OPERATION MANUAL

UNIVERSAL BINARY SENSOR 

 FGBS-321-USA-A-v1.01

The Universal Binary Sensor is a wireless module that makes it 

possible to improve the functionality of any sensor with a binary 

output by allowing it to communicate with the wireless network 

Z-WAVE and the FIBARO building intelligence system. Moreover, 

the module allows for wireless communication between the system 

and the DS18B20 temperature sensors. The device can service up 

to two binary sensors and up to four DS18B20 temperature sensors. 

The Sensor was designed for installation in the housing of a sensor 

or another device, the functionality of which we wish to improve.

The Universal Binary Sensor may be used whenever wireless 

collection of data from sensors is required. Once additional safety 

housing have been installed, the Sensor can also be used in areas 

with high humidity and high temperature. The Sensor’s main function 

is the integration of the wireless Fibaro System with the existing 

wire-based and wireless alarm and measurement systems. As an 

element of the safety system the device is transparent for parametric 

alarm lines.

The outputs of the device should not be loaded with 

a current value exceeding 150mA

Connections should be made specifically 

according to the diagrams presented in this 

manual. Incorrect connection may lead to hazards.

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.

Fibaro is a bidirectional wireless system. This means that 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 radio regulations in individual country . Each 

Fibaro network has its own unique network identification number 

(home ID), which is why it is possible to co-operate two or more 

independent systems 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, which are 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.

P – (POWER) – power supply conductor, red

GND - (GROUND) – ground conductor, blue

IN1 – input no. 1 

IN2 – input no. 2 

TP – (TEMP_POWER) – power supply conductor of the DS18B20 

temperature sensor, brown (3.3V)

TD – (TEMP_DATA) – signal conductor of the DS18B20 

temperature sensor, white

ANT – antenna, black

OUT1 – output no. 1 assigned to input IN1

OUT2 – output no. 2 assigned to input IN2

B – maintenance button (used to add devices to and remove 

devices from the system)

Only the B button starts the device’s programming 

process (Include/Exclude).

Condition of outputs OUT1 and OUT2 is dependent 

only on the condition of corresponding inputs, 

irrespective of parameter settings or addition of 

device to the Z-wave network.

Do not remove the protective layer surrounding the 

module. Make sure that no metal parts of other 

devices or conductors come into close contact with 

the installed Sensor.

It is prohibited to connect the TP and TD lines to 

devices that are not compatible with the 1-wire 

protocol. Unused lines should be left insulated.

Every time when any changes are made to the 

configuration of TP and TD lines (1-wire), e.g. when 

DS18B20 sensor(s) is (are) included/excluded, it is 

necessary to execute the procedure of exclusion 

and repeated inclusion of the sensor module to the 

central hub. It should be remembered that the 

system shall enter into the programming mode only 

once all the connected sensors have been 

detected (about 10 s).

• INCLUSION – the device sends out a Node Info frame, which 

makes it possible to add it to the Fibaro system (Home Center)

• EXCLUSION – removal of device from the Fibaro system

• ASSOCIATION – controlling other devices of the Fibaro system

• MultiChannel Association - controlling other multi-channel 

devices of the Fibaro system

The FGBS221 Sensor is a multi-channel device. This means that it 

is equipped with two independent input circuits and a 1-wire bus 

allowing it to be connected to four DS18B20 temperature sensors. 

As a result, each device connected to the Sensor is represented by 

an independent icon in the system.

After the Fibaro Sensor has been added to the network, it shall be 

represented by appropriate icons in the Home Center 2 controller, 

depending on the number of connected devices (3 – 7 icons).

In the event of including the Sensor without any sensors connected 

(or with sensors connected only to IN1 and IN2), the device will be 

represented by three icons. If DS18B20 sensors are also 

connected, the devices will be represented by additional 

temperature icons.

There are two procedures you can follow in order to reset the 

Fibaro Sensor.

Method I  

Resetting in the course of the procedure of excluding the Fibaro 

Module from an existing Z-wave network. Devices may be excluded 

with the use of a controller, which offers the option to exclude 

devices from or include devices to the Z-wave network (see: 

controller instructions).

  

Resetting by cutting off the power supply and re-connecting the 

power supply while holding down the B button – after 10 seconds, 

after another cut-off and re-connection of power supply the settings 

of the device will be reset.

 

Connect the device according to the wiring diagram shown in figure 

1. Engage the supply voltage.

[Inclusion / Exclusion] of the Fibaro Sensor [to / from] the Z-Wave 

network

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.

Recognition of B button, which allows for proper inclusion of device.

Setting the Home Center 2 controller to the inclusion or exclusion 

mode (see: Home Center 2 controller instructions).

The Fibaro Sensor is added to the network by quickly pressing the 

B button three times (the button is located in the center of the 

device).

Correct inclusion of the device to the network will be signaled by 

Home Center 2 (see: Home Center 2 central hub operation 

instructions).

The Sensor is powered with secure voltage; 

nevertheless, the user should be extra careful or 

should commission the installation to a qualified 

person.

Lay down the antenna as far as possible from 

metal elements (connection conductors, ring 

brackets etc.), in order to prevent any interference 

of the radio signal.

Metal surfaces in close vicinity (e.g. metal 

embedded boxes, metal door trims) may impair the 

reception capability!

You should not cut off or shorten the antenna. Its 

length is suited ideally to the band at which the 

system functions.

The DS18B20 sensor may easily be installed wherever very precise 

temperature measurements are required. Moreover, if proper 

protective measures are undertaken, the sensor may be used in 

humid environments or under water, it may be embedded in 

concrete or placed under the floor.

Do not connect other sensors than DS18B20 to the 

1-wire line (terminals TP and TD).
