1. FEATURES
Each individual beam is formed by two parallel beams 4 cm distant, this system allows to
eliminate all the false alarms caused by insects (flies, butterflies etc...) That can be laid at the
TX or RX LED, so to get the alarm condition is necessary to obscure both the rays that
compose the beam.
The barrier is composed by a transmission unit (TX), which emits synchronized modulated
infrared beams, and by a receiving unit (RX), which receives all beams emitted tuned with
synchronized signals.
In event of interruption of one or more beams, depending on AND setting or time delay set on
DIPSWITCH, receiver column will furnish alarm status by a LED indicator and relay opening.
Dovetail on aluminum profile, allows you to insert or remove polycarbonate front cover,
without remove barriers from wall.
It is possible to adjust beams position at required height by loosening locking screw on each
board and making them slide inside guide. After this lock screws re-tighten them.
SADRIN barrier is designed to be immune to any disturb given by cell phones used in
proximity of it, not generating false alarms and maintaining its operating characteristics.
SADRIN is protected by blinding sunlight up to 300,000 lux, and at any case it is suggested to
check solar rotation in horizon to avoid direct sunlight.
It is possible to add up to 8 expansions to motherboard, to realize a barriers composed by 10
different beams, in a profile length up to 4m.
The new top cap design is studied to simplify the fixing of barrier to wall, without needs to drill
aluminum profile.

2. MOUNTING
1. Remove devices from carton pipe by applying pressure to side of it to facilitate spillage;
2. Remove top caps and remove IR plastic profile for aluminum.
If you need to shorten profile, cut it paying attention to avoid that any metal slag falls onto boards;
3. Insert square gasket in base cap;
4. Insert the cable gland gasket into groove;
5. Cut cable gland gasket at desired diameter;
6. Insert base cap in aluminum profile, paying attention that gasket is attached to metal;

8. On bottom cover cap of column there is a small drop to be incised to ensure drainage of rainwater that
could accumulate inside closure;
9. Fix to wall all structure (it is possible to adjust position of column, horizontally and vertically, through
slots on base caps)
10. After installation and alignment, hang IR profile to aluminum and close top caps with the supplied
screws.

3. INSTALLATION
Adjust beams height by loosening screws on the boards, and positioning at requested height, make connections
to terminal blocks and seal cable passages to prevent entry of water and insects.
Make sure all boards screws are tightened so that there is a physical contact between boards and aluminum
profile, to obtain an electric screening for prevent interferences.
Select and activate, through dip switches, the number of beams installed in barrier.
Make sure that expansions are properly connected (OUT>IN).
BEAM: move ON DIPSWITCH up to
corresponding number of expansions present
in barriers. The missed activation of
DIPSWITCH exclude relative beam operation.
(Example: 6 expansions added)
AND: in ON activates double-beam detection
(time delay 500 msec)
FAST: single-beam detection
(with faster time delay 100 msec)
Board fixing screw
LED SYNC: indicates the operation of the
synchronism

Power on barriers and check SYNC LEDs are flashing on both Transmitter
and Receiver mother boards. In case whereby only TX LED is on, check
synchronism connection.
Test function of barrier interrupting a pair of beams at a time, this must report
an ALARM event, signaled by RED LED and relay opening.
After test, complete installation choosing desired operation mode for the
barrier, as shown in table below.
After programming, if desired, is possible to turn off LED ALARM on mother boards by a jumper. Close
barriers hanging plastic IR profile on aluminum and closing the top caps.

4. CONNECTIONS
Use screened cables for connection, linking screen to negative of supply -12VDC (GND) on terminal block. In
addition to ordinary supply cables, tamper and alarm relay, you MUST connect transmitter side to receiver
SADRIN TX - SADRIN RX with a two-wire for the synchronization (+sync TX to + SincRX) (-sync TX to, -
sync RX).
Only for expansions MUST be set in ON a DIPSWITCH (3-10) on relative bench. Beam 1 and 2
always selected, because built-in motherboard.

5.CABLES & CABLING
Cablings must be done by two separate cables:
oOne (type screened 0.5 mm ² minimum) supplies barrier and allows the transmission of the alarm
signal and the tamper.
oOne (type screened 0.22 mm ² minimum) is synchronism cable to link TX and RX.
The screen of these cables must be connected to negative of 13.8 VDC in terminal
blocks of each column.

7.F.A.Q.
Barrier remains in alarm
Mare sure on both columns synchronism has been wired in
correct way and check presence of blinking LEDs on both
RX and TX;
Make sure DIPSWITCHES configuration is correct;
Make sure all expansions are well connected by flat cable;
Make sure installation has been made within max range
(especially in white colour).
Barrier gives false alarms
Make sure no animals or obstacles are interesting beams
range, in case not, if possible activate AND operation mode;
Make sure receiver column is not perpendicularly stricken
by sunrays;
Make sure voltage on terminal block is higher than 12,6
Vdc;
Use a screened cable for power, contact and syncronism
wiring, connecting screen to negative of supply to terminal
block (GND);
Install columns in “stellar” configuration avoiding “cascade”
one;
Use where possible a “linear” power supply, avoiding
switching one;
For installation distance under 1,5m remove lenses to get a
more accurate signal.
