The Wall Switch Sensor is a wall mount occupancy sensor with integrated wall
switch that transmits occupancy state and switch acons wirelessly. The OWS
is a no-neutral conductor powered device connecng to line voltage and earth
ground. The OWS is referred to as a sensor throughout this document.
The OWS is designed for small oces, boardrooms or other small enclosed
spaces which require a wall switch and occupancy sensor. The OWS ts well
in applicaons where energy codes require the lights to be manually turned
ON and automacally OFF with vacancy. When used with Echoex Soluon’s
dimming lighng controllers, the switch also provides manual dimming control
of the lights. Echoex controlled receptacles can also be automated with the
OWS so plug loads operate ON or OFF with the current occupancy state.
The OWS communicates occupancy state and switch actuaon wirelessly
to Echoex controllers. The OWS models include a single method (PIR) or
a Dual Technology method of occupancy detecon using a PIR sensor and
audio interface (any reference to audio in this guide implies DT model only).
The combinaon of PIR sensor and audio sensing ensures posive occupant
detecon. Passive microphone technology provides full coverage of audible
human acvity across the enre PIR detecon range. Innovave noise ltering is
used to prevent false triggers that keep lights on in empty rooms.

The OWS wall switch sensor transmits using EnOcean equipment proles or
EEP’s. The OWS occupancy sensor uses EEP: A5-07-01 which transmits the
occupancy state (occupied or vacant) of the monitored space. The OWS switch
uses EEP: F6-02-02 to transmit the switch acon (On, OFF, Dimming).

If the monitored space is vacant for a period of me, only the PIR interface will
acvely monitor for occupancy. The audio interface will be disabled.
Once the PIR has detected moon, an occupancy telegram is sent immediately
and the audio interface is enabled.
Once the audio is enabled, two mers become acve that control this
interface.
1. The  is reset with each PIR event and denes the
maximum duraon which the audio remains acve.
If the mer expires, the audio will be disabled, no other acon will be
performed at that me. Once this mer has expired, only PIR triggers
can reset the mer to keep the light on. The default seng for the Audio
Enabled Timer is 60 minutes and is not congurable.
2. The  is reset upon each audio or PIR trigger at
the next occurrence of a telegram. It denes the me in which an occupancy
trigger (PIR or audio) must be detected to keep the audio acve. The default
value for this mer is 20 minutes and it is congurable to values of 5, 10,
15, 20 , 25 minutes or disabled. If the sensor occupancy mer expires, the
OWS will send out a vacancy signal and 40 seconds later the audio will be
disabled. The 40 seconds is grace me that allows an occupant to use sound
to reset the sensor occupancy mer and keep the light on.
The audio interface has a sound threshold that when exceeded, will maintain
the sensors occupied state while the mers are acve. The threshold is slightly
higher than the background noise level. The background noise level is averaged
over a 30 second window and ltered out. Any other sound louder than this
background level will trigger the audio.
For example: If a fan is running in the background while the space is occupied,
only a sound slightly louder than the fan noise will trigger the audio.
Either the PIR or audio can maintain the sensors occupied state with telegrams
being sent at minimum every 100 seconds. A red LED under the PIR lens will
blink when an occupied state telegram is sent. A linked Echoex controller has
an occupancy mer that is reset only when receiving occupied state telegrams
so the lights will remain on so long as the sensor connues to sense occupancy.
See the controller install guide for details on seng up this mer and
occupancy or vacancy modes of control.

The OWS-IR behaves similarly as the dual tech model; when vacant the PIR
monitors for occupancy. Once moon is detected and the occupancy state is
transmied to the receivers, the minimum period to the next telegram is > 100
seconds. If no moon is detected in 200 seconds, a vacant telegram is sent.
The sensor will transmit telegrams indicang vacancy every 1000 seconds.
So long as linked controllers receive an occupied state telegram before their
occupancy mer expires, the lights will remain on.
 the OWS
The OWS uses a PIR sensor that detects moon by measuring the infrared
energy given o by objects. The sensor is calibrated to detect the heat range of
human body temperature. The sensor has a lens that breaks the viewing angle
of the sensor into zones (movement zones). It is the movement of the infrared
energy moving in and out of a zone that denes occupancy.
The PIR interface cannot detect moon through solid objects including items
placed by a tenant such as le cabinets or bookshelves. Use the dual tech model
for spaces with visual obstacles between the sensor and areas of intended
moon.
The mounng locaon of the sensor is important as this will directly aect the
receivers recepon of the telegrams. Before installing, refer to the secons
in the guide detailing the installaon of wireless devices, layout ps and test
operaon modes.
You will require hand tools to gain access to the juncon box and remove any
cover plates or other hardware.

1. Locate the circuit breaker panel and turn o the power to the
circuit.
2. Remove any face plates from the juncon box.
3. Refer to the wiring diagram to connect the OWS to the line
power and ground. Use wire nuts on all connecons. The orange antenna
wire should be le in the antenna channel as shipped. Do not cut or cap
the antenna wire.
4. Restore power to the circuit.
5. Before installing the faceplate, the OWS should be linked to a receiver if
not done previously. Refer to the secon later in this guide on the linking
process.
6. Install the faceplate (not included). A non-metallic faceplate is highly
recommended.

Three LEDs (red, yellow and green) are located behind the PIR lens of the
sensor.
During normal operaon the red LED will blink when the sensor is sending an
occupied telegram.
The LEDs are also used during the selecon of the test modes and to indicate
status informaon.
See the Test Mode secon for more details.

The linking process requires the controller or receiver to be mounted, powered
and within range of the OWS to be linked. Each Echoex controller can support
up to 20 linked devices. Linking the OWS occupancy sensor and the OWS switch
will consume 2 of the receivers available linked devices. The controllers blink
code will indicate the number and type of objects linked and can be checked to
conrm the linking process completed successfully (Consult the manufacturer’s
controller/receiver install guide for more informaon).

Avoid locang transmiers and receivers on the same wall.
Avoid locang transmiers and receivers where the telegrams must penetrate
walls at acute angles. This increases the material the telegram must pass
through reducing the signal power.
Avoid large metal obstrucons as they create radio shadows. Place receivers
