I General Information on the Fibaro System:

HINT

Connections should be made specifically 

according to the diagrams presented in this 

manual. Incorrect connections may be hazardous 

or lead to device damage.

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.

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.

Diagram 3 - Example connection - momentary switch

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.

STEP 4

  

Set the Home Center 2 controller to the inclusion or exclusion mode 

(see: Home Center 2 controller instructions).

STEP 5

  

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.
