FS24X-911 3IR AL M25 FM/EN54


The FS24X multi-spectrum Triple IR (IR/IR/IR/Visible) Flame Detector, is one of the FSX family of advanced technology Electro-Optical fire and flame detectors. WideBand IR™, WideBand 4.3 micron IR™, and Visible detection technology with sophisticated software algorithms delivers the highest fire detection performance combined with optimal false alarm rejection. Unlike narrow-band detectors, the WideBand IR™ Infrared technology using high-speed solid-state Quantum sensors allows detection of most types of fires, hydrocarbon and non-hydrocarbon, in all weather conditions.

FS24X - Aluminium, M25, ATEX/IECEx, FM3260, EN54-10.
Advanced true triple IR Flame Detector for Hazardous Industrial areas.
