Normally it is possible to reach AA-15 from any extension of the PBX to issue DTMF commands, simply by dialing
the number of the internal extension to which AA-15 is connected.
7.10. Acquisition of input alarm contacts
The following screenshot shows the configuration parameters of the alarm event following the closure of an
external contact.
•
Call..
: number or IP address of the phone to contact when the alarm condition is triggered. The input could
be also used as “door opener”: enter the number of the relay preceded by #. For exampe #1 activate the
relay 1, #2 activate the relay 2. The activation time is the one entered in the activation time filed.
•
Attempts:
number of call attempts (max 999)
•
Separation:
separation, in seconds, between a call attempt and the other (max 999).
•
Delay:
it is the minimum time, in seconds, before validating the input. It could be useful, for example, to
mask an open door switch. Supposing the maximum time of a pedestrian gate is 30 seconds, at the end of
this time (if the switch would be still active) an alarm will be send to the reception.
•
Inversion:
the contact is normally open and the alarm occurs at the closing of the same. Enabling 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 the opening).
•
Stop code:
code to dial on the phone calling to accept and acknowledge the alarm (max 3 digits).
•
Announce:
when activating this input, a prerecorded message will be played on the speaker. See
messages management.
The input is associated with a message to be reproduced during the call. A neutral message (“Alarm1”) is
reproduced as standard but the text can be customized. It is possible to associate a phone number or an IP
address that will be called during the alarm phase.
The closure of an external contact triggers the signaling sequence but it is also possible to reverse this logic, so the
signaling can occur following the opening of the contact connected to the input. AA-15 continuously monitors the
contact status and if the activation condition occurs, will call the person at the programmed telephone number and
reproduces the message associated with the relative input.
It is possible to define an alarm acquisition / acknowledgment code that the called party must key in to inform AA-
15 of the alarm taking charge. If the called number is busy or does not answer or in any other case in which AA-15
does not receive the acquisition code, the system returns to rest.
The number of times the alarms are notified and the time between one notification attempt and the next are
programmable, while the time for which the warning message is reproduced is the "Attempts" time set in the
general parameters. At the end of the notification attempts, the alarm condition signal ceases, 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 rest. Only after the occurrence of a new contact activation condition will the notification
cycle with notification calls restart.
However, if the contact that triggered the signal has remained closed, another warning cycle will NOT be triggered!
To get again notices related to this contact it is necessary that it returns first to rest (re-opening) and then on its
new closure AA-15 will be activated again.
