Cerberus FDA241 ASD Smoke Detector


The Cerberus FDA241 series of Detectors are a very early warning dual wavelength (blue and infrared) Smoke Detectors designed to protect small business-critical environments up to 800 m².

The FDA241 Detector works by continually drawing air into sampling holes in a pipe network. The air is passed into a uniquely designed detection chamber where light scattering technology detects the presence of very small amounts of smoke.
 
The Cerberus FDA241 can communicate directly on the FDnet/C-NET loops (with an optional FDCC221S communication interface)‚ so there is no need for separate relay or network connections.
