Foster anti-intrusion barrier
WARNING!
- Observe the minimum distances
between the Tx and Rx barriers
(see table on page 16)
- Power the device using the 13.8 Vdc
stabilised voltage only
- In order for the barrier to work
correctly, ensure the power voltage
never falls below 12Vcc.
- We recommend you switch on the
temperature control system (24Vac)

General installation instructions
1. After installing the barrier, make sure that it is perfectly closed with the watertight
covers supplied.
2. Use the cable clamps supplied to insert the cable in the lower section.
3. Make sure that the path between the sensors is free and that there are no obstacles
that could affect the communication between the optical assemblies of the transmitters
and receivers (i.e. branches, plants, leaves, etc. that could interfere with the beams).
4. Verify that the optical path of the transmitter used by the receiver barrier is not
exposed to direct sunlight at dawn and sunset.
5. Do not stack several barriers, as this could cause the transmitters to interfere with
several receivers. It is usually advisable to reverse the transmitters and receivers
when installing the barriers (see page 6 in Figure 1-2).
6. Do not use switching power supplies that cause disturbance to power supplies when
amplified by optically synchronized systems.

Example of how to protect an independent building
The Foster barriers come with crossed beams for maximum protection.
For visibility purposes, the beams in this drawing are linear.

WARNING!
- Always pole-mount two TX and/or RX columns of the same group, to
avoid possible communication disturbances/interferences.
- Ensure no interference is caused by the presence of photocells for
automatic gates or microwave sensors, as these may blind the
barriers.

Aligning the barriers
Note: The pre-alignment of barriers, which is sufficient for the vast majority of
installations, is carried out by the manufacturer during the final testing phase.
Initial manual alignment
To correctly align the barriers after installation, place the optical assemblies of the
transmitters and receivers facing one another, manually moving them to adjust them
vertically and horizontally.
1. Horizontal and
vertical orientation
Foster – Installation and Use Manual Page 10 of 16
Aligning the instrumentation
Note: Foster barriers are already pre-aligned by the manufacturer. In the event of
problems arising during alignment, follow the procedure described below.
Aligning the transmitter assembly (transmitter)
Reference value: approx 4V (see pages 12 and 13)
1. Connect the tester to one of the main
RX expansion boards using the small
(red-black) cable supplied.
2. Move the test jumper on the TX base board
to position ON
3. Move the jumper test on the first
TX expansion board to position ON.
Foster – Installation and Use Manual Page 11 of 16
4. Manually adjust the optics of the
first TX expansion board in
order to display the maximum
voltage value on the tester, i.e.
approx 4 Volts (voltage values
beyond 4 Volts are to be
considered optimal).
Some multimeters might display
a voltage that is up to 50% lower.
It is very important to direct the
lens towards the centre of the
receiving barrier (RX) installed
frontally.
Note: It is important to ensure all the
red leds on the RX optics electronics
are switched off. In the event of some
or all of the leds being on, direct the
TX optics until they switch of.
5. Remove the jumper test from the first TX expansion board in the lower section.
6. Repeat the alignment operation in the same way for all the remaining TX
expansion boards.
Aligning the receiver assembly (receiver)
1. Move the test jumper on the base TX
board to position ON.
2. Insert the jumper test in one of the central TX expansion boards to position ON.
Foster – Installation and Use Manual Page 12 of 16
3. Connect the tester to the test point of the first
RX expansion board in the lower section
using the small (red-black) cable supplied.
4. Move jumper MODE on the RX expansion
board to position TEST.
5. Manually adjust the optics of
the first RX expansion board in
order to display the maximum
voltage value on the tester, i.e.
approx 4 Volts (voltage values
beyond 4 Volts are to be
considered optimal).
Some multimeters might display a
voltage that is up to 50% lower.
It is very important to direct the
lens towards the centre of the
transmitter barrier (TX) installed
frontally.
6. Repeat the alignment operation in the same way for all the remaining RX
expansion boards.
7. After completing all the alignment operations, move the jumper of the base TX
board to position OFF.
8. Move all the jumpers of the TX expansion boards to position OFF.
9. Move all the jumpers of the RX expansion boards to position NORMAL.
10.Models with two lenses: verify that the barrier generates an alarm signal when
each assembly with two lenses is covered.
Models with one lens: verify that the barrier generates an alarm signal when each
assembly with one lens is covered.

Settings and programming
Description of indicators (LEDs)
FOSTER RX boards have 6 indicators (LEDs) used for control purposes, which can
be enabled by moving the jumper on the two-pin connector marked as LEDs to
position ON.
It is generally advisable to move the jumper back to position OFF at the end of the
testing phase.
LED S.LOW: low signal (DISQUALIFICATION)
LED S.LOW switches on to indicate the presence of “intense mist”. If intense
mist is detected, the barrier does not initially generate an alarm message
signalling a missing signal, but switches the S.LOW LED on, issuing the signal
DISQUALIFICATION on the terminal board (open collector).
LED MASK: Blinding signal
LED MASK switches on and blinks to signal that the infrared signal detected has
a modulated intensity above the one of the signal used.
Note: this LED is generally OFF in ordinary operating conditions. If the LED
continues to be lighted or blink, increase the blinding immunity by adjusting
trimmer MASK (turn it clockwise to increase sensitivity).
LED DETECT: Beam interruption detection
Regardless of the alarm output resulting from the tripping delay, which can be
adjusted with trimmer SPEED, LED DETECT always switches on when the
beams of the barriers are obstructed for a long or short period of time.
Note: this LED is generally OFF in ordinary operating conditions. The LED blinks
if one or more transmitter signals are not detected.
The LED lights permanently if no signals are detected from all the transmitters or
if one or more receivers are blinded or incorrectly aligned.
LED ALM: Alarm acknowledgement
This LED is normally OFF and switches on to signal the presence of an alarm.
The alarms of FOSTER barriers depend on the tripping delay set on trimmer
SPEED, which can range from a minimum of 50 mSec to
500 mSec (turn the trimmer clockwise to increase the delay).
LED HTR: Heating system enabling acknowledgement
FOSTER barriers have an automatic heating system with electronic control that
guarantees a minimum internal temperature of 17°C in all environmental
conditions.
If the LED is on, the heating system is working correctly.
POWER: power supply
LED POWER is the only one that is permanently on in ordinary operating
conditions. It is used to indicate that the board is correctly powered.
Foster – Installation and Use Manual Page 14 of 16
Description of characteristics and jumper settings
FOSTER RX boards can be programmed in different configurations by means of
the jumpers.
RX BOARD BEAM (preset by manufacturer)
Use all the jumpers that correspond to the number of receivers fitted on the
barrier (if the barrier has 4 double or single lenses, move jumpers to positions 3
and 4).
TX BOARD BEAM (preset by manufacturer)
Enable only the jumper that refers to the TX optics fitted on the barrier (for
example if the barrier has 4 beams, move the jumper to position 4).
AND
The selection of the ON mode enables to attain the random AND of two beams,
which means that an alarm is generated only if at least two beams generate an
alarm.
This applies to all the beams used both on transmitters and receivers.
This function can also be programmed remotely through the 0 Volt command on
the terminal board.
SPEED TRIMMER
Trimmer for the adjustment of the tripping time (50 msec - 500 msec).
MASK TRIMMER
Trimmer to adjust the sensitivity of the anti-blinding device (generally preset by
manufacturer).
LEDS
If moved to position ON, this jumper enables the LEDs.
NOISE (RX)
This jumper has to be programmed if interference from transformers, inverters,
etc. is detected.
S. LOW: low signal (DISQUALIFICATION)
This jumper has to be programmed if intense mist is detected.
Note:
The S. LOW and MASK outputs provide a transistor NPN that is normally open
and closes towards 0V when the output is active.
