If the system uses the AA-516K expansion, the opening codes must be typed directly on the keyboard preceded by
the star key (*) to distinguish them from a normal telephone call. The visitor will get access without operator
intervention (for example, useful to service personnel or external assistance, which for work reasons comes out
and returns back frequently in the company).
It is possible to set in the parameter 151 the maximum number of attempts of code introduction to open the door in
a way that, when the maximum number set is exceeded, the system make an alert call to the number set in the
parameter 152. This is an useful service to alert people inside the company of an unauthorized attempt to access
or to report difficulty to access by a visitor. The alert is made with a series of calls according to the value set in the
parameter 151.

200 additional access codes Special Function
Starting from the 2.8 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-516K 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-514 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-514
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 be opened
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 detecting 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.
