DESCRIPTION
Art. 4838 series speaker units are intelligent devices with a built-in
microprocessor to control the operations. This speaker unit offers
easy of installation (on audio door entry systems with multiple en-
trances there are no audio entrance Art. 502N switchers required)
and assists the user by providing a number of visual and acoustic
signals during normal system operation (call, conversation etc).
The speaker unit circuitry includes:
• The microprocessor;
• The transmitting amplifier with condenser microphone and
volume control;
• The receiving amplifier and volume control;
• 2 LEDs to illuminate the name plate (except Art. 4838-0).
• 4 LEDs for operation visual signalling;
• The lock release relay to enable the electric lock;
• The modulated tone generator;
• Two programming dip-switches one 3 way and one 8 way.
This speaker unit together with a camera module Art. 4830, can
be used on video door entry systems. On systems with two or
more entrances, there is no video entrance exchangers Art. 892
required. Standard Art. 506N relays can be used instead.
LEDS
The first LED (red), if switched ON, indicates that it is
not possible to make a call because a call or a conver-
sation 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), 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), 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), if switched ON, means that the
door lock has been operated. It will be switched OFF at
the end of the "door opening" time.
