The RN4/10-25. ChA by Optex is a 30' x 80' high security active infrared system (Channel A).

The Rednet(tm) Series of photobeams is a range of active infrared detectors designed to combine high levels of intruder detection with a low potential for false activation. The system utilizes an infrared transmission to synchronize transmitters and receivers and removes the need for hardwire synchronization cables between towers.

RN4 systems feature four high power transmitters and four receivers. Uniquely, each transmitter operates to all receivers and all receivers are operated by all transmitters. This combination creates a sixteen beam path 'net' which is difficult to compromise.

If your site requires the installation of multiple Rednet beam sets mounted in close proximity to each other, then care should be taken to select Rednet units with different frequencies or mount the unit in such a configuration where one transmitter cannot see another receiver from an adjacent zone. This will eliminate the possibility of crosstalk.


The Rednet(tm) system is simple to design and install as it is modular and has just five main components. To design a system, simply decide where the towers are to be positioned and measure the distance between these points. Choose the wall (RNW175) or free-standing (RNT175) towers and select the correct beam set for the distances between them. Towers come complete with all fixings and the electronics include heaters, thermostats, fixings and alignment aids.


The Rednet(tm) beam head contains a folded optical array to combine a long focal length with small head size. This creates narrow transmission and receiving angles to maximize performance. The heads also contain their own heater to ensure that the maximum amount of energy is directed to the section of the tower the beams operate in.
