Dear Customer, the 931R12 is a universal CAN BUS alarm system which can also, with a simple 2
wire hook-up, be used forcentral door locking (onlyfor vehicles with negativepulse door locks).
This system features an integrated radio receiver and comes with a 2-button remote control which can
be used as an extra remote to lock/unlock vehicle doors and arm/disarm the alarm system. It does not
incorporate an immobilizer.
Please be aware of the following signs, intended for the installer or the user, which indicate particular
functions or connectionsas follows:
For the user.
This sign highlights useful information.
For the installer.
!
This sign indicates that the system will work according to the connections and the
programming selected or it simply provides useful installation tips.
2.0 - REMOTE CONTROL
If the required connections are made, the remote control arm/disarmbuttonscan also
lock/unlock the vehicle doors.
COMPLETE SYSTEM ARMING
When the batteries become too weak to operate the remote control, the LED will blink each time the
buttons are pressed.Replace batteries as follows:
Separate the plasticshells of the remotecontrol. Be careful notto damage the internalcircuit.
!
Remove the dischargedbatteries.
!
Insert the newbatteries in their housing,taking care not toinvert the polarity.
!
Close the plasticshells.
!
Try the remote controlto make sure itworks properly.

At the endof an alarm cycle,before another one starts,there is a 5sec. “neutral time”.
Every alarm generatesa maximum of ten30” alarm cycles foreach input and foreach arming.
3.6 - SYSTEM DISARMING
Press the unlock button on the vehicle original remote control or press button “2” on the supplied
remote control; system disarming is confirmed by 2 siren chirps
(if feature status has been configured)
and 2 flashesof the turn indicators.
An alarm condition is signalled by 5 acoustic signals (if feature status has been configured) and 5
flashes of theturn indicators.
Next paragraphlists the variousalarm causes and relativeLED
(3.7)signals.
3.7 - ALARM MEMORY
If, when disarming, the turn indicators flash 5 times and the alarm system gives 5 audio signals (if
feature status has been configured), it means that an alarm condition has occurred while away from
your vehicle. The causeof the last alarmcan be identified by the LED memory.
Turn ignition key “ON”;the vehicle status LEDblinks to indicate thelast alarm cause.
The optical signalsare repeated 3 times;to interrupt, turn ignitionkey “OFF”.
The various alarmcauses and relative opticalsignals are detailed inthe following table.
We recommend replacing thedefault PIN-CODE, factory setas 1-1-1-1, with a custom PIN-CODE.
To do so, proceedas indicated in theexample below, supposing the PIN CODE is 5-4-6-7.
If, while inserting the PIN-CODE, the LED flashes more than 9 times, the procedure will
be interrupted because of an invalid code number.

The system can be disarmed by entering the 4-digit emergency PIN-CODE as indicated in the
example below.
Please be awarethat the default PIN-CODEis factory set as1-1-1-1.
The example belowconsiders the PIN-CODE previouslyprogrammed “5-4-6-7”.

The 931R12 system can operate in various modes according to the vehicle on which it is installed and
connections that canbe made.
The alarm system can be managed via the vehicle CAN-BUS line and operate in combination with the
turn indicator flashes and/or the door lock motor units. The system automatically manages the
different arming/disarming signals.
Refer to theinstallation specifications for theavailable connections for eachvehicle.

12.0 - VEHICLE CODE PROGRAMMING
I”.f the system is intended towork via CAN-BUS, it must be configured accordingto the vehicle on which
it is installed.
To help you understand the coding procedure, here below is an example illustrating the configuration
procedure.
In this casethe code used is1-0-3 which hypothetically corresponds to a “FIATXXXXX
A separate leaflet, included in the alarm packaging, lists all the available vehicles
(codes are updated at packaging time).

Up-to-date information on supported vehicle models can be found at: www.gemini-

When the last digit is entered, the alarm system “repeats” the entered code.
1 FLASH AND A
SHORT PAUSE
10 FLASHES AND A
SHORT PAUSE
3 FLASHES
The system has a LED indicator that signals any wrong vehicle code inserted.
The code must range between 100 and 235 otherwise the LED on the unit blinks
repeatedly and the procedure is interrupted.
!
The procedure is also invalidated if the LED blinks more than 10 times.
In this case there is no optical warning, the procedure is simply interrupted.
Connect the harness connectors to the alarm connectors.
After 3/4 seconds, the LED starts a flashing sequence; count the flashes.
Press the button at the 1st flash, which corresponds to number “1”.
Press the button at the 10th flash which corresponds to number “0”.
The previously inserted code remains stored.
In either case, repeat the whole procedure.

13.0 - SELF-LEARNING OF TURN INDICATOR FLASHES
In order to arm/disarm via the turn indicators, the system must learn the vehicle lock (arm) and unlock
(disarm) signals.
Connect the WHITE-ORANGEwire to the turnindicators and proceed asfollows
