The same operation mode may be applicable in public facilities, large buildings and other environments. The calls
(if allowed by the appropriate class of service of the extension number assigned to AA-550 on the PBX) can also
be made to mobile phones or trunks and not only just to the extensions of PBX to which it is connected.
It is also possible to dial only the final part of the number using the operation mode with a root number. In this case
the system prepends to the dialed number on the keypad a pre-programmed prefix. For example, if the root
number is "3" and the user types on the keyboard "14", the system will associate the prefix and dial the number
"314". This service is also found useful to mask the true extension number of the person to contact.
In addition, this field or service may be used to avoid to make calls directly from the system, when equipped with a
AA-516K keypad, engaging the external lines of the connected PBX. In fact, if a visitor will try to make dial
02123456, the system will call 302-123456 preventing the external call.
The direct dialing mode is NOT an alternative to the speed dialing mode and can both work.
Below is shown the position of the buttons with their logic mapping on the systems.
5.2. Possibility of opening electric locks by entering a passcode
It is also possible to allow the access to some employees making them aware of a code (this feature can be
enabled or disabled) so that they can have access without the operator intervention, simply by typing the code in
the right sequence on the keys of the Doorphone.
For example set the code "221441", who knows it will have to press the buttons in the right sequence
2+2+1+4+4+1 of the Doorphone buttons for the opening of the electric lock. This particular feature can be useful in
case of installation of Doorphone, for example, in a doctor's office, a hallway or in all those cases where the public
(not authorized) must call the operator while internal employees can instead have access by using this kind of
authorization.
Please note that if the system features the expansion keyboard, the access code must be entered by preceding the
star digit (*). The star digit must be dialed to tell the system that is entered an access code rather than dialing a
number.
It is possible to define codes that only work in Day mode or other only for Night or Interval mode.
