8.4. Alarms
8.4.1.
Dialer for alarm contacts
The system allows you to connect two input alarm contacts, and check their status. At each end of
the contact you can send an SMS to one or two preset numbers.
You can program the duration of the closure of the contact to be collected (Activation debounce)
and its time to rearm (Reactivation debounce), time for which successive closures of the contact
after the first acquisition will be ignored. It is possible to assign a text message to be sent, one for
each contact.
•
Activate this alarm:
empowering the vision of the contact entry to generate alarms output
•
Activation debounce (mS):
activation of the contact input is considered valid when it is stable
for the time set in this field (in milliseconds)
•
Reactivation debounce (S):
when the contact is achieved, a subsequent acquisition will take
place only after this time, in seconds, to avoid multiple messages for the same event
•
Use module number (1-2):
Indicates which module will be used to send the message
•
Number (1) for SMS sending:
number of GSM phone to send the alarm SMS
•
Number (2) for SMS sending:
second (optional) number of GSM phone to send the alarm SMS
•
Message text:
this is the real text message to be sent
8.5. Prepaid settings
The "Prepaid" mode does not refer to credit loaded on each SIM card, but the possible credit in
minutes (free or low cost calls) made available by the operator for outgoing calls (according to the
choosen contract). DIAL-112, in this case, take account of minutes of use for each SIM card
(regardless of the number called) to see if the total time of call exceeds your set. In this case you
can decide whether to lock the device, continue to make calls (it is still shown the time of use of
SIM), or send an SMS alert. Blocking of the device is done at physical layer (Layer 1 ISDN) so that
the PBX can no longer commit the attack linked to it (the call is then routed from the PBX to the
local line or to other GSM gateway). In the case of a possible incoming call, the ISDN line is
temporarily reactivated, but in this condition a possible call-generated output would be permitted.
