1. INTRODUCTION
The AA-550 is a Doorphone that can be connected to any VoIP SIP PBX, as a SIP extension, with the possibility of
power either through dedicated external power adapter, or through PoE on the LAN. Alternatively it is possible to
be used in a Peer-to-Peer connection and allows the opening of one or two electric locks (two integrated relays).
The AA-550 series differs from AA-540 family in a more flexible housing for flush or wall applications and is
available with or without color camera with lighting Led. AA-550 is installed for example on a gate for external
control and when a visitor presses one of the buttons to show up, make a VoIP phone call to the number of the
operator, allowing audio communication.
In addition, thanks to the integrated color camera (version AA-550C), it is possible to see the visitor directly to the
operator's internal IP video phone or on the screen of his PC with a standard internet browser, ensuring the
maximum security of the framed area. Having the possibility to monitor the area with the integrated camera, AA-
550 can be called directly from an extension phone to communicate with any visitor and/or to control the opening of
the controlled gates, without any visitor request for access. Once it is established that the visitor must enter into the
company, the operator may open directly from his phone, with a DTMF tones code, the electric gate or pedestrian
gate.
AA-550 can be programmed with a web interface reachable from any PC connected to the corporate LAN, using a
common web browser by typing the IP address of the device.

5. OPERATION
When the call button in idle mode is pressed, AA-550 automatically generates a telephone call through the VoIP
PBX. The visitor begins to listen to the speaker of AA-550 the outcome of his request for access, or listen to the
ringing tone and the subsequent reply by the operator that was called.
Optionally, before forwarding the call, it is possible to set a message playing (matched to each key and each
mode), such as "The company is closed, wait for the reply from the operator...".
The operator who asnwers to the visitor can immediately decide to activate the electric lock directly typing the
correct sequence of programmed DTMF digits codes (opening the door), and hang up when finished. When the
user hangs up, AA-550 will return to the idle state recognizing the closing and will be ready for a new access
request.
It is also possible for the operator or other extensions to call the phone number where AA-550 is connected to
reach the Doorphone, to speak with people close to the entrance and to activate the electric lock without waiting for
a visitor call. It is also possible to protect this feature with a connection/listening code.
It is possible to adjust the audio level of AA-550 in order to better adapt to the acoustic characteristics of the area
where it is installed.
With the AA-550C version, which has an integrated color camera, it is possible to see the framed area. The video
of the camera is carried on an IP Stream directly on the corporate LAN using the same LAN cable for connecting
AA-550C. It is possible to see the framed area on an IP phone with video capability or directly to a PC via a
standard browser.
5.1. Buttons and numeric keypad expansions
Adding the AA-506P expansion, it is possible to have 8 extra buttons, to get up to 12 call buttons in total. Adding
instead the AA-506K expansion it is possible to have the telephone keypad that allows some additional services.
There is for example the possibility for the visitor to directly call a phone number, or to call the numbers
(appropriately pre-programmed in the parameters) of the Speed Dial operating mode.
See for example the case of a possible visitor who goes to the entrance of a building site and among the dozens of
companies on the job site must conctat one in particular: just provide a legend in the proximity of the device that
has the instructions and the various numbers to call to get in touch with the person of each company.

TEMA TELECOMUNICAZIONI SRL Doorphone AA-550
MAS-AA550-REV07EN Page 13 of 67
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.

5.3. Device diagram
The AA-550 Doorphone is connected to the PBX via the LAN RJ-45 port. The contacts of relays will be used to
drive an electric door opener and/or a light at the entrance, a gate for pedestrian and/or the driveway gate.
The figure below shows an example of Doorphone connection:
Description of the new features made available by installing AA-550 in the company:
• The visitor that press one of the Doorphone buttons will be put in contact with the operator who may decide
to open the electric lock from his telephone and give way to access the company. In the same way he may
decide to open the driveway gate to give access to a vehicle.
• The operator who has been able to monitor the video in the area, can directly operate the two possible
access gates, without waiting for the visitor to press the buttons on the Doorphone.
• During the Night mode, when the operator is no longer present in the company, the call generated by the
Doorphone can be forwarded to a telephone number of a guardian that could open the gates and let the
visitor to access by acting the relays even remotely (eg. being reached with a call to his mobile phone).
• The two integrated relays could be used, in another case, one for the gate and the second to activate a
lighting system of the entrance area, to be activated only when there is a transit of persons or vehicles.

6. OPERATING MODES
The system has the label holders combined with the buttons. When a visitor presses one of the buttons, the system
make a call on a PBX extension associated with the pressed button.
The numbers that are called may differ depending on the operating mode in which the system is programmed, Day
- Night mode / Interval mode, (see par. 9.6).
If the system AA-550 is equipped with the 8 buttons expansion the operation described below for the 4 buttons on
the base system remains valid and is extended to additional buttons.
In the case of keyboard expansion, are valid the same informations as stated for the buttons on the base system
while the keyboard allows to dial the desired number, or to handle additional functions described later.
If is used the keyboard in Speed Dial mode, described below, the descriptions of the operating modes listed below
are valid only for the numbers associated with the Speed Dial service.
6.1. DAY / NIGHT / INTERVAL modes
In each of the three possible operating modes, the system makes a call to a number after pressing a button (or call
to two numbers if also the second number is programmed) for a configurable number of times. It is also possible to
specify an additional final number, called the "supervisor", to contact at the end of the previous programmed
attempts. The call is considered successful when the operator answers.
The visitor hears the signalings of the current call preceded by a greeting voice message, when enabled.
If the visitor presses a button again while the call is in progress, the system stops the call and returns to standby.
For the systems with the keyboard expansion you must press the star key (*) to stop the call.
The system can be manually placed in a Day, Night or Interval (the operator will send a special command to the
system), or it can automatically switch to each mode according to a time schedule.
The active mode is stored also when the system is powered off and then reactivated when it will be powered on.
6.2. Additional features of the keypad expansion
If the expansion module AA-516K is installed, the visitor can make a call simply by dialing the desired number if
known by him or presented into an index table placed near the Doorphone (eg the AA-516R expansion), typing it
directly on the keyboard.
The introduced number to dial is considered finished after about two seconds after the last dialed digit by the
visitor. It is possible to speed up the dialing without waiting for the system timeout by pressing the pound key (#) at
the end of the number, in which case the call is made immediately.
The visitor, realizing that has made mistakes in typing can be immediately cancel the entered digits by pressing the
star key (*), the same key has the function to break down if the call is already in progress.
In addition to direct dialing mode, the keypad allows for Speed Dial function, in which it is possible to associate a
number to call to each digit of the keyboard (10 phone numbers associated with the digits from 0 to 9, see par. 9.9),
with the possibility to differentiate between Day, Night and Interval.
According to the system mode, the visitor can then contact one of the 30 numbers entered. The Speed Dial mode
is NOT exclusive but coexist with the possibility of direct dialing with the only exception that it is not possible to
directly dial single digit numbers. Having to select the visitor directly to a single-digit numbers it is not possible to
use the Speed Dial service.
The Speed Dial feature (single digit of the keyboard) behaves as pressing a button on the base system and it is
also adjusted according to the parameter 118 about the operation in Day/Night mode, Day/Night with repeating
calls, or Group mode. In practice, for the user, the keyboard also adds 10 more call buttons.
By directly dialing the number to call on the keyboard, may be possible for the visitor to dial a number that you do
not want to be dialed, or at least reached (eg outside the company). To avoid this possibility it is possible to use a
prefix before the number to be dialed. If the numbers of operators are in the numbering plan of the PBX (internal
extensions), it is sufficient to program the parameter with the first digit of the numbering plan and expose the

TEMA TELECOMUNICAZIONI SRL Doorphone AA-550
MAS-AA550-REV07EN Page 16 of 67
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.

6.5. Calls to AA-550
Call the system AA-550 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-550 system, it will answer after a preset time. In conversation
the caller has the same commands described above for incoming calls to trigger the door opening and other
controls such as the change of the operating mode, and more.
It is possible to set the reply of the system by pressing a button of the Doorphone. This service, governed by
general parameters (see. par. 9.5), allows to avoid an undesired conversation in the absence of an interlocutor.
It is also possible to connect the audio of incoming calls only after the user enter an access code, for example if the
device is installed in protected environments.
6.6. Acquisition of external contacts for special applications
AA-550 has the ability to monitor and acquire the status of external 3 contacts to make reports, indipendent from
the normal operation as Doorphone. In the following descriptions of the services associated with the acquisition of
these external contacts, will be used the generic "alarms" word.
For each available input, it is possbile to associate a phone number or an IP address that will be called when the
input is triggered. AA-550 has a maximum of three separate inputs of the acquisition, and then up to three different
numbers. The programming of the inputs is described in par. 9.7. It is possible, for each input, to set the condition
of activation of the same
Normally, the closing of an external contact connected to the corresponding input will start the sequence of
signaling but it is also possible to reverse this logic, so the signaling can be done following the opening of the
contact connected to the input.
AA-550 continuously monitors the status of three contacts and the alarm condition is stored in a non-volatile
memory. As soon as possible it begins to call the person who will have to manage the alarm situation and plays the
message associated with the relative input (see par. 9.10). It is also possible to play a prerecorded message,
reproduced before making the call.
For each input, it is possible to define a code acquisition / acknowledgment of the alarm that the called must type to
inform AA-550 that the alarm has been notified.
If the called number is busy or does not answer, or in any other case in which AA-550 still does not receive the
code acquisition / acknowledgment, at the end of each call attempt AA-550 back to standby and prepares itself for
a new alarm notification.
The number of times that the alarms are notified and the time between one notification attempt and the next one
are programmable for each contact, and the time for which the warning message is played is common to all and is
the time "duration attempt" set in the general parameters (par. 9.5).
At the end of the notification attempts or if during notification AA-550 receives the correct code acquisition /
acknowledgment for the alarm in progress, the signaling of the alarm condition will stop and further notification calls
(for each input) will not be issued.
In order to re-trigger a new notification, it is necessary that the previous alarm condition back to standby. A new
alarm condition of the contact will start the cycle of alert notification again.
In practice: if a contact connected to one of its inputs is closed and it is detected its activation, AA-550 begins to
make calls warning. If the person called by the system reply correctly and insert the silence code, then the
waarning calls will be terminated.
If the contact that had triggered the alert has however remained closed (this obviously depends from the device
that controls the external contact), will NOT be triggered another round of warning! To obtain alerts for this contact
it is necessary for it to come back in standby before reopening and then with a new possible subsequent closure
will be re-detected by the AA-550 system with restoration of telephone notification.

6.7. Multicast audio streaming
In a LAN network, the term Multicast indicates the possibility of distributing information to a group of terminals. For
Multicast, class D addresses are used and range is from 224.xxx to 239.xxx
In our case, AA-550 is able to receive Multicast audio and play it on its speaker (see par. 9.10). Audio can be
generated by a PC software application (eg VLC), an IP phone or another AA-550 Doorphone. Infact it is possible
to program each AA-550 button to immediately dispatch the audio captured by the microphone (see par. 9.9).
The received audio stream is played without requiring the intervention of any operator, this feature is useful for
playing back announcement voice messages (also called PA "paging").
Obviously the streaming is one-way, meaning that the audio stream is sent from the source (such as a phone) to
the destination (the Doorphone) but not vice-versa.
The audio stream can be sent to multiple terminals simultaneously (terminals that have the same Multicast
address) or to separate terminals (each with its own address).
It is possible to program up to 16 audio receive addresses, each with its own priority and its playback volume, so
that the same terminal, if it is already playing audio (eg music) can be interrupted by a higher priority stream (for
example an announcement) and with a different volume (typically an announcement must be played at a higher
volume than background music).
The audio supported by this mode is in the G.711 format (aLaw or μLaw), G722 or linear high quality 16 bit
(proprietary format, diffused through the AD615 device or another AA-540).
Example 1
In the installation there are 2 Doorphones, connected to the same network switch. From a telephone, I make a
voice announcement to the address 239.255.12.42:
Both Doorphones will reproduce the audio message announcement. It is possible to connecte more than the 2
devices as indicated in the example, since the only limit is the bandwidth of the network.
Example 2
In the installation there are 3 Doorphones. It is possible to use each system to play an announcement,
programming one of the four buttons to perform this function (for example the button 4):
Holding down the button 4 on Doorphone number 3, the audio captured by its microphone is sent simultaneously to
the Doorphones 1 and 2. Please note that it is possible to program each system so that it can send the audio
streaming to all the others and it is also possible to use all four keys only for the Multicast service.
