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 ETC Echo Control Systems, powered by an Echo 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

ETC 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.

Dual Tech Vacancy Sensor

Wire Specification

The Dual Tech 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. ETC recommends using Belden

8471 Class 2 wire (or approved equal - see the ETC cable cross database

etcconnect.com/Support/Cable-Cross-Database 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:

ETC 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 (7186A1207) 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.

ETC Installation Guide

Dual Tech 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 EchoAccess App.

For more detailed information about custom configuration options available

using EchoAccess, see the EchoAccess 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 Vacancy Sensor Page 8 of 12 ETC

ETC Installation Guide

Dual Tech 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).

Dual Tech Vacancy Sensor

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 Echo 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.
