1. PRESENTATION
AD638 allows to realize Paging Amplification Audio Sound Systems in a standard LAN network completely
integrating with IP-PBX SIP in order to be able to play announcements from any telephone in the internal network
and any technologies: analog, SIP, Smartphones and Softphones.
Access can be authorized by Password with code to be typed before starting the announcement. Two internal
relays can be programmed to be automatically activated when it is called or to be controlled from the phone via
LAN that originated the call to the AD638 speaker, eg. to report the event to any auxiliary devices connected
downstream.
The system programming is done remotely via LAN thanks to the integrated Web server. AD638 incorporates an
efficient Class-D 10W (2x5W) amplifier.
2nd SIP Account – Night Ringer. AD638 can be registered on the PBX with a second telephone number, different
from the one used for ads and inserted in the night ring group. To the arrival of an incoming call, the system plays a
sound (user selectable) to all the network speakers. The volume can be adjusted independently of the others
managed audio channels.
Inputs from external contact with a variety of functions, for example: provide to make a SIP call to a
preprogrammed number and inform the operator of the event with an appropriate voice message. The signaling
can be repeated a number of programmable times, the operator can interrupt the sequence with a keyboard code.
Other examples of use will follow in this manual.
Multicast Audio Streaming for music and announcements diffusion. AD638 handles up to 16 multicast channels
in LAN with priority levels to allow the background music broadcasting on loudspeakers network. The generation of
musical programs in streaming audio can be managed from a PC of the LAN/WAN network with special software or
special TEMA Encoder.
Service "SIP Security Info Call" - Emergency SIP Call. By connecting a button or an external contact, AD638 can
call a phone number programmed to alert the event with a specific warning message. It is a security service for
emergencies or simple request for help and information, and allows a one-way phone call.
Total remote management via LAN, integrated Web Server. Programming, configuration, loading and listening to
audio files, firmware release update, audio volume adjustment, backup and restore the configuration, device
reboot.
Possibility to connect one or more external passive loudspeakers on the 2nd amplifier to expand audio coverage
of the served area. High output power of 40W (2x20W) when powered by an external power supply, automatic
adjustment of power with 10W limitation in case of power supply by LAN cable via PoE only.

5. OPERATION
In stand-by and correctly configured, the system waits for incoming calls.
The device allows also the “streaming” Multicast sound diffusion. In this case the RTP audio diffused in LAN will be
played amplified by AD638. Differing from the announce mode on direct call, with multicast mode, more devices
can diffuse the same message at the same time, useful for general pre-recorded ads or for music sound diffusion.
The operator who want to make an announcement on the device will make a call, from any extension of the PBX, to
the number to which the device is registered or to its IP address in the case of Peer-to-Peer connection.
It is always monitored the change status of an alarm input to which it is possible to associate a number to call and a
message to be played to the called party answer. It is possible to make common adjustment of the level output of
the speakers to better suit the acoustic characteristics of the served area.
The system can activate a relay contact for signaling to external devices.

Application
The application does not require the presence of an IP-PBX
and the presence of the 220V network on site (Within 100
meters from the switch). Each A 638 SIP can be reached by
SIP phones that can launch an announcement. The speaker
power supply travels on the same UTP cable from the PoE
switch. Thanks to the integrated microphone it is possible to
hear the sound of the area of the respective speaker. The 2
integrated relays can be activated by the IP phone that
originated the call to operate additional services.

6. OPERATING MODES
6.1. Calls to devices
Call from the PBX phones, of any technology, to the AD638 system allows to make announcements to the network
speaker. However, it is a normal telephone call, typically unidirectional although AD638 makes possible to hear the
sound present in its vicinity, being equipped with an internal microphone. Calling the extension number connected
to the systems, they will answer after a set time. It is also possible to have an appropriate code to protect the
function from unauthorized access. Hang up to end the announcement. Any background music will be automatically
restored after some seconds.
6.2. RELAY function
The relays are typically used to signal to any auxiliary external devices that the announce is played, automatic
activation call per call. If not used for the function described above it is available and can be controlled with an
appropriate code from the caller's telephone.
6.3. Alarm Input IN1: calls generated for acquisition of external contacts for special signalings
Are the calls that the system generates on the VoIP line, after the activation of the IN1 input, to a number (or IP
address) set for the warning. When the operator answers, a pre-recorded message is sent to him. It is possible to
associate a phone number or an IP address that will be called when the input is activated. It is possible to establish
the activation condition of the same. It is the closure of the external contact that triggers the signaling sequence but
it is also possible to invert this logic, so that the triggering of the signaling can occur following the opening of the
contact connected to the input. AD638 continuously monitors the status of the contact in the event of the condition
of the activation stored on non-volatile memory card. As soon as possible it will begin to call the person who will
manage the situation found at the telephone number programmed reproducing the message associated with the
event. It is also possible to choose to play on a local speaker and on any connected audio output a pre-recorded
message, which will be played prior to the call to alert the present persons in the area served by the system
detected event. It is possible to define an acquisition/silencing code of alarm signaling that the called must type to
inform the device of the alarm acknowledgment. If the called number is busy or does not reply, or in any other case
where AD638 does not receive the capture/acknowledgment code, at the end of each call attempt return in standby
and prepares itself for a new alarm notification
When the systems receive the correct acquisition/acknowledgment code related to the alarm in progress, the alter
signaling will stop and will not be carried out further alarm notification calls. In order to be ready again, it is
necessary that the condition which had triggered the previous notification returns in standby. Only at the
occurrence of a new activation of the contact condition the calls cycle with the alert notification will start again. In
practice: if a connected contact is closed and it is detected its activation, AD638 starts to make warning calls.
In the event that the person called by the system answers and successfully enter the acknowledge code, the alert
calls will be terminated. If the contact that had triggered the alert, however, remained closed (this obviously
depends by the external device that controls the contact) will NOT be triggered another warning cycle! To have new
alerts for this contact, it is necessary that come back in standby before (reopening) and then to its new next
possible closure will be detected from AD638 system with new telephone alerts.

6.4. Streaming Audio Multicast
In a LAN network, the Multicast term indicates the possibility to distribute an information like data, audio or video, to
a group of IP terminals of the Ethernet network. For Multicast are used class D IP addresses and they range from
224.x.x.x to 239.x.x.x. In our case the AD638 system is able to receive audio in Multicast into the specific IP
channel and play it amplified. The audio can be generated from a PC software application (for example VLC) or by
a IP SIP phone. The received audio stream is played without the intervention of any operator, this function is useful
for playing back voice messages and information or emergency announcements (also called "Paging" mode).
Obviously the Multicast audio streaming is unidirectional, the audio stream is sent from source to destination, but
not vice-versa. The audio stream can be sent simultaneously to multiple terminals (same IP Multicast), or only to
distinct terminals (each provided with its own IP 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, another AA-540 and finally from the ADAM Tema software).
Example 1 In a plant, there are two systems, connected to the same network switch. From a suitable phone, it
is possible to make a voice announcement via multicast address 239.255.12.42:
Both systems will play the announcement audio message. Many more devices than those given in the example can
be connected, since there are no limits.
Example 2 In the plant there are two systems with different Multicast addresses.
The phone, selecting to send the multicast voice to one or other address of the terminal, will decide which device
must play the streaming message.
7. COMMANDS AND CODES
During the announcement will be possible to send the commands described here (which will be these by default):
DTMF
Command Function Description
#1 - #2 Activate the relay contact

8. INSTALLATION OF THE DEVICE
8.1. Mounting and positioning of the AD638 system
The IP Speaker must be fixed to a stable surface suitable for supporting its weight, also considering the fact that
hanging to the side or below the fixing surface, the force that the supporting material must oppose is greater than
the nominal weight of the single unit to support.
The AD638 wall mounting bar has holes for wall mounting. The position is adjustable both horizontally and
vertically.
8.2. Accesso to the rear connectors
Once the AD638 speaker is fixed, access to the rear compartment where it is possible to connect the UTP LAN
cable category 5 or 6 and any other service cables. The speaker has incorporated PoE power supply, so it picks up
the power supply directly from the LAN cable if it comes from a PoE switch or an injector interposed in the network.
In the absence of PoE power supply, an external 230Vac power supply is required, available in the Tema catalog
with code AA-39E3 24Vcc-1.5A or the PoE injector code AA-39P4.

8.4. Correct connection of an additional passive speaker
The power amplified SP1 is an output where it is possible to connect an external additional speaker passive paying
attention to its polarity but especially to the load impedance which cannot be lower than 8 Ohm.
Furthermore, it must be respected the maximum output power from the amplifiers using adequate power speakers.
In the simplest case just connect an 8 ohm speaker of at least 20W power or higher. Use cables with different
colors, section of at least 1.5 mm2 and limit the distance from the amplifier to no more than 30m.
Below are some examples of mixed combinations, to serve a wider area but with distributed power.

8.5. 100V audio line for additional speakers away from AD638 IP Speaker
For special applications it is possible to generate from AD638 an audio line at a constant voltage of 100V of max
20W power using a Tema AD320/30 transformer to connect on the SP1 power output. In this way it is possible to
install several other additional speakers (with internal transformer suitable for 100V line and selectable power) even
at distances up to 200 meters from AD638. The total sum of the power the installed speakers must not exceed the
maximum power of 20W.

9. PROGRAMMING
9.1. Preparation for the system parameters programming
Programming is done via the WEB interface. To gain access, simply connect an Ethernet cable from a PC or from a
switch to the LAN port of AD638.
The default IP address of AD638 is "192.168.0.10".
Remember that in order to successfully connect to the web interface of AD638, it is necessary that, in the IP
addresses configuration of your PC, is present the subnet 192.168.0.x, where "x" is any number between 1 and
254 and different from 10. See below how to configure your PC to reach the correct subnet. The shown procedure
applies to Windows® operating systems.
Open the Windows Control Panel and set the field "View by": "Category" "Large Icons" or "Small Icons".
Choose "Network and Sharing Center" as shown in the first figure, detect your LAN connection, choosing the one
referring to the network card that you are using to connect with AD638.

Once the correct connection is identified, click on it and it will appear the window where it is necessary to click on
the "Properties" button. It will then open the window where must be selected "Internet Protocol Version 4
(TCP/IPv4)" and then click the Properties button again. See the following figures:
If the PC is already on subnet 192.168.0.x with a mask 255.255.255.0, ignore the following steps. Otherwise,
proceed as follows. (The address of the PC configuration should not be 192.168.0.10). Remember the current
TCP/IP configuration of your computer for any subsequent restore of the correct parameters. Click "Use the
following IP address" and type in the appropriate field the following IP address: 192.168.0.11 (instead of "11" used
in the example it is possible to enter any number between 1 and 254, but excluding the 10 which is the default
address of the system to be programmed). In the "Subnet Mask" enter the netmask 255.255.255.0. Click OK to
confirm the changes. The PC is now ready to configure the door phone. Remember at the end of programming to
restore the network configuration of the PC to its original state if necessary.
Once the IP address of your PC is successfully configured, it is possible to reach the Web interface to configure
AD638 at the address 192.168.0.10 .

MAS-AD638-REV00EN Page 20 of 52
9.2. Access to programming
To program the device, it is sufficient to use a standard browser such as Explorer, Firefox, Chrome or others. The
default address of the device is 192.168.0.10 with a mask of 255.255.255.0, and the user/password with which to
connect are master/master. Make sure to have access to this network segment from your computer. Once logged
in, it is possbile to change the administrative password for the maximum safety of your device. Once logged in, it is
possbile to change the administrative password for the maximum safety of your device.
The use is very simple and intuitive, it is always visible on the left the menu for selecting the functions to be
programmed, while on the right is shown the configuration window that is currently active. Any change will be
confirmed by pressing the "Apply" or "Save" buttons. Closing the browser or changing the page without selecting
those buttons will make lost any change .
Any changes do not require restarting the device (except the change of IP address, and the software update).
As specified above, for each change on any page, it is NEEDED at the end to immediately press the
"Apply" or "Save" button otherwise the changes will be lost. It is also advisable, before making
changes in the fields, to always refresh the Web page with the F5 browser function key or the
corresponding icon.
