It is not always possible to hard-wire sensors to the location requiring monitoring. GJD have recognised this and developed the RFX wireless detection system to be used independently or in combination with hard-wired systems.
The Opal RFX detection signals are radio transmitted by 433.92MHz frequency to the 3 channel receiver, which can be positioned in line of sight up to 150 metres away from the actual detectors.
The sensors are all individually identified with one of over 16 million possible codes. For ease of set-up the Opal RFX incorporates a simple plug in code memory transfer system to the receiver.
