9.5. Alarm input settings
In this page it is possible to program the behavior of the acquisition input of the external contact:
•
Call addr.
: IP address of the phone to contact when the alarm condition occurs.
•
Retry:
number of call attempts (max 999).
•
Separation:
separation, in seconds, between one call attempt and another (max 999).
•
Delay:
is the minimum time, in seconds, before the input status change is evaluated. It can be used, for
example, to mask a door indicator left open after the visitor has entered. Assuming that the maximum time
that the pedestrian entrance must remain open is 30 seconds, only at the end of this time a warning
telephone call would be sent to the staff in charge.
•
Inversion:
normally the contact is open and the alarm occurs when the contact is closed. Activating this flag
it is possible to instruct the device to behave in the opposite way (the contact is normally closed and the
alarm occurs at opening).
•
Stop code:
code to dial on the called telephone to accept and silence the alarm (max 3 digits).
•
Announce:
the activation of the input (of the contact connected to him) causes the broadcast of a pre-
recorded message on the local speaker. See message mask for programming voice messages.
The system can generate a VoIP call to alert, after triggering the alarm input contact (from auxiliary devices or from
a button made available in the vicinity) an appointed operator.
A prerecorded message is played back to the called party. It is possible to invert this logic, so the triggering of the
signaling can occur following the opening of the contact connected to the input.
AD639R continuously monitors the status of the contact and in the event of activation it will begin to call the person
who will manage the situation detected on the programmed telephone number and reproduce the message
associated with the event. It is possible to define an acquisition / acknowledgment code for the alarm signal that the
person called must enter to inform the device of the taking of the alarm signal as notified. If the called number
proves to be busy or does not answer or in any other case where AD639R does not receive the acquisition /
acknowledgment code anyway, at the end of each single call attempt it returns in stand-by and it is ready for a new
alarm notification.
When the AD639R receives the acknowledgment code, the alarm condition signaling stops and no further
notification calls will be made. To be able to be triggered again the notification phase of an activation, the condition
that had triggered the previous notification must return to stand-by. To Only following the occurrence of a new
contact activation condition, the notification cycle with notification calls restarts. In practice: if a connected contact
closes and its activation is detected, AD639R starts making alert calls.
In the event that the person called by the system reply and correctly enters the acknowledgment code, the alert
calls will be terminated. To trigger a new cycle, the contact must reopen and close again.
