Siemens FDOOT241-A3 Sinteso Multi-Sensor Detector — AlgoRex AnalogPLUS Modernization
FDOOT241-A3 (order number S54310-F10-A1) is a multi-sensor detector designed to transfer existing AlgoRex AnalogPLUS installations to Sinteso FDnet infrastructure without changing cables. It evaluates data from two optical scattered light sensors and two heat sensors together; ASAtechnology signal processing distinguishes fire indication from misleading environmental conditions. Since the same device operates in both AnalogPLUS and FDnet protocol, modernization can be carried out in stages: detectors first serve on AlgoRex panel, and when the panel is converted to FS20, the same devices remain in place. For installation it is mounted via FDB241 adapter to the existing DB1131A base and this combination achieves IP44 protection class. Compatibility within EN 54-5, EN 54-7, EN 54-17, EN 54-27 and EN 54-29 scope is recorded with VdS G211125 and LPCB 126bv/02 documents.
