Infrared smoke detector FDA241

photoelectricsuctionaddressable

Product description
The FDA241 aspirating smoke detector by Siemens is a very early warning dual-wavelength (blue and infrared) system designed to protect business-critical areas up to 800 m². The detector continuously samples air via a pipe network and detects minute smoke particles using light-scattering technology. It supports direct communication on FDnet/C-NET loops (optional FDCC221S interface).
