Telemetry device
PR-SC4
The PR-SC4 device is one of the telemetry device
that the Prosa Infrastructure uses in order to
create an Internet Of Things. In this case, the
“Things” are supposed to be the dispenser of
beverages and cold room for goods storage.
The primary goal of the PR-SC4 device is to
communicate to the Prosa system diagnostic
parameters and eventually alarms related to the
temperatures of the storage equipment. To this
aim, the PR-SC4 can work in conjunction with the
electronic thermostat of the cooling equipment
when available.
The PR-SC4 contains a modem and uses
Bluetooth and a Machine to Machine (M2M) SIM
in order to communicate with the Prosa
Infrastructure through the mobile network. The
network is also exploited by the PR-SC4 in order
to compute a triangulation of the position of the
cooling equipment.

The installation of the PR-SC4 has to be performed only and exclusively by qualified and
skilled technicians.
Inside the device there is a GPRS antenna. For this reason, while the PR-SC4 is working it must
be at the minimum distance of 20 cm (8”) from the people. The installation must be done to
ensure this distance.

vided that such alterations can be made without subsequential changes being necessary eady agreed.
If the power supply cable of the PR-SC4 is not double insulated, it has to be physically separated
from the comm cable (the communication cable with the machine.
The PR-SC4 has to be installed in a protected position and not accessible.
This equipment is not suitable for use in locations where children are likely to be present.
