The evaluation unit is located in a plastic box with cable grommets. The unit is connected to individual detection sensors (PDS) and input/output modules (PIO) using a data cable (twin-wire bus-bar). The unit contains 10 programmable outputs. These can be connected to a conventional security panel with the result that activation from any groups of PDS’s or the input status of any PIO module can be assigned to any output. The evaluation unit contains in addition eight double balanced inputs, which can be used for connection of other security system elements, e.g. PIR’s, IR beams, MW detectors and contacts.
