The radiocontrol Relco Code RP0543B is a transmitter operating at

433,92 MHz in AM/ASK modulation. It has been designed for use inside

switching boxes and operate in automatic closing systems, anti-burglar

systems and access control systems, thanks to its very high security coding

system (Keeloq ® Hopping code). The security code sent by radio

changes at each activation, avoiding any scanning and copying risk. A

special algorithm allows to keep synchronised transmitter and receiver.

The antenna is realized on the circuit board.

The RF transmission is carried out with a short between the 2 wires of

the input cable. These can be connected to an external push-button.

ATTENTION

The range of the transmitter, which in open space can be about 10 - 15

m, depends a lot by installation conditions and is much affected by metallic

elements as walls or pipes close to the fixing point.

DO NOT insert the product inside metallic boxes as the radio signal

could be completely shielded.

The product fully complies with the European Directives 99/5/CE,

2004/108/CE, 2006/95/CE and, FCC Rules Part 15.
