7. Factory setting
The ‘FS20 PIRI-2’ is immediately ready for use and configured with the following factory default
settings:
•Channel 1 activated (ON)
• Activation also in lighted areas (dawn/dusk switch function inactive)
• Receiver on-time triggered by movement in front of the detector: 1 minute, then load is
switched off (transmit command).
• If further movements are registered during this minute, a new power-on command will be
transmitted, at most every 24 seconds, thereby restarting the 1-minute on-time (transmis-
sion interval).
•Channel 2 is inactive (OFF).
The terms printed here in bold are the adjustment criteria for each channel,
whose programming is described separately in the following user manual.

8. General notes on installation
• The front coverage lenses of the ‘FS20 PIRI-2’ are supplied with 4 detection levels with 9
upper, 8 middle, 5 lower and 2 creep zone segments. This enables a detection angle of 90°
to be achieved at a range of up to 12m.
• For additional security, the ‘FS20 PIRI-2’ is equipped with so-called ‘creep protection’ so
that an intruder cannot ‘creep’ under the detection area of the main lens. An additional
integrated lens is directed downward, under the main detection area.
This mini dome lens has 17 segments which cover an area of 3.75m x 3.75m when installed
at a height of 2m.
• In order to avoid unnecessary activation by household pets, keep them away from
protected areas when possible. If this is not possible, try adjusting the height to allow the
device appropriate coverage. Cover the creep zone where appropriate.
Please remember that household pets may also jump on, for instance, cabinets or chairs
and in so doing, arrive in the detection area. Choose a suitable installation location.
• To minimize false alarms, the PIR detector must not be installed where it may be exposed
to direct sunlight, car headlamps or similar, nor near heat sources (for example over
heaters).
The detection area should be aimed at a wall or on the floor, but not directly on windows,
heaters or other sources of heat.
• The performance of the detection is dependent upon the temperature difference between
the moving object and the respective background.
• Detection through glass is not possible (in that case, the IR sensor only recognises the
temperature of the glass).
• Please remember not to install the ‘FS20 PIRI-2’ directly on or near large metal objects
(heating, aluminium laminated board walls, etc.) because this reduces the radio range.

9. Installing the ‘FS20 PIRI-2’
a) Installation with wall bracket
The PIR motion detector is equipped with a bracket that is suitable for installation on a wall or
ceiling. Because the detector may be adjusted more than 45 degrees when in the bracket, the
detection area may be set at almost any angle from the wall and may also be further adjusted
after installation.
The ceiling installation option enables the device to be freely mounted within the room to avoid
common traffic paths within the detection area, for example, in a hallway.
• Select an appropriate installation location for the PIR motion detector in the monitored
room.
• Pull the wall/ceiling bracket up and off the base device of the PIR motion detector (1).
• Position the bracket in a suitable location on a wall or ceiling in the room.

• The location of the drill holes on the wall or ceiling can be marked through the visible screw
holes in the bracket.
For wall installation (2a) use both holes in the wall bracket.
For ceiling installation (2b) a hole needs to be drilled in the middle of the top of the bracket.
Make sure that the wall or ceiling can support the device at the marked drill hole
locations and avoid all electrical, gas, water and drain lines.
• Drill each 5mm hole at least 35 mm deep and insert 2 appropriately sized dowels.
• Position the wall/ceiling bracket over the drill holes and fasten it in place with the screws.

c) Opening the battery compartment
To open the battery compartment, first pull the wall/ceiling bracket in an upward direction (A).
Then slide the battery compartment cover upwards (B) and remove it (C).
d) Inserting the batteries
The PIR detector requires 3 size AA batteries. We recommend using
high-quality alkaline batteries to ensure longest possible battery life.
• Remove the battery compartment cover as described on the
previous page.
• Ensure that the 4-way DIP switch settings in the centre battery
compartment reflect the desired operating modes and if neces-
sary, set them as described in section 13 (Individual settings).
• Insert the batteries in the battery compartment observing the
correct polarity (plus/+ and minus/-, see figure on right).
• The battery compartment remains open.
After inserting the batteries, the device needs about 75 seconds before it is
ready for use. Within this time no motions will be detected.

10. Initial operation
a) Quick installation with factory settings
The motion detector is immediately ready for operation with the factory default settings
described in section 7. The transmission signals are encrypted using a house code that is
randomly assigned when the batteries are inserted and the address group 11 (control of
several receivers with one transmitter possible).
For the initial operation of the transmission path to the receiver, the house code and the
addresses must first be transmitted to the receiver.
• Set the respective receiver, according to the instructions in its user manual, to the address
programming mode.
• Press the ‘2’ button (channel 2: button ‘4’) on the keypad of the ‘FS20 PIRI-2’.
• The receiver’s indicator LED goes out.
• Test the switch function by briefly pressing the ‘2’ or ‘1’ buttons (channel 2: button ‘4’ or ‘3’)
on the ‘FS20 PIRI-2’. The receiver should switch on and off.
• Now the ‘FS20 PIRI-2’ is ready for operation with the factory settings.
• If you do not wish to set any further individual preferences, close the battery compartment.
• Place the device from below into the wall/ceiling bracket. It must audibly lock into place into
the wall/ceiling bracket.
b) Function test
You can adjust the detection area of the motion detector and thereby customise it for your
individual needs.
For this purpose, proceed as follows:
• Approach the detector by crossing back and forth across the detection area.
• When the detector detects you, it activates the status LED and the receiver.
• To individually optimise the detection area, the PIR motion detector can be adjusted when
in the wall/ceiling bracket.

16
At east one channel must be active in order to control the function and detection
area of the ‘FS20 PIRI-2’ with the internal LED display.
This means that at least one channel of the DIP switch must be active and not
set to ‘Switch on at twilight’ (DIP switch 2 or 4, setting described in section 13
b), if the brightness currently in the environment is higher than the programmed
brightness threshold.
Aside from this, the programmed transmission interval (factory setting: 24
seconds) of the respective channel must be observed, as this reduces re-
peated triggering with too short intervals.

17
11. The FS20 address system
The FS20 address system is based on a house code which allows a number of radio-controlled
systems to be operated simultaneously.
256 different addresses can be set within a house code. These addresses divide into four
address types with 225 individual addresses, 15 function group addresses, 15 local master
addresses and a global master address.
One address from each address type can be assigned to each receiver. This means that each
receiver can respond to up to four different addresses, but only ever to one address per
address type.
If you need a receiver to respond to more than one transmitter, you can program the
transmitters to the same address or, if different transmitter address types have been set, you
can program the receiver consecutively to these different addresses.
The individual address types have the following functions (this explanation applies globally to
the entire FS20 system and not just to individual components):
Single addresses
Each receiver should be set to a single address so that it can be controlled separately.
Function group addresses
Several receivers are defined as a functional unit by being assigned to a function group
address. If, for example, all the lamps in a house are assigned to a function group, then all the
lamps in the entire house can be switched on or off by pressing one button.
Local master addresses
Several receivers are spatially defined as one unit and controlled via the local master address.
If, for example, all the receivers in a room are each allocated to a local master address, then
all you need to do is press one button when leaving the room to switch off all the consumer
loads in the room.
Global master address
Several receivers are assigned to the global master address and are jointly controlled via this
address. All the consumer loads can easily be switched off simply by pressing one single
button when leaving a house, for example.
This address system opens up a variety of possibilities.

18
You can even implement access authorisations; by assigning three gates to different single
addresses and a joint function group (‘gates’), for example.
Several people can then each be given a hand-held transmitter with a relevant single address
for one garage door, while all the garage doors can be opened via a hand-held transmitter with
a programmed function group address or all the doors can be automatically closed in the
evening via a FS20 timer.
The various address types and addresses are only set on the transmitter and these settings
are transmitted to the receivers via the address assignment.

19
12. Integrating into the address system
The house code, an address group and a subaddress are used for coding the transmitters and
their individual buttons. You can also use special address group assignments to program the
remote control, in this case the ‘FS20 PIRI-2’, as a local or global master.
To enter the 8-digit house code, the 2-digit address groups and the 2-digit subaddresses, the
‘1’ through ‘4’ buttons are used (refer to figure in section 9 b) or 12 a) for assigning buttons to
numbers; the status display/programmable LED is visible from the start through the main lens).
This addressing makes 225 single addresses, 15 function groups, 15 local master addresses
and 1 global master address available for use by the ‘FS20 PIRI-2’ within each house code.
a) Setting the house code

When the batteries are first inserted, the device
sets a randomly chosen house code.
The house code can be changed as follows:
• Press buttons 1 and 3 and hold them down for
5 seconds, until the indicator LED begins to
blink slowly, around once a second.
• Enter the eight-digit house code of your sys-
tem using buttons 1, 2, 3 and 4. This code must
be identical for all the remote control transmit-
ters in the same wireless control system (as a
precaution, make a note of this code and keep
it safe), for example 12341234.
• The programming mode ends automatically
once you have entered the eighth digit. This is
indicated by the status LED going out.
The house code applies to both channels of
the ‘FS20 PIRI-2’ simultaneously!

b) Setting the addresses
A channel’s address comprises a two-digit address group and a two-digit subaddress.
The address group ‘11’ is factory set for all channels.
If several transmitters are to be operated at the same time and control different receivers, then
different addresses need to be set on the transmitters.
