All models of the communicator are equipped with anti-tamper devices that protect
against unauthorized opening and dislodgement of the enclosure containing the PCB.
The Nexus and Nexus/G models are equipped with a buzzer for confirmation signals
programmed for any events related to programming from the control panel of the
Nexus board (for example the confirmation of call or SMS commands).
The Nexus/3GP model has internal batteries (supplied, description of the parts, [O]),
which ensure the correct functioning of the signals and transmissions from the device in
the absence of the power supply from the BUS (for example, in the case of wire-cutting
or tamper).
Despite the presence of batteries with sufficient charge, the power supply from the BUS
is required to switch on the Nexus/3GP.
The screw terminals for the connections (description of the parts, [A]) are described
below:
