Introduction to the instructions and
warnings
This manual is intended only for qualified technical
installation personnel.
No information contained herein may be considered of
interest to the end user.
This manual refers to synchronizable photocells T90/F4S
and should not be used for other products.
Read the instructions carefully before
installing.
The installation must be performed
only by qualified technical personnel in
accordance with relevant legislation.
WARNING
Perform connections with cables that are
adequate to the current and voltage requirements and
comply with the product specifications.
In order not to affect their proper functioning, the
photocells must be properly aligned without using
reflections and must not interfere with other photocells,
whether they be of the same or of different types. It is
possible in fact, to encounter interference between pairs
of not-synchronized photocells, including more than four

pairs of synchronized photocells or other devices that emit
infrared light. Take all the necessary precautions in order
to eliminate this problem.
To understand the issues related to reflection and
interference between unsynchronized pairs see figure 2.
CAUTION: If the installation requires a distance between TX
and RX of less than 2.5 meters, then the TX and RX lenses
must be removed: otherwise their proper functioning
cannot be guaranteed. Whatever the case, the minimum
distance allowed is 80 centimetres.
WARNING: It is essential to change the configuration of the
jumpers when in the absence of voltage since they are only
read upon ignition and to prevent damage to components.
ATTENTION: in case of AC power supply, connect all TX and
RX with the same polarity.

Product description
The synchronized photocells versions T90/F4S are
presence detectors that use infrared technology, which
allow for the detection of obstacles in the optical axis
between the transmitter and receiver photocells, they can
be used for automatic entrances, for courtesy services and
monitoring passageways.
T90 photocells are compatible only with photocell column
series TRIX
Synchronization allows you to connect up to 4 pairs of
photocells without worrying that they may interfere with
each other. Synchronization is accomplished through
an additional wire that connects all the photocells
transmitters and receivers.
Synchronization is achieved with a photocell TX, called
MASTER, and is transmitted to the receiver coupled to it
and to all the other pairs of photocells available (called
SLAVE).
For these instructions, the transmitter photocell is called
TX photocell, the receiver photocell is called the RX
photocell, while one or more pairs of photocells (always
composed of an RX and a TX photocell) will be referred to
as photocells.
