The PDM-E-IXD18T E-BUS Dual motion detector offers reliable detection of intruders and high false alarm immunity. Its performance is based on an improved version of Vanderbilt`s Matchtec algorithm, which combines passive infrared (PIR) and microwave (MW) channels to make extraordinarily accurate decisions on motion within their detection zone. Intelligent processing routines analyse the relative strength of the IR and MW signals received from a moving object in order to make sound decisions. It is even possible to use multiple detectors in close proximity to each other, since the algorithm reduces interference between the MW modules. This increases flexibility in selecting the installation site. For added peace of mind, the PDM-E-IXD18T is offering an integrated anti-masking technology (monitoring against covering). All MAGIC BUS models are designed as addressable detectors on the E-BUS communication interface - a 2-wire serial BUS with multi-master properties. This dramatically reduces wiring, installation equipment and labor costs, while providing benefits of remote services. Each MAGIC BUS detector also includes an additional zone input for convenient connection of an additional external device, saving time and effort of having to wire back to the panel.
