legend for visitors with numbers to reach without the first digit. For example, to call the operator at the extension
number 311 it must be programmed the prefix with a value of 3 and indicate to the caller to dial the number 11.
In the case there is the need that the the visitor must dial external numbers, this parameter may be useful if filled
with the value of a code that instructs the PBX to use a specific trunk group for outgoing governed by the desired
class of service, with restrictions on certain numbers for calls when the PBX allows it (long distance calls, foreign
calls, fee-based services, mobile network, etc.).
In other cases, remember to activate some kind of control on the possible numbers that a general visitor can dial to
prevent unauthorized calls.
AA-550 is equipped with a special table of up to 60 characters that allows to create a filter on the selections made
by the user, in order to allow or reject it, even without the control of the PBX. This table and this service are very
useful for systems equipped with the full keyboard expansion module.
6.3. RELAYS control with access codes
The opening function of the door opener connected to the two relays can be made available to a visitor who is
familiar with the various preset access codes.
The code is made up by the alternating pressure of the buttons of the device: for example, the code "121212" on
the system AA-550 correspond to press the first and the second button in sequence three times. It is possible to set
up to three access codes for each relay, one for the Day mode, one for Night mode and one for the Interval mode
(see par. 9.7). Upon the detection of the correctly inserted code, the corresponding relay will be activated for the
time set in the parameter.
The opening codes for the system based on 4 buttons will obviously consist of combinations of single digits from 1
to 4. If the system is equipped with the AA-516P expansion with 8 additional buttons it is actually possible to use all
the digits excepts zero (1-9).
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).
Relays can be also actuated with any of input signals (for example it is possible to connect an internally installed
push button for exit), see in the “Alarms – Inputs setting” programming mask the “Call” field.
6.4. Calls generated from AA-550
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 general parameters (see. par. 9.5). If the
conversation goes on, warning tones will be played in the phone so that the operator can enter the code “#5” to
extend the call duration.
Also during the conversation, the operator can enter a code to open the door (see. par. 9.5). Once the door was
opened, the conversation may be closed or not, according to the programming of the relay. If it is configured so that
the call is not closed, it will remain active until the timeout expires or, if the operator hangs up, the system will return
immediately in standby mode.
