DESCRIPTION OF THE MODULE GEMINI 7059.
GEMINI 7059 protects the vehicle detecting attempts to break into the passengers compartment
by the emission of an electromagnetic field (frequency = 2,45 GHz).
The working of the sensor is based on the reflection of the electromagnetic waves when a object,
made of a conductive material, is located on the field.
The measurement of the reflected waves can detect the intrusion and then trigger the alarm
device connected to the sensor.
GEMIN 7059 is insensitive to air movements (wind, thermal air drift, etc.), for this reason it's
suitable to be fitted on pick-up vehicles, convertible cars and vehicle equipped by a sliding
sunroof.
Due to the fact that the insulating materials are transparent to the electromagnetic waves it's
possible to fit the sensor module in a hidden position, e.g. under the passengers compartment
carpet.
FITTING INSTRUCTIONS.
In order to obtain the correct working of the sensor module it's very important to identify the
best fitting position depending on the vehicle model.
In any case, it's important to remember that, the complete protection of the vehicle internal
space can not be obtained using a high-frequency sensor module.
The sensitivity adjustment must be done in order to avoid false alarm triggering, due to objects
in movement outside the vehicle (e.g. people, other vehicles or motorbikes).
To increase the false alarms protection it's important to comply the following fitting rules :
a) the connection cable of the sensor must be fitted and routed far from the module case.
b) the module must be fitted far from coin holders or glove compartments.
c) avoid all metal mobile objects in the passengers compartment.
To find the proper fitting position, please see the fitting diagram contained in this fitting manual.
ELECTRIC CONNECTIONS.
The connection of the module to the alarm system is very easy as the wiring harness is equipped with a
proper connector.
SENSITIVITY ADJUSTMENT.
GEMINI 7059 is provided by a sensitivity adjustment control, by this it's possible to set the sensor
sensitivity from a MINIMUM value (NOT ZERO) to a MAXIMUM value.
To help the adjustment operation the module is provided by a RED led located on the top side of the sensor
case. This led is lighted for 4 sec. when an alarm condition is detected. (NOTE : between an alarm condition
and the following is present a delay time of 5 sec.).
ADJUSTMENT PROCEDURE :
1) Set the adjustment control to the MAXIMUM value (clockwise direction).
2) Close all doors, windows, boot and bonnet, then arm the alarm unit connected to the sensor module and
wait for the end of the arming delay time, or set on the DIAGNOSTIC MODE
3) Move the hands near the vehicle windows (lateral, front and rear) and make sure that the sensor does
not activate.
4) If the sensor activate reduce the value of the adjustment control (anti-clockwise direction), then repeat
the test described on the point 3).
5) If the test result is positive, (no false alarms detected moving the hands near the windows), disarm the
alarm unit and open one of the front windows.
6) Arm the alarm unit again, or set on the DIAGNOSTIC MODE, and check the correct alarm triggering
moving an arm inside the passengers compartment.
