Siemens FDOOT441 Intelligent Detector

Siemens FDOOT441

The Siemens Intelligent Detector i s an advanced, multi-criteria fire detector. That incorporates a redundant, optical/thermal sensor. Intelligent Detector Model uses a unique forward/backward light-scattering technology. Providing state-of-the-art, unparalleled fire detection to the widest range.

They use a unique forward-backward light-scattering technology providing state-of-the-art. Intelligent Detector i s programmable as a high-sensitivity detector. And meets the requirements Standard as a Very Early Warning Fire Detector.

Each of these multi-purpose, addressable detectors offers a full and modern solution. To meet the detection needs of commercial facilities. Can b e field programmed for simultaneous and/or independent functionality. Depending upon the precise customer and application requirements. The detector can utilize the optical and heat sensors for enhanced multi-criteria fire detection. And provide independent outputs for heat detection. Any combination of the sensors i s possible

The detector is very versatile, and meets the fo llowing fire-industry standards:

Multi-criteria fire detector ( UL 268).

Heat detector ( UL 521) with five (5) possible field-selectable temperatures; combined with four (4) rate-of-rise options.

Direct, in-duct (plenum) detector ( UL 268A).

Supervisory monitoring for temperature ranges NFPA 76 (Telco Standard) as VEWFD.

Low-temperature warning signal at 40°F (4.4°C) for sprinkler systems, per NFPA 25 / NFPA 72.
