The PDM-E-I18T E-BUS PIR motion detector utilizes the patented MAGIC Mirror technology, which sets new standards in detection sensitivity and enables an extremely compact design. The innovative dual mirror design increases the focal length, which gives the detectors more homogeneous detection sensitivity, especially for wider areas. A new integrated white-light filtering system reduces false alarms caused by external light sources such as car headlights or lamps. For added peace of mind, the PDM-E-I18T 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.
