Fibaro is a system that does not require any additional conductors; 
it is based on the Z-Wave technology. Fibaro offers a wide array of 
advantages in comparison to other, similar systems. In general, 
radio-based systems establish a direct connection between the 
receiver and the transmitter. The radio signal is attenuated by every 
obstacle along its path (in the household e.g. walls, furniture, etc). 
In the worst case the radio system ceases to function. The 
advantage of the Fibaro System is the fact that the devices act not 
only as a signal receiver and transmitter, but also as a signal 
repeater. If a direct radio link between the transmitter and the 
receiver cannot be established, the connection will be carried out 
with the use of other devices participating in communication.
II Sensor Installation:
1.Connect Fibaro Door/Window Sensor according to the 
   appropriate diagram (if necessary)
2. Place battery inside the Sensor's casing,
3. Include into the Z-Wave network.
4. Install Fibaro Door/Window Sensor observing diagram 4,

GLOSSARY OF TERMS: 
                                                                                                                               
• INCLUSION - the device sends out a Node Info frame, which 
  makes it possible to add it to the Fibaro System (Home Center 2),
• EXCLUSION - remove the device from the Fibaro System,
• ASSOCIATION - controlling other devices included in the Fibaro 
  System,
• Multi Channel Association - controlling other multi-channel 
  devices included in the Fibaro System
3. Controlling the Fibaro Door/Window Sensor with 
the Home Center 2 Controller
                                                                                                                               
The Door/Window Sensor is a multichannel device. This means 
that it is equipped with an independent input circuit and a 1-wire bus 
allowing it to be connected to a DS18B20 temperature sensor. As a 
result, each device is represented by an independent icon in the 
System.
2. Resetting the Fibaro Door/Window Sensor
There is one way to reset the Fibaro Door/Window Sensor. The 
procedure cleans its EPROM memory, including the main controller 
and Z-Wave network data.
To reset the Fibaro Door/Window Sensor please follow below 
instructions:
1) Take off the Sensor's cover and remove battery. Make sure the 
    TMP button is intact.
2) Touch the Sensor's body with a magnet,
3) Insert the battery,
4) Remove the magnet from the Sensor's body,
5) Remove the battery
6) Re-install the battery,
7) Reset will be confirmed by double LED blink.
III Fibaro Sensor Start-up
1.Installation of the Door/Window Sensor
STEP 1 
Install the device observing the Figure 4 for correct positioning of 
the Sensor and the magnet. Close the Sensor's casing.
[Inclusion/Exclusion] of the Fibaro Door/Window Sensor [to/from] 
the Z-Wave network.
STEP 2 
The Fibaro module must be in range of the Home Center 2 
controller, because the procedure of inclusion to the Fibaro System 
requires direct communication with the controller.
 
STEP 3 
Locate TMP button, which allows for proper inclusion of device.
The Fibaro Door/Window Sensor has a one, 
potential-free IN input. IN input status may be 
modified through the Sensor itself or by sending 
GND signal to IN (diagram 3). If the Door/Window 
Sensor will be used only as a binary sensor, do not 
install the magnet.

Fibaro is a bidirectional wireless system. This means the signal is 
not only sent to the receivers, but also the receivers send feedback 
confirming the reception of the signal. This also confirms the 
condition of receivers, which allows us to check whether or not a 
device has actually been switched on. The safety of transmission of 
the Fibaro System is comparable with a wire-linked bus system. 
Fibaro operates in the free band for data transmission. The 
frequency depends on the radio regulations in each individual 
country. 
Each Fibaro network has its own unique network identification 
number (home ID), which is why two or more independent systems 
may be installed in a single building without any interference.
Although the Z-Wave technology is fairly new, it has already been 
accepted as an official standard, just like Wi-Fi. Numerous 
manufacturers from various fields offer solutions based on Z-Wave 
technology, compatible with one another. This makes the system fit 
for the future and allows for further development. For more 
information go to www.fibaro.com.
Fibaro establishes a dynamic network structure. From the moment 
of start-up, the location data of respective devices of the Fibaro 
System is updated automatically, in real time, by confirming their 
condition in the working mesh network.
The DS18B20 temperature sensor may be installed 
anywhere where very precise temperature readouts 
are necessary. If adequately protected, the 
DS18B20 sensor may be installed in humid 
conditions, under water, sealed in concrete or placed 
under the floor.
i
USING DS18B20 TEMPERATURE SENSOR:
Metal surfaces in close vicinity (e.g. metal switch 
boxes, metal door trims) may impair the reception 
capability!
i
The antenna should be placed above the battery. 
Never cut, shorten or bend the antenna. Its length is 
suited ideally to the band at which the system 
functions.
i
NOTE! 
Every time any changes are made to the 
configuration of TP and TD lines (1-wire), i.e. when 
DS18B20 sensor is connected/disconnected, it is 
necessary to execute the procedure of exclusion 
and repeated inclusion of the sensor module to the 
Z-Wave network. The system will enter into the 
learning mode only after connected DS18B20 
sensor has been detected (about 10 s).
i
NOTE! 
Do not connect sensors other than DS18B20 to the 
1-wire line (TP and TD terminals).
i
NOTE! 
It is prohibited to connect the TP and TD lines to 
devices not compatible with the 1-wire protocol.
i
NOTE! 
Resetting the device memory doesn't remove it 
from the Z-Wave network's main controller 
memory. To be able to re-include the device into the 
Z-Wave network please exclude it first. Exclusion 
may be performed either before or after the reset 
procedure.

The Fibaro Door/Window Sensor is added to the network by quickly 
pressing the TMP button three times (the button is located on the 
underside of the device, inside its casing).
STEP 6  
Correct inclusion of the device to the network will be signalled by 
the Home Center 2 (see: Home Center 2 controller operation 
instructions).
NOTE! 
Fibaro Door/Window Sensor has two TMP buttons 
- inside and underside the casing.
During normal operation both TMP buttons must be 
secure. Do not use the sensor with opened casing.
i
MAGNETIC
SENSOR
NOTE! 
Door/Window Sensor is equipped with a built-in 
LED. LED blinks each time Door/Window Sensor 
changes its state. LED blinking slowly = correct 
inclusion. LED blinking rapidly = inclusion error.
i
NOTE! 
TMP button, located on the underside of the 
device, has two functions:
1. sets a device into the learn mode (Include to / 
Exclude from a Z-Wave network),
2. tamper button. After correct installation (fig. 5 
and 6), removing the whole sensor from its location 
or opening its casing may release the TMP button 
and trigger an alarm. If the TMP is to serve as a 
tamper button, association for II-nd association 
group must be configured (optionally, use the 
Parameter 13).
i
BATTERY USE:
The Fibaro Door/Window Sensor's battery life is up 
to 2 years, on default settings.
Current battery level is displayed in the Home 
Center 2 configuration interface. If a battery icon 
turns red, it means the battery needs replacement. 
In order not to trigger an alarm when replacing the 
battery, II-nd association group must be deleted 
and the Sensor's configuration must be changed to 
default, prior to the battery change.
