INSTRUCTIONS
VA/200 POWER SUPPLIER
The unit comprises a DC power sup-
plier and system control card.
The unit supplies in direct current:
1 - monitor, entry panel and acces-
sories (17.5V DC stabilized);
2 - auxiliary services (12V DC stabili-
zed);
3 - electrical door lock, 12V DC or
AC, 1A.
Operating characteristics
1 - System activation timer.
The installation remains active for 30
secs. following a call at the entry
panel. If the handset is lifted during
this interval, the activation time is
increased by 30 secs. and may be
extended to a maximum of 90 secs.
by adjusting potentiometer TV, figu-
re 1.
If the system is activated by the entry
panel button, located on the internal
unit, the system activation time
(when not interrupted by another
call) may be adjusted between 30
and 90 secs. using potentiometer TV
in figure 1.
2 - System deactivation.
The installation is switched off by the
system timer once the set time has
2
elapsed, or on completion of the
electrical door lock function.
3 - Call note.
The unit is equipped with two diffe-
rential call tone generators.
The first generator (terminal 8) is
activated each time a call is made at
the entry panel which simultaneously
causes the system activation timers
to switch on.
The second generator (terminal 8A
and jumper SW in figure 1 energi-
sed) activates without switching on
the system. This means that the
second generator may be used as a
landing call signal.
When jumper SW is de-energised,
the activation of the second genera-
tor causes the system to switch on,
and permits, if required, the identifi-
cation of two call sources (2 entry
panels).
The outputs of the two call genera-
tors can simultaneously control a
1
maximum of 3 internal units.
4 - Door lock release (12V 1A)
The supply voltage to the electrical
door lock is limited to approximately
1 to 15 secs. (adjusted using the
potentiometer
in figure 1) also
with continuous activation of the
door lock release button on the inter-
nal unit.
If the door lock release is activated
by an auxiliary button (connected to
terminal 23), the electrical door lock
is energised for the duration of acti-
vation of the said button.
5 - Conversation privacy.
The unit powers audio and video
conversation privacy when the moni-
tors and handsets (200 and EXEDRA
200 series) are installed in the same
system. The handsets must be
equipped with SC/200 unit.
The use of C/200 handset, in
systems without conversation pri-
vacy, requires the installation of
EKC/200 capacitor.
6 - Stair light control.
The stair light function may be acti-
2
vated using the monitor (when swit-
ched on) using relay VLS/101.

Technical features
• Supply voltage: 230V 50/60 Hz.
Self-resetting electric safety switch.
• Rated power: 60VA.
• Output voltages:
17.5V DC stabilised (0.9A for con-
tinuous service and 0.6A for inter-
mittent service) for monitor, entry
panel and accessories.
12V DC stabilised (400mA for con-
tinuous service)
12V DC (0.5A for intermittent servi-
ce) for electrical door lock.
• Two differential call note genera-
tors, controlling up to 3 internal
units.
• Installation activation time 30 secs.
If the handset is lifted during this
interval, the activation time is
extended by 30 to a maximum of
90 secs. (adjustable).
• Electrical door lock activation time
with time interval adjustment of 1
to 15 secs. Compatible with both
direct and alternate current-opera-
ted electrical door lock (12V DC,
AC, 1A).
• Stair light actuator output: type
VLS/101.
• Working temperature range: from
0 °C to +35 °C.
• Dimensions: 12 DIN units, low pro-
file module, figure 2.
The unit can be installed without
terminal covers, in boxes fitted
with DIN guide (EN 50022).
See figure 2A for overall dimen-
sions.
Alternatively, it can be wall-moun-
ted using the DIN guide provided,
and applying the terminal cover.
See figure 2B for overall dimen-
sions.
NOTE. The tunit is protected against
overloads and short-cicuits by a self-
resetting thermal switch, inserted on
the primary of the power supply tran-
sformer.
Once the switch trips, operation is
resumed automatically once the tem-
perature of the transformer drops
back below 85 °C.
Make sure the cause of the switch
tripping is eliminated.
