INTRODUCTION
When a radio control system is used the transmitter sends a “signal” to the receiver that, if recognised
as valid, activates the output relays.
In view of the fact that a transmitter should activate only its own receiver and not that of your
neighbour, you have to codify the signal sent which means that each receiver will recognise its own
signal and not others that might be similar.
In traditional systems the code can be selected by means of a set of microswitches in the transmitter
(offering only a few thousand combinations) or it can be programmed directly during production (in
this case you have a few million different code numbers available); however, the code number is
fixed which means that each time it is transmitted the same signal is sent.
The fact that the code is sent by radio and that it is always the same does, unfortunately, offer the
possibility to people who are up to no good to receive (even at a distance) and record the signal
which they can then use as the “key” to open your door.
The “FLOR” system uses a principle that makes your radio control extremely safe.
A technique called “Rolling Code” is used that changes a part of the code each time it is transmitted
following a predefined sequence; the code is masked with appropriate mathematical functions so
there is no logical connection between two consecutive codes. The receiver is always synchronised
with the transmitter so it will accept only the programmed code sequence. It is completely
useless to try and copy the signal transmitted with this system because once the code has been
“used” the receiver will only recognise the next one.
From what we have described here it appears essential to keep the code sent by the transmitter and
the receiver perfectly synchronised but this is not completely true because there is a code window
that lets the receiver accept, in sequence, the next code plus a certain number of subsequent codes
without ever accepting a code that has already been used!
Even if you exit from the code window, the receiver is designed to re-synchronise itself automatically:
when it receives the first code there will be no activation but only storage of the code sent; when the
next signal is sent it will be synchronised and activate the outputs. Automatic re-synchronisation is of
course possible only if the codes are received following the established sequence.
DESCRIPTION
The system comprises:
• 1, 2 or 4 channel transmitters (FLO1R, FLO2R, FLO4R), and 2 channel (VR of the VERY series)
• Receivers with a terminal connection, 1 or 2 channels (FLOX1R, FLOX2R, FLOXB2R)
• Receivers with plug in connections, 1 or 2 channels (FLOXIR, FLOXI2R)
• Modular receivers (FLOXM220R, FLOXMR)
• Memory card that contains the codes (BM60, BM250, BM1000 - 15, 63 or 255 codes maximum respectively)
• Aerial (ABF - ABFKIT)

INSTALLATION
Transmitters:
The transmitters are ready to use, each with
their own code number set during
construction. To see if they are working
properly simply press one of the keys and
check that the red LED is flashing, indicating
transmission.
The transmitter has a device built into it that
controls battery state: press one of the keys
and if the battery is fully charged the LED will
give an initial pulse followed immediately by
the transmission signal. If the battery is partly flat the LED will give the first pulse and start
transmitting only after half a second.
In this case we advise you change the battery as soon as possible.
If, on the other hand, the battery is completely flat the LED will flash at half-second intervals without
transmitting and the battery must be changed immediately.

Selecting the channel on the transmitter:
It is possible to modify the key-channel connection on the FLOR1 and FLOR2 versions.
For key 1, simply cut the track that linked it to the 1st channel, as shown in Fig. 1A, and connect one
of the other pads on the right with a drop of solder to link it to the 2nd, 3rd or 4th channel. Do exactly
the same for the 2nd key, as shown in Fig. 1B. On VR the transmitters in the VERY series, the
key/channel association cannot be modified.

Receivers with terminals:
Receivers with terminals are universal in their use. The container, which can be fixed with screws or
using the adhesive on the bottom, provides the circuit with good protection.
Wire up following this sequence:
1-2: POWER: from 10 to 28 V direct or alternate.
3-4: 1st RELAYOUTPUT: free contact of a normally open relay.
5-6: 2nd RELAY OUTPUT: free contact of a normally open relay (only on 2-channel receivers).
1-2: AERIAL: aerial signal input.

Plug in Receivers:
Plug in receivers are to be plugged directly into NICE units; once plugged in they are ready to work
as all the electrical signals (power, aerial and outputs) have their own place on the unit.
POWER:
from 20 to 28 V direct or alternate,
normally supplied by the unit.
1st RELAYOUTPUT:
free contact of a normally open
relay, used for unit command.
2nd RELAY OUTPUT:
free contact of a normally open
relay available on specific unit
terminals (only on 2-channel
receivers).
AERIAL:
aerial signal input, on specific unit
terminals.

Memory card
Each transmitter has its own code number (selected from more than 250 million) that distinguishes it
from all other remote controls. The receiver can receive all the codes but is activated only if that
particular code is on the list of “authorised”code numbers on the memory card.
The receivers are supplied with a BM250 memory card that can contain a maximum of 63 code
numbers (63 remote controls are the maximum quantity). A BM60 memory card can also be used
with a maximum of 16 code numbers or an BM1000 with a maximum of 255 code numbers, in
substitution of the BM250 card supplied with the unit. When powered, the receiver displays the type
of memory used: if a BM60 memory card is being used the LED will flash briefly; if a BM250 memory
card is being used instead, the LED will flash twice, while if an BM1000 memory card is being used
the LED will flash three times.
All the codes are stored in the memory, so when maximum security is required the code learning
function must be disabled (this can also be done remotely). After the code numbers of the remote
controls being used have been entered, break the track indicated by an arrow (Fig. 4). If, later on,
you wish to enter other code numbers, join the two pads with a dot of solder (Fig. 5)
ATTENTION!!: Turn the receiver off before pulling out or plugging in a memory card.
This is a “hardware”type of disabling function, very simple to do but, consequently, very easy to undo
by an intruder.
There is also another type of disabling function, a “software”type, more difficult to manage but
extremely secure in that only a previously authorised remote control can be used to restore it (see
activating/deactivating the 2nd disabling function).
Still on the subject of safety, there is another even more secure type of disabling function, which is
controlled by a “PASSWORD”. Only a portable accessory BUPC manages this function.

Selection of the relays on the channels
Each receiver can recognise all 4 transmitter channels (channels = keys). Association of the output
relays to the channel required is done via a jumper that has to be plugged in.
