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).

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
