REMOTE CONTROL

MODULE

GENERAL NOTES

The AC120 receiver unit is a compact module with many functions that can, as the
name indicates, memorize up to 120 radio commands.
It is managed by a microprocessor and it contains an EEPROM with a non-volatile
memory to which the first 60 radio commands can be linked.
A second EEPROM (art. ICO 161) can also be inserted. This is optional equipment,
to which a second series of 60 commands can be linked.
WARNING: during testing phases, besides the radio command supplied, a second
one has been inserted in the memory. Cancel it and program the radio commands
again.

EEPROM MANAGEMENT

The socket for the first EEPROM is located on the right-hand side of the circuit, above
the relay (see figure 1).

SOCKET 2 SOCKET 1

RELAY

Figure 1

The on-board relays have a double input C - N.O. - N.C.; they can be programmed for
impulse, step and timer.
It is also possible to select which of the remote control buttons to link to the relay
output.
The AC120 module can be linked to radio commands associated with various
GEMINI auto alarms (two-channel or four-channel) enabling you to use a single
transmitter to operate automobile components as well as an entrance gate or garage
door, as illustrated in the EXAMPLES section.
If you wish to add the second management EEPROM to the remote control unit, it will
be automatically recognised by the module; you only need to disconnect the power
input when you insert the EEPROM into its socket; when power is restored to the unit,
it will recognise the new situation and it will flash the LED two times.
The positions of the two EEPROMs can be inverted. However, the module will not
work if an EEPROM is fitted into socket 2 and socket 1 is left empty.

NOTE: Be careful how you insert the second EEPROM into its seat (socket),

otherwise it may be irremediably damaged. To avoid this, make sure you
insert the EEPROM with the half circle of the EEPROM coinciding with the half
circle of the socket (see figure 2 below).

DIPSWITCH COMBINATIONS

Note that the example given below is also applicable for the regulation of the
dipswitches of the 2nd output channel (relay).
DIP 1- OFF, ACTIVATION BY IMPULSES: pressing the remote control button, the
relative relay is excited for approximately ½ second.
DIP 1-ON DIP 2-OFF, TWO-POSITION ACTIVATION: pressing the remote control
button, the state of the relative relay is changed permanently. Pressing the same
button again, the relay returns to its initial position.
DIP 1-ON DIP 2-ON, TIMER ACTIVATION: pressing the remote control button, the
state of the relative relay is changed for a period of about 4 minutes. Pressing the
same button again, the relay excitation time is zeroed.
DIP 3-OFF - BUTTON LINKING: with the 4-button remote control, setting the dip­switch in this position, it is memorised as button 1 of the radio command

DIP 3-ON - BUTTON LINKING: with the 4-button remote control, setting the dip-
switch in this position, it is memorised as button 3 of the radio command

CANCELLING THE RADIO COMMANDS

The radio commands can be partially or totally cancelled.
Total cancellation cleans the memory completely, with the loss of all the data.
Partial cancellation allows you to eliminate only certain radio commands from the
memory.
Both procedures are described below:

If the EEPROM memory is full, the AC120 module, as it enters in the self-learning
procedure of a new remote control, will make the LED flash and not allow access to
the programming.

·Press the “LEARN” button on the module (see figure 5).

·Keep the button pressed until the LED goes off (10-15

seconds). If the button is released before the LED goes off, the
procedure will be invalidated.

If two EEPROMs are fitted on the module, both will be cancelled.
To cancel only one EEPROM memory, turn off the power to the AC120 unit and
remove the EEPROM that you do not want to cancel.
If this is fitted in socket 2, move the EEPROM to socket 1 and proceed with the
cancellation.
When you programme the radio commands, we advise that you keep a note the
progressive memorization number, so that you can cancel the single radio
commands.
The remote controls are divided into groups, from 1 to 10-group 1, from 11 to 20­group 2, from 21 to 30-group 3... and so on, up to group 12 (corresponding to the
120th radio command).

TOTAL

CANCELLATION

·Check the dipswitch settings on the module remembering that the new

radio commands will be memorised according to the settings of the
dipswitches.

·Press and release the “LEARN” button on the AC120 module (see

figure 5). The LED will flash once.

·Press one button of the learning radio command. The LED will flash

again.

PROGRAMMING THE REMOTE CONTROL

The remote control unit's self-learning can take be achieved in two ways, as

described below:

METHOD 1:

METHOD 2:

·Locate a remote control already coded.

·Check the setting of the dipswitches on the module remembering

that the new radio commands will be memorised according to the
settings of the dipswitches.

·Press contemporaneously, for 1 or 2 seconds, the buttons of a

remote control already coded for channels 1-2 or 3-4. The LED will
emit a series of short flashes followed by a longer fixed one.

·Press one button of the learning remote control. The LED will flash

one time.

a) Turn on the Module pressing the “LEARN” button. Wait 2

seconds after the LED has gone off; it will tell you how many
EEPROMs are fitted (one flash, one EEPROM, two flashes, two
EEPROMS).

b) Release the “LEARN” button; the LED will emit 5 long flashes.
c) Press the “LEARN” button repeatedly from 1 to 12 times to

select the group that the remote control to be cancelled belongs
to. The LED will emit a number of brief flashes corresponding to

the selected group.

NOTE: if you exceed the maximum number of memorisable
groups of remote controls, depending on the memories
installed, the procedure will start over from point b.

d) Press the “LEARN” button from 1 to 10 times to select the radio

command you want to cancel. The LED will emit a number of
flashes corresponding to the cancelled radio command.

e) Press the “LEARN” button. The LED will light up.

f) Keep the “LEARN” button pressed until the LED goes off. If you

release the button before the LED has gone off, the cancellation
will be invalidated and the procedure will have to be followed
again starting from point b.

PARTIAL

CANCELLATION

After completing the cancellation procedure, remove and restore power to the
module, so that it returns to its normal operating mode.

Configuring the programming of the remote control buttons as in figure 8, with a
single remote control, you will be able to command the automobile components ­buttons 1 and 2, an entrance gate - button 3 and the driveway lighting or a garage
door - button 4.
To connect lights to an automatic or controlled timer, see the table in the
paragraph “Setting and Management the Relay Outputs”.

EXAMPLES

The examples given below will show you how the AC120 remote control module
can be used.
The settings that can be made on the module and the possibility of using an
infinite number, if set in different ways, of a number of modules, will enable you to
handle a great number of peripheral units.

The programming shown in figure 8 implies the use of 2 AC120 units, both in the
same enviropment.
The use of the command modules is not, in fact, limited also to the code of a remote
control command to an automobile alarm.

BUTTON No3:

BUTTON NO4:

Figure 8

The programming shown in figure 7, implies the use of 2 AC 120 modules, one at
home and one at the company, keeping buttons 1 and 2 configured for the auto.
In fact, having 2 command modules available, these can learn the code of the same
radio command and therefore, be programmed in a different way.
The same can be done if you have three modules, for example, for a holiday home
and so on, for an infinite number of modules.
