1. OVERVIEW OF AA-10 INTERFACE
The AA-10 doorphone-PBX interface is designed to manage the external doorbell of the vast
majority of door systems (4 or 5 wires) through an analog trunk of the PBX. When a visitor pushes
the doorbell, AA-10 makes a call to the trunk. This will be typically managed by the PBX operator.
Then the operator can speak with the visitor at the doorbell and then open the door with a DTMF
command. AA-10 is equipped with a relay to open the door, plus two auxiliary relays (e.g. to turn
on external lights or to control other devices). Many commands can be given through DTMF, such
as: start voice communication with the external doorbell, electric door or gate opening,
(de)activation of aux relay 1, (de)activation of aux relay 2 etc. The device parameters can be
programmed through the phone as well.
2. MAIN CHARACTERISTICS
The main features of AA-10 are:
•
Connection to most doorbell systems (4 or 5 wires)
•
DIN rail mount, fitted with 1 open-door relay plus 2 auxiliary relays
•
Configurable activation time and number of pulses of the open-door relay
•
Programmable using a standard DTMF phone
•
Non-volatile parameter memory (keeps settings even when not powered)
•
Power and status LEDs
3. GENERAL FUNCTIONS
When the external doorphone button is pushed, the device generates automatically a call to the
PBX. As soon as AA-10 detects the operator answer, it stops the ring current and waits for DTMF
commands. In the meanwhile it beeps every 2 seconds. In the “normal” mode the operator must
dial “1” to activate the communication with the external doorphone. Once the voice connection is
established, the operator can activate the open-door relay dialing “2”.
Hanging up, AA-10 returns idle and ready for a new access request. It is also possible to connect
with the external doorphone dialing the suitable digits (dependent on the PBX configuration). It will
beep every 2 seconds and connect the caller to the doorphone when “1” is dialed. This feature is
useful if there is the need to activate a voice connection without an explicit request from the
outside. For example when the presence of a guest is detected using a camera.
AA-10 releases the call and returns idle if the operator does not answer within 45 seconds. If the
operator answers to a call from AA-10 not during the working hours and does not want to open the
door nor speak with the guest, he can simply hang up after hearing the AA-10 tone. An the external
doorphone, it will look like if nobody were present inside.
Calling AA-10 opens the possibility to use its additional features, in particular to activate the two
auxiliary relays according to their programming. They can be used to open additional doors or
gates, as well as to turn on a lamp when it’s dark.
By combining the AA-10 relays with other appliances, it is possible for example to activate the
heating/cooling system.
It is possible to set AA-10 to work in “autoconnect” mode. In this mode, AA-10 will work in the
same way as described above. The difference is that when the operator answer to the AA-10 call,
the system immediately connect the visitor with him (no “1” digit required, as the “normal” mode).
