The communication products in the Zelio Logic range are primarily designed for
monitoring or remote control of machines or installations which operate without
personnel.
Examples:
monitoring of lift pumps, livestock buildings (ventilation, feed level, etc.),
refrigeration units, car-washes,
alarm in the event of failure of industrial or domestic heating boilers,
remote control of lighting: car parks, warehouses,
remote control and monitoring of escalators in large stores, in the transport sector,
refuse compactor full alert.
The communication range comprises:
a communication interface connected between a smart relay and a Modem,
GSM
(1)
or analogue (PSTN)
(2)
modems,
“Zelio Logic Alarm” software.
The system comprises:
a
Remote station
, machine or installation to be monitored

a monitoring or control
Receiving device which may be one of the following:
a PC

fitted with an analogue PSTN Modem

or a GSM modem,
or a GSM telephone

.
Note:
the majority of Modems built into PCs can be used.
Various combinations are possible between the types of Modem used on the
Remote
station
and the type of
Receiving device
(PC + Modems or GSM telephone).
The type of architecture selected will therefore depend mainly on:
whether or not an analogue telephone line is available,
whether or not it is necessary to send SMS messages,
