The wireless Opal RFX external passive infrared intruder 

detector design to detect and transmit reliable event 

based triggers to the weatherproof RFX-3 Receiver. These 

combined units enable the simultaneous or individual 

control of cameras, VCR’s, DVR’s and virtually all low-

voltage switching requirements.

The weatherproof receiver with front and rear tamper 

output can be positioned in line of sight up to 150m away. 

The active state of up to 3 Opal RFX PIR’s is constantly 

monitored. These signals are directed to their respective 

volt free outputs and in addition there are a further eight 

individual monitoring and information outputs.

The RFX-3 Receiver monitors the active state of up to 

three Opal RFX passive infra red detectors. 

The RFX-3 Receiver can be mounted externally or 

internally. The transmission distance of 150m can be 

obtained if the detectors are in true line of sight to the 

receiver. When installing the RFX-3 Receiver internally, the 

transmission distance of 150m will be reduced depending 

on the thickness and type of material structure the radio 

signals have to pass through or around.

It is advisable to conduct an RF continuity test when 

mounting the receiver internally to ensure that the radio 

signals can be received in the desired locations. (RF 

continuity test page 3).

WIRELESS TRANSMISSION

Each detector transmits radio signals to the receiver and 

has over 16.7 million individual codes. The receiver only 

responds to the transmitter that has been linked to a 

channel to identify it. 

The receiver can only analyse this information after the 

individual code has been transferred via the secure wire 

code learning link. This transfer is only required on the 

initial setup, any subsequent changes to the detector 

programming will be relayed by radio automatically to the 

receiver. (programming chart - page 3).
