200 additional access codes Special Function
Starting from the 1.8 firmware version, are added 200 more access codes that allow to activate the integrated
relays. The new additional codes can be inserted only by the expansion numeric keypad AA-539K and follow the
same rules of the 3 base access codes. The codes must be preceded by the star key (*). For each additional code,
it is possible to associate the activation of the relay 1, the relay 2 or both. The codes will activate the associated
relay regardless of the AA-539 day/night mode set. To enable this service, it is necessary to program the proper
parameters (from 3000 to 3199); please refer to the parameter table for the correct values.
6.8.
Calls generated by AA-539
These are the calls that the system generates on the line, triggered by the pressure of the button by a visitor by the
previously described ways.
Who answers the call can speak to the caller for a fixed time set in the parameter 101. If the conversation goes on,
warning tones will be played in the phone so that the operator can enter the code set in the parameter 127 to
extend the call duration.
Also during the conversation, the operator can enter a code to open the door (parameter 120/141). The parameter
119 contains the code to close the call. If it contains the same code of the parameter 120, the door will open and
the doorphone immediately release the line for the next possible visitor. If the parameter 120 contains a different
value than parameter 119, once the door is opened, the talking will remain active until the timeout expires or, if the
operator hangs up, the system returns to standby after a few moments for detection of the reorder tone.
It is also possible to enable the system to hang up and go back to standby if it detects silence that lasts during the
conversation. To enable this feature the parameter 161 must be set to 1 and must be defined in the parameter 162
for how long the silence lasts in the call; when the system “hear” the silence, it behaves as viewing a reorder tone,
hangs up and returns to standby.
6.9.
Calls to AA-539
Call the system AA-539 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.
Calling the extension number connected to the AA-539 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 an interlocutor.
It is also possible to force the direction of the conversation (audio delivered to the doorphone / audio received from
the doorphone) following the reply of AA-539. These functions, governed by the parameter 158, allows to generate
services of advert/monitoring to/from 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-
539. When the system is set up in this way, it is 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-539.
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.
