Overview
The Elaho Vacancy Sensor is a ceiling mounted sensor that utilizes passive
infrared (PIR) technology, providing reliable vacancy detection for lighting
control. The sensor relies on local station control for manual on and provides
auto off functionality upon detection of vacancy.
The Vacancy Sensor provides 360 degree coverage of the
installed location and is available in three models:
•
E-VAC-SR- Vacancy Sensor with small room lens
covers 450 sq. ft. at 8 ft./ 800 sq. ft. at 10 ft.
•
E-VAC - Vacancy Sensor with standard room lens
covers 1,800 sq. ft. at 8 ft./ 3,000 sq. ft. at 10 ft.
•
E-VAC-HC - Vacancy Sensor with high ceiling lens
covers 300 sq. ft. at 10 ft./ 7,000 sq. ft. at 40 ft.
Each sensor is available in white or black finish. Lens
masks are provided to allow customized vacancy
detection fields as required by each installation.

Elaho Vacancy Sensor
Wire Specification
Sensors connect to the EchoConnect®communication bus. EchoConnect is a
bidirectional protocol that uses one pair of wires (data + and data -) for both
data and power. Echoflex recommends using Belden 8471 (or approved equal)
Class 2 wire. The total combined length of an EchoConnect wire run (using
Belden 8471, or equal) may not exceed 1,640 feet (500 m).
Note: All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation practices.
Leave approximately 8" (20cm) of wiring in the back box for connection
and to allow slack for future service needs.
Note: Echoflex requires that all Elaho stations and devices be grounded
for ESDprotection. Pull an additional 14AWG (2.5 mm2) 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.
Installation Environment
Vacancy Sensors are intended for installation to a finished ceiling surface,
ceiling tile mounted, attached to a round fixture junction box or single-gang
RACO switch box.
The sensor operates in ambient temperatures of 0° C to 40° C, with a
maximum of 90% non-condensing humidity.
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. Reference
Lens Masking on page9

DIP Switch Settings
DIP switches on the rear panel of the Vacancy Sensor
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.
DIP Switch 2
DIP switch 2 enables “Custom Config” which
instructs the sensor to use settings that are configured using the ElahoAccess
Mobile App. This setting is Off by default.
•
When “Custom Config” is set to Off, the default position, local DIP
switch settings for Vacancy Timeout and Enable PIR LED are used.
Sensor actions can be adjusted using the program [Mode ] button.
•
When “Custom Config” is set to On, all other local DIP switch settings
are ignored. Instead, the settings made by the ElahoAccess Mobile
App for Vacancy Timeout and Enable PIR LED are used.
DIP Switch 3&4
DIP switch 3 & 4 set the “Vacancy Timeout” to 5, 15, 30 minutes, or Auto.
See
Vacancy Timeout on the next page
.
•
5 min = Switches 3 and 4 are Off.
•
15 min = Switch 3 is Off and Switch 4 is On (default).
•
30 = Switch 3 is On and Switch 4 is Off.
•
Auto = Both switches are On. See
Auto Vacancy Timeout on the next
page
.
DIP Switch 5
DIP switch 5 enables/disables the red PIR detection LED. When the switch is
Off, the PIR LED disables unless it is in Walk Test mode. When set to On, the
red PIR LED will illuminate the sensor lens when movement is detected. The
default position is On.
DIP Switch 8
DIP switch 8 provides a “Restore Defaults at Boot” function. The factory
defaults are restored by setting this DIP switch On, and cycling power to the
station. The default position is Off.
Note: DIP switches 1, 6, and 7 are not currently used and are reserved
for future development. Leave them at their default Off setting.

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 LED
illuminates for one minute for calibration and warm-up, and then returns to
normal operation.
Configuration
Basic Configuration Mode
When the Vacancy Sensor is in Basic config mode (DIP switch 2 set to Off), the
sensor will activate a Space Off command when vacancy is detected.
Custom Configuration Mode
When functionality other than Space Off is required, place the sensor in
Custom config mode (DIP switch 2 On). Customization of the Vacancy Sensor
and all actions are configured using the ElahoAccess Mobile App.
For more detailed information about custom configuration options available
for the Vacancy Sensor using ElahoAccess, reference the ElahoAccess Mobile
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). 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
to help prevent false vacancy detection. During this grace period, if the sensor
detects occupancy, it will restore the previous lighting condition.
Auto Vacancy Timeout
The “Auto” vacancy timeout setting varies vacancy the timeout between
5 and 30 minutes depending on how often it identifies an occupancy trigger
after a vacancy timeout occurs (during the grace period).

Lens Masking
Lens masks are provided in the packaging for your convenience, used to block
a section of the lens from detecting vacancy.
1.
As needed, trim the lens mask to
fit the desired area to be blocked.
2.
Gently press down on the sensor
lens, which will give only slightly,
and insert the lens mask.
3.
Rotate the lens mask around the
dome to block the required area
from sensing.
PIR Detection
The PIR detection automatically adjusts its sensitivity to eliminate nuisance
tripping. When the sensor powers on, the red PIR LED illuminates for
approximately 60 seconds to identify “Power Up” state. Sensor configuration
is not allowed. During this time, no events are triggered.
Test
Vacancy Sensors offer a Walk Test mode which shortens the vacancy timer to
ten seconds, allowing for simple and quick verification of the sensors
coverage and range in the installed space.
Auxiliary
