SIEMENS FDOOT241-9 Fire Detection Module

Siemens FDOOT241-9 Fire Detection Module (Multi-sensor Smoke Detector – SINTESO Series)

 

 

The Siemens FDOOT241-9 is an addressable multi-sensor fire detector from the SINTESO S-line series. It combines optical smoke detection + thermal sensors to detect both smoldering and fast-flaming fires with high accuracy. It is designed for use in Siemens intelligent fire alarm systems (FDnet / collective systems depending on panel type).

• Supports intelligent fire detection algorithms (ASAtechnology)

Key Features

• Multi-sensor detection (smoke + heat)
• High false-alarm immunity (ASA signal processing)
• Optical scattering chamber design for accuracy
• Configurable detection modes (smoke / heat / combined)
• Loop-addressable communication system
• Suitable for complex environments (dust, humidity, industrial areas)

Applications

• Office buildings
• Industrial factories
• Warehouses
• Shopping malls
• Hospitals
• Airports
• Hotels and public infrastructure
• High-risk automation environments
