The Eaton FXN922 is a conventional multi-mode (5 in 1) detector for Eaton conventional fire systems. Using the four-position switch on the back of the detector it can be set as an optical smoke detector, a photo-thermal detector or one of three heat detectors (rate of rise and two fixed temperature settings), and it is certified for use in all five modes. It is also compatible with JSB Bi-Wire systems. It mounts on the standard conventional base EFXN520 (supplied separately).
