8. INSTALLATION
8.1. Installation of systems
The units are presented with the exterior part elegant and compact, the only part that will be visible and with the
wall plastic box to be recessed into the wall. It is possible to power AA-550 via the Ethernet connection if PoE
(Power Over Ethernet) is available. In this case it is possible to avoid the use of an external power supply but you
have to keep in mind that the power delivered from the PoE may not be sufficient for the proper functioning of the
internal relays and the simultaneous supply of external electric locks. To overcome this, just use a external power
source that will provide the current necessary for the proper operation of the electric connected to the relay
contacts. The front part with the electronics of the system is separable from the bottom plastic wall box. This allows
a greater convenience during the preparation stages of the cables and the wall finish that will host the Doorphone.
The front panel with the circuit board (to preserve during the installation stages) could be separated from the plastic
bottom and it can then be left out in an appropriate place and put into operation at the end of the preparation of the
wall and cables. The following describes how to provide for the installation of the parts, while later in the manual
will be described how to connect the cables and more in the appendix there are the drawings, and the measures
for the various hardware elements.
The systems are shipped from the factory without the inserts screwcover
plugged so that the screws are readily accessible. Removing the two
front screws with the special wrench provided in the kit, the frame will be
free to rotate on the left side of the plastic wall box.
It is possible to pull out the aluminum frame hat holds the front and the
electronic card from the flush box in order to work only with the plastic
box for placement operations and its flush mounting to walls. The
aluminum frame with the card is the only part of the system that will
remain visible on the wall.
To help in "finishing" the wall, with particular reference to the edges
between the back box and the wall itself , there is the possibility to insert
between frame and box (then flush with the wall) a special accessory
called AA-517. This one improves the aesthetics of the system in the
case the wall is made of a material that can not be cut or not match to
the flush plastic box
Moreover, this flat frame, applied between the wall and the aluminum
frame of the system once screwed, provides to help to seal the front/wall
junction. Keep in mind to prepare the wall with the arrival of the cables
coming out from their tubes run at the holes easily obtainable on the
plastic box (use the precut holes from where you want to route the
cables).
Do not use corrugated tubes or other with too small diameter to prevent to obstruct the passage of the
interconnecting of the system expansions (AA-516P/K in the various models). Consider it at least in the installation
of the tubes between the main system and the additional system AA-516.Once the plastic base is placed and
finished the masonry and recessing work, it is possible to proceed to connect the signal cables to the system. The
wires contained into the walled plastic box will connect then to the screw terminals on the card attached to the front
of the system. For details on connections, model by model, please refer to the following pages.
For the closing of the system after the cable connection, support the front aluminum frame aligning the two
transparent plastic plugs on their insertion holes on the left side of the flush plastic box, gently push it until it stops,
turn then around the front to close the box and secure with the two special screws planned for this purpose. Ensure
that the panel rests firmly on the wall or on its AA-517 aluminum frame (if present) and check that the cables are
properly seated and not get caught between the front panel and the rear box. At the end cover the screws with the
special plastic inserts supplied with making just slip into their seats.
