Siemens DBZ1194 Detector Protection Cage

DBZ1194 is a protective cage that is slipped over a ceiling-mounted detector and protects the device against mechanical impacts and collisions. Its body has a diameter of Ø158.5 mm and a height of 126 mm, with a mounting hole spacing of 161.7 mm; therefore, the mounting holes are marked on the circumference of the detector base according to this measurement. For the cage to seat properly, the detector must be equipped with a FDB293 humid volume or FDB295 wet volume additional base; it is not attached directly to the standard base. The accessory, weighing 0.138 kg, is supplied under Siemens order number BPZ:4677110001. Since it has no electrical function, it can be used without distinction in both addressable and conventional systems.
