7.0 - CONNECTIONS TO ARM/DISARM THE SYSTEM
Alarm system 933MH can work either via CAN-BUS or via the Gemini remote control (art. 938).
Both arming/disarming modes are described here below.
6.0 - VEHICLE CODE PROGRAMMING
The system must be configured according to the specific vehicle model on which it is to be installed.
To help you understand the coding procedure, here below is an example illustrating the configuration
procedure.
In this case the code used is 1-0-3 which hypothetically corresponds to a “FIAT XXXXX”.
Press the vehicle remote control lock/unlock buttons to make sure the alarm system works properly.
Eventually disconnect the 8-pin connector and reconnect it after a few seconds.

When the last digit is entered, the alarm system “repeats” the entered code.
Either the vehicle original remote control or the Gemini remote control can be used to arm/disarm the
alarm system.
In this case, arming/disarming and alarms are managed via CAN BUS line. Only the alarm system
CAN BUS wires need to be connected to the vehicle CAN BUS wiring (see available diagrams at:
www.gemini-alarm.com).
This type of connection allows arming/disarming the system and locking/unlocking the vehicle doors
via the Gemini remote control (art. 938).
No particular connection is needed since the alarm system comes with a vehicle-specific wiring
harness.
7.1 - OPERATION VIA CAN BUS
7.2 - OPERATION VIA GEMINI REMOTE CONTROL
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-alarm.com.
The alarm has an indicator LED 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 previously inserted code remains stored.
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.
In either case, repeat the whole procedure.

Connect the wiring harness connectors to the alarm connectors.
Press and hold the button shown below until the LED lights up.
Release the button, the LED switches OFF.
After 3 to 4 seconds, the LED starts flashing; count the flashes.
In this case press the button at the 1st flash which corresponds to number “1”.
Again after 4 seconds, the LED starts flashing for the second time.
Press the button at the 10th flash which corresponds to number “0”.
After 4 more seconds, the LED starts flashing for the third time.
Press the button at the 3rd flash which corresponds to number “3”.

During an alarm event, the system cannot be disarmed via the Gemini remote
(art.938) but only with the vehicle original remote control.
