Calls to AA-514
Call the system AA-514 from the PBX phones is useful to activate the conversation or issue commands for
example when a visitor is detected near the doorphone, through a video surveillance system of the gate, or if some
vehicle arrived at the entrance driveway or as announcer to serve certain areas of warehouses without using a
more complex system of public address audio diffusion (i.e. using the amplified unit AA-514A).
Calling the extension number connected to the AA-514 system, it will answer after the number of rings specified by
the parameter 136. In conversation the caller has the same commands described above for incoming calls to
trigger the door opening and other controls such as the programming, the change of the operating mode, and
more.
It is possible to set the reply of the system by pressing a button or typing a code to be carried out directly on the
doorphone. This service, governed by the parameters 158 and 159, allows to avoid an undesired conversation in
the absence of the specific intended operator in his working place.
It is also possible to force the direction of the conversation (audio delivered to the doorphone / audio received from
the doorphone) following by the reply of AA-514. These functions, governed by the parameter 158, allows to
generate services of monitoring from/to the doorphone. Please note that in all cases the functions of time-
out/reorder tone/silence disconnection are enabled and also the DTMF commands that the operator can normally
send to AA-514. When the system is set up in this way, it is in fact not possible to establish a bi-directional
conversation.
6.10. Additional features of the built-in camera and the dedicated front lighting
The systems equipped with built-in analog color camera can send pictures of the framed area to a monitor usually
located at the operator that controls the passage. The images integrate the normal telephone call. When the
conversation is established, the camera and its dedicated lighting will activate for the duration of the call.
Is it possible to maintain active the camera in a fixed way, not tying it to the conversation, allowing to continuously
watch videos of the framed area. The same service and in a distinct way can be obtained with the lighting function
dedicated to the camera.
The parameters that set this mode of operation are described in the programming table and are the fields from
number 171 to number 175.
It is also possibile to condition the activation of the camera to the composition of a particolar number by AA-514.
This number can be composed on additional keyboard or it can be associated to a button. It is possible to check
max 10 numbers, stored in parameters 241-250. The parameter 143 set this function ON or OFF.
It is finally possibile to force the activation of the camera entering a special DTMF code stored in parameter 177.
Whene the camera is set on in this way it remains active for the duration of the conversation.
