6.3 Signalling by GSM call
When the device is communicating with the alarm system, after the inclusion of the shell,
the alarm will gets the dial tone only, when there is no active call n progress.
In this mode the device has not active communication, only allows calls the alarm system
dialed phone number and after finishing the call it disconnects the connection.
The calls are limitid, as it can ring the same number only once in every 5 minutes.
In case of voice call notification (ringing), the system sends an SMS text message
notification: "
Easy 2 call failed
".
The device stores the last dialed phone number in the
SYSL
parameter.
When the
SYS1
parameter is not configured, then the
Easy 2
will dial the last called number
(which were called by the alarm system) and reads the number from this
SYSL
parameter.
When either the
SYS1
, nor the
SYSL
parameters are not defined, then the device is unable
to signalling!
6.4 Receiving the signalling of events
The device can receive events from two sources: from the alarm system (TIP-RING port or
its input line) or through the input lines. There is an important difference between these,
while the incoming events from alarm system needs immediate response and signalling, ten
the incoming events from the input lines will be handled one-by-one by buffer and will be
waiting for processing which will be performed by the events time sequence.
Independently from the operation mode, the event types can be signalled through GPRS or
GSM voice call.
Furthermore, the input line events are able to generate SMS text message or voice call
notification.
6.5 Life signals
In case of thicker heartbeats/life signals the device will traffic more data through the
network, which is unnecessary in some cases. You can easily exceed the allowed data limit
of the SIM card. It is recommended to configure the default
300sec
or greater
(more rare)
interval for life signal sending frequency.
