GJD Opal RFX External PIR Sensors and Receivers

GJD410 RFX Kit

Contains 3 Opal RFX wireless 35m PIRs and 1 GJD017 RFX 3 channel receiver.

GJD018 GJD RFX Wireless 35m External PIR Sensor

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.

GJD017 RFX-3 Receiver

An IP65 rated 3-channel receiver, 150 metres line of sight, 3x Volt free contacts as well as lighting control outputs.

The RFX-3 receiver monitors the active state of up to three Opal RFX passive infrared detectors. The RFX-3 can be mounted externally or internally with a line of sight reception distance of up to 150 metres to the detector(s).

    A piece of kit up to the usual standards of GJD. Easily fitted and meets the spec advertised. Range of sensors to the receiver was exceptional even through walls (which i expected to be a prob). Detection zones on sensors very good and programming easy.As usual prompt service and delivery from Alert

    My impression is that both the the sensor and receiver are good quality, well engineered, and versatile products with which an experienced installer can custom build systems for almost unlimited possible applications. When I had a query about optimum siting and masking of the sensor a phone call to the help number on the instruction sheet quickly got me the answer. When I placed the on-line order with Alert I received an email within the hour telling me that the parcel had already been dispatched to me in SW France.

    This external sensor meets the need to detect at a distance without wiring, so can be very adaptable. I use them on farm buildings to operate the outside lighting and being waterproof they can go almost anywhere. Battery life is impressively long, so all in all a useful piece of kit.
