Intelligent Speaker Unit Front Panel Modules

The 4838 Speaker Units are a new introduction to the 4000 series and incorporate
microprocessor technology.
The 4838 Speaker Unit is the building block for the following types of system.
• Audio door entry systems with multiple entrances without the need of the
audio two entrance exchange (Art.502).
• Video door entry systems without the need of the control unit (Art.890) and
on multiple entrances, without the need of the video two entrance exchange
(Art.892).
• With an additional wire, allows for the inclusion of a local door bell (only on
system without privacy of speech) having a different call tone from the external
call.

The 4838 (in each version) has a dip-switch that allows for the adjustment
of the following settings:
- To set one of 4 different call tones.
- To set the number of rings.
- To set the conversation time.
- To set the door opening time.

In addition to conventional acoustic signals, the 4838 speaker unit gives visual
indication relevant to the system operation by the 4 LEDs on the front panel:

• The first LED (red) marked by the symbol , if switched ON, indicates
that it is not possible to make a call because a call or a conversation is in progress
(from the outdoor station from which you are calling or from another
outdoor station on system with multiple entrances).
• The second LED (red) marked by the symbol , if switched ON, indicates
that a call is in progress. The LED will be switched OFF when the call is
answered.
• The third LED (yellow) marked by the symbol , if switched ON, indicates
that it is possible to speak. The LED will be switched OFF at the end of
conversation (or at the end of the conversation time).
• The fourth LED (green) marked by the symbol , if switched ON,
means that the door lock has been operated. It will be switched OFF at the end
of the “door opening” time.
As a result of the above features, the 4838 speaker units provide a cost effective
solution with more features and, at the same time simplify installation.

The 4000 series has been designed using the latest 3D modelling software. The new design is characterised by a number of new features: The modules with front plate and push button are manufactured in mirror finish stainless steel. The frame (which is also the module support) is manufactured from one piece of die-cast aluminium alloy which gives substantial strength to the outdoor station. Modules are attached to the module support frame using a simple but strong clip system. The fixing system of the front panel (flush or surface) uses torx pin machine screws.

The modular system consists of 3 main items:
-The Modules.
-The front supports (for flush mounting).
-The surface mounting units (for surface mounting).

The module support frame (flush or surface) is hinged to the back box. This allows for ease of installation and connection as both hands are free.
The standard finish for module support frames and surface back boxes is embossed, metallized "gunmetal grey" while the module front plates are mirror finished stainless steel. Other finishes are available by special order.
