9.2 BATTERY TEST
Removing the jumper JP1
(fig.11), battery voltage test is
enabled.
In case of power failure (18V AC
missing), the barrier is powered
by battery. If power failure
persists, in order to save the
battery from complete run-down,
it is automatically disconnected
as soon as voltage drops below
9V.The battery is automatically
reconnected as soon as mains
power returns.
V ATTENTION W
EXPLORER II barriers can be powered by 18V AC or 13.8V DC.
POWER SUPPLY 18V AC
If alternated current is used,
it is necessary to connect a
12V 2.1Ah battery inside
every device (fig. 12).
POWER SUPPLY 13.8V
DC
If direct current is used only
one battery must be
connected inside the power
supply casing (fig. 13). Do
not fit batteries inside the
barriers, e.g. for 4 couples
of barriers it is necessary
to use a 13.8V DC/3A power
supply with min. 12V 17Ah
battery.
In this case, it is not
possible to profit from the
battery test function, the
jumper J1 has to be
inserted.

Outdoor Microwave Barrier - EXPLORER II
In case of a triangular installation
using three barriers only (fig. 2), the
following precautions have to be taken
since in one angle a receiver has to
be installed next to a transmitter:
+ RX1 has to be placed at 10m
distance from the point of
intersection formed by the
radius of transmission of TX3
and TX1.
+ TX3 has to be positioned at 6m
distance from the point of
intersection.
+ The angle formed by RX1 and
TX3 should not exceed 60°.
2.3 ANGLE POSITION
To ensure total coverage with two
beams crossing, it is essential to
respect the distances between the
axis of the tubes (fig. 3) as indicated
below:
+ type 0600:
distance A1 = A = 3m
+ type 1200:
distance A1 = A = 4m
+ type 1800:
distance A1 = A = 5m
2.4 MOUNTING HEIGHT
In order to obtain best performance
of TX and RX, it is important to
respect the indicated perimeters
(fig. 4) as shown below:
+ type 0600: H = 65cm
+ type 1200: H = 90cm
+ type 1800: H = 115cm
