Whileeach product has the same user interface on the Energy Management System (EMS) controller,different models and configurations may differ in behavior, types of fixture, fixture harnesses,wireless operation, and other aspects. Contact Carmanah if you would like to repurpose an E Seriesfrom its original model and configuration. Each system will be described in full later in this usermanual.3.2 Radio CommunicationRadio communication between the same products is always present in R820-E and R920-E systems and is anoption in R829-E systems. In addition to the E Series, Carmanah also manufactures larger F and G Seriesversions of the R920, R820, R829, and R247 products. Wireless communication works seamlessly betweenproducts regardless of whether they are E, F, or G Series. R820 and R920 systems will also activate each otherwhen a pedestrian pushes the push button.The radio modules use 2.4GHz DSSS (Direct Sequence Spread Spectrum) with an AES128 encrypted signal andhave been tested with clear line of sight (with no nearby interference or reflected signals) to 1,000 feet (305meters). Performance is reduced if clean line of sight is not possible.The E Series uses a low-profile antenna that does not require any special orientation or adjustment and isimmune to vandalism.
