Duevi Photon System Installation Manuals

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
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.

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
