FAQ Frequently Asked Questions
How is AA-15 powered?
AA-15 can be powered directly from the UTP LAN cable through a PoE switch, if not, it can be powered at 230Vac
with a PoE injector or an external power supply, both in the Tema catalog.
Does AA-15 work with an Asterisk VoIP PBX?
Yes. AA-15 has also been tested with all the PBXs of the most prestigious brands such as: SIEMENS - AVAYA -
ALCATEL – PANASONIC – SAMSUNG - NEC - 3CX - LG - WILDIX - AASTRA - ASCOM - NITSUKO - SELTA –
PHILIPS - MITEL E SISTEMI BASATI SU ASTERISK
How it can be installed and put into service?
Few steps:
1) Connect AA-15 in a LAN socket to a PoE switch with standard cat. 5/6 cable, or to a generic switch by powering
it with the external power supply.
2) Connect with a browser and assign an IP address and LAN credentials.
3) Register the number assigned to AA-15 in the IP-PBX switchboard in the space reserved for your SIP account
or, in the absence of the IP-PBX, arrange for the doorphone call to be sent to a SIP phone in P2P mode (Peer-to-
Peer).
4) Connect the UTP cable coming from the "TAP" socket of AA-15 to the points indicated in the connection
diagrams provided for the various traditional intercoms on the market in a "parallel" way on the necessary signals.
When a visitor presses the button, AA-15IP generates a SIP call to an internal number, communicating the visitor
with the answering operator, who has the possibility of operating the relay for opening with a code from the
telephone of the gate. In any case, the internal intercom station remains operational since AA-15IP is transparent
and works in parallel.
I can't get to the place where I have to install AA-15 with a UTP cable, can I use a Wi-Fi link?
Yes, AA-15 is a normal LAN network terminal, in this case you need a client access point with the RJ45 LAN output
towards AA-15 and a power supply (for example the plug model T7012L or for DIN rail AA-39D1A) connected to a
230Vac mains socket in the immediate proximity.
Can I connect AA-15 on a 2-wire BUS intercom system?
NO, AA-15 currently only works on traditional 4-5 wire intercom systems. If this need exists, contact TEMA by
supplying the brand and model of the intercom with 2-wire BUS operation to check whether any operating
compatibility has been released on the date.
I have to install AA-15 on a 4-5 wire intercom system but can't find the diagram in the manual?
The compatibility of AA-15 with the various intercoms on the market is constantly evolving, contact TEMA providing
the brand and model of the intercom to be adapted.
I installed AA-15 and everything works correctly, however there are some disturbances during
communication
The quality of the audio received and transmitted by AA-15 is strictly dependent on the quality of the intercom
system, the device does
NOT correct
any disturbances or low audio quality of the existing intercom system but
transfers the audio exactly as it receives it. As they are old intercom systems, it is possible that the quality of
speech is already compromised,
therefore communication must be considered acceptable
, even with some
disturbance, provided that it is intelligible even at a minimum level of understanding. After all, long conversations
are not normally made at the intercom unit.
