the space is vacant, 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 Switch Settings on page 8). 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.

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.

2. 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.

3. Adjust the lens masking, if installed, blocking certain areas of the installed space from sensor detection. See Lens Masking below.

4. 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.
