1.2 INSTALLATION
EyeZen RF it is entirely powered through a battery. The communication with the other
devices of the installation is carried out through the RF antenna that incorporates inside.
Figure 1. EyeZen RF. Elements
The main elements of the device are described next.
Programming button (3): a short press on this button sets the device into the
programming mode, making the associated LED (4) light in red.
Note: if this button is held while plugging the battery, the device will enter the
safe mode. In such case, the LED will blink in red every 0.5 seconds.
Detection notification LED (1): emits a red light flash when the sensor
observes motion.
To get detailed information about the technical features of this device, as well as on the
installation process and on security procedures, please refer to the corresponding
Datasheet, bundled with the original packaging of the device and also available at
www.zennio.com.

1.3 DEVICE PROGRAMMING
Once the battery is connected, downloading both the physical address and the
application program will be possible. To do this, the EyeZen RF must be in “active”state.
Generally, EyeZen RF remains in a low consumption idle state in which it does not
respond to orders or reading requests, therefore, it is necessary to force it out of this idle
state in order to perform the downloading.
The EyeZen RF enters the active state and remains in the active state for 1 minute when
the programming button is pressed.
In addition, after power failure or programming the device will remain in the active state
for 10s.
Note: if the programming LED does not light up when the battery is removed and
reconnected, perform a longer power failure (at least 30 seconds).
1.4 START-UP AND POWER LOSS
During the start-up of the device, the detection notification LED flashes red for one
minute before the motion sensor is ready.
Furthermore, if the tamper and battery alarms are enabled, the state of these 2 alarms
will be sent after each reset.

2CONFIGURATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
parameters window of the device.
2.1 GENERAL
In “General” tab all the functionality of the device will be configured, with the exception
of the motion detection functionality, which will be configured in a separated tab.
Therefore, since this tab it will be possible configure the power of the radio frequency
transmission, the lens color, Heartbeat and two alarms:
Transmission power: sets the distance and the power of the radio frequency
links.
Lens color: sets the color of the lens of the device
Tamper: notifies whether the device has been tampered with by removing its
enclosure.
Battery: warns the user when the battery level is about to run out.
ETS PARAMETERISATION
From General screen it is possible to activate/deactivate all the required functionality.

Note: higher transmission power increases the transmission distance of the
EyeZen RF but also shortens battery life.
Lens Color [White / Black]. selecting the lens color that EyeZen RF has
installed, will allow a correct performing of the device.
Alarm: Tamper [enabled / disabled]: enables the object “Alarm: Tamper”
through which an 'Alarm' is sent when the battery cover is removed, and ‘No
Alarm’ when it is replaced
Note: the tamper alarm will be sent 5 times with a period of 2 seconds after
each change of state.
Alarm: Battery [enabled / disabled]: enables the object “Alarm: Battery
(Status)” through which a '1' is sent when the battery level is about to run out.
Note: the battery alarm will be sent periodically every day, while the ‘No alarm’
notification will be sent only once. After each device reset the battery state will
be notified
Heartbeat (Periodic Alive Notification) [enabled / disabled]: incorporates a
one-bit object to the project (“[Heartbeat] Object to Send ‘1’”) that will be sent
periodically with a value of “1” to notify that the device is still working (still alive).
Figure 3. Heartbeat
Note: the first sending after download or bus failure takes place with a delay of
up to 255 seconds, to prevent bus overload. The following sending match the
period set.
Note: with the aim of increase the battery life, Heartbeat will only be configurable
in days.

2.2 MOVEMENT DETECTOR
2.2.1 CONFIGURATION
EyeZen RF incorporates motion detector functionality, which consists in sending
objects to the bus whenever the device observes a moving body (or no longer observes
it) in the environment of the room where it has been installed. Also, it will be possible to
control the climate depending of the motion detection.
The operating principle of the motion detection is as follows, in general, the device will
remain in low power state in order to increase the battery saving. When a motion is
detected, it will be notified by means of the configured objects. Then, the device returns
to the low power state during the waiting time, which it is configurable, and in case of
detects new motions during these will not be taken into account.
After this waiting time has elapsed, a listening time starts where the device will again
detect motion and where two situations may occur:
No motion is detected during this time, therefore it is considered that there is no
one in the room and no detection objects are sent.
A new motion is detected during this time, therefore the detection state is
maintained, without notifying anything, starting the waiting time again and
restarting the operation explained previously
In any case, it is also possible to configure blind time to be counted from the transition
from detection to no detection transition, where during this time any motion will be
ignored.
For a better understanding, an operational diagram of the is added.

Figure 4. Operating principle of the motion detector
In the case of enable HVAC control, this functionality provides a filter to allow switching
on the unit only if motion is being detected on a continuing basis, which helps preventing
the switch-on of the climate system in case of exceptional or temporary movements.
This filter consists in a set of time windows, which allow switching to the Detection state
only if motion has been detected in all of them.
Example:a two 30-second window filter:
Immediately after the first detection, 30-second count of the first time
window will start, considering this window as overcome.
Once the first 30-second time count finishes, a second window begins. If
no motion is detected in this time, the process is aborted and does not
start over until a new detection takes place. However, if detections dotake
place during the second window as well, then the Detection state will be
adopted immediately.
Both the number of windows and its duration is configurable from ETS by enabling this
functionality, furthermore it is possible to send additionally different HVAC modes for
detection and no detection states.
In addition, EyeZen RF, allows any detected motion to be notified by means of the LED
detection indicator

Finally, it is also possible to set custom sensitivity values for the motion sensor. Factors
such as the motion speed and direction together with the distance to the device may
have a positive or negative effect the motion detection.

Table 1. Factors conditioning the motion detection
Therefore, low sensitivity may prevent the detection of slower and front movements,
especially at longer distances from the sensor. On the other hand, higher sensitivity
may saturate the detection, especially at shorter distances.

➢Observation Windows [1…3…255]: number of time windows in which
motion must be detected before switching to Detection.
➢Observation Time [1…30…255] [s]: length (in seconds) of each
observation window.
Waiting Time [60…150…255][s] [1…255][min] [0…18][h]: sets the value of the
waiting time during which motions will be ignored.
Listening Time [60…150…255][s] [1…255][min] [0…18][h]: sets the value of
the listening time during which motion will be taken into account in order to
establish the appropriate detection state.
Blind Time [0…255][s]: ]: sets the minimum period of time the channel will
remain under the “No Detection” state, even if motion detections are taking
place in the room, which will be ignored.
2.2.2 SENDINGS
In this tab it is possible to customise the sending for Detection and No detection states,
as well as, their periodicity and delay.
