SHIELDED LENSES – GREATER IMMUNITY TO INTERFERENCE
CDR 973 is a specifically designed range of next generation infrared security devices
for the protection of carriageways and pedestrian passageways fitted with automatic
opening and closing systems. The appliance is fitted with a new optical transmission
system that respects an infrared opening angle of +/- 5°. The management of both
the transmitter part and the receiver part is carried out by micro controller, giving the
advantage of greater precision in the generation of impulses transmitted via infrared
and this (once modulated according to a digital protocol that allows information
transfer from the transmitter to the receiver) eliminates the risk of blinding caused
by other infrared systems working on the same frequency and located in the vicinity.
This is a superior class appliance that will be available in three different containers in
order to solve all installation requirements.

CDR973EX Technical description

Infrared emission obtained by digital modulation of the carrier signal.
Reception with protocol demodulation and decoding allowing the transmitter to be
recognised.
It is possible to connect up to 3 pairs of photocells and synchronize the transmission
without interference; selection is carried out by means of a three-way dip-switch
located on the transmitter and the receiver and by interconnecting the three
transmitters using a two-wire cable (synchronism). The receiver does not require
any other form of interconnection.
Digitally controlled double relays are situated on the receiver card in order to
increase the safety of the appliance (at rest/alarm status control).
Jumper for selecting the output mode (potential free, N.C. or resistance 8,2kΩ
contacts).
Drop out delay selection via dip-switch (0, 2 seconds or 3 seconds).
High intensity LED (on the receiver) facilitating lens centring from a certain distance.
2 indicator LEDs on the receiver:
– green – when lit indicates the photoelectric cell is at rest;
– red – when lit indicates the photoelectric cell is in alarm, when flashing indicates
photoelectric cell failure.
Reinforced power supply tolerating voltages up to 40Vdc or 28Vac.

CLASS 3 PHOTOCELLS

The circuit board has been produced according to the requirements stipulated by the standards for electronic appliances that fall under category 3 of the EN
ISO 13849-1 (update of the EN954-1). At a practical level it covers the need to guarantee greater immunity to interference in the working environment that is
increasingly being polluted by disturbance. This has led to the technical evolution of both the transmitter part as well as the receiver part based on the criteria
“resistance to single failure” that guarantees the maintenance of the safety level even when faced with electrical problems regarding one or more components within
the device (transmitter or receiver)
