DESCRIPTION
Speaker unit module Art.4833 comprising of high quality auto iris lens CCD Day/Night colour camera with infrared illumination LEDs.
LEDS
When illuminated, 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 systems with multiple entrances).
The LED will be o when the system is in stand-by.
If illuminated, indicates that the call from the outdoor station is in progress. The LED will switch OFF when the call is
answered or after the programmed number of rings.
If illuminated, indicates that it is possible to speak because the call has been answered. The LED will switch OFF at
the end of a conversation (or at the end of the conversation time).
If illuminated, indicates that the door lock has been operated. It will switch OFF at the end of the programmed“door
opening” time.
CONTROLS SPEAKER & MICROPHONE VOLUME

When the door open relay operating mode is set to “capacitor discharge”, one terminal of the electric lock must be connected to
ground while the second must be connected to“NO”terminal. The“NO”terminal will supply a temporary voltage when the speaker
unit receives the door open command.
BUILTIN RELAYS  BACK EMF PROTECTION
The Art.4833 includes selectable back EMF protection on the relays. The jumpers marked J4 (One jumper for each relay) are used to
select the protection type. When using a fail secure lock with connections C & NO the jumper should be in the NO position. When using
a fail open lock with connections C & NC the jumper should be in the NC position and when using the codelock to trigger a gate con-
troller or another third party controller the jumper should be removed completely (This disables the protection on the relay).
LOCK RELEASE BACK EMF PROTECTION
A varistor must be tted across the terminals on AC lock release
(Fig.1A)
and a diode must be tted across the terminals on a DC
lock release
(Fig.1B) to suppress back EMF voltages. Connect the components to the lock releases as shown in gures.
