OPERATION
Call Events
For each event it is possible to program a vocal call, send a SMS message or both. The following
table lists the events managed:

Input 1 .... 4
These inputs manage impulse-operated events (alarms, technological detections, etc.). NO or NC
depending on the jumpers settings (see paragraph IN 1, IN2, IN3, IN4 ALARM INPUTS)
Input 5 .... 8
These are NC only inputs. They manage impulse -operated events (alarms, technological detections,
etc.).
RESET Input
This input is able to reset outgoing telephone calls and SMS but it can also be used to handle events
related to a system's double status, since it manages both the input activation event (contact
opening) and its deactivation (contact closing). This input is also related to two functions that can be
activated through the related dip-switches on the card (DIP 1 = automatic reset, DIP 4 = control of the
status of a system operated by the dialler through output 8).
Checking Supply Voltage
Inside the card of the CT952 GSM dialler there is a circuit designed to control the supply voltage in
the +12V terminals.
Based on this control, you can have the "poor voltage" event if voltage proves lower than 9,5V and
the "good voltage" event when voltage switches back to a normal level (above 9,5V).
This control is also combined to the "power saving mode" function, which allows automatic switch-off
of the module in the event of poor voltage (DIP 5).
