General description of the system

The Photon system by Deitech, in its basic configuration, is
made of two bars absolutely identical (Fig. 1), placed at the two
ends of the area to be controlled thus creating an “infrared
barrier”; the bars are connected with just one cable to a hub
(Fig. 2), that, placed in the Control Unit, controls the whole
system. The bars are used for both transmission and reception
of the beams, work in couple and exists in different versions:
from 50 to 200 cm height, with or without heather, with maximum
range 25, 50 and 80 meters. They have all the same design; are
made of an aluminium body with a black polycarbonate cover
and two caps of the same colour.

On the “ROTAX” cap (Fig. 3) you can

find the connection terminals and the
ROTAX system for the orientation of

the beams. On the “NUMBER” cap

(Fig. 4) there is the selector for the ID
number to assign to the bar and, in the
models with heater, the terminal blocks
for heater power supply. Through a four
wires cable plus shield, the barriers
(from ROTAX cap) will be connected to
the hub; the connection could be a star
or in series so that it can easily adjust
to the different installation
requirements.

The hub controls the correct operation of the barriers, allows the configuration of the system
and concentrate the connexion with the control panel. The hub will manage up to a maximum
of four couples, that can be installed even in the same area and the beams will not interfere
between themselves. The four couples can be of different heights and different range but the
bars of each couple must be the same. For each couple the hub will allow to set different
operation parameters (see HUB-TC Manual for details) and manage single stand-by inputs.

The alarm output toward the control panel are different for each couple, while the technical
outputs (tamper, disqualification, failure) are common for all the couples managed by the hub.

If the installation will require more than four couples, then more hub are needed.

THE BARS

It’s absolutely fundamental to install the couple of bars properly, each couple must be placed in order

to protect the passage through which an intruder could pass. In order to determine the correct mounting
height of the bar, it must be taken into consideration that the first beam (and the last) is placed at about
20 cm from the end of the bar and that between the other beams there are 25 cm. The barrier can be
placed upside down to connect the hub either from above or from below, but it is mandatory that each
couple is installed in the same position. All the Photon barriers have a patented system that allows a
correct horizontal alignment of the beams (ROTAX). This system will enable the installer to install them

Fig.4 – number cap

PHOTON SYSTEM – Installation Guide v8.0 - pag.2

on surfaces that not necessarily are placed in front (Fig. 5).
Oblique installations can than be easily made (Fig. 6) with a
maximum angle of 90° between the walls i.e. the barriers
can be installed on the same wall (Fig. 7). The ROTAX (Fig.

17) is the rotating element that has to be used in order to
direct all the beams in the range +/- 90°.

The bars are equipped with two tamper systems. The first
one (that cannot be deactivated) is located on the cap’s
opening and goes in alarm every time the cap is open. The
second will reveal the removal of the bar from the surface
on which it is installed and can be deactivated if not used.

Inside the bar there are two red led that can flash if the
hub have the led option enabled: one will signal a tamper
alarm i.e. that at least one of the four tampers is open, the
other one light on when the barrier is in “alarm” condition.

The ice can divert the direction of the beams; it is possible
to order a version of barrier with integrated heating system

(the not “heated” ones cannot be modified later). These bars

are suggested for external installations and anyway in cold
and humid environments. The heating system, managed by
a thermostat, will guarantee the functioning up to -20° C..

Cabling the bars

After having set where the bars have to be placed, it will be necessary to position the connecting wires
between the hub and the barriers. In a standard installation (bars positioned at a maximum of 200-300
mts from the hub) a standard 4 wire cable (two for power supply 0,75 mm2, 2 for the serial communication
0,22 mm2) and shield.

The number of possible connection typologies is quite wide and for each one of that the maximum
length of the cable may vary; Fig. 23 represents some examples with the maximum cable length.
Warning the maximum length of a cable connected to a single barrier is 1000 mts.

For the connection of the wirings, there are available waterproof interconnection boxes (Fig. 18), that
contain a terminal blocks that allows to derive from the bus two wires for the couple.

Fig. 24 represents an example of a connection of a complete system.

If the bars are the heated version, for the installation of the heating power cables you have to refer to
adding section of this manual.

Fixing the bars

The bars must be fixed on walls or supports that should be as much as possible flat and plumb; in case
it is advisable to use plies to correct and to fill the surface making it flat. If there is no intention to use the
anti-removal tamper it is sufficient to lean the bar on the support and, after having plumbed it, mark the
holes for the screws trough the holes of the two caps (see drawings attached at the end of this guide).

WARNING: TIGHTEN ONLY ONE OF TWO FIXING SCREWS AND LEAVE MOVING POSSIBILITY
TO THE SECOND SCREW, TO ENSURE THE PROFILE OF BARRIER FREE TO EXPAND /
CONTRACT FOR THERMAL EXPANSION.
BAR MUST NOT BEND UNDER ANY CONDITION, OTHERWISE IT WILL AFFECT ITS PROPER
OPERATION.

Anti-removal tamper activation on the bars (optional)

The anti-removal tampers are two waterproof buttons which are integrated in the rear of each cap and

are encased in order to avoid tampering attemps from outside..

PHOTON SYSTEM – Installation Guide v8.0 - pag.3

In order to keep each tamper pressed it is sufficient a head of a screw that stands out for from the wall
about 3/4 mm. The anti-removal system requires a certain precision of installation. For this purpose a
mask is supplied that shows the exact point where the screw has to be inserted. The head of this screw
will stand out for minimum 3 mm and not more 4 mm. If plies have been used, then the distance of the

screw’s head must be adjusted according to the needs. Once the bars have been fixed, remove the

jumper J1 on the ROTAX cap and J2 from the NUMBER cap and verify with a tester positioned on the
two pins of the J1 or J2 jumpers that the contact is closed; if it appear as open than that mean that the
screw does not stand out enough. Warning do not protrude the screw more than 4 mm in order not to
damage the micro-switch button.

Cable connection inside the bars

The cable connection is made in the following steps:

1) Prepare the cable (Fig. 8 A / B).

2) Insert the cable in the cable gland (Fig 9).

3) Fold the cable shield backwards and lean it on the metallic holder (Fig 8 C / D).

4) Block with a strip the cable to the holder (Fig 8 E / F).

5) Cut, shear and fix the 4 wires into the terminal blocks and tighten the cable gland (Fig 10).

WARNING: USE EXTRA CARE IN THE TIGHTENING OF THE CABLE GLAND. WRONG CLOSING
AFFECTS HEAVILY THE WEATHERPROOF IP65 LEVEL OF THE BARRIER AND WILL VOID THE
PRODUCT WARRANTY.

Settings of the bars

In the bars there are two settings to do. The first one will enable the anti-removal tamper. Whenever
you want to activate it you will have to remove the two jumpers that are placed in the NUMBER and in
the ROTAX caps. The other relates to the ID number of each bar (address).

Addressing the bars

Each Hub can manage up to four couples (i.e. 8 bars) and each bar must be precisely identified with
a univocal number on the bus. This will be set by jumper that can be found in the cap “NUMBER”.

Fig 10

PHOTON SYSTEM – Installation Guide v8.0 - pag.4

The ID number of the bar (address) must be set as follows:

 1 and 2 for the first couple (zone ‘A’),

 3 and 4 for the second couple (zone ‘B’)

 5 and 6 for the third couple (zone ‘C’)

 7 and 8 for the fourth couple (zone ‘D’).

NOT HEATED version has a double row of contacts on which a jumper is inserted in the position
corresponding to the address to assign to the bar (Fig 11).

Fig 11 – Addressing of the NOT HEATED version

HEATED version, due to the presence of the heater, has a single row of contacts on which a jumper
is inserted in the position corresponding to the address to assign to the bar (Fig 12). Pay great attention
to this, because due to the small space available, it is easy to fall into error.

The HUB-TC

Connection between HUB-TC and barriers

The connection with the bars can be made only through the 5 terminals of the hub (Fig. 25). Do not
connect the bars to different supplies than the one foreseen and be very careful not to invert the serial
poles S2 and S3. Fig. 24 represent an example of the connection of a complete system.

Terminals description:

S1 = Negative power supply (0V) minimum section 0,75mm2

S2 = RS485 pole A minimum section 0,22mm2

S3 = RS485 pole B minimum section 0,22mm2

S4 = Positive power supply (+12Vdc) minimum section 0,75mm2

GROUND = Shield of the cable

WARINING: THE CABLE SHIELD MUST BE CONNECTED BOTH ON THE BARS AND ON THE HUB SIDE.

Connection between HUB-TC and Control Panel

The hub is made in such a way that it can be installed inside the Control Panel Case or in any other
protected case. Use the holes foreseen in the Hub for its fixing. The connection will be made by the cabling
of the wires between the terminal blocks of the Hub (Fig 25) and the Control Panel.

It is recommended to use for the power supply at least two wires of minimum section 0,75 mm2.

WARNING:
CONNECT THE METALLIC BASE OF THE HUB TO THE ELECTRIC PLANT GROUND.

Settings on the HUB-TC

The HUB-TC allows you to centralize the monitoring and configuration of installed barriers couples,
through the use of 3 free software:

 PHOTON TEST HUB (barrier and cabling verification)

 PHOTON SETUP HUB (setting of the barrier parameters)

 PHOTON MONITOR HUB (real-time monitoring and activity log of the barriers)

For the use of the software you need to connect to the RS232 port of the Hub (Fig 25)

Switch on and check of the system

Once all the cabling have been done, it is necessary to verify the connection and correct setting of
the HUB.

WARNING. This is just a summary of what to do. Please see the HUB-TC manual for the step by
step procedure of system verification and programming of the system.

1) Set DIP1=ON, DIP2=ON and power the system. After few seconds the led is solid on. If the led is

off, check the power cables of the HUB.

2) Use the software PHOTON TEST HUB to verify that all the address of the connected bars are

detected by the software (1-2-3-4-5-6-7-8). If some bar is not detected, check that the addresses
on the bars and the connections are correct, then make again the test. Do not go to the next step
until any connected barrier is detected.

3) Use the software PHOTON SETUP HUB to program the working parameters of each couple.

WARNING: Enable only the barrier couples that are really connected to the system (A-B-C­D), otherwise the HUB will not start correctly and will signal continuously a FAILURE.

4) Set DIP2=OFF and press reset button on the HUB to restart.

5) After few seconds, check the proper operation of the Hub with the continuous quick flashing of led

(Fig 25). If the led is solid on or flashing in a different way, it means that the HUB is in FAILURE
mode, so you have to check again the previous steps (check the cables to the bars, the enabled
couples A-B-C-D, the correct addressing of the bars – Fig 11).

6) If the HUB gives tamper alarm and all the caps are already closed, please check the proper

closing of the caps. If some cap is open, then it is a correct alarm condition.

7) At this step you have to start the beam adjusting procedure and it is normal that, as it is not

performed yet, the HUB can give alarm or disqualification condition.
