SIEMENS FDA221
Product Features
FDA221 series detectors are very early warning dual wavelength (blue and infrared) smoke detectors designed to protect small business critical environments up to 500 m².
The detector works by continuously drawing air into sampling holes in a network of pipes.
The air is passed into a uniquely designed detection chamber where light scattering technology detects the presence of a very small amount of smoke.
FDA221 detectors can communicate directly over FDnet/C-NET loops (with an optional FDCC221S communication interface), so there is no need for separate relay or network connections.
